Pulse Input
Wires

The dispenser outputs pulses to the system by means of the pulser unit,
installed in accordance with the manufacturer instructions. The pulse rate
per volume (liter/gallon) is determined by the pulser unit. It is programmed
as a “factor” in the SiteOmat.

Handle Status
Input Wires

The handle signal is used to signal the system that the pump is “In Use”
mode. When the dispenser handle is lifted, this contact closes. This signals
the system that the pump is “In Use” or that the transaction ended.

Authorization
Output Wires

The dispenser requires an authorization signal from the TopKAT PLUS to
start a sale transaction. Without this authorization signal, the electric valve
(or pump) does not open and the sale transaction does not begin. The
TopKAT PLUS switches the AC power signal to the valve. When the
dispenser receives the authorization signal, fuel starts to flow. This signal is
also referred to as the LOAD.

TopKAT PLUS ratings for above signals are as follows:
