4.3 Isolation monitor
The function of the protective insulation
monitoring measure must be checked
every day before starting work.
A
This check only checks the function of
the insulation monitor, not whether an in-
sulation fault has occurred on the heat-
ing sections or consumers.
- Start the paver's 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.
f
The screed and equipment must be checked or repaired by a specialist electri-
cian. Only then may work again be undertaken with the screed and equipment.
f
Danger due to electrical voltage
f
Non-adherence to the safety precautions and safety regulations
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.
