NON-ZERO-CROSSING THYRISTOR TRIGGERS TWO-THYRISTOR TRIGGER APTT 841M • Mains voltage up to 660Vac (minimum 3Vac) • Control voltage 12Vcc (10mA) • Supply voltage 12Vcc (250mA) • Galvanic isolation 4.000V • Operating temperature -20/+50ºC • Triggers the full range of SEMIKRON thyristors • Control signal indicator LED

This module has been developed to trigger two thyristors antiparallel-connected or rectifying (B2HK or B2HKF) thyristors. It is advisable to use a RC network in the thyristors. Designed as a single-phase static relay in load connects and disconnects in when in c.c. and a.c. applications. The load connects when the control voltage is output and disconnects when the thyristors’ current crosses the zero. This module requires an external +12Vcc – 250mA power supply. The thyristors can be triggered by joining two terminals (+12Vcc and “trigger”) or using an outside 12 Vcc voltage supply connected between 0V and “trigger”.


THYRISTOR TRIGGER MODULES RT380M B2C PHASE ANGLE THYRISTOR REGULATOR - 230ac or 400Vac supply - Perfect operation with inductive loads - Control voltage selectable 0-5/0-10 V. - Auxiliary 5V supply for the control voltage - 4.000 V galvanic insulation - Triggers the whole range of SEMIKRON thyristors - No external components required. - Works with 50 Hz and 60 Hz The model RT380MU B2C is designed to trigger 4 thyristors in B2C configuration, and can also be used with only 2 thyristors, with a variable delay over the zero crossing of the mains alternating voltage. In this way, the power allowed through to the load by the thyristors is regulated. The load may be supplied with a variable alternating voltage if both thyristors are connected in antiparallel, or with a variable DC-Voltage if both are connected in a controlled- or semi-controlled rectifier assembly. The triggering signal could be a 0-5 V or 0-10 V from a external DC power supply. The user can also use a 10 kOhm potentiometer connected between 5Vout, 0 V and 5 V in pins. This regulator is suitable for a wide range of possible applications, among which are: Illumination control, electric ovens temperature control, d.c. motor speed control, starting and control of induction motor speeds, galvanising bath control, electrolytic process control.

The module is equipped with pulse transformers, and has been designed to trigger 6 thyristors in W3C anti-parallel connection. It is useful that the thyristors are equipped with RC circuits. The module is most appropriate for applications as a three-phase static relay for load switching in AC operation. Switching on is performed after the control voltage is applied, waiting when the thyristor current crosses zero. The thyristors are triggered by connecting the J1(+12V) and J2(+trigger), on the one hand, and J3 (trigger) and J4(ground) terminals, on the other. This can also be accomplished by using an external voltage of 6 to 30 VDC connected between J2(+) and J3(-). To supply other devices (max. 50 mA) the internal auxiliary voltage of 12 VDC(J1: +12V, J4:0V) can be used. By providing a step-down transformer at the power input terminals, the thyristors can be triggered from a line voltage up to 690 VAC, since the pulse transformers whithstand this voltage. In this case, some little changes on the module have to be done (change of the resistors R43, R44, R45). for 330kΩ (or two of 150kΩ) 3W minimum).Those rsistors are calculated to for a W3C connection in series with the phases. In case to connect the antiparallel thyristors in series with the load, and both (thyristors + load) in triangle, resistors have to been changed or they can be damaged.

This module has been designed for triggering 6 thyristors with phase regulation in order to control the power on the load. It is recommended the use of external RC-snubbers to protect the thyristors and to facilitate its triggering. The load may be supplied with a variable alternating voltage if the 6 thyristors are connected in antiparallel W3C, or with a variable direct voltage if they are connected in B6C, B6HK or B6HKF. The external thermal trip has to be normally close. If it opens, the module stops, the green LED stops lighting and the red LED lights. The module has an automatic Power-on delay of approx. 1 second. That means that during the first second the output is inhibited (no pulse output). It is important to connect the three phases and the outputs of gates and cathodes exactly as shown in the label. Done this, the input phases of the whole equipment (module + power) can be connected in the sequence you want. To select the thyristors connection W3C, the three minidips have to be in W3C position. For a B6C connection, they have to be in B6C position. An input of +12V (7 to 16V) in the input INHIBIT stops the output of gate pulses and red LED starts lighting. This +12V can be external or using the internal auxiliary 12VDC present at the thermal trip jumper (see drawing).

