    - General Rules for Wiring CP-8102 to Controlled Device(s)
      - 1. Never connect red lead (or +20 terminal) of any controlled device which has a regulated power supply to the red lead (or +20 terminal) of any other controlled device (see Figure 5).
        
        2. Controlled devices (MP-52XX) with unfiltered and unregulated power supplies must be filtered. CP-8102 will provide filtering for a maximum of two MP-52XX by connecting the two red leads together at the controllers +20 terminal (see Figure 6).
        
        3. Controlled devices with filtered and unregulated supplies: Up to six controlled devices with the red leads (+20 terminals) can be connected together. Number of units paralleled depends on the current (mAdc) requirements of the controller or adaptor.

    - FIELD CHECKOUT
Note: The following procedures can be used for either reverse or direct acting connected CP-8102 controllers.
- 1. Initial Conditions for CP-8102:
  - a. Jumper between AB2 and AB3 disconnected.
  - b. 20 Vdc +1 -1.5 Vdc (23 mA) applied to the +20 and common terminals. This power is normally supplied by the controlled device.
  - 2. Connect a 20,000 ohm/volt DC VOM meter between the OP1 (+) terminal and COM (-) terminal of the CP-8102. Use a 20 Vdc or less range.
  - 3. Disconnect the temperature sensing element A from the ISA terminals of the CP-8102. Short ISA terminals together and VOM reading should be 1 Vdc or less if bridge A is direct acting and more than 15 Vdc if bridge A is reverse acting.
  - 4. Open ISA terminals and VOM reading should be greater than 15 Vdc if bridge A is direct acting and less than 1 Vdc if bridge A is reverse acting.
  - 5. The CP-8102 is a good unit if it passes tests in steps 3 and 4. Replace the unit if tests 3 and 4 are not met.

- FIELD CALIBRATION PROCEDURES FOR CONTROLLERS WITH ONE AND TWO INPUTS
  - 1. Initial Conditions for CP-8102:
    - a. Setpoint A set for: 70F.
    - b. Setpoint B set for: 70F
    - c. Ratio adjustment set for: 1:1.
    - d. Throttling range adjustment set for: 3F.
    - e. Jumper between AB2 and AB3 disconnected.
    - f. 20 Vdc (23 mA) applied to the +20 and common terminals. This power is normally supplied by the controlled device.
    - 2. Connect a 20,000 ohm/volt DC VOM meter between the OP1 (+) terminal and COM (-) terminal of the CP-8102. Use a 20 Vdc or less range.
    - 3. Calibration of A input. Use one of the following two methods.
      - a. Temperature measurement methods:
      - b. Sensing element substitution method:
Note: Method B above does not calibrate out any errors due to sensing element tolerances or wire lead resistance.
- 4. Calibration of A input complete.
- 5. Reconnect jumper between AB2 AB3.
- 6. Calibration of B input. Use one of the following two methods.
  - a. Temperature measurement method:
  - b. Sensing element substitution method:
Note: Method B above does not calibrate out any errors due to sensing element tolerances or wire lead resistance.
- 7. CP-8102 calibration is complete. Remove all test meters, test resistor, etc. Reconnect all elements, place setpoints, throttling range and ratio adjustments as required for the application.

    - 2. Connect D.P.D.T. switch (CYZP-11 or equivalent) according to Figure 15.
Note: Switch contacts should have pilot duty ratings and maintain a 1 ohm or less contact rating over its normal life.
- 3. No recalibration of CP-8102 is required.
