6.3 General information on the heating system
The electric heating system is supplied
with power by a generator on board the
paver finisher which is controlled fully-
automatically in accordance with re-
quirements.
Heating resistors in the form of heating
strips ensure direct temperature transi-
tion and even distribution of heat.
Each screed section is heated by three
heating strips. Two can be found on the
bottom plate and one on the tamper
knife.
The temperature display can be called
up for the individual screed sections or
as a mean value for all sections. Tem-
perature regulation is carried out for all
screed sections together.
The heater is connected to other fitted
screed components via simple plug con-
nections.
The heating system can be operated in
an energy saving mode in which not all
heating sections are active at the same
time.
In the event of sensor failure, the heater
can continue to be operated via an
emergency programme.
The switch cabinet is equipped with an
additional 230 V socket for external con-
sumers (e.g. additional lighting).
Since fuels (gas, diesel) are not handled and insulation monitoring takes place, max-
imum possible protection of personnel is offered.
f Beware of hot surfaces! Danger of burning!
f Maintenance and repair work on electrical systems with medium voltage levels, e.g.
the screed heater, may only be carried out by specialist electricians or persons in-
structed in electrical engineering work if the appropriate test devices are used.
Always comply with relevant technical electrical protection precautions. Danger to life
as a result of accidents involving medium voltage levels.