START_STOP Allows the device to stop and start from the exterior when the device is in AUTOMATIC (see Parameters) mode and in LOCAL mode. At high level it is commanded to start and at low level it is commanded to stop. POT_KEY Input for selecting how the reference value is entered (see USER_DELAY, B6C or W3C Configuration). If input is at high level the device is instructed that the reference value is entered through the display board keyboard in local mode and through communications in remote mode (see LOCAL mode and REMOTE mode). If at low level, the device is instructed that the reference value must be entered through the IN_0_5 or IN_0_10 input. When the device is configured as a STARTER (see Supported configurations and frequency), this input is used for deactivating the ENERGY_SAVING mode (see STARTER Configuration). When entry is at high level, the ENERGY_SAVING mode will be deactivated in case this mode was activated. CON_IN_TEMPE Ohm input for the temperature sensor. This input is used to measure the temperature of where the sensor is located within the device. It allows readings from 0 to 150 ยบC. IN_0_5 Input of external reference value. 0 volts corresponds to a reference value of 0.0% and 5 volts corresponds to a reference value of 100.0%. With a shunt of 250 Ohms, the reference value can be entered through a 0-20 mA current loop. By deactivating J3 (see) and replacing the R9 and R10 value (100K-1%) with 80K6-1%, a 4-20 mA current loop can be used. IN_0_10 Input of external reference value. 0 volt corresponds to a reference value of 0.0% and 10 volts corresponds to a reference value of 100.0%. With a shunt of 500 Ohms, the reference value can be entered through a 0-20 mA current loop. By deactivating J3 (seePhysical Description) and replacing the value of R9 and R10 (100K-1%) with 80K6-1%, a 4-20 mA current loop can be used. INT1+/INT1Differential voltage input for measuring current. This input allows for the measuring of the average rectified current circulating through the bridge being regulated. Through J4 a floating measure may be done (open J4), or with respect to the ground (closed J4 unites INT1- to the device ground). This input may be used by connecting the output of a current transformer to its respective shunt or connecting this input in parallel to a shunt through which the current to be measured is circulating. Input ranges may be adjusted with the values in R4, R5, R6 and R8. Default values (6K65-1%, 10K-1%, 47K-1% and 47K-1% respectively) are adjusted to show 100.0% of current with an average voltage input of 5.4 v at 50 Hz. The sequence to follow for adjusting these values is: 1. Establish the value of the impedance variables of the input (Rin Ohms), working frequency (F Hz) and the average voltage value corresponding to 100.0% (V v). 2. Set the value of R4 to less than 10 KOhms and less than Rin. 13


3. R5 = Rin − R 4 F × 2026 × Rin 4. R8 = R 6 = V × R4 5. Check that the value of R8 and R6 is not higher than 200 KOhms. If values are higher, repeat the sequence with a higher value of R4 or a lower Rin value. 164500 × (R5 + R 4) 6. The instantaneous voltage input value must be lower than . If R8 × R 4 it is not lower, the sequence must be repeated with a higher V. That is, the device will measure less than 100.0% of current when the original V voltage is applied.

All resistances used must have a tolerance of 1%. VOLT:

Voltage input. This input allows for the measurement of the average rectified voltage that is applied to the bridge being regulated. This input may be used by connecting the output of a transformer, or connecting this input in parallel to the voltage that is being measured. Input ranges may be adjusted with the values of R1, R2, R3 and R11. Default values (47K-1%, 10K-1%, 16K5-1% and 47K-1% respectively) are adjusted to show 100.0% of voltage with an input of 5.4 v of average voltage. The sequence to follow in order to adjust these values is as follows: 1. Establish the value of the impedance variables of the input (Rin Ohms) and average voltage value corresponding to 100.0% (V v). 2. Set the value of R2 to less than 10 KOhms and less than Rin. 3. R3 = Rin − R 2 95784 × Rin 4. R1 = R11 = V × R2 5. Check that the value of R1 and R11 is not higher than 200 KOhms. If values are higher, then the sequence must be repeated with a greater R2 value or a lower Rin value. 164500 × (R3 + R 2) . If it is 6. The instantaneous voltage input must be lower than R1 × R 2 not lower, the sequence must be repeated with a higher V. That is, the device will measure less than 100.0% when the original V voltage is applied. All resistances used must have a tolerance of 1%. L1/L2/COM: Double current input with an internal shunt. This input allows for the measurement of the average rectified current circulating through the bridge being regulated.

