This paragraph describes the required wiring connections between the mechanical pump and the
Fuel Truck Controller.
Pulse Wires:
The pump outputs pulses to the system by means of the Pulser unit,
installed inside the pump. The Pulse rate per volume (liter/gallon)
is determined by the Pulser unit. It is programmed as a "factor"
by the OrCU Controller.
In Use Wires:
Some applications require a trigger signal to the OrCU controller. The
OrCU can operate with in-use signal to the MPI-C. This signal
indicates that a transaction is about to be made. Once the
transaction is initiated, the in-use switch must be turned off in
order to end the transaction.
Another option is not connecting the In Use wires. In that case, the
OrCU Controller will start a transaction as soon as the nozzle
antenna detects a authorization device.
Authorization Output
Wires:
The dispenser requires an authorization signal from the Fuel Truck
Controller to start a sale transaction. Without this authorization
signal, the electric valve (or pump) will not open and the sale
transaction will not begin. The Fuel Truck Controller sends the
authorization signal in the form of an DC power signal to the
valve. When the dispenser receives the authorization signal, fuel is
flow.
NOTE
In cases where fuel truck meters are required, it is
highly recommended to use
Liquid Controls (LC) or
Veeder-Root Meters
