Parameter Setting And Alignment Of The Sensor - IFM Electronic Ecomat 100 Handbuch

Parameter setting and alignment of the sensor

The values "...Preset Value" (Idx 60x2) and "Differential ...Offset" (Idx 60x4)
affects the display of the longitudinal and lateral axis.
The value entered in "...Preset Value" immediately corrects the measured value of
the sensor cell at the instant t
play errors due to mounting (e.g. sensor zeroing). The sensor must first be bro-
ught to a defined position.
The value "Differential ...Offset" shifts the displayed value of the sensor by the
entered value. A set "...Preset Value" does not affect shifting.
Note that the resolution parameter must be set before aligning the sensor
(resolution, Idx 6000)!
Example
A boom is to work in a range of -10° to +70° and to be monitored with the incli-
nation sensor CR2102.
operating range of the boom
+70°
0°
-10°
To zero the senor the boom is first positioned to the middle of the angle range.
In this position the sensor is horizontally mounted.
To compensate for mounting errors the indexes "...Preset Value" (Idx
6012/6022) can then be set to zero for the two axes. If the boom is moved with-
out any further sensor setting, sensor values between -40°...+40° are indicated.
To obtain a display which corresponds to the mechanical angle range the display
range can be shifted by +30° to -10°...+70° via "Differential ...Offset" (Idx 60x4).
The offset which results from zeroing and shifting of the display range can be
read from the indexes 6013 and 6023.