This input may be used by connecting one or two current transformers. If only one current transformer (L1/COM) is connected, the current can be measured through one of the phases of the rectifying bridge. If a second transformer (L2/COM) is connected which was derived from another phase, the total circulating current can be measured. The input ranges can be adjusted with the internal shunt value R7. The default value (475 Ohms) is adjusted to show 100.0% of current with an input of 11.3 mA (IL1 + IL2) of average current at 50 Hz. The sequence to follow in order to adjust this value is as follows: 14


1. Set the value of the working frequency variables (F Hz) and the value of the total average current corresponding to 100.0% (I A). F 2. R7 = I Ă— 9.262 3. Check that the R7 value is not higher than 1 KOhm. If the value is higher, repeat the sequence with a higher I value; that is, increase the I.output/I.input ratio of the applied current transformers. 4. The value of the instantaneous input of the current (IL1 + IL2) must be lower 8.5 than . If it is not lower, the sequence must be repeated with a greater I. That R7 is, the device will measure less than 100.0% of current when the original I current is applied. The resistance used must have a tolerance of 1%.

15


Current inputs As described in the section above, the device features two current inputs: INT1+/INT1- and L1/L2/COM. Only one of them may be used. Through the parameter INPUT_INTENSITY (see Parameters) the device is instructed about the input that has been connected. If the value is set to R_INT_DIF, it shows that INT1+/INT1 has been connected. By contrast, if the value is set to R_INT, it shows that L1/L2/COM has been connected.

LOCAL mode and REMOTE mode The device can be governed from the display board in LOCAL mode. In REMOTE mode, the device can be governed from a Host via an RS-485 communication (see Communications). Switch to REMOTE mode To switch to remote mode, the LOCAL_REMOTE parameter must be set to the REMOTE value (see Parameters). Switch to LOCAL mode To switch to local mode, one of the following operations must be done: 1. The LOCAL_REMOTE parameter must be set to the LOCAL value through communications (see Communications). 2. Loading the default parameters (see Parameters). Working in LOCAL mode In local mode the device does not accept commands or parameter changes coming through its communications port. However, the device does respond to data requests through communications. Because of this, the device cannot be governed remotely but its variables may be monitored in the remote Host.

In LOCAL mode, the display board is operational for managing the dialogue, showing displays and governing the device. Working in REMOTE mode In remote mode, the display board is left inhibited and shows the following message:

Where 1 represents the communications address. In remote mode, the device is governed solely through communications; therefore, the device cannot be set to AUTOMATIC mode (see Operating statuses).

16


Operating statuses The device will always be in one of the following operating statuses, regardless of its set configuration: STOPPED The device is stopped. No pulses are applied to the thyristors. The display shows:

To start the device the following operation must be performed based on the value of the AUTO_MANUAL parameter: AUTO_MANUAL = AUTO Automatic operation. To start the device, activate the START_STOP input. AUTO_MANUAL = MANUAL Manual operation. To start the device, the INC and INTRO keys must be pressed at the same time if the device is in LOCAL mode. If the device is in REMOTE mode, you must send a STOP_START writing (see Communications).

When the device starts operating, it switches to PEAK status. PEAK

The device is running. Pulses are applied to the thyristors. The display shows: Where 100.0 blinks and represents the working point (see STARTER Configuration and USER_DELAY, B6C or W3C Configuration) that has been set as the PEAK. This working point is applied every time the regulation is started. The length of this status depends on the TIME_PEAK parameter. To switch to STOPPED mode the following operation must be performed based on the value of the AUTO_MANUAL parameter: AUTO_MANUAL = AUTO Automatic operation. To stop the device the START_STOP input must be deactivated. AUTO_MANUAL = MANUAL Manual operation. To stop the device the CURSOR and INTRO keys must be pressed at the same time if the device is in LOCAL mode. If the device is in REMOTE mode, a STOP_START writing must be sent (see Communications).

