Insulation faults
A
If an insulation fault occurs during operation, and the indicator lamp displays an insu-
lation fault, the operator may proceed as follows:
- Switch the switches of all external equipment and the heating system to OFF and
press the reset button for at least 3 seconds to delete the fault.
- If the indicator lamp does not go out, the fault lies in the generator.
f
No further work may be carried out.
- If the indicator lamp goes out, the switches of the heating system and external
equipment can be switched back to ON one after another until a message again
appears and the system is shut-down.
- The equipment found to be faulty must be removed or must not be engaged, and
the reset button must be pressed for at least 3 seconds to delete the fault.
A
Operation may now be continued - without the faulty equipment, of course.
A
The generator or electrical consumer found to be faulty must be
checked or repaired by a specialist electrician. Only then may
work again be carried out with the screed and equipment.
