Control Lines
The resistor assembly is 8.2K OHM, 10 Watt (P/N C05818) for 115/230 VAC domestic and
30K OHM, 10 Watt (P/N C06683) for 230 VAC international wiring. The TopKAT and CFN
systems require the resistor assembly only when they are used with the 9800 pump/dispenser
operating in standalone mode. Operating the 9800 in standalone mode with a TopKAT
requires the TopKAT mechanical interface option; with a CFN system, requires an optional
mechanical pump control unit. This line also supplies the power which is switched to the slow
flow and fast flow valves along with the switch detect signal. Two lines are provided for twins.
If the 9800 is to be controlled through authorization of this line, special care must be taken in
the wiring of the submersible control lines when a common submersible is used for more than
one hose outlet. See “Submersible Starter Drive” & “Submersible Pump Drive” for more
information.
Units with Standard Submersible Drive (SubM Drive)
Power for the SubM Drive line originates from this input. The submersible starter relay line, in
standard remote dispensers, is not capable of directly powering a submersible pump. A starter
relay must be used. The control lines for twin remote dispensers can be combined together and
powered by one breaker if individual control of each side is not desired. In a site configuration
using multiple remote dispensers, the power for the control lines of up to eight hose outlets (8
singles or 4 twins) can be supplied from one breaker.
Units with Submersible Drive Relay Option
Power for the SubM Drive line originates from this input. 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 Int'l) output used to control a submersible
starter relay. Two lines are provided for twins. This line is capable of supplying 300mA of AC
current to control the coil of the submersible motor contactor (starter relay). This is sufficient
for directly connecting to the popular models, but if in doubt, check the contactor (relay)
manufacturer's data sheet for the sealed VA rating. Divide the sealed VA rating by the coil
voltage to determine the current.
CAUTION CAUTION
This line must not be connected directly to the submersible pump, shorted to any
conduit or chassis metal, or mis-wired, or the CPU PC board will be instantly
damaged.
This line must be left capped when not in use. Follow the checks in Section 6 prior to applying
power, to avoid accidental damage.
