1. Introduction

The analog -digital-converterAWA/2X12Bisused asan input moduleforthe electriccamswitchesof

the CamCon series.The converterhastwoindependent voltage -(-10V-+10Vrespective0-+10V)or

powerinputs(0-20mA)with aresolution of12Bit, that can be connected viaa6poledatacableto the

externalinterfaceofthe CamCon devicesDC50/561, 90 and 115. Byswitching severaldevicesin

seriesconnection it ispossible to connect up to 5 AWA/2X12Banalog digitalconverters.

2. Assembly

The deviceisclip-locked onto an "ENcarrierrail" inthe switchboard(see alsochapter

"6.3. Calibration"on page 8).The grounding pinsand cablemantlingsareto be put on the

shortestwaypossibleonto serialgrounding clipnextto the device. The grounded

assemblyplate and itselectricalconnection to the "ENcarrierrail" allowan excelent

grounding ofthe disturbancesonto the covering. All cableconnectionsareto be switched

inacoldstate !The externalinterfaceofthe CamCon (e.g. DC16/50/90 orDC115)is

connected with acableofthe type: KKyy/IO-XX (yy =CamCon Type /XX =length in

meters) to the plug "external interface IN" or "ext.Int.IN" on the module. Everyother

deviceisconnected to the plug "external interface OUT" or "ext.Int.OUT" with acable

ofthe sametype. The data linesofthe externalinterfacehaveto be galvanically

separated with an opticalcoupler,theyhaveto be placed and covered separatelyand the

coverhasto be grounded on both ends.Analog signalshaveto be placed and covered

separatelyand the coverhasto be grounded on one end. The supplyvoltage hasto be

example

connected separatlyforeverymodule and measures24VDC +/-20%.

Note: The analog -digital-converterhasto be switched to the end ofthe interface row.

3. StatusLED

The analog -digital-converterhas2 statusLEDs(see also chapter6.3. Calibration).

LED 1 indicatesthe presence ofsupply-power.

LED 2 indicatesthat no data exchange viaaCamCon DC50, 90 orDC115CamCon isdone.

Possiblecausesare: The cablelength adjusted at the CamCon outrunsthe maximumlength

of300 meters,the CamCon DC50, 90 orDC115 isswitched off,i.e. the data exchange is

interrupted (broken wire).

6. Configuration

6.1. Changetheinput - signal level

The analog inputs'signallevelcan be changed bysolding bridgeson the solderside ofthe

AWA/2X12B'sprinted circuit board.

The following input signalscan be set: "0-20mA", "-10V-+10V" or"0 -+10V".

The adjusted signallevelismarked foreveryinput bywith a cross on the metalcap.

Tochange the input level,detachall cableconnectionsfromthe device.,

remove the device fromthe switchchest, open the floorpartat the devices

side using ascrewdriverand pull the printed circuitboardout ofthe floor

part. Onthe solding side ofthe printed circuitboardareto solding bridges

forsignalinput 1 and 2 which are called SJ1 to SJ4 in the drawing. Via SJ1

and SJ"the signallevelforinput 1and viaSJ3to SJ4forinput 2areset.

Having adjusted the desired signallevel,the input switching hasto be

equalized anew. See also chapter"6.3. Calibration"on page 8.

6.1.1. Solding bridgeSJ1

To switchthe 1stanalog input fromunipolar(0V-10V)to the bipolar(-10V

-+10V)voltage measuring the solding bridge SJ1hasto be closed. Thissolding bridge mayonlybe

closed, ifthe solding bridge SJ2 isopen.

6.1.2. Solding bridgeSJ2

To switch the 1st analog input fromvoltage -to currencyinput, the solding bridge SJ2 hasto be closed.

6.1.3. Solding bridgeSJ3

Toswitchthe 2nd analog input fromvoltage -to currencyinput, the solding bridge SJ3hasto be

closed.

6.1.4. Solding bridgeSJ4

Toswitchthe 2nd analog input fromunipolar(0V-10V)to the bipolar(-10V-+10V)voltage measuring

the solding bridge SJ4hasto be closed. Thissolding bridge mayonlybe closed, ifthe solding bridge

SJ3 isopen.

