Press ENTER and the results of the last test displays (‘No Test Data Available’ message appears if this is the first test):
Press STEP:
To start the test, press ENTER. During the test this message appears:
The Pressure Offset test results message appears when the test ends:
You can print out the test result if you have an optional printer. If you do not have a printer, record the offset value for the
transducer. Press TANK/SENSOR and repeat the above procedure for the each of the other WPLLD transducers.
The maximum offset pressure range is ±5 psi. If the Pressure Offset is greater than ±5 psi, repeat the test. If the Pressure
Offset is again out of range, either the line pressure is not completely vented or there is a hardware problem. Refer to
WPLLD troubleshooting procedures for further instructions.
Entering the Pressure Offset Value for each Transducer
Press MODE to return to the SETUP MODE, then FUNCTION until you see the message:
Press STEP until you see the message:
Press CHANGE and enter the Pressure Offset value for transducer W1. If necessary, press the left arrow key to change
the sign (+ or -). Note: enter the Offset value exactly as displayed in the Offset test result message (inc or - sign).
Press TANK/SENSOR, to display another transducer. Press CHANGE to enter its Pressure Offset value, then ENTER to
confirm the change. Repeat this procedure until you have entered Offsets for all transducers.
PURGE AIR FROM THE LINE
Follow accepted procedures to purge all air from the product line being enabled for dispensing.
ENABLE THE LINE FOR DISPENSING
After installing the WPLLD system, the TLS Console will not enable dispensing from a line until a 3.0 gph test on the
line has been passed. In this step, as you run the required 3.0 gph test, you will also verify that the Pump On and Pump
Off pressures are within their proper operating ranges.
IMPORTANT! Verify that the functional element and SwiftCheck valve threads into the pump are not leaking. The
WPLLD system will not detect leaks upstream from the SwiftCheck valve, including a leaking functional element.
