6.3. 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 are

provided for this purpose. These are:

R36

= Amplification input 1

= Offset input 1 at ± 10V input.

R37

R39

= Amplification input 2

= Offset input 2 at ± 10V input.

R40

6.3.1. Calibration during power input

Set a constant power source at clamps 5 and 6 for input

1 or at clamps 8 and 9 for input 2. 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. At the

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

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

Set a voltage source to the terminals 5 and 6 for input 1 or 8 and 9 for input 2. 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 or Tip-EX.

At the potentiometers atR37 and R40 no configuration can be done while being under a voltage about

0 to +10 Volt.

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

Bypass the terminals 5 and 6 for input 1 or 8 and 9 for input 2 using a wire with a length of 5cm and

choose the menu in which this value is displayed in the device (CamCon). Now set the dislay-value to 0

by turning to the left or right at R37 (input 1) or R40 (input2). Then seal the potentiometer with sealing

wax or Tip-EX.

Now set a voltage source to the terminals 5 and 6 for input 1 or 8 and 9 for input 2. 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). 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. If the voltage source is potentially free towards the AWA/2X12B, you

are able to reserve the polarity of the voltage at the terminals 5 + 6 or 8 + 9. The display now should

show the negative value of the same size as it was the positive before.
