(NO)

→ Type 0344: Connect vacuum pump to connection R.

english

Type 0340, 0343, 0344

Operating principle 3/2-way valve Type 0343:

Standard Version

(NC)

Continuity A → R normally open, connect vacuum generator to R, external air to P, auxiliary control air to Z

(NO)

Continuity P → B normally open, connect vacuum generator to R, external air to P, auxiliary control air to Z

The externally controlled valve, Type 0343, requires auxiliary control air which is at least 2 bar above operating pressure

Protection class: IP65 in accordance with DIN EN 60529 /

IEC 60529 with cable plug, e. g. Bürkert Type 2508

4.2 Application conditions

Ambient temperature: 0 °C ... +55 °C Medium temperature: 0 °C ... +90 °C Viscosity (Type 0340): 21 mm

Media Type 0340: neutral media, compressed air, water,

hydraulic oil Type 0343 / 0344: neutral gas, compressed air, vacuum Operating duration: Unless otherwise indicated on the type label,

the solenoid system is suitable for continuous

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

4.3 Conformity

5.1 Safety instructions

Danger!

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.

english

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.

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.

Type 0340, 0343, 0344

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.

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.

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.

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 galvanically 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.

position.

If malfunctions occur, check:

→ the device has been installed according to the instructions, → the electrical and fluid connections are correct, → the device is not damaged and all screws have been tightened, → the voltage and pressure have been switched on, → the pipelines are clean, → corresponding orifice is used in vacuum mode of the pump

capacity (Type 0343 / 0344).

→ Type 0343: operating and control pressure (control pressure must

be at least 2 bar above operating pressure).

Valve does not switch

Possible cause:

• Short-circuit or coil interrupted.

• Medium pressure outside the permitted pressure range.

• Manual emergency actuation locked.

Valve does not close

Possible cause:

• Internal space of the valve is dirty.

• Manual emergency actuation locked.
