Diagnosis: Troubleshooting, Warnings and Alarm Codes
251
131 Ambient Condenser Temperature Probe Error
• Occurs during pretrip (PTI) test and probe test only.
• After ventilation with the condenser fan.
• If the ambient air and condenser coil temperature
sensor readings differs more than 2.5C.
• Indicates:
• Failing sensors.
• Misplaced sensors.
• Failing controller.
• Use the DATA menu to detect the failing
sensor.
• Replace sensors.
• Use the tester to determine the problem.
132 Power Module Sensor Error
• The surveillance continually evaluates the
measurements reported by the power module.
• The surveillance includes a timer with a timeout at
60 seconds before the alarm is set.
• Indicates:
• Power module located readings outside allowed
range.
• Use DATA menu to determine the failing
reading.
• The accepted limit for
• Line AC voltage is 180 to 700VAC.
• Power line current is 0mA to 32A.
• Radiator temperature is -100C to 200C.
• Check for latest software revision.
• Use tester to determine the problem.
133 Power Module Network Error
• The surveillance has not received valid status
communication from the power module for 10
seconds.
• Indicates:
• Communication problem.
• Check connection between controller and
power module.
• Use tester to determine the problem.
134 Controller Error
• The surveillance has determined the state
“controller internal error”.
• Indicates:
• The controller is failing one way or another.
• Use the tester to determine the problem.
135 Power Module Error
• The surveillance has determined the state “Power
module error”.
• Indicates:
• The power module is failing one way or another.
• Use the tester to determine the problem.
136 Transducer Circuit Error
• The controller is not capable of generating the
expected voltage for the 12V transducer sensors,
(suction pressure and discharge pressure, AVL and
humidity sensor).
• Replace Data logger Battery.
• Use the tester to determine the problem.
