123 Datalogger Battery Error
• In cold ambient if the battery heater (battery
internal) is not capable of heating up the battery,
ready for charging within 2 hours.
• If the battery is not connected.
• If the battery voltage is below 3,0VDC.
• Using DATA menu to determine the state of
the battery. Evaluate temperature and voltage.
• Check the battery physically, dismount and
examine wires and the connection to the
controller.
• Replace battery.
124 Cold Treatment Restart
• Occurs during Normal Run and only with cold
Treatment active.
• Only active with the surveillance active (OOCL
option).
• Indicates:
• Cold treatment period is restarted due to
temperatures.
• Problem with cooling process,
• Too long duration of power off.
• Unit will automatically restart the treatment
period.
127 Alarm General Unit Error
• The surveillance has determined that the unit is not
capable of continue running, and has shut down.
• The reason is displayed at the controller main
screen, and is stated at the event next to the alarm
event.
• Known reason to the shutdown state is:
• “SET POINT OUT OF RANGE”
• “VOLTAGE OUT OF RANGE”
• “POWER LINE PHASE ERROR”
• “REGULATION PROBE ERROR”
• “COMPRESSOR TEMPERATURE HIGH”
“SET POINT OUT OF RANGE”
• The temperature set point is outside valid
operation range. +30°C to -40°C (+35°C with
extended range).
• Check configurations and settings on the
controller.
“VOLTAGE OUT OF RANGE”
• The measured voltage is below 330VAC.
• Check power line voltage while loaded.
“POWER LINE PHASE ERROR”
• The phase detection system detects phase
error or not capable of securing the correct
rotation.
• Check power line voltage and quality.
“REGULATION PROBE ERROR”
• If supply and return air temperature sensor
and evaporator coil temperature sensors ALL
indicate OPEN or SHORT circuit, the software
is not capable of determine a reasonable
action related to the cargo.
• Follow steps related to the sensor alarms.
“COMPRESSOR TEMPERATURE HIGH”
• The compressor temperature is measured to
be above 148°C. The state will stay until
compressor temperature is measured to be
below 132°C.
• Check refrigerant level and flow through the
cooling circuit.
