Relay
K1
ZK undervoltage
Intermediate circuit voltage below a fixed
limit for longer than 75 s.
ZK overvoltage
Intermediate circuit voltage above fixed
limit for longer than 75s.
Reason for excessively high line voltage
or alternator motor operation.
IGBT cooling down period
IGBT cooling down period for approx.
60 sec.
Communication fault
MODBUS communication interrupted
Line voltage too low
Line voltage below a fixed limit for longer
than 75 s.
Line voltage too high
Line voltage above fixed limit for longer
than 75 s.
Error Peak current
If the output current increases above the
specified limit (even in a short time-
frame) the device will switch-off.
Motor fault
A connected thermostat or thermistor
has tripped the circuit or interruption be-
tween both terminals "TB / TP".
Plug for "TB" or "TP" in wrong position.
Sine filter to hot
(only in version with integrated sine filter)

Diagnostics / Faults
Reaction of device
Adjustment
The modulation is switched off immedi-
ately at undervoltage, error message
after 75 s.
Automatic switching back on and switch-
ing off of error message when the volt-
age exceeds the fixed limit for at least 5
s.
Check line voltage.
The modulation is switched off immedi-
ately at overvoltage, error message after
75 s.
Automatic switching back on and switch-
ing off of error message when the volt-
age drops below the fixed limit for at
least 15 s.
Check line voltage.
Prevent generator motor operation.
Final shutoff after 2 cooling-off intervals

description MODBUS communica-
tion
The modulation is switched off immedi-
ately at undervoltage, error message
after 75 s.
Automatic switching back on and switch-
ing off of error message when the volt-
age exceeds the fixed limit for at least
5 s.
Check line voltage.
The modulation is switched off immedi-
ately at overvoltage, error message after
75 s.
Automatic switching back on and switch-
ing off of error message when the volt-
age drops below the fixed limit for at
least 15 s.
Check line voltage.
After a switch off the controller waits for
30 seconds then the controller attempt a
start.
If 10 switch offs take place consecutively
within 60 s (time to next respective
error), final switch off takes place with an
error message.
Should no further switch off be exceeded
in 90 sec. the counter will be reset.
The unit cuts out and does not switch on
again.
Check motor and connection then reset
( Motor protection).
Switch off at to high temperature, restart-
ing after cooling down.
Check temperature in controller, Check
cooling of the controller.
