Electrical system insulation monitoring
The function of the protective insulation
monitoring measure must be checked
every day before starting work.
This check only checks the function of
A
the insulation monitor, not whether an in-
sulation error has occurred on the heat-
ing sections or consumers.
- Start the paver finisher's drive engine.
- Switch heating system switch (1)
to ON.
- Press test button (2).
- The indicator lamp integrated into the
test button signals "insulation fault".
- Press reset button (3) for at least
3 sec. to delete the simulated fault.
- The indicator lamp goes out.
f If the test is conducted successfully,
work may be undertaken with the screed
and external consumers may be used.
If the "insulation fault" indicator lamp displays a fault even before the test button is
pressed or if no fault is displayed during the simulation, work must not be undertaken
with the screed or with connected, external equipment.
The screed and equipment must be checked or repaired by a specialist electri-
f
cian. Only then may work again be undertaken with the screed and equipment.
Danger due to electrical voltage
f
Non-adherence to the safety precautions and safety regulations
f
when operating the electric screed heating system leads to a
risk of electric shock.
Danger to life.
All maintenance and repair work on the screed's electrical system may be car-
ried out by a specialist electrician only.
