Theory of Operations
Detailed descriptions of the various operations, control buttons, and LED indicators that make up the
control panel are listed below.
IMPORTANT NOTE:
THERE IS A 5 SECOND DELAY REQUIRED BETWEEN
PRESSING THE START AND FILL BUTTONS, IF THEY ARE
PREESED SOONER THERE WILL BE 3 SECOND DELAY
BEFORE THE PUMP WILL OPERATE.
Fill Operation:
•
When the FILL button is pressed and released and the fuel tank is not full, the motor starts the
pump in the fill direction. The FILL button does not need to be held.
•
The pump will also stop while filling at the instant the fuel dial reads full. If the FILL button
is pressed and held, when the fuel level reads full, the pump will run. The pump will run in
the fill direction until the FILL button is released.
•
The voltage to the pump motor is approximately 12 VDC whether the unit is operating from a 12
VDC battery or a 24 VDC battery.
•
Whenever the pump is operating in the Fill direction, the DOWN ARROW LED (away from
the truck) is illuminated.
•
If the pump is operating in the Cleaning (Run) direction the FILL button is ignored.
Cleaning (Run) Operation:
•
When the START button is pressed and released, and the FUEL LEVEL shows at least 1/8 tank,
the motor will start the pump in the Clean (Run) direction. The timer dial will show the total
Clean run time. The default total Clean time is 45 minutes. Refer to the Timer Operation section
for operation of the timer buttons.
•
The FUEL PRESSURE can be monitored by observing the fuel pressure gauge on the top of the
cabinet. Do NOT exceed 100 psi.!
•
Whenever the pump is operating in the clean direction the UP ARROW LED (towards the
truck) is illuminated.
•
If the pump is operating in the Cleaning direction and the FUEL LEVEL dial shows empty (the
empty “E” LED is illuminated) for at least 5 consecutive seconds, the total cleaning cycle time will
be completed and the CYCLE COMPLETE LED on the timer dial will be illuminated. The pump
will continue to operate. The SYSTEM WARNING LED will flash and the alarm will sound
continuously until the STOP button is pressed. If the STOP button is not pressed the pump and
alarms will automatically shut off after 5 minutes.
•
The voltage to the pump motor is approximately 12 VDC whether the unit is running from a 12
VDC battery or a 24 VDC battery.
