C.P.U. - CENTRAL PROCESSOR UNIT: CODE - CPU 91B FUNCTION

The CPU-91B is the CENTRAL PROCESSING UNIT to control the system containing the

Microprocessor and associated PROMS and support devices.

PROGRAM EPROM

The program EPROM contains a fixed program of the system application. The EPROM is labelled to identify thesoftware version cross referred to in the SYSTEM HANDBOOK. SPEC EPROM

The SPEC EPROM contains the CONFIGURATION DETAILS specific to the system. It contains all the data to operate this particular application e.g., Number and address of inputs and outputs, Controls, audible drivers etc.

The EPROM is labelled with the system serial number.

WATCHDOG

AN LED "CPU ON" indicator with an open collector fail safe output.

The WATCHDOG facility continually monitors -

a) The 5V supply to logic. b) The +v alarm contact voltage c) The microprocessor is running

On failure of any of these the .CPU ON. LED will extinguish and the CPU output will switch off.

PIN SETTINGS

The CPU has two link settings (S3 and S4) to vary memory size and enable/disable write functions.

Details are shown below.

These are Factory set and should not be altered. Should a replacement CPU be fitted at any time these must be checked and set as shown.

ALTERATIONS

The full system details are held in the factory, referenced most readily by the SERIAL NUMBER. The SPEC EPROM and support documentation can be modified on request to the After Sales department.

SYSTEM SERIAL NUMBER

The system SERIAL NUMBER is engraved on the handle of the CPU and labelled on the SPEC EPROM.

3U Internal Regulator (REG-90A/91A)

NOTE: The 5V supply is not available as an output - do not attempt to use this supply for external use.

The system supply voltage is or can be unregulated and used for Lamp Voltage and Audible Supply. The '+V supply is internally regulated with limited current load rating. It is required to supply the small current load required by the alarm initiating contacts and control switches to ensure the input response time parameters are kept within the specified limits.

The REG-91 A should be used if the inputs are to be supplied independantly of the system

supply. This isolated input supply must match the voltage rating of the isolated I/O or input cards being used. i.e.,

24V requires a 81/0-91A 50V requires a 8I/0-92A etc

AUDIBLE ANNUNCIATOR - CODE: 31-810 The 31-810 Audible annunciator matches the 31 series control switches and is an option on the 03MLCS range of display fascias.

The Series 31 Audible is designed for operation from ac and dc supplies in the ranges 10-55V ac and 10-75V dc.

The supply voltage is connected to the audible with a choice of two sets of connections to select the

applicable voltage range. See connection diagrams. Additional connections provide a continuous or

pulsating sound output. This may be switched to enable the same audible to emit both types of sound in order to define priorities or provide two independent signals. Sound output is approx 100dB(A) at 0.1m. The output level is adjustable by means of an additional variable or fixed external resistance.

The audible annunciator is compact rugged and reliable electromagnetic buzzer driven bya solid state oscillator. It is packaged to match the front panel appearance by Series 31 rectangular (18 x 24mm), illuminated push button switches and indicators. The component is also mounted in the same size

(16mm dia), single round hole as the complimentary switches and indicators and may be butted up to adjacent components. Sound output frequency is approx. 2.8kHz.

1 INTRODUCTION 1.1 GENERAL

The ROCHESTER developed controlled alarm system MPAS-90 is a long established system with many thousands of units working world wide.

The original 8 bit units based on the Motorola 6802 Processor are now complimented by the 16 bit units usinq the 68000 Processor.

MPAS-90 by its fundamentally simple mechanical design offers excellent reliability and by virtue of the large range of firmware options coupled with in-built editing facilities offer the user a high level of flexibility. Basic units can

easily be upgraded allowing integration into larger computer based annunciator / logging systems.

1.2. ALARM SYSTEM REQUIREMENTS

The purpose of an industrial alarm system is to give visual and audible warning of an alarm (fault) or abnormal plant

condition Awide range ofwarning sequences are required to meet the various standards listed in the UK and the

USA (ISA-S18.1) alarm sequence tables.

ROCHESTER INSTRUMENTS have developed the system to meet

these requirements atan economical cost and providing a high degree of system flexibility.

An alarm way consists essentially of an input, followed by some logical decisions, leading to visual and audible outputs (disregarding any other auxiliary outputs which may be required). The inputs and outputs are determined

by the physical requirements such as the quantity of alarms (inputs) to be monitored and the type of display

required (large, small, remote, mimic etc). The logic decisions, however, are more universal, and the manner in which these logic decisions are dealt with form the basis ofthe system.

An alarm signal in general terms will cause the annunciator to flash and the audible to sound. The operator will mute the horn and convert the lamp to a steady signal by 'accepting' the alarm. When the alarm condition has

cleared the annunciator may be reset using the reset control switch.

Should first up discrimination be required where, by different flash rates for example, the operator can readily see

which of several alarms was first up (perhaps causing the others to go into an alarm state), then the system can be

setto make these logical decisions. Unrelated alarms may beexcluded from this first up group(s).

