operation

Important information for functional reliability during continuous

operation! If standstill for a long period at least 1-2 operation

per day are recommended.

Service life: High switching frequency and high pressures

reduce the service life

Risk of injury from high pressure in the equipment!

▶Before loosening the lines and valves, turn off the pressure and

vent the lines.

Risk of injury due to electrical shock!

▶Before reaching into the system, switch off the power supply and

secure to prevent reactivation!

▶Observe applicable accident prevention and safety regulations for

electrical equipment!

WARNING!

Risk of injury from improper installation!

▶Installation may be carried out by authorized technicians only and

with the appropriate tools!

Risk of injury from unintentional activation of the system and an

uncontrolled restart!

▶Secure system from unintentional activation.

▶Following installation, ensure a controlled restart.

5.2 Before installation

Installation position: any, actuator preferably upwards.

Procedure:

→Check pipelines for dirt and clean.

→Install a dirt filter before the valve inlet (≤ 500 µm).

5.3 Installation

NOTE!

Caution risk of breakage!

• Do not use the coil as a lifting arm.

→Hold the device with a open-end wrench on the body and screw

into the pipeline.

Valve body must not be installed under tension.

→Observe pin assignment according to switching function and

identification.

english

5.4 Manual emergency actuation

CAUTION!

Discharge of medium due to loss of the O-rings!

▶If the O-rings are lost, the valve will leak. Medium may be discharged.

NOTE!

Caution!

• When the manual emergency actuation is locked, the valve can no

longer be actuated electrically.

Turn

DANGER!

Discharge of medium due to leaking device!

If the O-rings are forgotten or incorrectly inserted during installation

of the pilot valve, the device will be damaged and medium will be

discharged.

▶Before screwing in the pilot valve, correctly insert O-rings into the

depressions.

5.5 Electrical connection of the cable plug

WARNING!

Risk of injury due to electrical shock!

▶Before reaching into the system, switch off the power supply and

secure to prevent reactivation!

▶Observe applicable accident prevention and safety regulations for

electrical equipment!

If the protective conductor contact between the coil and body is

missing, there is danger of electrical shock!

▶Always connect protective conductor.

▶Check electrical continuity between coil and body.

english

Procedure:

→Tighten cable plug (for permitted types see data sheet), observing

max. torque 1 Nm.

→Check that seal is fitted correctly.

→Connect protective conductor and check electrical continuity between

coil and body.

Authorized cable plug e.g.

Type 2508 or other suitable

cable plug in accordance with

DIN EN 175301-803 Form A

Seal

max. 1 Nm

5.5.1 Electrical connection - Pulse

DC connections:

Terminal 1 = closed +

Terminal 2 = open +

Terminal 3 = GND -

Terminal 4 = Protective conductor

Protective conductor

connection

24 3

The connection terminals in the cable plug are identified with

the numbers 1 to 3 according to the terminals on the valve.

Procedure:

→Connect the pulse valves (variable code CF 02).

→For direct current versions connect negative terminal to terminal 3.

english

NOTE!

Important information:

• Avoid emitting pulses simultaneously to both coil windings.

• Do not switch any other consumers (relays, etc.) at the same time

as the terminals.

• The coil connection, to which voltage is not applied, must be galvani-

cally isolated (open).

• If two or more valves are switched in parallel, ensure that this

requirement is met by using 2-pole or multi-pole switches.

6 MAINTENANCE, TROUBLESHOOTING

6.1 Safety instructions
