Safety precautions
The machine is fitted as standard with the following
safety precautions:
•
•
•
•
Main switch
Cover switch
Short circuit and overload safety
Pump fan guards
Main switch
With the main switch (Fig. 2-1) the machine can be
made voltage free. The main switch can also be used as
an emergency stop.
Fig. 2-1: Main switch
Cover switch
The Cover switch prevents the seal beam(s) getting hot as a result of a malfunction or defect when the
Cover is open.
WARNING
THE SAFETY WORKS CORRECTLY WHEN THE MACHINE APPLIES A VACUUM, WHEN THE
COVER IS ALMOST CLOSED. THIS SAFETY MUST BE CHECKED FOR CORRECT OPERATION
REGULARLY AND, WHEN NECESSARY, IT MUST BE REPAIRED IMMEDIATELY.
Short circuit and overload safety
The machine is equipped with safety measures that prevent components becoming overheated by
overloading or short-circuiting.
Notes!

•
The overload safety circuits on the seal transformers are self-resetting, which means that the
safety resets itself when the transformer has cooled down sufficiently. Operate the machine at a
slower speed or decrease the sealing time if the overload safety is trips regularly. Obviously,
tripping the overload safety shortens the lifetime of the transformer.
On some machines extra sealing power (see chapter 1) can be installed. Consult your dealer.
The short-circuit safety on the seal transformer is not self-resetting, which means that the
transformer must be replaced when this safety is tripped. Consult your dealer for this.
Pump fan guards
The vacuum pump is fitted with guards that prevent you touching the fan while it is running.

All safety measures must be mounted correctly and may only be removed for maintenance and
repair work by suitably trained and authorised service technicians.
The machine may never be used if the safety measures are not complete or not present, or
when they are or have been disabled.
Safety measures may never be bridged.
