Setting and checking current. To set or check current on the configurator with Gilbarco dispensers
connected, follow these steps.
1.
Disconnect power from the system. Disconnect POS cable from controller. Leave cable
connected between the main controller and configurator box.
2.
Remove cover from the configurator box (4x4 gold DBox connected to the DBox).
3.
Disconnect harness associated with DB09 male connector from the configurator board.
4.
Power system and, with multi-meter set for DC current, place (+) lead on pin 1 of connector
on configurator board and (-) on pin 8 of connector on board.
5.
Current reading should be approximately 45mA. If current is not close to 45mA, it may be
adjusted. Using a small screwdriver, adjust potentiometer on the board until correct current is
achieved.
6.
Once current has been set, power the system down and reconnect all connections.
7.
Apply power to system and continue normal operation.
Wayne/Dresser Dispenser/CAT
In addition to the general diagnostic procedures that should be employed when troubleshooting a
fuel system, there are some unique considerations when working with Wayne/Dresser dispensers and
readers.
Dispenser Computer Boards. Wayne/Dresser dispensers have different models of computer boards
to run the dispenser operation. These boards are the SC82 and the Duplex (SC86). The SC82 is
configured with dip switches, while the Duplex (SC86) is option-programmed. It is important to
obtain both the dispenser configuration as well as the version of software running the dispenser.
Current Level of DBoxes. The communication current level of Wayne/Dresser DBoxes or PIE’s DBox
should be 35mA. This signal current is generated by the PIE configurator box. Occasionally this
current level needs to be set to accommodate the Wayne DBox input circuitry. See Diagram: PCXZ
Connector/Jumper Layout in the PCXZ Installation section of this manual for details on altering this setting in the PIE configurator box.
Configurator Board LED Indicator for Open Loop Condition. The PIE Wayne/Dresser style
configurator board has an LED that will assist in determining if the current loop is open. If this LED
remains on solid with prices sent to the PCXZ controller, then there is a possibility of an open loop
condition. Check loop wiring between the PIE configurator and the DBox. Refer to the appropriate DBox
communication guide.