The INDIVIDUAL aspect allows logical decisions to be made for variables that can exist within the system eg the

a arm may or may not be in a first up group, the alarm may be controlled by one of the several control switches the alarm may be included in a group relay output, etc.

The firmware to control and hold all this information is also split into two i.e.,

1-

2.

PROGRAM FPROM This holds the base MPAS90 program along with the editor program and two

sequence tables. It is not accessible bythe user.

SPEC EPROM This holds all the information which is specific to each system, i.e., no. of alarms operating

sequence, grouping controls, horn grouping, manual / auto reset, locking / non locking etc.

NOTE Afeature which has been kept away from the SPEC EPROM is the ability of the user to select for normally open or closed initiating contacts. This is achieved by D.I.L. switches on the I/O cards without any chanae

to firmware.

a

Control switches supplied by ROCHESTER are always set and wired as normally open.

The Power Monitor input should also be setas normally open.

FIGURE 3 - MICROPROCESSOR CONTROLLED ALARM SYSTEM 1.3 THE SYSTEM

The alarm system firmware has to copewith the following variables:

1.3.5

The number of alarm inputs The number of control switch inputs The number of annunciator outputs The numberof auxiliary outputs (grouped) The number ofauxiliary outputs (individual)

1.3.6

The number of annunciator sequences (2 maximum software tables per system)

1.3.1 1.3.2

1.3.3 1.3.4

EXAMINING THESE POINTS IN DETAIL:

1.3.1

THE NUMBER OF ALARM INPUTS

The firmware must determine for each input whether:i) The input is analogue or digital ii) iii) iv) v)

IfAnalogue - is it HI-HI, HI, LO or LO-LO.

If Digital - is the field contacts Normally Open or Normally Closed (switch selectable on I/O Card)

It is locking (to capture fleeting faults) or non locking.

Is input time delay required ? (taking advantage ofthe processor's ability to provide software controlled time delay).

1.3.2

THE NUMBER OF CONTROL SWITCH INPUTS

Control switch inputs (64 max.) and alarm inputs (128 max) are added to give the total system input

requirements, to this must be added one input dedicated tosystem power monitor. In principle the control switches may be listed in theform type 'X' switch controlling group V (16 max) and connected to terminal X = Any type of control

Y= Either lessorequal to the total system fault inputs.

Z=Appropriate input terminal at I/O module - generally allocated after the alarm inputs.

In principle any two of the above sequences may be specified in a system but if, for instance table 1was specified as RS and table 2 as FS2 then considerable confusion could arise in the interpretation of the

output display, therefore great care is required when selecting sequences.

NOTE:

All first up sequence tables (F1 F3) can also give non-first up indication by the ability to assign each point into a F.U. or non F.U. group.

The LOGIC BOXES are standard depth single (3U) or double (6U) 19" wide euro crates. The boxes are designed to contain the C.P.U., the I/O, the relay cards and the regulator.

The size of LOGIC BOX (either 3U or 6U) is dependant on the system size, its number of alarms to be monitored, the number ofcontrol switches and the number oflamp outputs etc.

The LOGIC BOXES are constructed using a motherboard(s) such that the C.P.U. and regulator have their

ThSI? n/Nr ~determined' while the cards, be it I/O cards or relay cards, can be located in any other slot.

The LOGIC BOXES can be ordered front or rear mounted - the angle brackets are simply moved from back

to front to suit.

Two combined INSTRUCTION / SERVICE MANUALS and SYSTEM HANDBOOKS are issued free with each system. One is enclosed with the system, the other is posted to your Engineer prior to manufacture

for checking.

4.1.2

The Engineer must examine his set and assure himself that the proposed system is as he ordered Any

4.1.3

The Engineer must check the following:-

discrepancy found is better fixed during manufacture rather than when received on Site.

Logic box dimensions and whether front or rear mounted.

Display size and layout Auxiliary equipment dimensions and cabling details.

System specification

a) Number of ways b) Sequence for lamps c) Sequence for audibles d) Sequence for relays

e) Control Switches - number and type f) Repeaters g) Power supply

h) Display cable lengths

If in doubt, contact Rochester Instruments Engineering Department for assistance.

4.2

MOUNTING THE EQUIPMENT

4.2.1

UNPACKING

Unpack carefully, checking all items against Parts List in System Handbook. Observe any warning labels /

tape which may be attached to the equipment.

4.2.2

i) LOGIC BOX

Ensure the LOGIC BOX is mounted horizontally in a location free from excess moisture vibration heat and dust.

Allow access for maintenance, ensure that the CARDS can be easily removed and that future equipment to be assembled does not obstruct CARD removal.

Check the LOGIC BOX location with reference to the remote display ensuring that the specified length of display cable is sufficient to wire to the I/O CARDS. ii) POWER SUPPLY UNITS

Mount near to the LOGIC BOX.

Use mounting details supplied. (With some DC-DC Converters it is important to obey the mounting

instructions toallow air flow over heat sink).

The POWER SUPPLY UNITS dissipate heat and should therefore be mounted above orto the side of the LOGIC BOX if possible.

