15. SYSTEM START UP
15.1 CHARGE PRO
The S3C control system includes “Charge Pro” feature. It
may be used in preparation of a new start up. When selected,
this mode opens all refrigerated display case valves to allow
evacuation and refrigerant charging. This feature is manu-
ally initiated through the display and automatically resumes
control once refrigerant starts feeding the evaporator and
proper system conditions are met. While in this mode, the
Quick View indicators will blink orange and the display will
show
hg
.
Note: Charge Pro mode will not initiate if the
refrigerated display case:
• Uses an EEV and the S3C is missing the Coil Out sensor.
• Uses a TEV and the S3C is missing the control
temperature sensor (Discharge or Return Air).
1. From the
default
display, press the  button. The
display will show
  
.
2. Use the ▲▼ buttons to enter the Service password and
press
SET.
3. Press the
▼
button to scroll to hg (Charge mode);
press
SET.
4. Press the
▲
button to scroll to o ; press
SET.
This will
turn on Charge Pro.
Charge Pro will exit automatically and will resume control
once enough refrigerant has been added to the rack.
To Exit thru the Display:
1. From the
default
display, press the

button. The
display will show    .
2. Use the
▲▼
buttons to enter the Service password and
press
SET.
3. Press the
▼
button to scroll to
hg
(Charge mode);
press
SET.
4. Press the ▲ button to scroll to
off
; press
SET.
This will
turn Charge Pro off for that case and all the other cases
in its assigned line-up.
15.2 VALVE INITIALIZATION
All stepper valves are initialized on power up to establish
the 0% open or “home” position. The initialization routine
is common when using open loop control systems to
ensure that the valve position is synchronized with the
control output. During normal operation, the stepper
valves will be initialized if:
• Valve is at 0% and it has been 24 hours.
• The S3C Case Control or Valve Module has been power
cycled.
• Valve configurations are changed thru the

menu.
• During start up, the S3C Case Control scans all sensor
inputs both local and those present on any attached
S3C Valve Modules in order to detect available sensors
for control and monitoring. If a sensor required for any
configured control operation is not detected, an alarm
is generated. If a new sensor is added then a sensor scan
must be initiated using the Display Module (DM) to add
the new sensor to the detected sensor list in the control.
(See Service Menu to reset)
The S3C features Evaporator Fan Fault detection. During
start up a baseline fan current is determined. If a fan is
changed or replaced, this baseline must be recalculated.
This is initiated by user input using the Display Module.
(See Service Menu to reset.)
