Parker Sporlan S3C - Configuration T: Remote Dual Temperature with EEV and Case EEPR; S3 C Case Control Setup for Configuration T

Bulletin 100-50-9.1 – Page 81
6.20 REMOTE DUAL TEMPERATURE WITH EEV AND CASE EEPR – CONFIGURATION T
The S3C case controller is capable of controlling and monitoring dual 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 per case 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 the EEV. The S3C valve module will drive the EEPR. The typical control method is to
regulate the average case discharge air temperature with the EEPR while allowing the EEV to control superheat. Note that the
optional liquid line solenoid (LLS) may be installed as one-per-case or one-per-line-up. Case numbers 2, 3, 4,…n will require
their own S3C case controller and S3C valve module. The case is toggled between its two operating temperatures either via the
building automation system (BAS) or with a locally installed physical switch. When the case controller receives a command to
change temperature, the EEPR will either open or close to lower or raise the case temperature, respectively.
To configure the S3C control package for configuration T
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 du (Dual
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.
7. Press the SET button when  (Expansion Valve Type)
is displayed. Use ▲▼ buttons to choose the Expansion
Valve Type based on the below chart; press SET.
