EXV = Electronic Expansion Valve (errors related to this, AL07 to AL11, are due to other sensors that are required
from the valve to work correctly)

The current delivered by the inverter drive is too high, check the power supply, then try to restart
the system and reset the alarm. If the error does not go eway, contact the closest Climma service
center.
The current delivered has exceeded the rated motor current beyond the maximum time
allowed.
Shut off the system, wait 1 minute, then try to restart the system and reset the alarm. If the
error does not go eway, contact the closest Climma service center.
The DC voltage between the inverter and the compressor has exceeded the allowed limits.
There may be a voltage surges in the power supply, therefore check the power supply.
Shut off the system, wait 1 minute, then try to restart the system and reset the alarm. If the
error does not go eway, contact the closest Climma service center.
The DC voltage between inverter and compressor is below the allowed limits. This can be due
to insufficient power supply or maybe other circuit errors, so check also for other errors, then
shut off the system, wait 1 minute, then try to restart the system and reset the alarm. If the
error does not go eway, contact the closest Climma service center.
Drive temperature has exceeded the allowed maximum.
Inverter is water cooled so check that there is water flow in the cooling plate on the back of the
inverter.
If there is no flow, check the water valve on the system, which is allowing or not the water to
flow in the inverter cooling plate.
Drive temperature is lower than the allowed minimum.
Heat the environment where the drive is installed.
The current delivered by the inverter drive is too high; this can be due to a sudden significant
increase in
load or short-circuited motor cables.
Check the power supply and the cables to the motor, then shut off the system, wait 1 minute,
then try to restart the system and reset the alarm. If the error does not go eway, contact the
closest Climma service center.

Flow switch error. Low water in the
circulation circuit
Inverter is offline, shut off the power
supply and check the wiring diagram
and connections, then try to restart the
system and reset the alarm.
If the error does not go eway, contact
the closest Climma service center.
