187
Fault in fan 4
Failure in the 3rd external fan or the corre-
sponding tacho signal. The power is not re-
duced. This occurs via the temperature dereg-
ulation. All 3 LEDs light up on the device.
Is the fan blocked?
For electrically
trained and quali-
fied personnel: Are
the plugs correctly
plugged in?
E
188
Semiconductor test not pos-
sible
- Filter voltage measurement or actuation of
the semiconductors faulty. -AC filter can no
longer be discharged below 50V. - Possibly
there is a grounding problem or a faulty ad-
justment. - DC link is unbalanced.
Disconnect AC and
DC, wait 1 minute
and switch on again.
B
189
Semiconductor module 1 in
channel A defective
Semiconductor module x from channel A is de-
fective or the corresponding filter relay is not
closing correctly.
Disconnect AC and
DC, wait 1 minute
and switch on again.

195
DESAT error
Saturation monitoring (DESAT) of the IGBTs
has tripped or the voltage supply (24 V) of the
gate drivers is too low.

Protection shutdown grid
voltage (effective value) L1
Protective shutdown due to an excessively
high grid voltage on Lx. It is the effective value
which is decisive for the shutdown procedure.
Check the AC-side
wiring (e.g. in-
creased voltage due
to inductance ca-
pacity of a trans-
former) If the error
display occurs fre-
quently, or every
time, the installa-
tion must be
checked. If there is
nothing wrong with
the installation,
then there is a fault
in the device.
Check connection/
cabling!
