1. Introduction

The analog - digital - converter AWA/2X12B is used as an input module for the electric camswitches of

the CamCon series. The converter has two independent voltage - (-10V - +10V respective 0 - +10V) or

power inputs (0 - 20mA) with a resolution of 12Bit, that can be connected via a 6 pole datacable to the

external interface of the CamCon devices DC50/561, 90 and 115. By switching several devices in

series connection it is possible to connect up to 5 AWA/2X12B analog digital converters.

2. Assembly

The device is clip-locked onto an "EN carrier rail" in the switchboard (see also chapter

"6.3. Calibration" on page 8). The grounding pins and cable mantlings are to be put on the

shortest way possible onto serial grounding clip next to the device. The grounded

assembly plate and its electrical connection to the "EN carrier rail" allow an excelent

grounding of the disturbances onto the covering. All cable connections are to be switched

in a cold state ! The external interface of the CamCon (e.g. DC16/50/90 or DC115) is

connected with a cable of the type: KKyy/IO-XX (yy = CamCon Type / XX = length in

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

device is connected to the plug "external interface OUT" or "ext.Int. OUT" with a cable

of the same type. The data lines of the external interface have to be galvanically

separated with an optical coupler, they have to be placed and covered separately and the

cover has to be grounded on both ends. Analog signals have to be placed and covered

separately and the cover has to be grounded on one end. The supply voltage has to be

connected separatly for every module and measures 24V DC +/-20%.

Note:

The analog - digital - converter has to be switched to the end of the interface row.

3. Status LED

The analog - digital - converter has 2 status LEDs (see also chapter 6.3. Calibration).

LED 1

indicates the presence of supply-power.

LED 2

indicates that no data exchange via a CamCon DC50, 90 or DC115CamCon is done.

Possible causes are: The cable length adjusted at the CamCon outruns the maximum length

of 300 meters, the CamCon DC50, 90 or DC115 is switched off, i.e. the data exchange is

interrupted (broken wire).
