Note!
The end position cushioning on the cylinder is adjusted by factory at customer project values.
It's not necessary to change it if you don't change the configuration.

The end position cushioning of the main cylinder reduces
the impact energy when the applicator is operating at high
speeds and/or mass.
Adjust the end position cushioning so that the piston arrives
the end position definitively but does not strike it to hard.
A higher level of end position cushioning will reduce the lift
speed.
To increase the value of the end position cushioning turn
the setting screw (2) clockwise on cylinder (1).
To reduce the value of the end position cushioning turn
the setting screw (2) counterclockwise on cylinder (1).
The stopper with cushioning (guide rail) reduces the speed
of the cylinder Z shortly before impact when the applicator is
operated at higher cylinder speeds and with larger pads.
Adjustments like chapter „6.5 Adjustment of the Stopper
for Blow Mode"
Adjust the stopper with maximum compressed spring.
The stopper avoids the triggering of the labelling sensor by
the weight of the pad assembly at the inward motion in case
of an installation of 90° or 180°.
The adjustment must be done in the start position of the
applicator.
1. Loosen the counter nut of the stopper.
2. Turn the stopper until it easily touches the pad retainer.
Do not change the take over position of the pad by the
stopper.
3. Tighten the counter nut to fix the stopper.
The pressure reduction valve (2) can be used when labelling
pressure-sensitive products or considering general safety
aspects to reduce the pressure of the cylinder in Z-direction.
The standard value is 2.5 bar.
Connect the manometer between tube and exit (3) and
adjust the pressure to 2.5 bar with the knurled screw (1).
It is possible to order an upgraded set with a pressure
reduction valve.
Instructions are provided with the upgraded set.
