8.3 Preset input signal
The beginning of the magnetic tape does not represent the
measured position 0, but rather the zero point can be at
any desired position within or outside of the magnetic tape.
Crossing the zero point causes a position jump (overrun)
and the Error bit is set. Therefore first set the appropriate
measuring range before operating.
To set the measuring range the sensor must be moved to
the start of the measuring range. The Preset connection is
made to supply voltage for at least 20 ms. The current
position is set to 10 mm ±1 mm.

Example for measuring range adjustment
The Preset connection is suitable only for approximate
setting of the start position. To set the position with greater
accuracy you must use the Configuration Tool (see Section
11.8 on page 45).
