Units with Optional Direct Submersible Drive
Power for the Subm Drive line originates from this input. 9800 Series dispensing units
equipped with the optional relays for direct submersible pump drive can be connected directly
to submersible pumps up to 3/4 HP at 115 VAC or 1-1/2 HP at 230 VAC. The gauge of this
wire should be determined according to the size of the motor, the voltage at which the motor
will be powered, and the distance from the breaker panel to the pump.
Submersible Starter Drive (Subm Starter Drive)
The Subm Starter Drive is a 115 VAC (230 VAC International) output used to control a
submersible starter relay. Two lines are provided for twins. This line is capable of supplying
300 mA of AC current to control the coil of the submersible motor contactor (starter relay).
This is sufficient for directly connecting to the popular models. However, refer to the
contactor (relay) manufacturer's data sheet for the sealed VA rating. Divide the sealed VA by
the coil voltage to determine the current. This line must not be connected directly to the
submersible pump, shorted to any conduit or chassis metal, or wired incorrectly, or the CPU
PC board will be instantly damaged. This line must be capped when not in use.
Submersible Drive (Subm Drive)
This line is always present for dispensers, but is active only when Subm Drive relays are
supplied. The Subm Drive is a 115/230 VAC (230 VAC International) output used to control
the submersible starter relay or submersible pump. When connected directly to the
submersible pump, the motor size cannot exceed 3/4 HP at 115 VAC or 1-1/2 HP at 230 VAC.
Two lines are provided for twins. In cases where both lines are controlling the same starter
relay or pump, they can be combined.
Reset Complete (Switch Detect)/Slow Flow
The Reset Complete/Slow Flow is a 115 VAC (230 VAC International) output which is used
to indicate that the reset process is complete and the unit is ready to dispense the product. It is
required when used with a TopKAT fuel management system. It may also be used to control a
remote (satellite) slow flow valve. Two lines are provided for twins.
Phase 2 Feed
The phase 2 feed 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. The Phase 2 Feed must be
switched through a separate relay to prevent false triggering of the authorization signal.
Light Feed
The Light Feed is a 115 VAC input required to power the fluorescent lights. In a site
configuration using multiple dispensers (or pumps), the power for the lights of up to 8 units
can be supplied by one breaker. This must be on a separate breaker from the Micro/Heater
Feed to reduce electrical noise and allow for separate control of the lights.
