3.2.9.1
Fuses
The fuses protect the electrical components of the control circuit in the event
of faults.
3.2.9.2
Motor protection
The motor is protected against overloading by an overload release device. In the
event of overloading the release device switches off the motor and restarts it again
automatically after it has cooled down. If the motor is repeatedly switched off by
the release device, the cause of the fault is to be eliminated.
3.2.9.3
Automatic cutoff system
By closing the spray gun the machine is switched off by means of a pressure switch,
the time sequence of the automatic cutoff system starts. During the time sequence
the machine remains in operating condition. By opening the spray gun during the
time sequence the time gone is deleted, which means, when closing the spray gun
again, the time sequence starts from zero.
After the time to be set on a time relay has gone by, the operating condition is
deleted.
For restarting the machine, the start button on the control box at the washing site
must be switched on.
At works the time of the automatic cutoff device is set to approx. 5 minutes.
In case the time for the operating condition has to be changed, the setting has
to be carried out by an expert on the corresponding time relay in the main
switch cabinet.

Installation
4.1
Location
Frost protection
The machine, the long-distance pipings and the washing bays
have to be installed in such a manner to protect them from
frost.
The machine is designed for stationary installation on a
solid wall.
- 7 -
The machine must not be installed and operated
in fire and explosion hazard areas.
The satisfactory solidity of the wall
must be checked and approved by an expert
on site. If there is no sufficient solidity
of the wall for wall installation, the
machine is to be mounted on a scaffolding.
