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.
