LINE EQUIPMENT FAULT ALARM (Ver. 19 and Higher)
The pressure monitors have determined that there is a fault with
the pressure measurement system.
Probable Causes:

2. Faulty PLLD Interface Module.
3. Mis-wired transducers.
Troubleshooting Guidelines:
1. Turn Off power to the STP - WARNING! The pump must
remain Off for steps 2, 3, and 4 below..
2. Vent the product line to drop the line pressure to zero.
3. Reconnect the product line.
4. Restore STP power.
5. In the PLLD/WPLLD diagnostic menu, run the pressure mea-
surement offset test.
WARNING!: WPLLD turns On the pump to make a pres-
sure measurement. Make sure the line is reconnected
before running the test.
6. If the test result is greater than 5 psi, check the transducer wir-
ing. If the wiring is correct replace the transducer.
7 Following all repairs re-run the pressure measurement offset
test.
