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.
