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 Eche-
lon ID number to the E2.

CC-100s are powered by 24VAC Class 2 power, which 

is supplied by a Emerson Retail Solutions 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 
9-16. Follow all local, NEC, and UL wiring practices.

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

harness.

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 

the appropriate cable type.
P/N 335-3263 (Pulse Valve)

Figure 9-17 shows the connections for pulse valve 1 

and pulse valve 2. The pulse valve 2 leads (BLACK/
GREEN) may be clipped if a second evaporator is not 
present on the case.

The 335-3261 valve cable is equipped with a four-pin 

male connector that plugs into a four-pin female connector 
on the valve. Plug the valve cable connector into the valve 
connector.
P/N 335-3260 (Generic Stepper and Emerson Flow 
Controls ESV Valve)

The 335-3260 valve cable has six flying leads for con-

nection to a stepper valve. Four of these leads connect to 
the stepper motors, while the other two serve as the power 
wiring (+12VDC and ground).

The pinout for this valve cable is shown in 



Figure 9-18. Table 9-5 shows how to hook the flying leads 
to Emerson Flow Controls ESR, Emerson Flow Controls 
ESV, and Sporlan SEI & CDS valves.
