Setting and checking current. To set or check current on the configurator with Wayne/Dresser
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 (4 x 4 gold DBox connected to the Wayne/Dresser ).
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 35mA. If current is not close to 35mA, 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.
Tokheim Electronic Dispenser/CardScan
In addition to the general diagnostic procedures that should be employed when troubleshooting a
fuel system, there are some unique considerations when working with Tokheim dispensers and
readers.
Dispenser Communication Methods. The configurator box for the PCXZ system must match the
Tokheim distribution box. Tokheim uses two communication methods to talk to their distribution
boxes, RS422 and Tokheim proprietary. Below is a table describing which method is used by each
DBox model number:
Tokheim Proprietary ÿ 67, 67A, M98, M94, 67B
RS422 ÿ 67B
M98 and M94 DBoxes. If the Tokheim distribution box is an M98 or M94 power center, make sure
all switches are turned on. This box has a power switch and a manual override switch for each
dispenser position. It also has master power switches on the outside and inside of the box. Both must
be on for correct operation.
Dispenser IDs. The M98 and M94 boxes are only capable of running up to 8 dispensers (fueling
positions). The dispenser IDs are determined by the control board position to which the dispenser is
wired. Jumper settings in these boxes allow selection of box IDs of 1
ÿ 8 or 9 ÿ 16. If the setting is
incorrect, the DBox will not correctly answer commands issued by the PCXZ controller. No dispenser
polled totals are reported for the M98 and M94 DBoxes.
