Setting the on-off valve
The on-off valve [33A] is a safety relevant part of the
applicator. It prevents an abrupt backward movement
of the applicator plate, when the compressed air is
switched on.
The on-off valve is factory-set. The setting is fixed with
locking varnish.
If the vacuum plate of the LA -TO moves back to the
home position very abruptly, as soon as the com-
pressed air is switched on, the on-off valve is not set
correctly or it is defective.
A
faulty setting
has to be corrected as described be-
low.
Exchange a
defective valve
. Set the new valve as
described below (not required, if the valve was ordered
at Avery Dennison).
Tools:
•
Screwdriver, small
•
Screw locking varnish
Setting:
1. Turn set screw [33B] up to the limit in direction
„slow“.
2. Plug in the supply air hose [33C]. Pull off the out-
hoses [33D].

3. Set the supply air pressure to 6 bar.
4. Slowly turn out the set screw, until the supply air
starts streaming through the valve.
5. Turn out set screw ½ turn further.
6. Switch off the supply air. Pull off the supply hose.
