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 device with pilot
pressure, then switch on the medium.
If the position of the pilot air ports for installation of the hoses
is unfavorable, these can be aligned steplessly by rotating
the actuator through 360°.