Supply Filters (SF-90 and SF-91) are a requirement for EMC protection purposes and must be fitted as near to the logic box supply terminals as possible or on the main incoming supply to a panel if no

transients will be generatedwithin panel.

iii)

DISPLAYS

Displays supplied by ROCHESTER INSTRUMENTS with the systems:-

Check the display cable lengths ordered are sufficient to route from the DISPLAY mountinq position to the LOGIC BOX. The DISPLAY cables exit the DISPLAY from the right viewed from the rear The standard cable length is 2 metres.

On DISPLAYS with more than 7 rows or where a large number of indicators are grouped together ensure

adequate ventilation is allowed - consult ROCHESTER INSTRUMENTS if in doubt Displays not supplied by ROCHESTER INSTRUMENTS:-

Wire to the appropriate output terminals designated on the 'ENGINEERING CHART in thP 'SY^TFM HANDBOOK'.

otdicivi

NOTE: To benefit fully from the design features of the MPAS-90 I/O Cards, care should be taken to arrange wiring such that the front terminal panels can be moved with wiring intact to allow card withdrawal. iv)

AUXILIARY EQUIPMENT

Check equipment parts list and drawings for mounting information, access requirements, possible cable lengths and anyfurther details required to install the auxiliary equipment.

4.3

CABLING

The CONNECTION DIAGRAM DRAWING in the 'SYSTEM HANDBOOK' gives the details of input and output connections for all card positions.

When preparing the wiring schedules for the system it is advisable to note the following points before proceeding.

4.3.1

CABLE - GENERAL

i) The INPUT and OUTPUT CARDS do not contain a common +ve terminal for either inputs or outputs

The appropnate commons are found on the REG unit or adjacent supply panel and are clearly identified on drawing and on HARDWARE.

ii) Alarm inputs have 4common REGULATED 24V supply terminals on the regulator on 3U logic boxes and

6 common REGULATED 24V supply terminals on 6U logic boxes. These are identified as "INPUT COMMONS".

THESE TERMINALS MUST NOT BE USED FOR ANY OTHER PURPOSE EXCEPT WHERE SPECIFIED

BY ROCHESTER INSTRUMENTS.

iii) All outputs including lamp outputs, group lamp outputs, group relay outputs have 4 common

hmUISm.^S 24V SUpply termina,s on the regulator on 3U logic boxes, and 5 common

UNREGULATED 24V supply terminals on the supply terminal panel in the case of6U logic boxes These are identified as "OUTPUT COMMONS" and "+24V" respectively.

iv) Aseparate voltage can be used to supply the field contacts if required. Use 8I/0-91A Cards for 24V

and 8I/0-92A for 50V in conjunction with the appropriate isolated regulator.

4.3.2

CABLING - ALARM INPUTS

i) Alarm input loop resistance is 1 Kohm maximum.

ii) The common +VE regulated wetting voltage per logic box for all alarm inputs can be used provided-

- Normally Open or Normally Closed volt free initiating contacts are used.

- The initiating contacts are in a non-hazardous 'safe' area.

- No alternative instructions are issued in the "SYSTEM HANDBOOK" with the system.

in) Multiple contacts per input are possible; in parallel for normally open; in series for normally closed

provided the loop resistance of 1KOhm is not exceeded.

iv) All spare ways or unwired inputs must be fitted with a shorting link if normally closed contacts are

specified.

v)

The initiating contacts must not be used for any other purpose unless advised bv 'ROCHESTER

INSTRUMENTS'.

y "'-"•'"" "=*

vi) Systems operating from inputs other than volt free contacts see special instructions in the 'SYSTEM HANDBOOK'.

vii) The input terminals can accommodate 1.5mm2 cables. It is recommended, however, that smaller rated cables are used to facilitate easy access to the front panel for internal access.

vin) To benefit fully from the design features of the MPAS-90 I/O Cards, care should be taken to arrange

wiring such that the front terminal panels can be moved with wiring intact to allow card withdrawal.

4.3.3

CABLING - CONTROL SWITCHES

i) The CONTROL SWITCHES all have volt-free normally open contacts, - dose to operate The following control switches require only an impulse to perform their function:

ACCEPT, FIRST UP ACCEPT, HORN CANCEL, RESET, FIRST OUT RESET

The following control switches maintain their control for theduration of their operation-

INHIBIT, LAMP TEST, GROUP LAMP TEST, FUNCTION TEST, (depending on mode of alarm) ii) If the control switches are mounted on a ROCHESTER INSTRUMENTS display they will be pre-wired

with a cable length matching the display's indicators cable.

iii) Control switches supplied loose or by others should be wired according to the 'SYSTEM HANDBOOK' instructions.

iv) When more that one set of control switches are connected to the same logic box ensure the inputs are correctly connected.

v) When more that one logic box is required, check the cascading / interconnection instructions carefully The data will be detailed in the 'SYSTEM HANDBOOK'.

vi) Two or more control switches can be connected in parallel to operate the control function.

