LS-500 Alarms and Warnings
Alarms During the Learn Process
Alarm Symptom Possible Cause Resolution
Failed to pressure up STP is not turning on Verify that the 4-20 transducer is
a relay / TPI input
Check the programming
Is the pump controller powered
on?
Check the controller
If controlled by a relay, is the
common of the relay wired to 110
Volts?
Test the voltage on the relay
common
Is another STP turning on? Check the other STPs
STP is turning on, but
the LS500 doesn’t see
the pressure change
Is the 4-20 transducer in alarm? Check alarms
Is the wrong transducer
mapped?
Check programming
Is the clamp valve down? Look at the pressure gauge on
the needle valve kit for operating
pressure
Line is not
configured
Program mapping error Verify programming
Program error
detected
Console software error Reboot console
Air in line Console has sensed line
pressure variations
Investigate, then Purge Line Starting

Insufficient volume Line is too small
Leak generator not correct
Air in the line
Check line size
Review leak generator set-up

Pressure was less
that 12 psi after
programmed delay
when STP turned on
Clogged STP intake Investigate, force a manual test
and observe pressure

programmed as an input for the
relay / TPI.
