12
de-energized, 13 -
14 interrupted
Line voltage too low
Line voltage below a fixed 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 fixed limit for at least
2 s.
Check line voltage.
13
de-energized, 13 -
14 interrupted
Line voltage too high
Line voltage above fixed 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 volt-
age drops below the fixed limit for at
least 2 s.
Check line voltage.

Error peak current / overload
If the output current increases above the
specified limit (even in a short time-
frame) the device will switch-off.
After a switch off the controller waits for
5 s (cooling phase) then the controller
attempt a start.
If a further 250 deactivations occur as a
result, a fi nal switch-off will occur accom-
panied by a fault message.
Should no further switch off be exceeded
in 120 sec. the counter will be reset.

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

de-energized, 13 -
14 interrupted
Temperature err.
Excess of the max. permissible compo-
nent temperature.
Controller switches off motor. Automatic
restarting after cooling down.
Check cooling of the controller

14 interrupted
System / internal error
Motorcontrol error group: "System"
Possible causes: Current sensor adjust-
ment defective (hardware error), motor
parameters missing
Controller performs automatic reset.