NOTE: The control switch input circuit is the same as alarm inputs.

4.3.4

CABLING - LAMP AND DISPLAY OUTPUTS

I) The ROCHESTER INSTRUMENT'S display is pre-wired either by ribbon cable or multicore cable with a 2 metre standard free ended cable to connect to the I/O CARDS.

ii) Asingle heavy duty common +VE wire is normally supplied as the feed to all indicators (and audible if

fitted) on the display. - (Connect to "Output Common" on L.B.) iii) Aseparate common +ve wire is supplied as the feed to control switches (connect to "Input Common" on L.B.)

iv) Lamp and display output drivers are rated up to 63V max. 5 watts.

NOTE: The system firmware programme can allocate any output to any position in the display.

COMMISSIONING

The system is highly reliable. It is microprocessor controlled with the advantage of the high degree of reliability of microprocessors.

There are fewer discrete components than in conventional systems. The microprocessor is electrically protected from the outside world by input circuits with an extremely high noise protection specification. Interconnections are minimal with two part rear connectors used for maximum life and reliability.

Correct and careful commissioning will ensurethe system has a long trouble-free working life.

POWER DOWN SYSTEM BEFORE WITHDRAWING OR INSTALLING ANY CARD IN LOGIC BOX.

5.1

5.1.1

PRE-CHECKS

Check all cards are in correct position as shown in the 'SYSTEM HANDBOOK' (Logic Box General Arrangement drawing).

Check for correct supply voltage before connecting.

All card address switches are factory set. If cards are unplugged for any reason, they must be put back in same position.

5.1.2

Check I/O card contact mode switches (normally open / closed) as shown in the 'SYSTEM HANDBOOK' are as required - Ifnot, remove one card at a time and set switches to required condition.

5.1.3

Check installation including:-

5.1.3.1 Inputs from initiating contacts are correct mode and volts-free - all inputs should be connected to +V (Input common) terminals.

5.1.3.2 Control switch wiring-control switches should be normally open in all cases with one pole connected to +V (Input common) terminal.

5.1.3.3 Display wiring - takes care, short circuits can damage open collector drive transistors.

5.1.3.4 Check audible and relay outputs - similarly check for short circuits.

5.1.3.5 Check power supply unit wiring.

5.1.3.6 Check logic box earthing.

5.1.4

Equipment should be free from excess dirt, heat and moisture.

5.1.5

Check supplyvoltage and frequency to power supply unit.

Check transformer tapping is correct.

Check mains suppresser is connectedto the appropriate transformer tap.

Check DC input voltage to DC-DC regulators for magnitude and polarity.

SYSTEM OPERATION

5.2.1

Switch on power and check that "CPU ON" LED is lit.

5.2.2

If preferred, temporarily disconnect audible(s) (replace with a lamp) to avoid annoyance while checking alarms.

5.2.3

Check each alarm way in turn according to its sequence, including: Indicators Audibles

Auxiliary outputs Controls etc.

Return each alarm to normal, i.e., indicator and audible off, before proceeding to the next input. In the case of first up groups a second test can check the lamp sequences required by initiatinggrouped alarms.

5.2.4

Should plant conditions not allow the test to proceed, i.e., permanent fault, disconnect plant wiring and simulate alarm input using a wire link between input terminal and +V.

Jgz*^ i&i3ir

5.2.5

Continue until every condition has been checked.

5.2.6

Re-connect the Audible(s) and test (ifit was disconnected at start of testing see 5.2.2)

5.3

'SYSTEM HEALTHY" CHECK ('C.P.U. ON') Remove power monitor link and check "CPU ON" L.E.D. on C.P.U. goes off and that any auxiliary device connected to the C.P.U. terminal goes off. Replace link and check C.P.U. restores to healthy.

5.4

COMMISSIONING NOTES ON CONTROL SWITCHES

5.4.1

All control switches should be normally open and connected to a +V INPUT COMMON terminal..

5.4.2

Accept, first up accept, first out reset, reset and hom cancel switch functions are operated by a pulse, i.e., momentary action of the switch.

5.4.3

Lamp test, function test and inhibitfunctions are maintained for the duration of switch operation.

(See later note 5.4.8 on function test)

5.4.4

ACCEPT SWITCH

In non first up sequences the accept switch will mute the audible and steady all flashing indicators.

5.4.5

FIRST UP ACCEPT SWITCH

Used in dual flash first up sequences only (M7 and M8); two switches are required - accept and first up accept.

Stage I

The accept should be operated first to mute audible and change subsequent slow flash indicators to steady, leaving first up indicator flashing fast.

Stage II

Operation offirst up accept changes first up fast flash indicator to steady and thereby cancels the first up sequence. Any further alarm would then claim first up status. The first up accept switch, ifoperated first, would by-pass Stage I. Page 5.2

BI180890

BI180890

5.4.6

RESET SWITCH

For manual reset systems only.

Manual operation of a reset switch is required before 'accepted' alarms in the fault clear condition can return the indicator to OFF (and the fault clear audible to OFF iffitted).

