Mounting of the electronic display
For switchboard installation the recommended dimensions of IEC 61554 shall
be applied.
Mounting of the magnetic sensor
The sensor senses the incremental travel information of the MB500/1 magnetic
tape (linear) or of the MR500 magnetic rings (rotary).
The magnetic sensor, L versions, is mounted by means of the two attached M3
screws via the ø3.1 mm through holes.
Mounting the magnetic tape
Stick the magnetic tape level to the mounting surface or the distance to be
measured. Unevenness impairs measuring accuracy.
Mounting steps:
