Installation

Gilbarco Interface Unit v2.1

Gasboy CFN Series

If the system does not operate

One or more pump control units may fail to come up or stay up. Messages may print on the log
about pump control units going up and down. You may see PUMP OUT OF SERVICE error
messages when you hit START on the Check Point or Profit Point, or CAN’T ACTIVATE if you
use the ACTIVATE PUMP command. PRINT DIAGNOSTICS may reveal that a pump control
unit is down.

Try a memory loss at the interface. Setting DIP switch bank 2, position 2 to OPEN

momentarily while you cycle the AC power or press the reset button. Disconnect the interface
from its RS485/422 line to the Site Controller and wait for five minutes, then reconnect the line.

If there is still a problem, try putting all pumps in ISOLATE at the distribution box. Switch

pumps back to NORMAL one at a time, waiting for the associated pump control unit to come up
each time. Sometimes you will see a pump control unit that has been up for a while suddenly go
down when you switch some pump to NORMAL.

If a pump newly switched in always takes down the same other pump, the pump just
switched in may be set to the wrong poll address.

If a newly switched in pump takes down more than one other pump, it may have a faulty
circuit board in it, or the current loop field wiring may be faulty. If there are still prob-
lems, go back and re-check all preceding parts of setup. If the problem still remains after
that, you will need to obtain further technical assistance from Gasboy.

If CRINDs do not operate at all, first check the CRIND displays. They will say either PLEASE
PAY INSIDE or . In the first case, the CRIND is not seeing any
communication with the interface unit. In the second case (the message with the brackets), the
CRIND is communicating with the interface unit, but the Site Controller is not.

If the CRINDS operate but the keys on the keypad do not get the proper responses, check

the CRIND keypad programming.

Transferring from Gilbarco console to Gasboy interface

During setup it is sometimes useful to check out the pumps using a Gilbarco console, such as the
Transac T-12. If you do this, make sure all pumps are deauthorized before disconnecting the
current loop wiring from the Gilbarco console and connecting it to the Gasboy interface.

Failure to follow this precaution will cause the Gasboy unit to take an excessive amount of

time before the pumps are fully operational. Unassigned transactions may also result, causing the
Site Controller to disable pumps. The Site Controller command ENABLE PCU must be used to
bring the pumps back to operating status if this happens.

POS says PUMP BUSY on START key

This is a normal message if a transaction has gone payable due to pulser timeout or operator
intervention, and the handle on the pump has not yet been lowered. Lowering the handle on the
pump should restore normal operation.

Rarely, Gilbarco pumps in this condition do not respond to the handle. Remove power from

the pump briefly. In most cases this cures the problem.

If the problem persists, and if you have a Site Controller II version 2.0B or greater, and

Gilbarco interface firmware 1.2L or 2.0, or greater, you may use the Site Controller TEST PCU
command to restore normal operation.

If the message results from a Site Controller malfunction, try the ENABLE PUMP;A

command. Otherwise, a Gilbarco service representative must master reset and reprogram the
pump, or a Gilbarco console must be connected to the pump and the START or AUTHORIZE
key used.

This problem has been observed in several different models of Gilbarco pumps, including

very old models, but appears to be more common in newer (The Advantage) models.