5.4.7

LAMP TEST SWITCH

The lamp test switch is, in fact, more than a simple filament test. It checks the CPU I/O card address and

data links and output transistors.

Repeater lamp displays will be lamp tested with the main display since they are merely wired out in parallel at the output terminals. Therefore both displays will be tested as standard, but independent lamp testing is

available on some program versions - Consult Rochester.

Alamp test on arepeater display would be wired in parallel with the lamp test switch on the main display.

Group lamps and status indicators are not tested unless specified. These can be programmed on the main

lamp test input or separate input as required.

Lamp test will over-ride any flashing sequence for the duration of the lamp test switch operation but will not

otherwise interfere with the sequence.

Lamp test will notoperate auxiliary relay outputs.

5.4.8

FUNCTION TEST SWITCH

The function test switch tests all alarms as if in full alarm condition including all indicators audibles and

auxiliary outputs.

Take care that any auxiliaries in a control loop are by-passed or supervised during a function test.

Non-locking alarms will clear on release of the function test switch.

Locking - Auto reset alarms will have to be accepted to clear after a function test.

- Manual reset alarms will have to be accepted and reset to clear after a function test.

First up discrimination is not given on afunction test, i.e., all alarms flash at the same time. (All first-up) It is inadvisable to have more than one switch per group.

It is advisable to key lock a function test switch, to avoid unnecessary false alarm situation.

5.4.9

HORN CANCEL SWITCH

Ahorn cancel is a momentary action switch which does not interfere with the indicators.

5.4.10

FIRST OUT RESET SWITCH

FIRST UP GROUP TESTING

a) Check and reset each alarm individually before testing the first up sequence.

b) Bring up any alarm in first up group followed by other alarms in the group - check sequence is correct as per appropriate sequence table.

c) Accept and reset and repeat with another alarm in the same group asthe first up alarm

NOTE: When all alarms are clear and a function test is initiated on afirst up group, no discrimination is given All alarms will flash in same mode. (i.e. all as first up)

5.6

GROUP REPEATER LAMP TESTING a) Check each alarm in group operates the group lamp. b) Check alarms not in group do not operate group lamp.

-.

c) Check that group lamp reflashes. Operate any alarm in group and press the accept switch ie group

I^J

lamp goes steady. Operate another alarm in group and check that group lamp reflashes.

5.7

REED RELAY TESTING a) Check the output wiring / cabling is correctly connected.

b) Check contact configuration (normally open or normally closed) isas required.

(Note whether relays are normally energised or de-energised when checking contacts)

c) Usea meter (or data logger etc) to check output.

d) Operate each relay from alarm source and check mode is correct (e.g., fault to accept fault to reset or

fault to fault clear).

IF ANY PROBLEMS ARISE DURING TESTING USE TROUBLE SHOOTING SECTION TO IDENTIFY FAULT.

TROUBLE SHOOTING

TROUBLE SHOOTING INFORMATION GENERAL

The alarm system is designed to have a high degree of reliability. As previously detailed in the 'commissioning' section, if the system is correctly installed in the correct environment it will operate trouble-free for the duration ofits operational life. Inexpert or careless handling, harsh temperature/shock/moisture conditions will degrade the performance of the system.

Should malfunction occur, the following trouble shooting instructions give guidance to locating and curing the fault.

However, it is again stressed that the system, in particular the cards, must be handled with respect and knowledge,

and any rework to the boards or logic boxes should be left to ROCHESTER INSTRUMENTS or other experienced personnel.

The trouble shooting information details the fault area and possible solutions. The fault finding procedure per section is written in order of priority; Work through the sequence until the fault is found. Ifthe fault is still present, ROCHESTER INSTRUMENTS' engineers will give further assistance.

All major problems occurduring commissioning and are generally due to one offour reasons.

L,

1. Incorrect specification on the order.

2. Power supply problems.

3. Short circuit outputs (indicators, audibles, relays).

4. Inexpert handling (finger trouble).

7.1

TROUBLE SHOOTING - GENERAL FAULTS Faults of a more general nature are listed belowfor examination should malfunction occur.

7.1.1

NO RESPONSE FROM AN INPUT

- Incorrect installation - check input voltage and polarity - Power supply problems - check voltage levels.

W-

- Fleetingfault too fast, (i.e., alarm system will not respond to inputs of less than 16mS duration)

7.1.2

SYSTEM OPERATION WRONG

- Specification on order incorrect - check purchase order / specification.

- System handbook information does not alignwith order - check for any conflicting specification details.

- Wiring incorrect - check all wiring against Connection details in System Handbook.

Should the system operation be incorrect, inform ROCHESTER INSTRUMENTS' After Sales (01383 822911) to determine the cause and instigate correction process.

BI180890

7.2

TROUBLE SHOOTING - ALARM INPUTS

7.2.1

The standard input circuit is from clean contacts, whether normally open or normally closed and/or fleeting or maintained.

7.2.2

8 way DIL switches on the I/O card allows alteration to suit open or closed contacts.

7.2.3

There are several different input possibilities.

