DANGER!
Risk of injury from high pressure in the system!
▶
Before loosening lines and valves, turn off the pressure and
vent the lines.
WARNING!
Risk of injury due to unsuitable connection hoses!
Hoses that cannot withstand the pressure and temperature
range can cause hazardous situations.
▶
Only use hoses that are permitted for the specified pressure
and temperature range.
▶
Note the data sheet information from the hose
manufacturers.
For control function I – risk of pilot pressure failure!
With control function I, the control unit and reset are pneumatic.
No defined position is reached during a pressure failure.
▶
To ensure a controlled restart of the device, first apply pilot
pressure and then activate the medium.
8.4.1
Connecting the control medium
If the position of the pilot air ports is unfavourable for
installing the hoses, these can be seamlessly aligned by
rotating the actuator by 360°.
The procedure is described in chapter
.

Control function A and B:
→
Connect control medium to pilot air port

of the actuator
(see „Image 18“).
Silencer
For devices with push-in connection, the silencer to reduce the
exhaust air volume is supplied unattached.
→
Connect the silencer to the free exhaust port

(see „Image 18“).
For usage in an aggressive environment, we
recommend using a pneumatic hose to drain all free
pneumatic ports in a neutral atmosphere.
