Table 4: Controller Faults (indicated on the controller)
CAUSE
Emergency stop button has
been pressed.
Blower is blocked, damaged or
blower motor is faulty.
Compressor operating above
rated pressure.
Low coolant level.
High ambient temperature.
Insufficient cooling air.
Dirty, blocked coolant cooler
(cooling air side).
Blower motor direction of
rotation incorrect.
Controller software has been
changed.
Remote start button is pressed
after compressor is running or
remote start button remains
closed.
Remote stop button remains
open and either start button is
pressed.
Sensor is missing or faulty.
Insufficient cooling taking place.
A fault has occurred.
Calibration done with pressure
in compressor.
System leak.
Minimum pressure check valve
faulty.
Blowdown valve faulty.
Loss of control power.
Drive system fault.
Faulty pressure transducer
measurement.
Moisture separator condensate
drain trap faulty.
Separator element dirty or
blocked.
Loss of outputs of control power. Check controller outputs (110V AC) power supply (fuses/
Loss of control power.
Sump pressure too high.
Faulty motor or Airend.
REMEDY
Identify reason why, repair fault, disengage button and
reset controller.
Remove blockage, repair or replace damaged
components.
Check and modify settings. Review system requirements
and contact your local Ingersoll Rand representative.
Check for leaks. See also 'discharge air is contaminated
with coolant' . Top up coolant.
Review installation and system parameters.
Check ducting and cooling air path.
Clean or replace.
Wire correctly.
Recalibrate all sensors and check setpoints.
Check operation of buttons or operating procedures.
Check operation of buttons or operating procedures.
Install, repair or replace faulty sensor.
If compressor is watercooled or sea watercooled, check
that the cooling water is flowing. Check that there is no
air in the water cooling system. Check that the strainer is
not blocked.
Repair fault / reset controller.
Depressurize and re calibrate with pressure pipe to
sensor disconnected. If fault still exists, replace pressure
transducer.
Located and repair.
Repair with service kit.
Repair with service kit.
Check 110V circuit breaker.
Check wiring.
Check contactor KM1.
Contact your local Ingersoll Rand representative.
Calibrate and validate the wet sump and package
discharge transducers.
Ensure condensate drain system is functioning
properly, and condensate is being drained. See Table 4:
Troubleshooting Chart.
Change separator element.
