Electrical connection

For electrical installation, observe the relevantelectrotechnical regulations and the accidentprevention regulations that apply in the countryof use. In Germany, these are the VDE regula-tions and the accident prevention regulationsof the employers’ liability insurance.The following regulations apply to installationin hazardous areas: EN 60079-14:2008Explosive atmospheres – Part 14: ElectricalInstallations, design, selection and erection (orVDE 0165 Part 1) and EN 61241-14:2004Electrical Apparatus for Use in the Presence ofCombustible Dust (or VDE 0165 Part 1).

Electrical connections in compliance withtype of protection “d“

Connect the devices using suitable cable entriesor conduit systems that comply with EN 60079-1:2007 Explosive Atmospheres –Part 1: Equipment Protection by FlameproofEnclosures “d“, Clauses 13.1 and 13.2, andfor which a seperate test certificate is available.Do not use cable entries and blanking plugs ofsimple construction.Install the connecting cable properly so that itis protected against mechanical damage.If the temperature at the inlet parts exceeds70 °C, use a temperature-resistant connectingcable.Include the devices in the on-site equipotentialbonding system.

Connecting cable

The power supply cable is connected through acable entry � to screw terminals � and � un-derneath the enclosure cover (Fig. 2 and 3).For electrical installation, the electric connect-ing data (see “Technical Data“, page 5) mustbe observed.The device must be mounted so that the cableentry � preferably faces down, or if this is notpossible, aligned in the horizontal positionIt is recommended to use connecting cables witha conductor cross-section of 0.2 to 2.5 mm2

and an external diameter of 5 to 8 mm areused.Protect the conductor ends against splicing,e. g. by using wire-end ferrules.

Do not loosen enameled screws onthe enclosure.

To prevent ignition of hazardous at-mospheres, open circuits before re-moving cover. Keep cover tightly

closed when in operation.

Degree of protection

The devices are protected against water anddust with an O-ring at the enclosure cover (seeFig. 19).Before mounting the enclosure cover � the O-ring � must be checked for damage and, ifnecessary, changed (see also “Servicing of ex-plosion-protected devices“, page 31).The attached enclosure cover � must be lockedby unscrewing a hexagon socket head screw �.

The required degree of protection IP 66 according to IEC 60529:1989can be only guaranteed with instal-

led enclosure cover, closed cable entry andproper installation of the connections.

When connecting to conduit systems use suit-able conduit entry sealant to maintain theingress protection.

Contacts

The devices are equipped either with one ortwo inductive proximity switches or two electricmicroswitches.For most applications, the contacts are adjustedto provide a signal when the actuator hasreached one of its end positions. The switchingpoint can also be adjusted to any position with-in the rotary range or travel range to signalizean intermediate position.

Switching point shift due to changes in temperature

The contacts and their actuating appliances aresensitive to changes in temperature.In order to ensure safe switching, the switchinghysteresis between the switching position of theactuator and the switching point of the contactmust be larger than the switching point shiftdue to changes in temperature.For this reason, when adjusting the contacts,the shift of the switching point must be com-pensated for with x turnings of the adjustmentscrew (see table “Adjustment data“).

Adjustment dataSwitching point shift �T = 50 K

Angle of rotation Travel� 2° � 0.8 mmTurning of the adjusting screwx = 1/16 x = 1/16

– 29 – EB 4747 EN

Inductive proximity switches

Principle of operationFor devices with inductive proximity switches,the shaft � has one or two adjustable metaltags � (see Fig. 20).When the metal tag � is within the magneticfield of the proximity switch, the proximityswitch is attenuated and the output has a highimpedance (switching function “Contact open“).When the metal tag � leaves the magneticfield, the proximity switch is unattenuated andthe output has low impedance (switching func-tion “Contact closed“).

Adjusting the switching pointsThe metal tags � of proximity switches thathave been mounted by the manufacturer areadjusted so that the proximity switches are un-attenuated in the switching positions of thecontrol valve (switching function “Contactclosed“).The metal tags � can be adjusted as follows toswitching points between 0° and 100° with ad-justing screws � using a screwdriver (blade4.5 mm):1 Unscrew enclosure cover � from the enclosure.2 Move control valve to the desired switching

position.3 Turn adjusting screw �, until the metal

tag � moves out of the magnetic field of theproximity switch and the output signalchanges.

4 To compensate for the switching point shiftdue to changes in temperature, turn adjust-ing screw � by x turnings (see table“Adjustment data“, page 28) in the oppositedirection.

5 Move control valve out of the switching po-sition and check whether the output signalchanges.

6 Move control valve to the switching positionagain and check the switching point.

7 Screw enclosure cover � onto the enclosure(see Fig. 21). Before mounting the enclosurecover � the O-ring � must be checked fordamage and, if necessary, changed.

Electric microswitches

Principle of operationFor devices with two electric microswitches, theshaft � has two adjustable cam disks � (seeFig. 22).Each cam disk � actuates an electric micro-switch by the roller on the switch lever.The electric microswitches have a double-throwcontact which can be used as make contact orbreak contact.

Adjusting the switching pointsThe cam disks � can be adjusted to switchingpoints between 0° and 100° with adjustingscrews � using a screwdriver (blade 4.5 mm)as follows:1 Unscrew enclosure � cover from the enclosure.2 Move control valve to the desired switching

position.3 Turn adjusting screw � until the cam

disk � actuates the electric microswitch andthe output signal changes.

Servicing explosion-protecteddevices

If a part of the device on which the explosionprotection is based needs to be serviced, thedevice must not be put back into operation untilan expert has inspected it according to explo-sion requirements, has issued an inspectioncertificate or given the device a mark of con-formity.Inspection by a qualified inspector is not re-quired if the manufacturer performs a routinetest on the device prior to putting it back intooperation. The passing of the routine test mustbe documented by attaching a mark of confor-mity to the device.Equipment used in explosive gas atmospheresin ambient temperature ranges correspondingto temperature class T4 or T5 may be used inexplosive dust atmospheres after servicing onlyif a new O-ring in the enclosure cover has beeninserted (see “Degree of protection“, page 27).
