Diagnosis: Troubleshooting, Warnings and Alarm Codes
248
119
Digital Valve Error
• Occurs during pretrip (PTI) test only.
• Compressor Current consumption not correct for
valve position.
• Using Manual Function Test,
without
compressor and fans active check the function
of the valve by observing the sound or feel of
the valve while activating/deactivating.
• Using Manual Function Test, with compressor
and fans active check the function of the
valve.
• The current consumption during NOT
energized valve must be higher than during
energized position.
• With Condenser coil temperature above
35C the expected increase is min 0,9A and
below 35C expected limit is 1,5A.
120
Suction Pressure Sensor Error
• Occurs during Normal Run if the sensor is detected
to be out of range, open or short circuit.
• Occurs during pretrip (PTI) test if the sensor
readings do not act correct during compressor
activity.
• Expected to decrease 0,15Bar from stopped to
compressor running loaded.
• Indicates:
• Wrong location of the sensor.
• Sensor failure.
• Using DATA menu evaluate sensor readings.
• Check wiring to be correct and connected.
• Check J1 plug is plugged into MRB.
• Check voltage at J1 pin7 to be 0.5 – 4.5 volts.
• Replace sensor.
121
Discharge Pressure Sensor Error
• Occurs during Normal Run if the sensor is detected
to be out of range, open or short circuit.
• Occurs during pretrip (PTI) test if the sensor
readings do not act correct during compressor
activity.
• Expected to increase 0,15Bar from stopped to
compressor running loaded.
• Indicates:
• Wrong location of the sensor.
• Sensor failure.
• Using DATA menu evaluate sensor readings.
• Check wiring to be correct and connected.
• Check J1plug is plugged into MRB.
• Check voltage at J1 pin4 to be 0.5 – 4.5 VDC.
• Replace sensor.
122
O2 Sensor Calibration Error
• Occurs during AFAM+ PTI test.
• Occurs only if the setting O2 SENSOR USAGE is
ON.
• After ventilation if the O2 reading is below 17% or
above 25%.
• Indicates:
• Sensor lost the calibration.
• Failing sensor.
• Open doors and ventilate container.
• Redo the test.
• Recalibrate sensor.
• Replace the sensor.
