Operating Sequence for Series 9800 Only
The exact sequence of events that occur 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 Unit - Motor and Pump in Unit Base
1 Turn on the pump handle. If AC is present on the AUTH/Control Feed line, the reset cycle
begins. The display (electronic units):
• Goes blank for one second if 0 Delay Time is set, or for 4-6 seconds depending on the
setting Delay Time is set to.
• Shows all 8s for one second [three seconds for US Gallons or if JP5 (or SW1-5 for older
CPU boards) is set].
• Goes to 0.000 (gallons) or 0.00 (liters) until fuel starts.
The pump motor switches on and the Reset Complete line becomes active.
2 The pump continues to run until one of the following conditions occur. These conditions
switch off all relays as follows:
• The handle is turned off.
• The AUTH/Control Feed line (AC power line to pump/dispenser) is switched off by the
POS.
• A pulser error is detected (electronic units only).
• A time-out is reached (if the unit is programmed with a time out value). If connected to a
fuel management system, the time-out loaded into the system is used (commercial
electronic only). The unit turns off if it is idle for a preprogrammed time when no fuel is
flowing.
• A quantity of 990.000 gallons (9900.00 liters) is reached. If connected to a fuel
management system, the limit set in the system is used.
• The pump is halted by an operator of a fuel management system.
• An AC power failure occurs.
• Station Emergency Stop button is pressed.
Dispenser Units - Fueling Unit with No Motor and Pump in the Bottom
1 Turn on the pump handle. If AC is present on the AUTH/Control Feed line, the reset cycle
begins and the submersible pump switches on. The display (Electronic Unit):
• Goes blank for one second.
• Shows all 8s for one second [3 seconds for US Gallons or if JP5 (or SW1-5 for older CPU
boards) is set].
• Goes to 0.000 (gallons) or 0.00 (liters) and remains until fueling begins.
The display (mechanical units)
• Resets to 0.000 (gallons) or 0.00 (liters).
2 The user begins to dispense fuel.
3 The remote dispenser continues to run until one of the following conditions occurs. These
conditions turn off all relays as follows:
• The handle is turned off.
• The AUTH/Control Feed line is turned off (AC power line to pump/dispenser) is turned
off at the POS.
