1. Introduction
The analog - digital - converter AWA/SSI/12 of the next generation offers the possibilty to meassure
voltages from 0 to +10 Volt or from 0 to 20mA with a resolution of 12 Bit. The enclosed pre-resistor
enables adjusting and configuring the measuring range. The measured value is read out via the serial
synchronous interface.

with 4096 steps.
2. Assembly
The device is clip-locked onto an "EN carrier rail" in the switchboard (see also chapter "5.
Dimensions" on page 6). 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 SSI data lines of the external interface
are galvanically separated with an optical couplerthey have to be shielded, wired as pairs and the
shield has to be laid on ground with both cable ends. Analog signals have to be placed and covered
separately and the cover has to be grounded on one end. The supply voltage measures 24V DC +/20%.

4. Configuration
.
4.1. Change the input - signal level
The analog inputs' signal level can be changed by solding bridges on the solder side of the
AWA/2X12B's printed circuit board.
The following input signals can be set: "0-20mA" or "0 - +10V".".
The adjusted signal level is marked for every input by with a cross on the metal cap.
To change the input level, detach all cable connections from the device.,
remove the device from the switch chest, open the floor part at
the devices side using a screwdriver and pull the printed circuit
board out of the floor part. On the solding side of the printed
circuit board are to solding bridges for signal input 1 and 2 which
are called SJ1 to SJ4. For the measuring of a currency signal
the soldingbridge SJ" has to be closed. To measure a voltage
signal, it has to be openened.
Note:
Having adjusted the desired signal level, the input switching has
to be equalized anew. See also chapter "4.3. Calibration".

4.2. Reference voltage supply
Two intern voltages (+4.096 and +5V) are avaible, an external voltage source may
be enabled by switching them both of. The choice is made via a jumper ledge on the
component side of the printed circuit board. To change the reference voltage,
remove the cap by unscrewing the four cap nuts and choose your voltage source at
jumper JP1.
Bridge at 1+2
Bridge at 2+3
= +5V
= +4.096V

= external
Note:
Ref. voltage from the operating voltage.
Ref. voltage by precission voltage controller
(default).
Ref. voltage external by at least +1V to a maximum of +5V.
If the source of reference voltage is changed, the input switching has to be equilibrated
anew. (see also chapter "4.3. Calibration").
4.3. Calibration
If the AWA/2X12B module has to be eliquibrated anew,
remove the case's top by unscrewing the four cap nuts,
to get to the pontentiometer. Four multi-gear trimmer
called R36 is provided for this purpose.
4.3.1. Calibration during power input
Set a constant power source to the terminals 5 and 6.
The value of currency has to be known with great
accuracy. It should be in the range of 15 to 20 mA. Now
choose the menu in which this value is displayed in the
device (CamCon). You are able to increase this
displayed value by turning to the left at the R36 (input 1)
or R39 (input 2) or de-crease it by turning to the right.
Set the now present current or it's corresponding value
and seal the potentiometer with sealing wax.
4.3.2. Calibration during voltage-input 0 - +10V
Set a voltage source to the terminals 5 and 6. The value of voltage has to be known with great
accuracy. It should be in the range o+5 to +10 Volt. Now choose the menu in which this value is
displayed in the device (CamCon).You are able to increase this displayed value by turning to the left
at the R36 (input 1) or R39 (input 2) or de-crease it by turning to the right. Set the now present
voltage or it's corresponding value and seal the potentiometer with sealing wax.
