Control Lines for Mechanical Pumps/Dispensers Mechanical Interface Option
Submersible Feed, Submersible Drive
This is a 115 VAC input which is supplied to the input side of one of the internal switches of
the electric reset. This line should be switched through the TopKAT and only be on when the
pump/dispenser is authorized or in manual mode. When the reset finishes its cycle, the 115
VAC input to the switch is passed through as an output (submersible drive) to drive a starter
relay or to directly drive a submersible motor up to 3/4 HP at 115 VAC or 1-1/2 HP at 230
VAC. Any submersible motor exceeding this limitation must use a starter relay.
Note: 230 VAC is developed across a motor when the other leg of the motor is connected to a
Phase 2 Feed.
Reset Complete (Switch Detect)
This is a 115 VAC output which is used to indicate the reset is complete and the pump/
dispenser is ready to dispense product. Two lines are provided for twins. This line should
only be used when monitoring of the pump/dispenser is desired (such as when used with a fuel
management system). This line must be capped when not in use.
Light Feed
This is a 115 VAC input required to power optional fluorescent lights that may be available in
a pump/dispenser. In a site configuration using multiple dispensers (or pumps), the power for
the lights of up to eight units can be supplied by one breaker. The light feed is not controlled
by the TopKAT.
Light Neutral
This is a return line for AC current from the lights to the breaker panel.
Phase 2 Feed
This is a hot feed which is the opposite phase of the pump motor feed. This line and the pump
motor feed are used for 230 VAC motor applications.
Pulser - Mechanical Pump
This supplies a DC output which is provided to indicate the quantity dispensed.
