Message Action needed
POWER FAILURE The power to the compressor unit has been turned off and back on.
Press [STOP/RESET] and select an operating mode.
SHORTED THERM The controller has detected a shorted connection to thermistor: (A)
airend discharge or (B) separator. This normally indicates a faulty
connection (e.g. wire strands touching) at the controller connector 7;
check and correct the connection. This could also be indicating a
damaged wire or thermistor probe.
SHORTED XDUCER Signal voltage has exceeded approximately 4.6 volts at transducer: (A)
final discharge or (B) reservoir. This may indicate a loose connection of
the black wire to the transducer or a defective transducer. Check
connections, or replace transducer if necessary.
WATER PRESS 120 volts has been removed from terminal 7 of the terminal strip. This is
normally shipped jumpered directly to terminal 9, but the jumper may be
removed to add a field installed shutdown switch. Reset the external
switch.
ZERO XDUCER Signal voltage has fallen too low at transducer: (A) final discharge or (B)
reservoir. This error is usually the result of the transducers being
improperly zeroed. Disconnect the air lines to the transducers and follow
the procedure indicated in the adjustment instructions. This shutdown
for transducer B may also be the result of reverse compressor rotation.
Check connections, or replace transducer if necessary.
