3 SUBM. STARTER DRIVE line can supply 300 mA AC maximum to control submersible
starter relays.
CAUTION
This line must not be directly connected to a pump.
4 External submersible relays are required unless the remote dispenser is equipped with the
submersible drive relay option. The submersible drive relay option provides a SUBM PUMP
DRIVE line (Blue 14) which can directly drive a submersible pump up to 3/4 HP at 115 VAC
or 1-1/2 HP at 230 VAC. The 14 AWG SUBM FEED and SUBM PUMP DRIVE wires are
always present. Verify that the submersible drive relay option is installed prior to wiring. The
power supplied to the CONTROL/SUBM FEED must be able to handle the load of the
submersible pump.
5 RESET COMPLETE (switch detect) line can supply 170 mA AC maximum for connecting to
fuel management system circuitry and in applications where control of a remote slow flow
valve (satellite) is required.
6 FAST FLOW line can supply 170 mA AC maximum is provided to allow for control of a
satellite along with remote control or monitoring of the fast flow valve found in the pump.
7 FAST SAT. RETURN and SLOW SAT. RETURN lines are used when the remote dispenser
is supplied with satellite piping and connected to the satellite in a manner to prevent both the
remote dispenser and satellite from dispensing product simultaneously. See the satellite wiring
diagrams found in this section for correct connection of these lines. These lines are not
connected as they leave the factory.
8 If the CONTROL/PUMP MOTOR FEED line is controlled by a fuel management system
using solid state relays, a resistor assembly must be installed between the Control Feed line
and Feed Neutral to prevent false triggering of the authorization input. 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.
9 Use the wire size chart listed on page 5-4 when determining the wire size for the control
wiring.
10 When used with an aboveground tank, the valve mounted at the tank MUST NOT be
connected to the RESET COMPLETE or SUBM STARTER DRIVE lines. If the optional
internal relay kit is installed AND the valve’s current draw will not exceed 1 Amp, the valve
can be connected to the SUBM PUMP DRIVE line. Otherwise, it should be driven from the
external submersible starter relay. In all cases, the tank valve must operate at the same voltage
as the submersible pump.
11 If this unit is equipped for 230 VAC operation (international), wire as shown in the standard
115 VAC wiring layout diagram.
12 If this unit is equipped with a TopKAT option, there will be 10 wires in the junction box. See
The TopKAT Installation Manual for wiring requirements and information.
13 When multiple dispensers are used to control a common submersible starter relay or pump,
and the 9800 is controlled (authorized) through the “Control/SubM Feed” line (as in the case
of some fuel management systems), it is important that the lines from the 9800 to the
submersible equipment be isolated from each other. This can be accomplished by running the
submersible control lines through a secondary set of relay contacts in the fuel management
system. If a secondary set of contacts is not available, external control relays must be used
between the 9800 and the submersible starter relay or pump. Another option is to provide a
separate submersible starter relay for each hose outlet. In no case can the submersible drive
lines from the 9800 be tied together.
