PRINCIPLE OF OPERATION

INSTALLATION AND START-UP

The Series 5000 Temperature Control is actuated by

Upon receiving the Series 5000 Temperature Control, inspect the unit to verify it has not been damaged during

differential expansion of dissimilar metals in the temperature sensing element. The forces and motion resulting from this

differential expansion actuates either a force balance nonbleeding pneumatic pilot or an electric pilot. The control mode can be either direct acting (increasing temperature increases output) or indirect acting (increasing temperature decreases output. The temperature sensing element is made of 1/8 inch stainless steel pipe which permits the control to

be used to a maximum pressure of 3000 PSI through a

shipment. The unit may be assembled in either a direct or indirect acting mode. It also may be furnished with a

pneumatic or electric pilot and with a variety of probe lengths. Check the nameplate information to establish that the unit is correct for the intended application. The Series 5000 Temperature Control is factory assembled, tested and ready for use as shipped and requires no pre-adjustments before installation.

outer metal tube expands and contracts in proportion to change in temperature. The disimilar inner metal, connected to the outer tube at one end, is pulled along with temperature increase and is pushed back with temperature decrease.

Motion of inner metal moves a lever bar. The lever bar moves the pneumatic pilot thrust pin or the plunger of an electrical switch.

Installation is achieved by threading the tapered pipe threads on the probe body into the process connection.

When a The supply and output connections for the pneumatic pilot separable socket is used, install the socket into the process connection first and then follow with the installation of the temperature control.are 0.25 inch NPT. The supply connection is located on top of the pilot via a street elbow

and the output connection is directly behind the 0-30 PSI output gage.

The electric pilot is provided with a 0.50 inch NPT connection on the switch housing. To gain access to the switch terminals, remove the front cover of the switch housing. Lift up the insulator flap to expose the terminals.

The flap is conveniently marked with the identity of each terminal designating common lug, normally open and

normally closed. To wire the control for a direct acting mode (increasing temperature actuates the switch), use the normally open terminal. For the indirect acting mode, use the normally closed terminal.

NOTE: The Series 5000 Temperature Control with electric pilot is assembled in the indirect mode only to maximize the switch operation. The output mode is established by the appropriate switch wiring only.

Once the piping or wiring of the unit is complete, the process media temperature and pressure may be raised.

With the system now under heat and

Begin calibration by turning the range adjusting screw until the pressure shown by the output gage starts changing. For

direct acting mode, clockwise rotation of the adjusting screw, as viewed from directly above the control, will increase the temperature set point. Wait for the output pressure to stop changing or reverse the direction of the adjusting screw until a reversal in output pressure is reached.

A reversal in the output signal means that the fluid around the probe is near the temperature for which the control is set.

The temperature probe of the control has a faster response to

the temperature change than the reference thermometer.

Avoid turning the adjusting screw when the pilot output pressure is changing rapidly. When the temperature is changing rapidly, as when a heater is initially started, the output pressure from the control may change the full scale while the reference thermometer reads considerably below the actual

MAINTENANCE

simple design, the Norriseal Series 5000 Temperature Control requires Because of its inherently

minimal routine maintenance. Visual external inspection of the unit is the only necessary maintenance required on a routine basis. If a performance problem occurs, refer to the troubleshooting section for the appropriate action. A guideline for maintenance practices is listed below.

1.

For pneumatic pilot, use clean, filtered and regulated supply air 15 to 30 psi. For electric pilot, always disconnect power supply before performing any maintenance. The switch rating

is 15 Amps, 460 VAC. 2. Operate unit within

the design limits as

described under "Specifications".

8.

Inspect unit periodically based on operating conditions.

4.

Replace seals with new parts whenever unit is disassembled.

Calibration is accomplished by the use of a reference thermometer placed at the temperature control point.

CAUTION: There is a small flat washer (Item 30) directly behind the street elbow which is loaded by the peanut spring (Item 20).

Exercise care when removing the street elbow so as not to lose the washer. With the elbow and washer removed, the peanut (Item 19) and peanut spring may be removed from the valve block nspect the interior of the valve block and clean as needed with a mid solvent. Re-assemble unit in reverse order of the disassembty. Keep clean, do not apply grease to pilot parts NOTE: When replacing the moving seat/diaphragm assembly, the jam nut of the assembly must be facing upward in view as the diaphragm sits flat within the base. The small nib protruding from the lower portion of the moving seat assembly must engage its mating hole in the thrust pin (Item 21). Reconnect the piping to the plot and check its thrust pin (Item 21) Reconnect the piping to the pilot and check its operation by manually actuating the torque bar and observing the output.

For correct operation, only 1 to 3 inches of the probe end should be exposed to the pilot flame. The remainder of the probe should be positioned so as not to be heated directly by

the main burner flame.

Also, because pilot operation

depends on heat loss from the unheated portion of the probe, this portion must not be closely confined or insulated.

In hooking up the control, a pressure gauge must be installed to show the output pressure; proper adjustment of the device is not possible without it.

screw to the left beyond the mark originally made for pilot light operation, this means that the original mark is for an operating temperature that is too high. If it is left on the

original setting, the main burner fuel would be blocked while the pilot light still burned. For a safe setting, the screw must be turned to the left slightly past the setting necessary to keep the output pressure on control at the coolest part of the overall firing cycle.

To insure the shortest possible time lag between a pilot

Pilot supply pressure must not exceed 30 PSIG. Supply gas must be clean and free of foreign matter. After connecting pilot supply to the inlet, remove the cap (Item #1) and turn the adjusting screw (Item #3) until pressure shows on the

determined by the heater in operation.

After the hook up has been completed and pilot supply connected to the control, turn the adjusting screw slowly until the output pressure is a few pounds below the pilot supply pressure; the setting is now on the control point.

Light the pilot flame and the pressure on the output gauge

will almost immediately rise to the input pilot pressure.

Turn the adjusting screw slowly to the right until the output pressure drops a few pounds; the pressure will immediately start to rise again. By slowly turning the adjusting screw to the right, the element heats.

The output pressure may be "tracked" so as to keep the setting of the pilot exactly on the control or actuation point.

As the probe approaches the operating temperature, the rate of climb of the output pressure will slow. Heating of the probe from atmospheric temperature will take a few minutes.

In general, the longer the probe, the longer it will be required to establish the equilibrium temperature gradient.

After the probe has been heated to the point where there is not climb in output pressure for two or three minutes, mark the setting of the screw, open the main burner valve and let the heater operate under normal service conditions. Watch

the output pressure closely; opening of the main burner valve may bring in a rush of secondary air so as to cause the pilot flame to flow on and off of the probe and thus lower the probe temperature.
