6.17 REMOTE MULTIPLE EVAPORATOR WITH 3 EEVS AND CASE EEPR – CONFIGURATION Q
The S3C case controller is capable of controlling and monitoring single temperature, multiple 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 and two S3C valve modules are required. The S3C case controller will control all case functions as well as
take all the desired sensor inputs for one evaporator and drive EEV1. S3C valve module 1 will take all the desired sensor
inputs for the second evaporator as well as drive EEV2. Valve module 2 will take all the desired sensor inputs for the third
evaporator as well as drive both EEV3 and the EEPR. The typical control method is to regulate the average discharge air
temperature of all case evaporators with the individual case EEPRs while allowing the EEVs to control superheat. This
configuration only supports Discharge Air control. The optional liquid line solenoid (LLS) may be installed as one-per-case
or one-per-line-up. In this configuration, each case in the line-up has its own EEPR connected to the S3C valve module.
Case numbers 2, 3, 4,...n that have two or three evaporators will require their own S3C case controller and valve module
as well. All case functions will be synchronized across the line-up in this configuration with the exception of temperature
control.
To configure the S3C control package for configuration Q
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.
