Installation
WARNING!
Risk of injury from unsuitable connection hoses.
▶ Use only hoses which are authorised for the indicated pres-
sure and temperature range.
▶ Observe the data sheet specifications from the hose
manufacturers.
For control function I: Danger if pilot pressure fails.
For control function I control and resetting occur pneumatically.
If the pressure fails, no defined position is reached.
▶ To ensure a controlled restart, first pressurize the device with
pilot pressure, then switch on the medium.
7.8.1 Connection of the control medium
Control functions A and B
→ Connect the control medium to the pilot air port 1 of the actuator
(see "Fig. 13: Align actuator").
Control function A, 3-position actuator
→ Connect the control medium to the pilot air port 1 and 2 of
the actuator (see "Fig. 2" in chapter 5)
Pressure on connection 1 opens the valve,
Pressure on both connections sets the mid- position.
Control function I
→ Connect the control medium to the pilot air port 1 and 2 of
the actuator (see "Fig. 14: Pneumatic connection")
Pressure on connection 1 opens the valve.
Pressure on connection 2 closes the valve.
