FAE Device Error
• Occurs during pretrip testing if the expected door
endpoints can’t be reached.
• Occurs during normal operation
• If the AFAM+ module isn’t detected.
• During door position calibration the expected
door endpoints feedback can’t be reached.
• During pulsing movement the expected door end
points feedback can’t be reached.
• Indicates:
• Stocked air vent. door motor.
• Failing or missing AFAM+ module.
• Inspect AFAM+ module connection to the
controller.
• Using STATES MENU / EXPANSION
MODULE to inspect the observed presence
and readings of the AFAM+ module.
• From backside left bay is bay 1
• From backside right bay is bay 2
If the module is not found use the tester to
decide the problem.
• Inspect wiring from AFAM+ motor to AFAM+
module.
• Using MANUAL FUNCTION TEST move and
Inspect air vent door movement.
• Inspect air vent.
• Replace AFAM+ motor.
58
Phase Sensor Error
• Occurs during pretrip (PTI) or function test only.
• During Phase Sensor Test, while direction is
reversed, the condenser fan and compressor is
tested.
• If the current consumption of the condenser fan
is below 0,5A on each phase.
• If the current consumption of the compressor is
below 2,0A on each phase.
• Indicates:
• Defective phase relay.
• Defective power module.
• Start a Manual Function Test. With reverse
phase direction selected, check the condenser
fan runs reversed direction and the
compressor is activated and makes loud
noise. Allow only for short time activation max.
5 sec.
59
Delta Current Error
• 100% ampere difference between current phases,
max reading must be above 1,5A.
• The alarm is protected by a timer which demand
the state to be present for 3 minutes before the
alarm is set.
• Indicates:
• Open connection on one phase of power supply
to a motor or heater element.
• Blown fuse.
• Enter Manual Function Test menu and test
(operate) each 3-phase component to locate
defective connection.
• Check fuses.
60
Humidity Sensor Error
• Occurs during pretrip (PTI) test.
• Relative humidity reading is less than 15%.
• Indicates:
• Sensor disconnected.
• Wrong controller software configuration, sensor
might be disconnected or removed.
• Defective sensor
• Check sensor connections.
• Check controller configuration menu for
correct humidity setting.
• Replace sensor.
