S3 Fault Descriptions
2.0 Faults
An Intellisys S3 – A
WARNING
will not shutdown the compressor. The warning will
remain on the display until acknowledged. It can be cleared by pressing the “C” clear key. A log will
be retained of the warnings / trips that have occurred. An Intellisys S3
TRIP
will shutdown the
compressor and must be manually cleared by pressing the “C” clear key. The trips will remain on the
display until acknowledged. The trips displayed will take precedence over the warnings. A log will be
retained of the warnings / trips that have occurred.
Trip Faults Comments
ENH Motor Reverse Rotation
- Sump pressure has not indicated a positive pressure, 2 seconds
after the machine has loaded, first time after a power-up. This time is increased to 6 seconds if the
soft starter option is turned on. Once correct motor rotation is verified, this is not checked again until
power is removed from the controller.
STD Emergency Stop
- Emergency Stop low level contact has opened.
STD Motor Overload
- Main motor or Fan motor Overload contact has opened.
STD High Package Discharge Pressure
– refer to table in section 12 - (Not Adjustable, Information
Only)
STD High A/E Discharge Temperature
- refer to table in section 12 - (Not Adjustable, Information
Only)
STD Low Ambient Temperature
- The air-end temperature sensor is measuring a temperature less
than 2°C. The compressor will be in an alarm state and not start if the temperature is below 2°C. The
compressor will start if the temperature is above 2°C. This is only active if Low Ambient, LA, option is
installed.
ENH Low Sump Air Pressure
- The sump air pressure has not increased above 15 psi. This is
measured 15 seconds after starting and operational anytime the compressor is running.
ENH High Sump Air Pressure
- refer to table in section 12 (Not Adjustable, Information Only)
STD Discharge Pressure Sensor Failure
- The discharge pressure sensor input reading is beyond
the normal measurement range below 3.4 ma or above 20.8 ma.
ENH Sump Pressure Sensor Failure
- The sump pressure sensor input reading is beyond the
normal measurement range below 3.4 ma or above 20.8 ma.
STD
/
ENH Sensor Calibration Failure
- A sensor calibration has been attempted and the measured
value is outside of the +/- 10 % Full Scale value.
ENH Motor PTC Trip
The motor TC is open due to high motor Temperature.
