Parker Sporlan S3C - Configuration D: Self-Contained Multiple Evaporator with 3 EEVS; S3 C Case Control Setup for Configuration D

Bulletin 100-50-9.1 – Page 33
To configure the S3C control package for configuration D
shown above, follow these directions:
If the controller has not been factory set, then upon ini-
tial 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
e; press SET. This will configure the controller to sup-
port a self-contained case. 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.
2. 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.
3. Press the SET button when d (Case Identifier)
is displayed. Use the▲▼buttons to configure the 4
character Case Identifier. Note: Push ▲ button for
numeric, ▼ for alpha characters. When satisfied
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 (Application Type)
is displayed. Use ▲ button and scroll to  (Single
Temperature Case); press SET.

6.4 SELF-CONTAINED MULTIPLE EVAPORATOR WITH 3 EEVS – CONFIGURATION D
The S3C case controller is capable of controlling and monitoring single temperature, multiple evaporator self-contained
refrigerated fixtures. 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 allow the EEVs to regulate superheat. The controller will pulse the optional
liquid line solenoid and open/close the EEVs to control case temperature using the cut-in/cut-out method. The liquid line
solenoid (LLS) is optional since flow may be stopped by closing the EEVs. 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.
