Control carried out via a LAN
type network LAN control
The Airlogic is in remote
control mode, internal
regulation and receives a
remote emptying command. Manual Unload
The regulator is starting the
motor but cannot yet give the
signal to the Airlogic
concerning motor speed. Motor starting

Fault code Fault Possible cause Correcting measures
1 Overcurrent Frequency converter has detected
too high a current (>4*In) in the motor
cable:
•
sudden heavy load increase
• short circuit in motor cables
• unsuitable motor
Check loading. Check motor size.
Check cables.
2 Overvoltage The DC-link voltage has exceeded
the limits defined in table 4.2 (NX
manual)
• too short a deceleration time
• high over voltage spikes in supply
Make the deceleration time longer.
3 Earth fault Current measurement has detected
that the sum of motor phase current
is not zero.
• insulation failure in cables or
motor
Check motor cables and motor.
5 Charging switch The charging switch is open, when
the START command has been
given.
• faulty operation
• component failure
Reset the fault and restart. Should the
fault re-occur, contact the distributor
near to you.
6 Emergency stop Stop signal has been given from the
option board.
7 Saturation trip Very high overload. Defective
component Cannot be reset from the keypad.
Switch off power. If this does not help,
contact the distributor near to you.
8 Unknown fault The frequency converter
troubleshooting system is unable to
locate the fault. Reset the fault and restart. Should the
fault re-occur, contact the distributor
near to you.
9 Undervoltage DC-link voltage is under the voltage
limits.
• most probable cause: too low a
supply voltage
• frequency converter internal fault
In case of temporary supply voltage
break, reset the fault and restart the
frequency converter. Check the
supply voltage. If it is adequate, an
internal failure has occurred. Contact
the distributor near to you.
