ADVISORY TROUBLESHOOTING GUIDE
All advisories are indicated on the keypad by a yellow indicator in the Status area, and one of the following messages
alternating with the normal lower line display. Perform service or maintenance as indicated, then clear the advisory
as instructed in Section 4.
Message Action Needed
CHECK COMM PORT The controller has detected a communications problem while running in Sequence
mode. Check for proper cable installation. If the controller switches from Se-
quence to Auto mode, reprogram a different unit number.
CHNG AIR FILTER Excessive vacuum has been detected after the air filter, indicating it has become
full. Change the air filter to ensure maximum air delivery.
CHNG SEPARATOR The differential pressure across the separator has risen to over 8 psid. Change
the separator to ensure peak compressor performance.
CHNG OIL FILTER The unit has been operated for the programmed number of hours since the last
filter replacement. Change the filter to ensure an adequate flow of lubricant.
CHANGE OIL The unit has been operated for the programmed number of hours since the last
oil change. Change the oil to ensure lubricant quality.
HIGH DISCH TEMP The temperature was greater than 210 degrees F (99 degrees C) at the airend dis-
charge. Ensure that the compressor receives adequate cooling air or water, and
that the coolers are not plugged.
HIGH MOTOR AMPS The unit has been operated with motor current in excess of the programmed ser-
vice factor amps. Turn valve units will unload during moderate overcurrent to pre-
vent sustained operation.
HIGH RES TEMP The temperature was greater than 210 degrees F (99 degrees C) at the separator.
Ensure that the compressor receives adequate cooling air or water, and that the
coolers are not plugged.
LOW AMB TEMP The temperature was less than 40 degrees F (4 degrees C) at: (A) the airend dis-
charge, (B) the separator. Ensure that the compressor is located in a room kept
above freezing.
