SHUTDOWN TROUBLESHOOTING GUIDE (Continued)
Message
Action Needed
MAIN STARTER
The controller has attempted to start the compressor, but did not receive a re-
turn signal from the starter’s auxiliary contact. If the starter does not pick up
when attempting to start, check that connector 9 of the controller is plugged in
firmly, and check the starter coil. If the starter does pick up, but this message
appears, check that the auxiliary contact block is properly installed on the start-
er and wired to connector 8, terminal 4.
MAIN STRT CONTCT
The controller has attempted to turn off the compressor, but is still receiving a
return signal from the starter’s auxiliary contact. Check that the starter oper-
ates freely and that the contact block is properly installed on the starter.
OPEN AMP SENSOR
The controller is not sensing current to the main motor when it is turned on.
Check that the main starter is operating properly. Check for a loose or broken
connection at connector 4. Check wiring and proper installation of the current
transformer and current transducer. If not installed, set the “MOTOR SFA” to
zero amps in the configuration adjustments.
OPEN THERM
The controller has detected an open connection to thermistor: (A) airend dis-
charge or (B) separator. This normally indicates a loose or broken connection
at the controller connector 7; check and correct the connection. This could also
be indicating a broken wire or thermistor probe, or exposure to excessively low
temperatures.
OPEN XDUCER
Signal voltage has fallen too low at transducer: (A) Final discharge or (B) Res-
ervoir. This probably indicates a loose connection of the red or green wire to
the transducer or an unplugged transducer. It connections are good, this is indi-
cating a defective transducer. Check connections, or replace transducer if nec-
essary.
PHASE RELAY
120 volts has been removed from terminal 7 of the terminal strip. This is nor-
mally shipped jumpered directly to terminal 9, but the jumper may be removed
to add a field installed shutdown switch. Reset the external switch.
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 dis-
charge or (B) separator. This normally indicates a faulty connection (e.g. wire
strands touching) at the controller connector 7; check and correct the connec-
tion. 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 nor-
mally 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) Res-
ervoir. 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 re-
place transducer if necessary.
