Return to the Diagnostic Mode, by pressing the MODE key until this message appears:
Press the FUNCTION key until this message appears:
Press the STEP key to view the pump status. Because a passing line test has not been run, the line status will be disabled
and you should se the message:
In the display shown, W = device code for WPLLD, X = line number, Product Label = name assigned to product in tank
setup, and Dispensing Disabled = current line status.
Press ENTER to run a 3.0 gph line test. During the “Running Pump” state, verify that the Pump On pressure is within the
range 22 - 60 psi then drops to within the range 18 - 26 psi during the “Test 3.0” and “Test Complete” states:
If there is not at least a 2 psi difference between the Pump On pressure and the Pump Off pressure, a no-venting
condition exists that will interfere with precision line testing. Please consult the WPLLD Alarm Quick Help guide’s
“Periodic or Annual Test Needed Warning” discussion for troubleshooting information.
Check for STP leaks as follows:
a. Turn On the STP and carefully check all fittings and the functional element for leaks.
b. Verify that the functional element, strainer, and check valve threads into the pump are not leaking.
IMPORTANT! The WPLLD does not perform any leak test on the functional element or any other components
upstream from the check valve and will not detect leaks there.
c. Tighten any leaking fittings until the leak is stopped. Be careful not to overtighten and strip the threads.
d. If the leak cannot be stopped, turn Off, tag, and lock out power to the submersible and check the fitting for thread
damage or improper sealing. Replace or reseal the fitting as required.
Checking the Site’s Emergency Stop Switch
After the WPLLD system is installed and all lines are enabled for dispensing, test the site to ensure that the Emergency
Stop switch will shut down the pumps for all lines.
1. Turn On power to the TLS Console.
2. Engage the Emergency Stop switch. Dispensing from all lines should stop immediately. If the pumps do not stop,
rewire the Emergency Stop switch circuit.
