The JC 5383A System Simulator and Calibration Kit is a portable, prepiped test panel to check out pneumatic controls. The kit also simulates a real system for field calibration of receiver-controllers and low-pressure controllers (within 0 to 15 psi). The air connections, pressure regulators, and gauges are numbered with lines drawn between them to show the internal circuitry of the panel. The panel is constructed so that the case can be hung by the handle on the wall next to the control panel for hookup convenience.

The JC 5383B Simulator is designed for installation into an existing JC 5383 (X-200-173) Calibration Kit to create a JC5383A System Simulator and Calibration Kit, as mentioned throughout this bulletin.

T-5800 Series Receiver-Controllers Initial Setup (for Checkout)

Figure 4: T-5800 Receiver-Controller Initial Setup

1. Furnish supply air (20 to 90 psig) to the “MAIN AIR IN” connection of the calibration kit.

2. Set regulator S-5 to furnish 20 psig as read on gauge G-5.

3. Using the “O/S/F” connector and tubing furnished with the kit, connect the supply line to the “Supply” fitting and connect the output line to fitting G-6. (The fan “F” line is not used.)

4. Using the “M/CV/SP” connector and tubing, connect the input lines to the gauge connections that match the ranges of the transmitters. Do not connect input “M” for single-input receiver-controllers. Vent the “SP” input for units with local set point.

5. Install the furnished rubber caps on all unused fittings on the calibration kit to prevent leakage.

6. Remove the Orifice jumper on the T-5800 (if connected) and cap these spigots with the black rubber caps provided with the T-5800 (see Figure 5).

7. Position the Action Side jumper and, if present, Set Point Readjustment Side jumper on the T-5800 for the proper action and readjustment per the job requirements.

8. For Proportional plus Integral (PI) models, disconnect the PI jumper from one of its spigots since the PI function, as well as the gain, can only be checked and adjusted during actual system operation (see Figure 5). Pulling the PI jumper off of one of its spigots causes the receiver-controller to operate as a proportional-only controller.

T-5800-1 and T-5800-2 Single-Input Receiver-Controllers (Calibration)

Set Point Adjustment

1. Select the proper gauge on the calibration kit to match the range of the Controlled Variable “CV” transmitter. Connect the gauge chosen to the “CV” spigot on the T-5800.

2. Determine the set point required and rotate the gradual switch (for the gauge chosen in Step 1) to this required value.

3. Adjust the set point (local or remote) until the output pressure of the T-5800 is at the mid-spring-range of the controlled device.

Gain Adjustment

Note: The Set Point Adjustment section must be completed before moving to these steps.

1. The T-5800 must be connected to the actual control system to adjust the gain. Remove the receiver-controller from the calibration kit and reconnect the Orifice jumper if previously removed.

2. Connect the T-5800 to the system, allow the system to come into control, and note the output pressure.

3. If the gain setting is specified on the control drawing, set the gain to this value. If not specified, increase the gain setting until the system becomes unstable and begins to cycle. Then decrease the gain setting slightly to remove the cycling effect.

Integral Time Adjustment (T-5800-2 Only)

Note: The Gain Adjustment section must be completed before moving to these steps.

1. Reconnect the PI jumper previously removed, in order to restore the PI function to the T-5800-2.

2. If the system response toward the set point is too slow, decrease the integral time and/or increase the Gain Adjustment dial settings by small increments each. If cycling occurs, increase the integral time and/or decrease the Gain Adjustment dial settings by small increments each.

Figure 5: Typical T-5800 Series Instrument

T-5800-3 and T-5800-4 Dual-Input Receiver-Controllers 1. From the control drawing and reset schedule

(Form #561), determine the minimum and maximum values of the Master “M” and Controlled Variable “CV” transmitters. An example of a typical reset schedule is illustrated in Figure 6.

2. Position the Ratio Selection jumper in the proper position, as determined on the control drawing (Example: A ratio of .83:1 means install the jumper in the 1:1 position).

3. Connect the T-5800 to the calibration kit, matching the gauge ranges on the kit to the corresponding Master “M” and Controlled Variable “CV” transmitters (Example: 0 to 100°F and 40 to 240°F, respectively).

Master Input Balance Adjustment (“R” Test Point)

Note: The previous section of this document must be completed before moving to these steps.

1. Apply a simulated Master “M” input pressure, equal to the midpoint of the working range according to the reset schedule (Example: 40°F).

2. Connect the hypodermic needle test probe assembly to test gauge G-4 on the calibration kit and insert the needle test probe into the “R” test point on the T-5800. Adjust the Master Input Balance screw to 9 psig.

3. Remove the needle test probe from the “R” test point and insert it into the “SP” test point location.

4. Set the Set Point dial (local or remote) to provide a 9 psig reading on test gauge G-4. Remove the test probe from the T-5800.


Figure 6: Typical Reset Schedule

Ratio Adjustment

Note: The Master Input Balance Adjustment (“R” Test Point) section must be completed before moving to these steps.

1. With the Master “M” input pressure still at the midpoint of the working range of the controlled device (Example: 40°F), apply a simulated Controlled Variable “CV” input pressure equal to the midpoint of its working range according to the reset schedule (Example: 130°F).

2. With the Ratio Selection jumper and Ratio Adjustment dial in the 1:1 position, rotate the dial to the calculated ratio value for the specific application (Example: Ratio of .83:1).

3. Adjust the set point (local or remote) to produce an output pressure equal to the mid-spring-range of the controlled device(s).

