CauTIon
risk of injury due to discharge of medium and
malfunctioning.
Medium may escape if the seals are not seated correctly. The
function of the device may be restricted by pressure losses.
▶ Ensure that all the seals are seated correctly.
risk of injury from damaged contacts.
Damaged contacts may result in a short circuit and
malfunctioning.
▶ Do not bend contacts.
▶ If contacts are damaged or bent, replace the affected
components.
▶ Do not switch on the device unless the components are in
perfect condition.

▶ Operate the device with direct current only!
▶ Prevent a pressure drop. Design the pressure supply with the
largest possible volume.

Danger
risk of injury from high pressure.
▶ Before loosening lines and valves, turn off the pressure and
vent the lines.
▶ Close the open connections not required with suitable plug
elements.
▶ Connections for the pilot control exhaust air (x) must not be
sealed.
▶ Check correct assignment of the connections 1 and 3 / 5.
They may by no means be interchanged.
CauTIon
uncontrolled reaction of the system due to back pressures.
Insufficient exhaust air ventilation can lead to unintended
switching of the valves due to back pressures.
▶ Ensure that exhaust air is vented properly (e.g. via a large
cable cross-section).
▶ Avoid pressure build-up in the exhaust air ducts. To do this,
use all exhaust air ports and pilot exhaust air ports of the
valve block and regularly check the exhaust air silencers and
replace them if required.
▶ Design the pressure supply with the largest possible volume
to prevent unwanted reaction of the system when switching
the valves.
