9.3 CC-100 Case
Controllers
9.3.1 Inputs
The input connections to the CC-100 are made on the
left-hand side of the controller. Figure 9-14 shows 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 switch
es, 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.

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-
