ZK undervoltage
Intermediate circuit voltage below a
fi
xed
limit for longer than 75 s.
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
fi
xed limit for at least 5
s.
Check line voltage.

ZK overvoltage
Intermediate circuit voltage above
fi
xed
limit for longer than 75s.
Reason for excessively high line voltage
or alternator motor operation.
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
fi
xed limit for at
least 15 s.
Check line voltage.
Prevent generator motor operation.

Line voltage too low
Line voltage below a

after 75 s.
Automatic switching back on and switch-
ing off of error message when the volt-

75 s.
Automatic switching back on and switch-
ing off of error message when the volt-

Error Peak current
If the output current increases above the
speci
fi
ed limit (even in a short time-
frame) the device will switch-off.
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),
fi
nal switch off takes place with an
error message.
Should no further switch off be exceeded
in 90 sec. the counter will be reset.

Motor fault
A connected thermostat or thermistor
has tripped the circuit or interruption be-
tween both terminals
“
TB / TP
”
.
Plug for
“
TB
”
or
“

”
in wrong position.
The unit cuts out and does not switch on
again.
Check motor and connection then reset
(
Motor protection).