When this status finishes, the device switches to RAMP UP status. RAMP UP The device is running; pulses are applied to the thyristors. The display shows: Where 100.0 is blinking and is the working point that is being applied. This working point

will vary linearly from the PEDESTAL value up to the working reference value set during a 17


period of time equal to RAMP_UP. If the current limitation is activated, through the LIM_INTENSITY parameter (see Parameters), the working point is not increased any more if the measured current exceeds the value of the MAX_INTENSITY parameter. To switch to STOPPED mode the following operation must be performed based on the value of the AUTO_MANUAL parameter: AUTO_MANUAL = AUTO Automatic operation. To stop the device the START_STOP input must be deactivated. AUTO_MANUAL = MANUAL Manual operation. To stop the device the CURSOR and INTRO keys must be pressed at the same time if the device is in LOCAL mode. If the device is in REMOTE mode, a STOP_START writing must be sent (see Communications).

When this status finishes, the device switches to RUNNING status. When the device is stopped through one of the two methods above, the device switches to RAMP DOWN status before reaching the STOPPED status. RUNNING The device is running; pulses are applied to the thyristors. The working point is equal to the set reference value (see STARTER Configuration and USER_DELAY, B6C or W3C Configuration). The display shows: Where 100.0 is the working point that is being applied.

Where 100.0 indicates the voltage in % as measured in the VOLT input. This indication is not displayed if the device is configured as a starter (see Supported configurations and frequency). Where 100.0 indicates the current in % as measured in the INT1+/INT1- or L1/L2/COM input depending on the INPUT_INTENSITY parameter. Where 100 indicates the temperature in ยบC as measured in the CON_IN_TEMPE input. To switch back and forth between the displays above press the INC or CURSOR key. To switch to STOPPED mode one of the following operations must be performed based on the value of the AUTO_MANUAL parameter: AUTO_MANUAL = AUTO Automatic operation. To stop the device the START_STOP input must be deactivated.

18


AUTO_MANUAL = MANUAL Manual operation. To stop the device the CURSOR and INTRO keys must be pressed at the same time if the device is in LOCAL mode. If the device is in REMOTE mode, a STOP_START writing must be sent (see Communications).

When the device is stopped using one of the two methods above, the device switches to RAMP DOWN status before reaching the STOPPED status. RAMP DOWN The device is running; pulses are applied to the thyristors. The display shows:

Where 100.0 blinks and is the working point that is being applied. This working point will vary linearly from the value when the stop was commanded until the PEDESTAL value during a period of time equal to RAMP_DOWN. To switch to RUNNING mode one of the following operations must be performed based on the value of the AUTO_MANUAL parameter: AUTO_MANUAL = AUTO Automatic operation. To start the device the START_STOP input must be activated. AUTO_MANUAL = MANUAL Manual operation. To start the device the INC and INTRO keys must be pressed at the same time if the device is in LOCAL mode. If the device is in REMOTE mode, a STOP_START writing must be sent (see Communications).

When this status is complete, the device switches to STOPPED status. ALARM This status is identical to the STOPPED status. The only difference is that the stop has been provoked by an alarm (see Alarms). The potential display messages are:

All of the display is blinking. Where 01 is the alarm number that has been activated (see Alarms). All of the display is blinking. Where 100 is the temperature measured in the CON_IN_TEMPE input. It shows that the OVER HOT alarm has been activated. To switch to STOPPED mode from any of these two types of alarm one of the following operations must be performed based on the value of the AUTO_MANUAL parameter: AUTO_MANUAL = AUTO Automatic operation. To stop the device the START_STOP input must be deactivated.

19


AUTO_MANUAL = MANUAL Manual operation. To stop the device the CURSOR and INTRO keys must be pressed at the same time if the device is in LOCAL mode. If the device is in REMOTE mode, a STOP_START writing must be sent (see Communications).

All of the display is blinking. It indicates that the OVER_CURRENT alarm has been activated. To exit this status a reset must be applied (see Start and Reset). All of the display is blinking. It indicates a SCR_FAILURE alarm. Where 1 shows the thyristor that has failed. To exit this status a reset must be applied (see Start and Reset).

