Parker Sporlan S3C - Configuration L: Remote Multiple Evaporator with 3 EEVS; S3 C Case Control Setup for Configuration L

Bulletin 100-50-9.1 – Page 57
6.12 REMOTE MULTIPLE EVAPORATOR WITH 3 EEV – CONFIGURATION L
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 one S3C valve module 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. The S3C valve module will take all the desired sensor inputs for the second
and third evaporators as well as drive both EEV2 and EEV3. The typical control method is to regulate the individual discharge
air temperature of each evaporator with the EEVs. The optional liquid line solenoid (LLS) may be installed as one-per-case or
one-per-line-up. Case numbers 2, 3, 4,…n that have two or three evaporators will require their own S3C case controller and S3C
valve module as well.
If a liquid line solenoid is used, it must be installed on the common liquid line feeding the evaporators and it should be wired into
the case controller. This configuration only supports Discharge Air control.
To configure the S3C control package for configuration L
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. P ress 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.
