- 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

- 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
CC-100 Case Controllers

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.

Power 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.

Valve 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