4. Apply a simulated Master “M” input pressure, starting at the minimum value of the working range according to the reset schedule (Example: 10°F).

5. Apply a simulated Controlled Variable “CV” input pressure which corresponds to the minimum Master value in Step 4 (Example: 180°F).

6. Determine what valve position on the operating system would be necessary to produce the desired “CV” value in Step 5. Rotate the Ratio Adjustment dial to produce this output pressure (Example: Approximately 6.5 psig assuming a Normally Open [N.O.] valve for this application).

7. Adjust the simulated input values to the other end of the reset schedule (Example: Master “M” = 70°F, Controlled Variable “CV” = 80°F).

8. Determine what valve position on the operating system would be necessary to produce the “CV” value in Step 7. Adjust the set point (local or remote) to produce this output pressure (Example: Approximately 10.5 psig).

Note: To determine if this controller will operate as desired when installed on the job site, go to the Operation: Simulator section and observe controller operation.


Gain Adjustment

Note: The Ratio Adjustment section must be completed before moving to these steps.

1. The T-5800 must be connected to the actual control system to adjust the gain. Remove the receiver-controller from the calibration kit and reconnect the Orifice jumper if previously removed.

2. Connect the T-5800 to the system, allow the system to come into control, and note the output pressure.

3. If the gain setting is specified on the control drawing, set the gain to this value. If not specified, increase the gain setting until the system becomes unstable and begins to cycle. Then decrease the gain setting slightly to remove the cycling effect.

Integral Time Adjustment (T-5800-4 Only)

Note: The Gain Adjustment section must be completed before moving to these steps.

1. Reconnect the PI jumper previously removed, in order to restore the PI function to the T-5800-4.

2. If the system response toward the set point is too slow, decrease the integral time and/or increase the Gain Adjustment dial settings by small increments each. If cycling occurs, increase the integral time and/or decrease the Gain Adjustment dial settings by small increments each.

Operation: Simulator The simulator can produce a system speed reaction in a Fast or Slow mode. The system speed is accomplished by setting the Gain Adjustment dial of the T-5800-1 test kit above (increase response) and below (decrease response) a setting of 10:1. (See Figure 7.)

The System Load Change knob is turned to cause the controller being checked to reposition the controlled device to a more open or closed position, simulating system offset. The output change will be different depending on the action (Direct Acting [D.A.] or Reverse Acting [R.A.]) of the controller being checked.

IMPORTANT: The Action Side jumper of the T-5800-1 test kit must match the action of the controller being tested.

Simulator Initial Setup 1. Set the Gain Adjustment dial on the T-5800-1 test

kit to 10:1, to simulate a normal system response. 2. Center the System Load Change knob. 3. Set the Action Side jumper on the T-5800-1 test kit

to match the action of the controller being tested.

Testing a Receiver or Pressure Controller Note: The Simulator Initial Setup section must be

completed before moving to these steps. 1. Furnish supply air (20 to 90 psig) to the “MAIN AIR

IN” connection of the calibration kit. 2. Connect the supply air connection from the test kit

to the “Supply” connection of the controller. 3. Connect the output of the controller to the

“Controller Output to System” connection. Note: If the controller does not have an output

gauge, connect a jumper tube to G-6.

Figure 7: Simulator Application

4. Connect G-7 to the “CV” or pressure connection on the controller. Identify proper scale on gauge G-7.

5. If not at the desired set point, turn the Set Point dial to the desired set point.

6. Set the Gain Adjustment or sensitivity dial and/or slider to the desired setting. Note: The controller should now be trying to

reach the set point. If the controller cycles, adjust gain, sensitivity, or throttling range.

On dual-input controllers, slightly adjust the Ratio Adjustment (authority) and Set Point dials to bring the “CV” temperature values to the desired values.

7. Once the controller has settled out, note temperature and output values.


JC 5383B Simulator Installation The following instructions are used to install a system simulator into an existing JC 5383 (X-200-173) Calibration Kit, thus creating a JC 5383A Simulator and Calibration Kit:

1. Remove everything from the side compartment of the JC 5383 (X-200-173).

2. Remove the calibration kit face plate. Depending on the age of the kit, four to five screws hold the plate on the kit.

3. Attach the supply air line “S” of the T-5800-1 test kit to the calibration kit “Supply” air circuit by drilling a 3/8 in. diameter hole into the compartment of the kit, as shown in Figure 8. This hole is 4 in. from the back of the inside of the kit and approximately 2 in. from the top edge of the kit.

4. Insert the simulator supply air tubing through the 3/8 in. diameter hole and attach the tubing to the calibration kit pneumatic circuit, as indicated in Figure 8 (after the “PRV” regulator). Cut tubing and attach with the “tee” fitting provided with the simulator.

Figure 8: JC 5383B Simulator Installation


5. Reattach the face plate and secure the holding screws.

6. Place simulator into side compartment of calibration kit with T-5800-1 near handle of kit.

7. The simulator is permanently attached to the kit using two mounting holes that are provided in the simulator plate. The location of these holes is indicated in Figure 8. The holes are approximately 1 in. and 3-3/4 in. from the outer edge of the kit. Use the pretapped holes in the simulator plate for a template. Use a No. 18 drill bit to create matching holes in the kit. The holes in the plate are tapped for a 10-32 in. screw.

Servicing the JC 5383 Calibration Kit Periodically check the accuracy of all gauges on the JC 5383A kit, utilizing a good master test gauge. Johnson Controls recommends a 4 to 6 in. test gauge with an accuracy of 0.1 psi be used.
