OFF
de-energized, 13 -

No line voltage
In the event of a mains interruption the
unit switches
“
OFF
”
and automatically
“
ON
”
when the voltage has been re-
stored.
Check line voltage and pre-fusing.

Temperature management active
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
fi
xed limits, the modulation is reduced
linearly. To prevent the complete system
being switched off externally (in this op-
eration 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 modula-
tion rises again llinear.
Check cooling of the controller.

de-energized, 13 -
14 interrupted
line failure
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.
15 s).
Only functioning with an adequate load
for the controller.
Following a shutoff, a startup attempt is
made after approximately 5 seconds, if
the voltage supply is high enough. This
keeps occurring until all 3 supply phases
are available again.
Check line voltage.

14 interrupted
IGBT Fault
Earth fault or short-circuit at inverter out-
put.
The device switches off, renewed at-
tempt to start after about 60 s
Code 9.
Final switch off when error is detected
after the third start attempt at an interval
< 60 s.
Reset by enable or line voltage ON/OFF.