20


STARTER Configuration In this operating mode, you can control the start and stop of an asynchronous motor. The regulation is direct. The percentage value that we see as the working point (see Operating statuses) is the percentage value of the conduction angle. By programming the appropriate levels of PEAK, TIME_PEAK, PEDESTAL, RAMP_UP and RAMP_DOWN, soft-starter ramps, stop ramps and initial start peaks can be generated (see Operating statuses). If a current input is connected, the current circulating in the motor can be monitored and limited. Current limitation If the current limitation is activated through the LIM_INTENSITY parameter (see Parameters) and the average current exceeds the value of the MAX_INTENSITY parameter for 25 seconds, the OVER CURRENT alarm will be activated (see Alarms). Energy saving This mode is activated by setting the ENERGY_SAVING parameter to a YES value. When this mode is active the device regulates the working point based on the load of the motor. The same speed is thus achieved with less power dissipation. To perform this regulation, the device measures the phase difference, at the time of starting the motor, between the thyristors voltage and the line voltage. Then, while running, the device diminishes the working point for as long as the present phase difference is higher than the start phase difference.

When the energy saving mode is activated, it can be deactivated externally through the POT_KEY input. If energy saving was activated and this input is set at high level, the energy saving is deactivated.

21


USER_DELAY, B6C or W3C Configuration In this operating mode, the device regulates, through the firing angle of the thyristors, the voltage in the load. There are four types of regulation that can be chosen through the MODE_REGULATOR parameter: DIRECT, VOLTAGE, INTENSITY, SERIES. Described below are several concepts used in this operating mode. Reference value In any of the regulating modes we will always use the reference value variable. This variable is represented by the REFERENCE VALUE parameter (see Parameters). The reference value is the value of the variable to be regulated that the user wishes to obtain in the load. The variable to be regulated depends on the regulation type. In fact, the device regulates with respect to the working point. The working point derives directly from the reference value and is equal to the latter except when the ramp up, peaks and ramp down statuses are occurring or the device is indicating an alarm (see Operating statuses and Alarms). Both the reference value and the working point are expressed in % to one decimal. Reference value modification Described below are the different existing ways to modify the reference value: MODIFICATION FROM THE OUTSIDE The reference value may be an image of the IN_0_5 or IN_0_10 input (see Inputs). To this effect, the POT_KEY input must be at low level. MODIFICATION BY KEYBOARD If the POT_KEY input is at high level and the device is in LOCAL mode (see LOCAL mode and REMOTE mode), the reference value is modified from the keyboard of the display board. The procedure to change the reference value is as follows: 1. Start the device and wait for it to enter into RUNNING status (see Operating statuses). 2. Select the working point display by pressing the INC or the CURSOR key. 3. Press the INTRO key. The display will show, blinking:

Where 100.0 is the current reference value. 4. Each short push of the INC key increases the reference value by 0.1%. If you press and hold the INC key for more than two seconds the reference value is increased more rapidly. Each short push of the CURSOR key decreases the reference value by 0.1%. If you press and hold the CURSOR key for more than two seconds the reference value decreases more rapidly. 5. When the desired reference value has been obtained, press INTRO to validate the change and return to the working point display. MODIFICATION THROUGH COMMUNICATIONS If the POT_KEY input is at high level and the device is in REMOTE mode (see LOCAL mode and REMOTE mode), the reference value is modified through Communications (see Communications). If the POT_KEY input is at low level, modifications to the reference value done in this way are to no effect. MODIFICATION IN STOPPED STATUS If the POT_KEY input is at high level and the device is in LOCAL mode (see LOCAL mode and REMOTE mode), the reference value may be modified like any other parameter

22


provided that the device is in STOPPED status (see Parameters). If the POT_KEY input is at low level, modifications to the reference value done in this way are to no effect. Linearization When the device operates in B6C or W3C mode, it is possible to instruct the device to linearize the output. To linearize the output means that the output percentage does not indicate the conduction angle but the efficient voltage applied to the load through the converter (B6C) or the regulator (W3C) that is being governed. To activate this option the LINEAR parameter must be set to a YES value. When the linearization is deactivated, the device applies a firing angle equal to the one shown by the regulation output. When linearization is activated, the device applies a firing angle which produces an efficient voltage percentage in the load as shown by the regulation output. PID

