PNEUMATIC INSTALLATION

DANGER!
Risk of injury from high pressure in the equipment/device.
▶ Before working on equipment or device, switch off the pressure
and deaerate/drain lines.

Procedure:
→
Connect the control medium to the pilot air port (1)
(3 – 7 bar; instrument air, free of oil, water and dust).
→
Attach the exhaust air line or a silencer to the exhaust air port (3)
and, if available to the exhaust air port (3.1) (see "Fig. 10").
Keep the adjacent supply pressure always at least 0.5 – 1
bar above the pressure which is required to move the actuator
to its end position. This ensures that the control behavior is
not extremely negatively affected in the upper stroke range on
account of too little pressure difference.

During operation keep the fluctuations of the pressure supply
as low as possible (max. ±10 %). If fluctuations are greater,
the control parameters measured with the X.TUNE function
are not optimum.
