ZK overvoltage
If the DC-link voltage increases above a
speci
fi
ed limit, the motor will switch off.
Reason for excessively high input voltage or
alternator motor operation.
If the DC-link voltage drops below the limit
within 75 seconds, then the cotroller will
attempt to start.
Should the DC-link voltage stay above the
limit for more than 75 seconds, the device
will switch off with a fault message.

Error motor start
If a starting command is given (enable avail-
able and Setpoint > 0) and the motor does
not start to turn in the correct direction with-
in 5 minutes, then an error message will
appear.
If it is possible to start the motor in the
target direction of rotation after the error
message, the error message will disappear
Should a voltage interruption occur in the
meantime, the time taken up to the switch
off will begin again.
Check if motor is freely rotatable.
Check if the fan is driven in reverse direction
by an air stream (
Behaviour in rotation
by air current in reverse direction).

interrupted
Line voltage too low
If the DC-link voltage drops below a speci-
fi
ed limit the device will switch off.
If the line voltage rises above a speci
fi
ed
limit within 75 seconds, then the controller
will attempt to start.
Should the line voltage stay below the
speci
fi
ed limit for more than 75 seconds,
the device will switch off with an error mes-
sage
13 x
de-energized, 11 - 14
interrupted
Line voltage too high
Cause to high input voltage
If the line voltage increases above a speci-
fi
ed limit, the motor will switch off.
If the line voltage drops below the speci
fi
ed
limit within 75 seconds, then the controller
will attempt to start.
Should the line voltage stay above the
speci
fi
ed limit for more than 75 seconds,
the device will switch off with an error mes-
sage.
14 x
de-energized, 11 - 14
interrupted
Error Peak current
If the motor current increases above the
speci
fi
ed limit (even in a short time-frame)
the device will switch-off.
After a switch off the controller waits for
5 seconds then the controller attempt a
start.
Arises within 60 sec. in series 5 further dis-
connections a
fi
nal switch off with fault indi-
cation follows.
Should no further switch off be exceeded in
60 sec. the counter will be reset.
17 x
de-energized, 11 - 14
interrupted
Temperature alarm
Excess of the max. permissible inside tem-
perature.
Controller switches off motor. Automatic re-
starting after cooling down.
Check installation of the device and cooling
of the controller.
