Active temperature management
The device has an active temperature
management to protect it from damage
due to too high inside temperatures. In
case of a temperature rise above the
fixed limits, the modulation is reduced
linearly. To prevent the complete system
being switched off externally (in this
operation permissible for the controller) in
case of reduced operation due to too high
an internal temperature, no fault message
is sent via the relay.
With a drop in temperature the modulation rises again llinear.
Check cooling of the controller
3 x
de-energized,
11 - 14 inter-
rupted
HALL-IC
Incorrect signal from the Hall-ICs,
error in the commutation.
Internal plug connection faulty
The controller switches the motor off.
Automatic restart if no faults are recognised.
Replace fan / motor

Line failure (only for 3 ~ types)
The device is provided with a built-in
phase-monitoring function for the mains
supply. In the event of a mains interrup-
tion (failure of a fuse or mains phase) the
unit switches off after a delay (approx.
200 ms).
Only functioning with an adequate load
for the controller.
Following a shutoff, a startup attempt is made after approxi
-
mately 15 seconds, if the voltage supply is high enough. This
keeps occurring until all 3 supply phases are available again.
Check power supply
5 x
de-energized,
11 - 14 inter-
rupted
Motor blocked
If after 8 seconds of commutation no
speed is measured > 0, the fault “Motor
blocked” is released
EC-Controller switches off, renewed attempt to start after about
2.5 sec.
Final shutoff, when fourth starting test fails.
It is then necessary to have a reset by disconnecting the line
voltage.
Check if motor is freely rotatable.

de-energized,

rupted
IGBT Fault
Short circuit to earth or short circuit of the
motor winding
EC-Controller switches off, renewed attempt to start after about
60 sec.
Code 9.
Final shutoff, if - following a second starting test – a second fault
detection is detected within a period of 60 seconds.
It is then necessary to have a reset by disconnecting the line
voltage.

de-energized,
11 - 14 inter-
rupted
DC undervoltage
If the DC-link voltage drops below a spec-
ified limit the device will switch off
If the DC-link voltage rises above the limit within 75 seconds,
then the cotroller will attempt to start.
Should the DC-link voltage stay for more than 75 seconds be-
low the limit, the device will switch off with a fault message.
8 x
de-energized,
11 - 14 inter-
rupted
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 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.

IGBT cooling down period
IGBT cooling down period for approx.
60 sec.
Final shutoff after 2 cooling-off intervals Code 6

Fault motor start
If a starting command is given (enable
available 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 rota-
tion 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)
12 x
de-energized,

rupted
line voltage too low
If the DC-link voltage drops below a spec-
ified limit the device will switch off
If the line voltage rises above a specified limit within 75 sec

Should the line voltage stay below the specified limit for more
than 75 seconds, the device will switch off with an error mes

Line voltage too high
Cause to high input voltage
If the line voltage increases above a
specified limit, the motor will switch off
If the line voltage drops below the specified limit within 75 sec
-
onds, 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 mes