For VOLTAGE, INTENSITY or SERIES regulations, the device features two internal PID’s. One PID regulates VOLTAGE and another one regulates INTENSITY. In SERIES regulation, both are used. The PID parameters for VOLTAGE are as follows (see Parameters): KP_VOLTAGE: Proportional constant. TI_VOLTAGE: Integral time. TD_VOLTAGE: Derivative time. And the PID for intensity is the following: KP_VOLTAGE: Proportional constant. TI_VOLTAGE: Integral time. TD_VOLTAGE: Derivative time. The integral and derivative parts can be made null by setting a value of 0 to their respective constants. The variable used by the voltage PID is the VOLT input. The variable used by the intensity PID may be either INT1+/INT1- or L1/L2/COM. The cycling or sampling time of the variable is equal to the period of the network voltage that is applied to the converter or controller. Thus, for a network frequency of 50Hz the sampling time is 20 msec., and for a network frequency of 400 Hz it is 2.5 msec. The PID outputs are limited to 0.0% at the bottom and 100.0% at the top, blocking integration in case the calculation falls outside this interval. DIRECT mode regulation In this regulation mode, the working point is set directly at output. If linearization is activated (see Linearization), the percentage of efficient voltage in the load is equal to the percentage shown in the working point. If linearization is deactivated, a conduction angle is applied which is equal to the percentage shown by the working point. W ORKING POINT

VOLTAGE LIMITATION If the voltage limitation is activated through the LIM_VOLTAGE parameter (see Parameters), the device attempts to prevent its VOLT input value from being higher than the value of the MAX_VOLTAGE parameter, giving priority to this condition rather than to the working point value. To that effect it uses the internal voltage PID and its constants must be adjusted. INTENSITY LIMITATION If the intensity limitation is activated through the LIM_INTENSITY parameter (see Parameters), the device attempts to prevent its input INT1+/INT1- or L1/L2/COM value from being higher than the value of the MAX_INTENSITY parameter, giving priority to this condition rather than to the working point value. To that effect it uses the internal intensity PID and its constants must be adjusted. VOLTAGE mode regulation When regulated in VOLTAGE mode, the device uses the voltage PID to regulate the output and to cause the value in % of its VOLT input to be equal to the value in % of the working point. If linearization is activated (see Linearization), the efficient voltage percentage in the load is equal to the percentage shown in the output. If linearization is deactivated, a conduction angle equal to the percentage shown by the output is applied.

Alarms The MP410 has a total of six potential alarms. All of them are described below in order of priority. In case more than one alarm is activated at the same time, the device will perform based on the alarm with the highest priority. SCR FAILURE This alarm is activated when the device detects that some of the thyristors cannot be burst triggered. In order for the device to be able to detect this failure, it requires a minimum of applied output, which depends on the configuration of the bridge (see Supported configurations and frequency) and the network frequency. In order to deactivate the alarm a reset must be applied (see Start and Reset). The device comes to a total stop when this alarm is activated, that is, it does not go through the RAMP DOWN status. This alarm can be prohibited through the AL_FAILURE_THYRISTORS parameter. If the value is set to YES, the alarm is permitted. If the value is set to NO, the alarm is prohibited. Every time a thyristor must be burst triggered because the device detects that it is disconnected and must switch to conduction, a burst is applied with the number of pulses indicated by the BURST parameter. Once the thyristor has been burst triggered, no further burst is applied unless the thyristor is current-free. This represents important energy savings in the burst firing of the thyristors. Depending on the application and the working frequency more or fewer burst pulses will be required. Further, the value of the BURST parameter also indicates how many pulses must be applied to a thyristor before signaling SCR FAILURE in case the thyristor is not successfully burst triggered. INHIBIT INPUT Alarm number 1. This alarm is activated when the INHI_IN input is activated. To deactivate this alarm, this input must be deactivated. The device comes to a full stop when this alarm is activated, that is, it does not go through RAMP DOWN status. This alarm is always permitted. THERMOSTAT Alarm number 2. This alarm is activated when the THERMO input is activated. To deactivate this alarm this input must be deactivated. The device comes to a full stop when this alarm is activated, that is, it does not go through RAMP DOWN status. This alarm is always permitted. PHASE FAILURE Alarm number 3. This alarm is activated when the device detects that more than one phase is failing. To deactivate the alarm you must recover the phases. This alarm is not always displayed. The device comes to a full stop when this alarm is activated if the AL_FAILURE_PHASE parameter is set to a YES value. If the parameter is set to a NO value, the alarm is only displayed but the device does not stop. OVER HOT This alarm is activated when the temperature measured in the CON_IN_TEMPE input exceeds the value of the CON_TEMPERATURE parameter. To deactivate this alarm the measured temperature must be lower than the value of the CON_TEMPERATURE parameter less a hysteresis of 10 ยบC. The device normally stops when this alarm is activated, that is, it goes through the RAMP DOWN status. This alarm may be prohibited through the AL_TEMPERATURE parameter. If you set the value to YES, the alarm is permitted. If you set the value to NO, it is prohibited.

