Connection of the control medium
DANGER
Risk of injury from high pressure in the equipment.
▶ Before dismounting pneumatic lines or valves, turn off the
pressure and vent the lines.
WARNING
Risk of injury from unsuitable connection hoses.
Hoses which cannot withstand the pressure and temperature
range may result in hazardous situations.
▶ Use only hoses which are authorized for the indicated pres-
sure and temperature range.
▶ Observe the data sheet specifications from the hose
manufacturers.
For control function I: Danger if control pressure fails.
For control function I control and resetting occur pneumati-
cally. If the pressure fails, no defined position is reached.
▶ To ensure a controlled restart, first pressurize the device with
control pressure, then switch on the medium.
If the position of the control air connections is unfa-
vorable for installation of the hoses, these can be step-
lessly aligned by turning the actuator through 360°.
The procedure is described in chapter "6.3 Rotating the drive".

Assembly
Control function A:
On the lower connection of the actuator.
Control function B:
On the upper connection of the actuator.
Control function I:

If used in an aggressive environment, we recommend
conveying all free pneumatic connections into a neutral
atmosphere with the aid of a pneumatic hose.
Control air hose: Control air hoses of size 1/4" can be used.
