3.1 General instructions for use of the instrument

Note:

Forsafetyreasons,theinstrumentmustonlybeoperatedwithinthe

permissibleprocessconditions.Youcannddetailedinformationon

the process conditions in chapter " Technical data" of the operating

instructions or on the type label.

Hencemakesurebeforemountingthatallpartsoftheinstrumentex-

posedtotheprocessaresuitablefortheexistingprocessconditions.

These are mainly:

• Active measuring component

• Processtting

• Process seal

Process conditions in particular are:

• Process pressure

• Process temperature

• Chemical properties of the medium

• Abrasionandmechanicalinuences

Protect your instrument against moisture ingress through the following

measures:

• Use a suitable connection cable (see chapter " Connecting to

power supply")

• Tighten the cable gland or plug connector

• Lead the connection cable downward in front of the cable entry or

plug connector

Thisappliesmainlytooutdoorinstallations,inareaswherehigh

humidityisexpected(e.g.throughcleaningprocesses)andoncooled

or heated vessels.

Note:

Make sure that during installation or maintenance no moisture or dirt

can get inside the instrument.

Tomaintainthehousingprotection,makesurethatthehousinglidis

closedduringoperationandlocked,ifnecessary.

Theventilationfortheelectronicshousingisrealisedviaalterele-

ment in the vicinity of the cable glands.

4 Connecting to power supply

4.1 Connecting

The voltage supply and signal output are connected via the spring-

loaded terminals in the housing.

Connection to the display and adjustment module or to the interface

adapter is carried out via contact pins in the housing.

Information:

The terminal block is pluggable and can be removed from the

electronics.Todothis,lifttheterminalblockwithasmallscrewdriver

andpullitout.Whenreinsertingtheterminalblock,youshouldhearit

snap in.

Proceed as follows:

1. Unscrew the housing lid

2. Ifadisplayandadjustmentmoduleisinstalled,removeitbyturn-

ing it slightly to the left

3. Loosen compression nut of the cable gland and remove blind

plug

4. Removeapprox.10cm(4in)ofthecablemantle,stripapprox.

1 cm (0.4 in) of insulation from the ends of the individual wires

5. Insert the cable into the sensor through the cable entry

Fig. 3: Connection steps 5 and 6 - Single chamber housing

6. Insert the wire ends into the terminals according to the wiring plan

Information:

Solidcoresaswellasexiblecoreswithwireendsleevesareinsert-

eddirectlyintotheterminalopenings.Incaseofexiblecoreswithout

endsleeves,presstheterminalfromabovewithasmallscrewdriver,

theterminalopeningisthenfree.Whenthescrewdriverisreleased,

the terminal closes again.

7. Check the hold of the wires in the terminals by lightly pulling on

them

8. Connecttheshieldingtotheinternalgroundterminal,connectthe

externalgroundterminaltopotentialequalisation

9. Tighten the compression nut of the cable entry gland. The seal

ring must completely encircle the cable

10. Reinsertthedisplayandadjustmentmodule,ifonewasinstalled

11. Screw the housing lid back on

5.1 Preparations

Make sure that the Bluetooth function of the display and adjustment

moduleisactivated.Forthis,theswitchonthebottomsidemustbe

set to " On".

O

Fig. 5: Activate Bluetooth

1 Switch

On = Bluetooth active

O = Bluetooth not active

The security concept of Bluetooth operation absolutely requires that

the default setting of the sensor PIN be changed.This prevents unau-

thorizedaccesstothesensor.

The default setting of the sensor PIN is " 0000". First of all you have

tochangethesensorPINintheadjustmentmenuofthesensor,e.g.

to " 1111":

1. Gotosetupviatheextendedoperation

2. Lock operation by changing sensor PIN

3. Enable operation again by entering the sensor PIN once more