27


OVER CURRENT Alarm number 5. It only works when the device is configured as a STARTER (see Supported configurations and frequency). This alarm is activated when the measured current exceeds the value of the MAX_INTENSITY parameter for 25 continuous seconds. To deactivate the alarm you must apply a reset (see Start and Reset). The device normally stops when this alarm is activated, that is, it goes through the RAMP DOWN status. This alarm may be prohibited through the LIM_INTENSITY parameter. If you set the value to YES, the alarm is permitted. If you set the value to NO, it is prohibited. Parameters NUMBER

Parameter modification Below is a description of the different procedures available to modify the device parameters: MODIFICATION BY KEYBOARD If the device is in LOCAL mode (see LOCAL mode and REMOTE mode), parameters are modified using the keyboard in the display board. Modification of parameters is password protected. The procedure to change the value of the parameters is as follows: 1. Stop the device and wait for it to enter into STOPPED status (see Operating statuses). Once in this status, press the INTRO key for three seconds. 2. The display will show, with the last digit blinking:

Where 0000 must be written with the password value: By pressing the CURSOR key you change the digit to be modified, indicated by blinking. Short pushes of the INC key increase the value of the blinking digit. If you press and hold the INC key for more than two seconds the value of the blinking digit is increased more quickly. When the digit reaches the value 9, if you press INC it returns to value 0. 3. Once you have keyed in the right password value, press INTRO to go on to step 4. If you press INTRO and the password value is wrong you return to step 2. The third time that you press INTRO with a wrong password value it leads to the blocking of the device showing the following in its display: 4. The display shows, one by one, the parameters and their values. To switch back and forth from parameters you must press the INTRO key. Parameters that are not used based on the programming that has been done with the previous ones do not appear. When the last parameter is programmed, the device returns to STOPPED status. Modification of the value for each parameter is done by pressing the CURSOR key to select the digit to be changed and pressing the INC key until you get the desired digit value. MODIFICATION THROUGH COMMUNICATIONS If the device is in REMOTE mode (see LOCAL mode and REMOTE mode), the parameters can only be modified through Communications (see Communications). Loading default parameters If you press the B2 key (see Physical description) for 5 seconds, the device loads the default values into the parameters.

The size of the read-only data is 2 bytes (word). Read and write data Read and write data, as expressed by its name, can be read and written through communications if the device is in REMOTE mode. If the device is in LOCAL mode, they can only be read. The set of read and write data is made up by the parameters, whose data address is equal to the parameter number, plus the STOP_START data, whose data address is 31. By writing the STOP_START data you can command the starting or stopping of the device remotely. If the value of the data is 0, stop is commanded; if the value of the data is 1, start is commanded.

30


Parameters whose values have decimals are communicated as integers that are equal to the value multiplied by 10n, where n is the number of decimals. The size of the read and write data is 2 bytes (word). Protocol All values are sent in hexadecimal format coded in ASCII. For instance: to send the value 956, first it is formatted into hexadecimal (0x03BC) and the characters ‘0’ ‘3’ ‘B’ and ‘C’ are sent. Thus, for 1 byte values 2 bytes need to be sent and for 1 word values 4 bytes need to be sent. The communications address of each device is the ADDRESS parameter. Although the ADDRESS parameter is one word, the address field in the frame is 2 bytes, only codifying the byte under the parameter. No more than 31 devices can be in the bus and all devices present in the bus must have different communications addresses.
