3 BASIC SAFETY INSTRUCTIONS

These safety instructions do not make allowance for any contin-

gencies and events which may arise during installation, operation

and maintenance.

The operator is responsible for observing the location-specic safety

regulations, also with reference to personnel.

Risk of injury due to high pressure in the system or device.

▶Before working on the system or device, switch o the pressure

and ventilate and empty the lines.

Risk of injury due to electric shock.

▶Before working on the device or system, switch o the power

supply and secure to prevent reactivation.

▶Observe the applicable accident prevention regulations and

safety regulations for electrical devices.

Risk of burns or re from hot device surfaces due to prolonged

operation.

▶Keep the device away from highly ammable substances and

media and do not touch with bare hands.

Risk of injury due to malfunctioning valves that operate with

alternating current (AC).

A seized core causes the solenoid to overheat, which leads to

functional failure.

▶Monitor the working process for proper function.

General hazardous situations.

Ensure the following the prevent injuries:

▶the device only when it is in perfect condition and in

accordance with the operating instructions.

▶Do not make any internal or external changes to the device and

do not subject it to mechanical stress.

▶Secure device or system to prevent unintentional activation.

▶Make sure only trained technicians carry out installation and

maintenance work.

▶Install the valves according to the regulations applicable in the

respective country.

▶After an interruption in the power supply, ensure that the process

is restarted in a controlled manner.

▶Observe the general rules of technology.

5 INSTALLATION

Danger

Risk of injury due to high pressure in the system or device.

▶Before working on the system or device, switch o the pressure

and ventilate and empty the lines.

Risk of injury due to electric shock.

▶Before working on the system or device, switch o the power

supply and secure to prevent reactivation.

▶Observe the applicable accident prevention regulations and

safety regulations for electrical devices.

▶Only connect protection classIII devices (without protective con-

ductor) to SELV or PELV power sources.

▶Only use cable plug for matching solenoid variant. Cable plugB

must not be used for a protection classIII device.

English

Warning

Risk of injury due to improper installation.

▶Installation may only be performed with trained technical personnel

with suitable tools.

▶Secure the system against unintentional activation.

▶Following installation, ensure a controlled restart.

5.1 Fluidic installation

Installation position: any, preferably solenoid facing upward.

→Check pipelines for soiling and clean if required.

→Install a dirt trap to protect against disruptions (mesh width:

0.2–0.4mm).

Note ow direction. Letters on the housing indicate the ow

direction: from 1(P) →2(A).

5.1.1 Devices with threaded connection

note

Caution: risk of breakage.

▶Do not use the solenoid as a lever arm.

→Seal the thread with PTFE tape.

→Hold the device on the housing using an open-end wrench and

screw into the pipeline.

5.1.2 Devices with ange connection

→Remove protective cover.

→Loosen nut and remove solenoid.

Warning

Risk of injury due to medium leak.

▶Ensure that the seals provided t the valve properly.

▶Ensure that the manifold is level.

▶Ensure sucient surface quality of the manifold.

→Insert the seal into the housing.

→Screw the housing onto the manifold, observing the maximum

tightening torque of 1Nm.

English

5.3 Rotating the solenoid

Warning

Risk of injury due to electric shock.

If there is no protective conductor function between the solenoid

and housing, there is a risk of electric shock.

▶Check the protective conductor function after installing the

solenoid.

Risk of injury due to overheating or re hazard.

Connecting the solenoid without rst installing the armature will

lead to overheating and will destroy the solenoid.

▶Only connect the solenoid after the armature has been installed.

The solenoid can be rotated by 4x90°. 2x180° in case of a block

installation.

→Loosen the nut.

→Rotate the solenoid.

→Screw in the nut with an open-end wrench, observing the