Check the 'SYSTEM HANDBOOK' and the installation

commissioning sections of this manual before proceeding with any trouble shooting to ensure compliance's with the ROCHESTER INSTRUMENTS' instructions.

7.2.4

TROUBLE SHOOTING - NO ALARM WILL INITIATE.

a) Check supply voltage, fuses, main polarity. See commissioning SECTION 6. b) Check Power Monitor connection to +V input common terminal is OK and check voltage level of +V terminals.

c) Check "CPU ON" LED is 'ON' - to 'reset' the microprocessor simply switch power off, after a small delay (10 sees) switch power on -"CPU ON" LED should be on. d) Check control switches are normally open and Power Monitor input is set for normally open as per System Handbook.

e) Check initiating contact wetting voltage is present. On normally closed contacts - input terminal voltage is +Ve. On normally open contacts - input terminal voltage is OV. In both instances voltages should alter on initiation. (These checks are at input terminal of I/O Card). f) Check microprocessor and EPROMS on C.P.U. are fitted in the correct sockets and secure.

g) Check 5V ±0.25V regulator output on motherboard. (On tracks 1 and 32 on CPU slot, and on tracks 1 and 30 on I/O slots) See section 7.8.2 on page 7.11.

h) Check I/O card DIL switch settings (see 'SYSTEM HANDBOOK'). i) Check no inhibit circuit is on.

7.2.5

TROUBLE SHOOTING - INDIVIDUAL ALARMS WILL NOT INITIATE

a) Check initiation by substituting initiating contact with a jumper link.

b) Check input contacts have the correct supply voltage and no other voltage is present; if necessary with the system supply switch off and isolated.

c) Check DIL switch settings on the I/O board. If the address switches are wrongly set, the output indication will be incorrect. If the mode (N/O - N/C) switch setting is wrong the associated alarms may not work.

d) Swap I/O Card for a known good one - remember to check address and mode DIL switch settings of other card before inserting into the slot.

NOTE: As each of the 10 slot positions in a 3U high crate have identically hard wired motherboard fitted edge connectors, the slot position is, electrically speaking, immaterial. The DIL switches on the board and not the position determine the card's operation, i.e., an I/O card can plug in any slot: obviously the connections to the card must be as specified in the "SYSTEM HANDBOOK". e) After card is proven check input circuitfor normally open / normally closed.

Check that closed, line and Open Circuit resistance is within specification.

Check wiring is correct. f) Check no inhibit circuit is on.

g) If a proven good I/O card and a proven alarm contact still fail to operate the alarm way then check system for:

i) Mechanical damage to front edgeblock connector, ii) Mechanical damage to Motherboard connector Page 7.2

BI180890

BI180890 7.2.6

TROUBLE SHOOTING - ALARMS WILL NOT CLEAR

a) Check mode (N/O - N/C) DIL switch on I/O card. b) Check input circuit - remove field wiring ifnecessary and use shorting link. c) Check reset switch circuit.

d) Check function test/lamp test circuits are correct, (i.e., normally open contacts) 7.2.8

GENERAL

The alarm system has 9 types of control switches:

">

7.3.1

Accept

7.3.2

Lamp test

7.3.3

Group lamp test

7.3.4

Reset

7.3.5

Function test

7.3.6

Horn cancel

7.3.7

First up accept

7.3.8

Inhibit

7.3.9

First Out Reset

The switches are mounted remotely from the logic box, either pre-wired in a ROCHESTER INSTRUMENTS display, or as loose items to be fitted to a panel.

The switches can be momentary on maintained action, illuminated or keylock type, dependent on the function or requirement.

The switch rating requirement is approx. 2mA per input as it is switching a standard input circuit only.

The control switches are usually from normally open contacts with a common +Ve (+V input common)

7.3.1.1

TROUBLE SHOOTING - CONTROL SWITCH SPECIFICATION

The control switch input circuit is identical to the alarm ways input circuit, using the normal input circuit on the 8 way I/O card, 16 way input card or l/R card.

7.3.1.2

TROUBLE SHOOTING - ACCEPT SWITCH

The operator accepts an initiated alarm by operating the accept switch. This silences the audible alarm and changes the lamps from a flashing to a steady state. Before proceeding check the specification and commissioning section. Consult the 'SYSTEM HANDBOOK' for sequences and alarm groupings relevant

f~*\

to accept switch(es).

Switch type - non illuminated - momentaryaction.

7.3.1.3

ROCHESTER INSTRUMENTS ALARM SYSTEMS DEFINITIONS

ACCEPT A control function which alters an annunciator in the flashing state to a steady state and simultaneously silences the audible.

ALARM Plant fault, abnormal condition, or warning requiring indication.

ANALOGUE INPUTS Inputs of analogue form wired into appropriate analogue cards to allow alarms to be derived from present trip points. See also INPUTS.

ANNUNCIATOR A visual indicator, sometimes referred to as a WINDOW.

AUDIBLE An audible warning signal used in conjunction with the visual indicators; also referred to as a hom.

