Cause
Remedy
The diaphragm tank is faulty.
Check for a properly installed diaphragm tank. Has the
tank failed? Has the tank been charged to the proper
operating pressure before installation? (~10 psi below
the desired set point)
The pressure transducers are faulty.
Check the pressure transducers. Does the actual
mechanical gauge pressure match the pressure
displayed on the VFDs and the PLC?
A check valve is malfunctioning.
Check for malfunctioning check valves. Replace faulty
valves.
There is an error in the PLC programming.
Check the customer programming on the PLC. Correct
any errors.
