Analog Interface Programming

Scaling of Output
To use this analog programming option, the inclination sensor must first be set to the teach-in
mode (teach 1) via RS-232 interface.
Scaling of output can be set based on a user-defined angular measuring range. The range is
defined by the 2 set points created by analog teach-in inputs SET 1 and SET 2. The analog
output is scaled to give a full measurement output (4 ... 20 mA) over the user-defined range of
measurement.
If the scaling was done correctly, the inclination sensor should give a 4 mA ... 20 mA output in
the range of measurement set between the locked positions of SET 1 and SET 2.
The scaling can also be done counterclockwise. The output is scaled according to the direction
of the sensor motion for the SET inputs. Upon scaling, the RS-232 angular output sets preset
automatically at SET 1 position.
Scaling should be done according to the following sequence of steps:
1. Set inclination sensor to teach-in mode
2. Give high signal pulse to SET 1 at the origin of the measuring range to lock the position.
Once position is locked, indicated by origin position output 4 mA, move to next step.
3. Give high signal pulse to SET 2 at the end of the measuring range.
Once position is locked, indicated by end position output 20 mA, the scaling is complete.