AUTOMATIC RESET - See Reset

AUXILIARY OUTPUTS The main outputs from an alarm system are the individual annunciators for each input. All other outputs are referred to as AUXILIARY OUTPUTS, i.e., individual and group relays; individual and group repeat annunciators, first up indicator and audibles.

BEACONS A high powered indicator, generally a group repeat indicator.

CASCADING Interconnecting of a logic box to others as the first and subsequent systems overflow their limits of software and/or hardware.

CHANNELS - See "WAYS'.

CLEAR HORN A sequence which operates an auxiliary horn when an alarm clears. Only used with manual reset sequence. See sequence tables.

CLEAR HORN SUPPRESSION A refinement to the clear hom sequence whereby operation of the main audible (by another alarm) will suppress the less important clear horn. Clear horn sounds after main horn is accepted, and is silenced, when an accepted cleared alarm state exists and the alarm is reset.

CODES All assemblies used in the alarm system are coded. The codes must be referred to when ordering spares etc. Codes are also used to abbreviate alarm functions. See Codes list.

CONTROL SWITCHES The alarm is controlled by a number of control switches. Generally the switches are volt free normally open momentary action switches. However, inhibit switches may be maintained action.

The controls are:

^

ACCEPT FIRST UP ACCEPT (SEQ. M7 AND M8 ONLY) RESET LAMP TEST GROUP LAMP TEST FUNCTION TEST

HORN CANCEL (or SILENCE) INHIBIT

FIRST OUT RESET (SEQ. M13 ONLY)

DIGITAL INPUTS Inputs from normally open or normally closed initiating contacts. See also INPUTS. DISPLAY Array of annunciators driven by the alarm system, sometimes referred to as a FASCIA. Rochester offer a wide choice of display types and sizes.

DUAL FLASH FIRST UP A sequence, using two flash rates, to give first up discrimination. See sequence tables (M7 And M8).

EDITABLE SYSTEM Alarm system configuration data can be edited by the user by means of the RS232 Edit Port on the appropriate CPU. Edit mode is entered by operating a KEYSWITCH which takes system off-line during the edit process.

FAIL SAFE RELAY Arelay which is normally energised in the normal - non-alarm condition.

FIRST UP ACCEPT A Control switch function which accepts the first up alarm in a Dual Flash First Up sequence, thereby terminating the current first up indication. Used on sequence tables M7 and M8 only.

FIRST UP RESET

A control switch function which resets the first up alarm in an Intermittent Flash First Up

sequence, thereby terminating the current first up indication. Used on sequence table M13 only.

FIRST UP INDICATOR An indicator (generally incorporated within the first up accept switch) which illuminates when a first up alarm requires acceptance.

FIRST UP SEQUENCE An annunciator sequence used to discriminate between the first and subsequent alarms.

(See Single, Dual and Intermittent Flash First Up paras)

FLASH RATES The alarm annunciator flashing frequency.

FLEETING ALARM A momentary alarm condition as opposed to signal noise or voltage transient. The duration of the fleeting alarm would need to be sufficient for the system response time to lock on to the alarm.

FUNCTION TEST A control function which simulates a full "All Alarms On" condition.

GROUPING In every alarm system it is necessary to have some grouping of functions. Grouping can be control switch groups, output groups or first up groups.

<^^

GROUP INHIBIT A GROUP INHIBIT is a control switch function which, if operated, will inhibit the operation of any alarms in the inhibit group. Removal of the inhibit will allow the alarms to operate at the start of their sequence.

First up alarms will NOT be discriminated ifthey come up during inhibit.

GROUP LAMP OR GROUP REPEATANNUNCIATOR is a group output with an annunciator sequence as follows: Any alarm in the group will cause the group repeat annunciator to flash with the individual alarm annunciator, both group repeat annunciator and the individual annunciator go steady on accept. The group repeat annunciator will reflash on receipt of any other alarm in the group coming up. The group repeat annunciator will go off when all the alarms in the group are cleared and reset.

GROUP LAMP TEST A control switch function which checks the group annunciators and associated logic. It can be a separate input or assigned to the same input as the Main Lamp Test Switch..

GROUP RELAY A group relay is a relay driven from a grouped output. The group relay can have the following sequences:

CONDITION

1 Relayenergise on 2 Relay de-energise on 3 Relay energise on 4 Relay de-energise on 5 Relayenergise on 6 Relay de-energise on

Alarm on Alarm on Alarm on Alarm on Alarm on Alarm on

CODE

CS CF AS AF RS RF

(CLEAR-STANDARD) (CLEAR-FAILSAFE) (ACCEPT-STANDARD) (ACCEPT-FAILSAFE) (RESET-STANDARD) (RESET-FAILSAFE)

GROUP REFLASH RELAY A group relay which is normally energised (failsafe). It de-energises an occurrence of

first alarm in group, then gives a 300mS pulse on occurrence of each subsequent alarm. Re-energises when all alarms in group are cleared and reset.

HORN See Audible, UrgentAudible and Non-urgent Audible.

