CC200 Input Wiring

Step 1: Make sure the power is OFF to the CC200 Main Controller.
Step 2: Determine what sensors will be needed and wire per the specification above.
a. If sensor need to be extended Emerson only supports heat shrink and solder.
Step 3: Determine how many coils are on the cases.
a. For multi-coil cases the CC200 supports one sensor per coil for discharge air, return air, defrost termination and coil outlet.
Pressure transducers for multi-coil cases may be installed one per coil or one for the entire case (parameter selectable).
b. For multi-coil cases the sensors on coil #1 will terminate on the CC200 Main Controller. Second and third sensor coils will require an Expansion Module per coil and each coil’s sensor will terminate on the each of the Expansion Modules.

CC200 Stepper Valve Wiring and Specifications

Each CC200 STEPPER VALVE output when configured as “Bipolar” is capable of supplying up to 500mA/phase and driving 12 Volt 2-Phase bipolar permanent magnet stepper valves with constant 12 volts using Full Step mode 4-step drive sequence. Bipolar stepper valves with phase resistance less than 26 ohms or that require a voltage chopper constant current driver, CANNOT be driven with the CC200 system.
Each CC200 STEPPER VALVE output when configured as “Unipolar” is capable of supplying up to 300mA/phase and driving 12 Volt 5-wire unipolar permanent magnet stepper valves with 1-2 Phase Half Step 8 pulse control sequence. Unipolar stepper valves with phase resistance less than 40 ohms CANNOT be driven with the CC200 system.

Stepper Valve (Sporlan CDS Only)

Stepper Valve| Bipolar| W2
76(White) – 77(Black)
W1
78(Red) – 79(Green)
Stepper Valve – Expansion Module| Bipolar| W2
33 (White) – 34 (Black)
W1
35 (Red) – 36 (Green)

Step 1: Make sure the power is OFF to the CC200 Main Controller.
Step 2: The CC200 Case control system (Main Controller + Expansion Modules) supports Electronic Expansion Valve (EEV) control using either Pulse Width Modulation (PWM) valves OR Stepper valves but NOT both.

The first case in a CC200 lineup (“a” Case) has support for control of Electronic Evaporator Pressure Regulation (EEPR) stepper valve.

PWM EEV 1 or Stepper EEV 1 is always located on CC200 Main Controller
PWM EEV 2 or Stepper EEV 2 is always located on Expansion Module 1
PWM EEV 3 or Stepper EEV 3 is always located on Expansion Module 2
EEPR Location
- When PWM EEV is used, EEPR is always located on CC200 Main Controller Stepper terminals
- When Stepper EEV is used, EEPR is located on the last Expansion Module Stepper terminals
  a.The wiring specification above is only for the Sporlan CDS and SER valves.
  b.If other manufacturer valves are used, refer to the manufacturer’s specification and contact Emerson for instructions on how to terminate.

Step 3: Refer to the drawing and specification for termination of the valve:

Step 1: Determine if you need an Expansion Module.
a. You will add an Expansion for a second or third coil. Each coil will have temp sensors and a transducer and will be wired to the respective Expansion Module.
Step 2: Addressing the Expansion Module
a. Set the address of each Expansion Module using the ON/OFF dip switch bank on the top left corner of the hardware (refer to figure below).
b. Expansion Module one must be set to address 1, Expansion Module two to address 2, Expansion Module three to address 3.
Step 3: Install the Expansion Module.
a. Make sure power is OFF to the CC200 Main Controller. Power will be restored in a later step.
b. Install Expansion Module 1 on the DIN rail adjacent to the CC200’s right side. The CC200 Expansion port terminal V+ should be aligned with Expansion Module 1 Expansion port terminal V+. Slide the Expansion Module into the CC200 Expansion port so both device’s Expansion port connectors fasten together.
c. If Expansion Modules 2 and 3 are present, connect to Expansion Module 1’s Expansion port using in the same manner described in the above step.
No wiring is needed between the CC200 Main Controller and CC200 Expansion Module. Power and communication are sourced from the CC200 Expansion port and passed through each Expansion Module Expansion port.
Step 4: Terminate sensors on the Expansion Module and refer to the drawing and specifications above for terminal numbers and how to terminate.
Once all sensor terminations are complete and the Expansion Module Expansion port is securely plugged into the CC200 Expansion port, restore the 24VDC supply power to the CC200 Main Controller. Once connected, the Expansion Module PWR ON LED will illuminate green indicating supply power is present.

CC200 Display Specifications

Step 1: Make sure power to the CC200 Main Controller is turned OFF.
Step 2: Make termination from the CC200 Main Controller to the CC200
Display.
a. It is critical that these terminations are made correctly as this can result in damage to both devices if not terminated correctly.
b. Clip and insulate shield at both ends of the Belden connection cable. Keep cable length at less than 50 ft (15 meters).
Step 3: Power ON the CC200 Main Controller.
