Control Lines
Page 4-4 MDE-4340A Series 9800Q Pumps and Dispensers Installation/Operation Manual · January 2006
Note: When multiple dispensers are used to control a common submersible starter-relay or
pump, and the 9800 is controlled (authorized) through the Control/Pump MotorFeed
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.
Submersible Pump Drive (SubM Pump Drive)
This line is always present for remote dispensers, but is active only when SubM drive relays
are supplied. The SubM drive is a 115/230 VAC (230 VAC Int'l) 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 will be controlling the same starter relay or
pump, they can be combined. This line is also used to control an external valve used on
aboveground tank installations.
Note: See Special Note in Submersible Starter Drive for situation where more than one hose
outlet will be using the same submersible pump.
Reset Complete (Switch Detect)/Slow Flow
The Reset Complete/Slow Flow is a 115 VAC (230 VAC Int'l) output which is used to indicate
that the reset process is complete and the unit is ready to dispense product, such as may be
required when used with a Fuel Management System (FMS). It may also be used to control a
remote (satellite) slow flow valve. Two lines are provided for twins.
In addition to the internal load of the slow flow valve, this line is capable of supplying 170 mA
AC maximum to the satellite valve and FMS. When connecting to a non-Gasboy satellite or
FMS, ensure that this limit is not exceeded. This line must not be shorted to any conduit or
chassis metal, mis-wired, used to control both stages of a satellite valve, or be connected to
equipment requiring more than 170 mA AC from this line to operate, or the CPU PC board
will be instantly damaged! This line must be left capped when not in use.
Follow the checks in “Pump/Remote Dispenser Operation” on page 6-1 before applying power
to avoid accidental damage.
Fast Flow
This is a 115 VAC (230 VAC Int'l) line that can be used to control a remote (satellite) fast
flow valve. Two lines are provided for twins. In addition to the internal load of the fast flow
valve, this line is capable of supplying 170 mA AC to the satellite valve. When connected to
a non-Gasboy satellite, ensure that this limit is not exceeded.
