Table 9-4- Default Input Assignments

If your case has sensors or switches that are not listed in the defaults above, or if it is otherwise impossible to use all the defaults for the CC-100, the input type can be changed in the system software. Refer to P/N 026-1603, Programmer’s Guide, for instructions on how to do this.

Auxiliary Analog Input

Figure 9-14- Auxiliary Analog Input

The four-pin analog input is designed to be connected to a Relative Humidity Sensor (P/N 203-5750). The wiring harness (P/N 335-3252) designed specifically for the input must be used. Wiring for this device is shown in Figure 9- 14.

Hand-Held Terminal Jack

The Hand-Held Terminal jack on the left side of the CC-100 is where a CPC Hand-Held Terminal (HHT) may be connected. The HHT may be used to program setpoints and change settings in a CC-100. In addition, you may use an HHT to send a case into defrost (or terminate an exist- ing defrost), force a case into wash mode, and bypass or

override numerous case functions.

The Hand-Held Terminal jack also doubles as a service pin, used when commissioning a CC-100. Plugging the Hand-Held Terminal into a CC-100 sends the special Ech- elon ID number to the E2.

9.3.2Power Module Wiring

CC-100s are powered by 24VAC Class 2 power, which is supplied by a CPC power module.

The case power module should be connected to either a 120 VAC or 240 VAC single phase power source (which- ever is necessary for the model ordered). Complete wiring of the case controller power module, including lights, fans, defrost, and anti-sweat heaters, is diagrammed in Figure 9-15. Follow all local, NEC, and UL wiring practices.

Power is supplied to the CC-100 via the output cable harness.

9.3.3Valve Cable

The six-pin connector on the right-hand side of the

CC-100 is where the liquid stepper or suction stepper must be connected. The CC-100 uses this connection to control the stepper motors and change the position of the valve aperture.

All valve cable harnesses have a six-pin male connec- tor that plugs into the CC-100’s VALVE port. Plug this connector in so that the tab on the top of the connector is facing up.

For instructions on connecting the valve cable to the pulse or stepper valve, refer to the instructions below for