HORN CANCEL (or SILENCE) is a control switch function which mutes the audible without interfering with the

indicator sequences. (Also referred to as SILENCE)

INDICATORS (or ANNUNCIATORS) (sometimes referred to as lamps, screens, fascia, window) are the visual

displays which operate in the sequence specified.

INDIVIDUAL RELAY An individual relay giving an auxiliary relay output. The relay can have the same sequences

as the group relay (see GROUP RELAY).

INDIVIDUAL REPEAT An INDIVIDUAL REPEAT ANNUNCIATOR is an additional indicator (wired in parallel) to the main annunciator to give identical remote indication of the main annunciator.

INHIBIT An alarm can be inhibited either individually or in groups. Inhibiting an alarm prevents it from operating any outputs, be it individual (annunciator) or group (hom, group repeat annunciators, group relays).

INPUTS The system has three types of input: a mandatory 'POWER MONITOR' input (wired to an "INPUT COMMON" Terminal), ALARM INPUTS and CONTROL INPUTS. The standard alarm inputs (digital) are from volt free normally open or normally closed contacts, and Control inputs are from normally open contacts. Alarm inputs can be ANALOGUE wired into the appropriate Analogue Input Card.

INTERMITTENT FLASH FIRST UP SEQUENCE A first up discrimination sequence which indicates a first up alarm by means of an intermittent fast flash indicator. (See Sequence table M13) KEYSWITCH MODULE See Editable System.

LAMP TEST This is a control switch function which checks the annunciators and the associated logic.

LOCKING Locking is an alarm MODE which allows the alarm system to LOCK ON TO A MOMENTARY FAULT provided its duration is within the input response time parameters - see RESPONSE TIME.

LOGIC BOX The logic box is the sub-rack (crate) which contains the system logic and regulator.

MANUAL RESET - See RESET.

NON-LOCKING Non-locking is an alarm MODE which ensures the alarm system will NOT LOCK ON TO A MOMENTARY FAULT.

j0Hl

NORMALLY CLOSED Field contacts or relay contacts which are normally closed in the healthy state and open on

f'

alarm.

NORMALLY OPEN Field contacts or relay contacts which are normally open in the healthy state and closed on alarm.

NON-URGENT AUDIBLE Audible which operates on selected alarms which are specified as non-urgent - See URGENT AUDIBLE.

OUTPUTS This system has six standard outputs: Individual annunciator

Individual relays First up indicator Audibles

Group repeat annunciators Group relays

POINT Used in software to identify an alarm way - See 'WAYS'.

J0^L

POWER MONITOR An input from the "INPUT COMMON" supply. protection procedure within the system.

Loss of this input initiates a power break

POWER SUPPLY UNIT External supply unit to feed the alarm system.

PROGRAMMING The three PROGRAMMING functions referred to in the system are: 1 The EPROM firmware programming which customises the system.

2 The 8 way DIL switch on the I/O CARD used to set normally open or closed alarm input contacts.

3 I/O board address switches programmed to suit the program in#1.

RECALL Sometimes referred to as REFLASH. An alarm sequence which causes the annunciator to flash and the audible to sound afteraccept ifthe alarm clears and re-occurs, prior to reset. (Manual reset alarms only).

REGULATOR The integral voltage REGULATOR, in the LOGIC BOX which provides the +V "INPUT COMMON" field contact wetting voltage and the system logic 5V supply.

RELAY MODE AND TYPES Relays can be defined as FAIL SAFE (normally energised) or STANDARD (normally de-energised); individual orgroup; reed; power orsolid state.

REPEAT(ER)S Repeat(er)s refer to indicators orannunciators only (i.e., not relays) and can be either individual or group.

RESET Reset is a control switch function which is used in manual reset systems, which causes the annunciator of

an accepted and cleared alarm to return to normal. In Automatic Reset systems the annunciator of an accepted alarm will return to normal automatically when the alarm condition clears.

RESPONSE TIME Momentary alarms must be present for at least 16mSEC for the alarm system to respond.

SEQUENCES Annunciators, audibles and relays have different sequences to operate. The sequences referred to in the manual and in ROCHESTER INSTRUMENTS sequence tables detail the standard variations possible.

SILENCE See Horn Cancel.

SINGLE FLASH FIRST UP This isa standard first up discrimination using one (fast) flash rate for FIRST UP alarm and steady indication for subsequent alarms (See sequence tables M5 and M6).clears.

SLOW FLASH ON CLEAR An alarm sequence which causes the annunciator to slow flash when an accepted alarm clears.

STANDARD RELAY Normally de-energised in the non-alarm state as opposed to a failsafe relay.

TRIP POINT Presetvalue(s) at which analogue inputs will cause alarm(s) to be initiated e.g., LO-LO, LO, HI, HI-HI.

URGENT AUDIBLE Audible which operates on selected alarms which are specified as urgent - See NON-URGENT AUDIBLE.

WAYS An alarm input to the system and its associated outputs.

WINDOW Asingle indicator or annunciator within a display.

2ENER BARRIER An intrinsically safe input device for use in hazardous areas.
