PACKAGED VERTICAL COMPACT UNITS
AIR-AIR
Should the DC-link voltage stay for more than 75
seconds below the limit, the device will switch off with
a fault message.
8x
de-energized, 11 - 14
interrupted
DC overvoltage
If the DC-link voltage increases above a
specified 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 controller 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.

IGBT cooling down period for
approx. 60 sec.
Final shutoff after 2 cooling-off intervals

Fault 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 within 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).
12x
de-energized, 11 - 14
interrupted
Line voltage too low
If the DC-link voltage drops below a
speci
fied limit the device will switch off.
If the line voltage rises above a specified limit
within 75 seconds, then the controller will attempt
to start.
Should the line voltage stay below the specified limit
for more than 75 seconds, the device will switch off
with an error message
13x
de-energized, 11 - 14
interrupted
Line voltage too high
Cause to high input voltage
If the line voltage increases above a
speci
fied limit, the motor will switch off.
If the line voltage drops below the specified limit
within 75 seconds, then the controller will attempt to
start.
Should the line voltage stay above the specified limit
for more than 75 seconds, the device will switch off
with an error message.
14x
de-energized, 11 - 14
interrupted
Error peak current
If the motor current increases above the
specified 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
final switch off with fault indication
follows.
Should no further switch off be exceeded in 60 sec. the
counter will be reset.
17x
de-energized, 11 - 14
interrupted
Temperature alarm
Excess of the max. permissible inside
temperature.
Controller switches off motor. Automatic restarting
after cooling down.
Check installation of the device and cooling
of the controller.
* K1: function programmed by manufacturer: error message not reversed.
