4.5 Restarting After Power Failure or Shutdown
After loss of power, the display accurately displays the amount of the sale, in money and vol-
ume, for approximately 15 minutes. When power is restored, all sales information returns to
the displays. Any sales in progress will be ended; old sales should be paid and the dispenser
reauthorized if more product is to be dispensed.
If the dispenser does not operate properly when power is restored (does not deliver product, or
does not reset), record both the money and volume shown on the display (so sales can be paid
for) and perform the following:
1. Ensure all nozzles on the side are in their nozzle boots.
2. Authorize the dispenser.
3. Remove the nozzle from the nozzle boot. The dispenser should operate normally. If the dis-
penser does not resume normal operation, try cycling power as described in the next sec-
tion.
4.6 Cycling Power to Clear Faults
If a fault in the dispenser is detected by the computer, an error message will be displayed in
the sale display as described in Section 4.7. Record the displayed error message. It may be
possible to restart the dispenser by the following sequence:
1. Ensure all nozzles are properly seated in the nozzle boot.
2. Turn the control power circuit breaker off for approximately five seconds; the dispenser
annunciator will sound. Turn the control power circuit breaker on; the dispenser annuncia-
tor will again sound.
3. Authorize the dispenser.
4. Remove the nozzle from the nozzle boot. The dispenser should operate normally.
If it is not possible to restart the dispenser using this procedure, or if an error message contin-
ues to be displayed, consult appropriate service personnel. Be certain to give the service per-
sonnel the amount at which the dispenser stopped and the exact error message.