6.2. Reference voltagesupply

Twointernvoltages(+4.096 and +5V)areavaible, an externalvoltage sourcemaybe

enabled byswitching themboth of.The choiceismade viaajumperledge on the

component side ofthe printed circuitboard. Tochange the referencevoltage, remove

the cap byunscrewing the fourcap nutsand chooseyourvoltage sourceat jumper

JP1.

Bridge at 1+2 = +5V Ref. voltage fromthe operating voltage.

Bridge at 2+3 = +4.096V Ref. voltage byprecission voltage controller

(default).

Bridge open =external Ref. voltage externalbyat least +1Vto a maximumof+5V.

Note: Ifthe sourceofreferencevoltage ischanged, the input switching hasto be equilibrated

anew. (see also chapter"6.3. Calibration").

6.3. Calibration

Ifthe AWA/2X12Bmodulehasto be eliquibrated anew,

removethe case'stop byunscrewing the fourcap nuts,

to get to the pontentiometer.Fourmulti-geartrimmerare

provided forthispurpose. These are:

R36 =Amplification input 1

R37 =Offset input 1 at ±10Vinput.

R39 =Amplification input 2

R40 =Offset input 2 at ±10Vinput.

6.3.1. Calibration during powerinput

Set aconstant powersourceat clamps5and 6forinput

1orat clamps8and 9forinput 2. The value ofcurrency

hasto be knownwith great accuracy.It shouldbe inthe range of15 to 20 mA.Nowchoosethe menu

inwhichthisvalue isdisplayed inthe device(CamCon).You areableto increasethisdisplayed value

byturning to the leftat the R36 (input 1)orR39 (input 2)orde-creaseitbyturning to the right. Set the

nowpresent current orit'scorresponding value and sealthe potentiometerwith sealing wax.Atthe

potentiometers atR37 and R40 no configuration can be done while being undercurrent.

6.3.2. Calibration during voltage-input 0- +10V

Set a voltage source to the terminals5 and 6 forinput 1 or8 and 9 forinput 2. The value of voltage has

to be knownwith great accuracy.It shouldbe inthe range o+5to +10 Volt. Nowchoosethe menu in

whichthisvalue isdisplayed inthe device(CamCon).You areableto increasethisdisplayed value by

turning to the leftat the R36 (input 1)orR39 (input 2)orde-creaseitbyturning to the right. Set the

nowpresent voltage orit'scorresponding value and sealthe potentiometerwith sealing waxorTip-EX.

Atthe potentiometers atR37 and R40 no configuration can be done whilebeing underavoltage about

0 to +10 Volt.

6.3.3. Calibration during voltage-input -10V- +10V

Bypass the terminals5and 6forinput 1or8and 9forinput 2using awirewith alength of5cmand

choose the menu in which thisvalue isdisplayed in the device (CamCon). Nowset the dislay-value to0

byturning to the leftorright at R37 (input 1)orR40 (input2).Then sealthe potentiometerwith sealing

waxorTip-EX.

Nowset avoltage sourceto the terminals5and 6forinput 1or8and 9forinput 2. The value of

voltage hasto be knownwith great accuracy.It shouldbe inthe range o+5to +10 Volt. Nowchoose

the menu inwhichthisvalue isdisplayed inthe device(CamCon).It shouldbe inthe range o+5to +10

Volt. Nowchoosethe menu inwhichthisvalue isdisplayed inthe device(CamCon).You areableto

increasethisdisplayed value byturning to the leftat the R36 (input 1)orR39 (input 2)orde-creaseit

byturning to the right. Set the nowpresent voltage orit'scorresponding value and sealthe

potentiometerwith sealing wax.Ifthe voltage sourceispotentiallyfree towardsthe AWA/2X12B,you

areableto reservethe polarityofthe voltage at the terminals5+6or8+9. The displaynowshould

showthe negative value ofthe same size asit wasthe positive before.
