CPU Board Jumper Configuration
Stand Alone Mode - Setting Jumpers
In the Stand Alone mode, the dispenser does not require an outside "authorization" signal from any
console or control unit. When the handle is lifted, the dispenser "authorizes" itself and the dispenser
resets and the sale begins.
Jumper Header JP1 is a 9 pin jumper header. Position 5 is for putting the dispenser in the "Stand
Alone" or "Console" mode. Removing the jumper from JP1 position 5 puts the dispenser in the Stand
Alone mode.
Setting the Jumpers— The jumpers should be set with power off and are only "read" at boot-up (power
up).
WARNING - DO NOT SET OR REMOVE JUMPERS WITH DISPENSER POWER TURNED ON!
DAMAGE TO THE DISPENSER MAY RESULT. ALWAYS MAKE SURE DISPENSER POWER IS OFF
AND THE BACK-UP BATTERY IS BYPASSED WHEN ADDING OR REMOVING JUMPERS!
The 9 position Jumper Header is located on the CPU board. It is used to set the hose position address
and to program the dispenser.
Jumper Positions 1 - 4 - (Fueling Point Address - Up to 16 fueling position addresses). Use jumper
positions 1 through 4 to set the dispenser address. Normally, Bennett pumps do not need an address
set when using current loop communications but with RS 485 style communication an address must be
set for the 3rd party device or console to know which fueling point it is talking to. The first four rows of
pins (on jumper header JP1) represent a binary number whose greatest value is 16 (or 0-15). The
fueling point address must be set to identify each hose position / fueling point using these jumpers. See
the chart on the next page for details on how to set the address for a specific fueling point number using
the jumpers on the first four rows of jumper header JP-1.
Jumper Position 5 - Console or Stand Alone -
In - Console (or Mechanical)
Out - Stand Alone
Jumper Position 6 - Motor delay (suction pumps without valves). This function allows a 2 second delay
preventing the dispenser from turning on immediately when the pump handle is lifted. This would be
used on a dispenser with self contained pumps and no valves. Set the dispenser for the two second
delay so that the motor does not come on immediately when the handle is thrown allowing the dispenser
to pump through a hose without a valve before the dispenser resets.
In - 2 second delay
Out - No Delay
Jumper Position 7 - Leak Detector Pre-charge - This function allows the system to energize the
submerged pump pressurizing the line to check for leaks before the valve opens. The jumper should be
out in most cases unless the leak detectors routinely trip (very slow flow from the nozzle - then use 9
seconds).
In - 9 seconds
Out - 2 seconds
