Troubleshooting
The SPGC-220 has a microprocessor that allows the unit to diagnose abnormal conditions
and communicate them through an audible alarm and LEDs on the front panel. The following
describes these indications:
• When the display is lit, 200-250 VAC power is applied to the SPGC-220.
• If the display is flashing "run," the pump motor assembly (PMA) is running.
NOTE: If the display is "IdLE," even when a dispenser is activated, check the dispenser hook signal
terminals on the SPGC-220. If 120–240 VAC is across the hook terminal, and the switch settings
are correct, contact FFS Technical Support for assistance.
CAUTION
: If the display flashes "run," even when all the dispensers are turned off, there may
still be power present at the SPGC-220 hook terminal. If this is the case, contact FFS Technical
Support for assistance.
• If the display is flashing and the audible alarm is beeping, there is an abnormal condition.
Note the flashing code on the display, and refer to the appropriate troubleshooting topic.
Disabling the audible alarm
Press the Silence/Calibrate button briefly to silence the audible alarm without resetting the
controller.
Reset
Before you correct an abnormal condition (the display is flashing red and the alarm is beeping),
do the following:
1. Note the flashing code shown on the display.
2. Reset the controller by pressing the Reset button for approximately three seconds.
3. Release the Reset button when the display goes blank.
4. Check for proper operation.
5. If the controller operates correctly, the abnormal condition is resolved and normal
operation is restored.

Support for assistance, if needed.
