Parker Sporlan S3C - Configuration I: Remote Single Evaporator with EEV and Circuit EEPR; S3 C Case Control Setup for Configuration I

6.9 REMOTE SINGLE EVAPORATOR WITH EEV AND CIRCUIT EEPR – CONFIGURATION I
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 and one S3C valve module are required. The S3C case controller will control all case functions as well as take
all the desired sensor inputs and drive the EEV. The S3C valve module will drive the EEPR. The typical control method
is to regulate the average discharge air temperature of the evaporators on the line-up with the EEPR while allowing the
EEV to control superheat. The optional liquid line solenoid (LLS) may be installed as one-per-case or one-per-line-up. In
addition, only one case in the line-up (lead case) needs an EEPR connected to a S3C valve module. Case numbers 2, 3,
4,…n will require their own S3C case controller but not a S3C valve module with an EEPR if they share a common suction
line with the lead case shown in the diagram below.
To configure the S3C control package for configuration I
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  (Electronic Expansion Valve); press SET. is
is the valve that is attached to the main S3C Case
Controller.
