Parker Sporlan S3C - Configuration B: Self-Contained Single Evaporator with EEV; S3 C Case Control Setup for Configuration B

Bulletin 100-50-9.1 – Page 27
To configure the S3C control package for configuration B
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 e; press SET. This will configure the controller to
support a self-contained 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 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.
5. Press the SET button when  (Application Type)
is displayed. Use ▲ button and scroll to (Single
Temperature Case); press SET.
6. Press the SET button when  (Local Stepper Valve
Configuration) is displayed. Use ▲ button to scroll to
(Electronic Expansion Valve); press SET. This 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.
8. Press the SET button when e (Number of
Evaporators) is displayed. Use the ▲ button and scroll
to 1 (1 Evaporator); press SET.
6.2 SELF-CONTAINED SINGLE EVAPORATOR WITH EEV – CONFIGURATION B
The S3C case controller is capable of controlling and monitoring single temperature, single evaporator self-contained
refrigerated fixtures. In this scenario, one S3C case is required. The S3C case controller will control all case functions as
well as take all the desired sensor inputs and drive the EEV. The typical control method is to allow the EEV to regulate
superheat. The controller will pulse the optional liquid line solenoid and open/close the EEV 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 EEV.
