5.4 Electromechanical Totalizer
An externally visible electromechanical non-resettable totalizer is provided as standard
on all models.
The totalizer(s) records up to seven whole digits (9,999,999).
The totalizer can be viewed from the front of the unit and is located next to the “Status”
display for volume only units or “PPU” display in the case of units with pricing.
Electronic totals are also available. See Section 5.5, Dispenser Statistics & Diagnostics.
5.5 Restarting After Power Failure or Shutdown
After loss of power, the display accurately displays the amount of the sale, in money (if
applicable) and volume, 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 do the following:
Step 1 Ensure all nozzles on the side are in their nozzle boots.
Step 2 Authorize the dispenser.
Step 3 Remove the nozzle from the nozzle boot. The dispenser should operate normally.
If the dispenser does not resume normal operation, try cycling power as described
in the next section.
5.6 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 error codes. Record the displayed error message. It may be
possible to restart the dispenser by the following sequence:
Step 1 Ensure all nozzles are properly seated in the nozzle boot.
Step 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 annunciator will again sound.
Step 3 Authorize the dispenser.
Step 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
continues to be displayed, consult appropriate service personnel. Be certain to give the
service personnel the amount at which the dispenser stopped and the exact error message.
