Pump/Remote Dispenser Operation
Operating Sequence
The exact sequence of events that occurs during the operation of the pump or remote dispenser
is determined by various switch settings, inputs, and the user. A typical transaction is
explained below.
Pump
1 Turn on the pump handle. If AC is present on the Control Feed line, the reset cycle begins. The
display:
• goes blank for one second
• shows all 8s for one second, 3 seconds for US Gallons or SW1-5 enabled.
• goes to 0.000 (gallons) or 0.00 (liters) and remains for one (1) second.
• 9850Q goes to 0.00 (gallons) or 0.0 (liters) and remains for one (1) second or three (3)
seconds for US Gallon or if SW1-5 is enabled.
The pump motor turns on and the Reset Complete line becomes active. If equipped, the slow
flow valve turns on.
2 The user begins to dispense fuel. Quantity is not be recorded on the display until 0.010 gallons
(0.04 liters) are reached, however, all pulses are sent out on the Pulser line, if equipped. At
0.010 gallons (0.04 liters), the fast flow valve turns on, if equipped.
For 9850Q, quantities are not be recorded on the display until 0.04 gallons or 0.1 liter.
3 The pump continues to run until one of the following conditions occurs. These conditions turn
off all relays.
• The handle is turned off.
• The Control Feed line is turned off.
• A pulser error is detected.
• A timeout of 255 seconds is reached (if SW2-4 is CLOSED). If connected to a Fuel
Management System, the timeout loaded into the system will be used.
• A quantity of 990.000 gallons (9900.00 liters) is reached. If connected to a Fuel
Management System, the limit set in the system will be used.
• For 9850Q: A quantity of 999.00 gallons or (9999.0 liters) is reached. If connected to a
Fuel Management System, the limit set in the system will be used.
• The pump is halted by an operator of a Fuel Management System.
• An AC power failure occurs.
4 The 9800Q continues to monitor for pulses until a 2-second period with no pulses occurs. At
this time, the transaction is considered completed.
Remote Dispenser
1 Turn on the pump handle. If AC is present on the Control Feed line, the reset cycle begins and
the submersible pump turns on. The display:
• goes blank for one second.
• shows all 8s for one second or 3 seconds for US Gallons or if SW1-5 is enabled.
• goes to 0.000 (gallons) or 0.00 (liters).
• 9850Q goes to 0.00 (gallons) or 0.0 (liters) and remains for 1 second or 3 seconds for US
Gallons or if SW1-5 is enabled.
The slow flow valve will turn on within 2, 3, or 4 seconds, depending on the setting of the
Time Delay switches on the CPU PCB. This will give a total time of 4, 5, or 6 seconds
between the time the submersible pump turns on and the time the slow flow valve turns on.
