15. TESTING THE SYSTEM:
-
Carefully review all work completed, being sure all mechanical joints are thoroughly
tightened and electrical connections sealed.
-
Open the product crash valves and restore power to the dispenser.
-
With the power on, but no nozzles authorized, the VP1000 should not be running
(unless the ambient temperature is below 40°F), but the power LED (yellow) should be
energized on the interface module.
-
Authorize one handle and the vacuum system should activate when the gasoline flow
control valve is engaged. Repeat for all other nozzles, individually testing each nozzle
on each side of dispenser. With each authorization, one of the green LED’s on the
interface module should illuminate and the VP1000 activate.
-
Authorize one nozzle and listen to the speed of the VP1000. With only one nozzle
activated, the speed will be slower than if a nozzle on each side is activated. Activate
a nozzle on the other side of the dispenser and listen for the speed to change.
-
To test the tightness of the vapor plumbing installed on the suction side of the system
requires a 0-100” water column gauge. Connect the gauge into the 1/4” test port of
the reducing tee installed earlier in section 10 Photo L. Continue by following and
completing the START-UP / NEW INSTALLATION / WARRANTY / ANNUAL TESTING
FORM.
16. TROUBLESHOOTING THE VP1000:
Use extreme care and caution when performing the tests listed below. If 120 VAC is
accidentally applied to the fault or DC terminals, the module will be destroyed.
With power applied to the dispenser, but no products authorized, there should be 120
VAC between neutral and 120 VAC on the module terminal strip.
As above, with any product authorized, there should be single speed power applied to
the VP1000. Verify this by checking for 2-3 VDC from OUTPUT 1 (RED WIRE) to
FAULT COMMON (ORANGE WIRE), (or from OUTPUT 2 TO FAULT COMMON) also;
one GREEN LED should be illuminated. With a second product authorized on the
opposite side of the dispenser i.e. one product on each side, the motor should
operate at higher speed and there should be 2-3 VDC on both output 1 and 2 (to fault
common) and both GREEN LED’s should be illuminated.
With the pump running, a fault can be simulated by shorting, with a jumper wire, the
“FAULT INPUT” (purple wire) to FAULT COMMON (orange). This should cause the
motor to shut off, the solenoid valves to lose power and the dispenser to shut down.
Also, as long as the short is maintained, the red LED will be illuminated. Removing
the short will not automatically reset the module. To reset the module, remove the
short, remove power to the dispenser for twenty seconds and restore power. The
module should now be reset and the red led extinguished. This can also be
accomplished by using the power reset (PWR RESET) on the module.
