6.5 REMOTE SINGLE EVAPORATOR – CONFIGURATION E
The S3C case controller is capable of controlling and monitoring single temperature, single evaporator refrigerated fixtures
installed as a line-up. The case shown in the diagram below is the lead case of the line-up. In this scenario, one S3C case
controller is required. The S3C case controller will control all case functions as well as take all the desired sensor inputs.
The typical control method:
Without mechanical EPR: TEV will control superheat and liquid line solenoid will control case temperature using cut-in/
cut-out method.
With mechanical EPR: TEV will control superheat and the EPR will control case temperature.
The liquid line solenoid (LLS) may be installed as one-per-case or one-per-line-up if no EPR is used or if an EPR per line-
up is used. Case numbers 2, 3, 4,...n will require their own S3C case controller as well.
To configure the S3C control package for configuration E
shown above, follow these directions:
If the controller has not been factory set, then upon initial
start-up, the controller will be in set-up mode and the
screen will display  (for self-contained case).
1. Press the SET button, then use ▲▼ buttons to scroll
to o; press SET. is will congure the controller to
support a remote case.
2. Press the SET button when  (Rack Identier)
is displayed. Use the ▲▼ buttons to congure the 4
character Rack Identier. Note: Push ▲ button for
numeric, ▼ for alpha characters. When satised
with each digit, press the SET button to go to the next
digit. Pressing SET multiple times will move to the next
parameter.
3. Press the SET button when ud (Line-up Identier)
is displayed. Use the ▲▼ buttons to congure the 4
character Line-up Identier. Note: Push
▲ button for
numeric,
▼ for alpha characters. When satised
with each digit, press the SET button to go to the next
digit. Pressing SET multiple times will move to the next
parameter.
4. Press the SET button when d (Case Identier)
is displayed. Use the ▲▼ buttons to congure the 4
character Case Identier. Note: Push ▲ button for
numeric, ▼ for alpha characters. When satised
with each digit, press the SET button to go to the next
digit. Pressing SET multiple times will move to the next
parameter.
5. Press the SET button when  (Application Type) is
displayed. Use the ▲ button and scroll to  (Single
Temperature Case); press SET.
6. Press the SET button when  (Local Stepper Valve
Conguration) is displayed. Use the ▲ button to scroll
to oe (None for ermostatic Expansion Valve); press
SET.
