of the power

low voltages, the
operation of the system
is stopped. If the
appropriate voltage
value is restored,
then the operation
will automatically be
restarted. • The power grid has to be
checked.

Replace the cable with one
with a suitable cross-section.
While doing so, take into
consideration the voltage
drop on the controller’s
supply point.
