Hazardous voltages inside
the measuring amplifier with 230 V supply
voltage (type 46.31.2x).
Touching live parts can result in death, serious injury or considerable
property damage.
•
Only qualified skilled persons are permitted to adjust the measuring
amplifier.
The measuring amplifier will only show its nominal characteristics
after a warm-up time of approximately 15 minutes.

5.3.1 Adjustment for symmetric displacement sensors
With symmetric displacement sensors, the electrical zero is at the center of the
nominal stroke. Typically, the voltage output of the measuring amplifier provides
a symmetric output signal (-10 V...0 V...+10 V) for a symmetric displacement
sensor. The current output provides a current of 12 mA (output ranges
4 mA...12 mA...20 mA) at the zero position.
