181
Insulation error, centre
Insulation error close to the centre of the PV
string (area co-15% of the half of the
string)
As such, symmetri-
cal fault resistances
are also detected.
These must be recti-
fied in order to op-
erate the system
safely and reliably.

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.
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.
