9.3CC-100 Case Controllers

9.3.1Inputs

The input connections to the CC-100 are made on the left-hand side of the controller. Figure 9-14shows the CC-100 input connections.

Temperature and Digital Sensors

The six two-pin Molex connectors on the left-hand side of the unit (numbered 1 through 6) are where the case’s temperature probes, coil inlet/coil outlet sensors, and other digital switches and contacts are connected. Emerson Retail Solutions temperature sensor leads are equipped with male connectors that plug in to these recep- tacles.

For digital switches and sensors such as dual-temp and clean switches, Emerson Retail Solutions supplies a digital output harness (P/N 335-3264) that consists of a connector with a two-wire pigtail. These wires may be spliced on to the switch or digital sensor leads. The connector is designed to snap in to one of the six inputs.

Connection

In order to function correctly, the CC-100 needs to know the function of each of the sensors plugged into inputs 1 through 6. For example, a CC-100P liquid pulse controller needs to know which of the six sensors is the coil in sensor, which is the coil out sensor, etc.

Each of the six inputs have a default input type assign- ment based on the type of CC-100 (either Liquid, or Suc- tion). If the sensors in your case match the default sensor types, plug each sensor into the appropriate receptacle.

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.

Auxiliary Analog Input

Figure 9-15- 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 9-15.

Hand-held Terminal Jack

The Hand-held Terminal jack on the left side of the CC-100 is where a Emerson Retail Solutions 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 existing defrost), force a case into wash mode, and bypass or override numerous case func-
