Line over-
voltage
13
de-energized, 13 -
14 interrupted
Line voltage too high
Line voltage above
fi
xed limit for longer
than 75 s.
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 voltage
drops below the
fi
xed limit for at least 15
s.
Check line voltage.
Peak current
14
de-energized, 13 -
14 interrupted
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
15
de-energized, 13 -
14 interrupted
Motor fault
A connected thermostat or thermistor
has tripped the circuit or interruption be-
tween both terminals
“
TB / TP
”
.
Plug for
“
TP
”
or
“
TP
”
in wrong positions.
The unit cuts out and does not switch on
again.
Check motor and connection then reset
(
Motor protection).
Output

Switch off at to high temperature, restart-
ing after cooling down.
Check temperature in controller, Check
cooling of the controller.
Overload
17
de-energized, 13 -
14 interrupted
Overload fault
The controller was switched off by the
current limitation.
The error is set after detecting 4 times
(I
2
t-process; maximum overload applied
for 60 s).
After every detection (IGTB Recovery
Flag is set) there is a 30 s wait until a
new attempt is started.
The respective errors must alway have a
shorter interval than 5 minutes (started
after restart). The modulation is switched
off immediately after every detection.
Check load of the device.
Reset by enable or line voltage ON/OFF.
