8.8 Pneumatic connection
DANGER!
Danger – high pressure in the equipment!
▶ Before loosening the lines and 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 authorised for the indicated pressure
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 product with
pilot pressure, then switch on the medium.
8.8.1 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. 39: Pneumatic connection")
Silencer
For the versions with a plug-in connection the silencer for reducing
Installation
the exhaust air noise is supplied loose.
→
Plug the silencer into the free air discharge connection 2
(see "Fig. 39: Pneumatic connection")
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 function I:
→
Connect the control medium to the pilot air port 1 and 2 of the
actuator (see "Fig. 39: Pneumatic connection")
Pressure on connection 1 opens the valve.
Pressure on connection 2 closes the valve.
