6.6 REMOTE SINGLE EVAPORATOR WITH EEV – CONFIGURATION F
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 and
drive the EEV. The typical control method:
Without mechanical EPR: EEV will control case temperature with a minimum superheat setpoint.
With mechanical EPR: EEV will control superheat and the EPR will control case temperature.
The optional 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 F 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
