Switching off the laser diodes during downtime can increase their service lives. The
time span from deactivating the MF1 to renewed measured value output is max. 45 ms.
7.1.13
MF1 – Preset submenu
In this submenu, you can parameterize the MF1 as a switching input to activate the
static preset. This makes it possible to automatically adjust the measured distance
value to a reference value (preset) known to the system during commissioning, mainte‐
nance or device replacement.
For the static preset described here, the time for adopting the reference value in the
device is determined by activating MF1. The distance value measured at this time is
automatically provided with an offset and therefore adjusted to the reference value. The
following applies: Offset = Preset – measured distance value.
As an alternative to MF1, presetting can be performed via the fieldbus interface
"Preset – moving to initialization position", page 79
.
NOTE
When activating the preset, the output of measured values of the distance sensor will
be temporarily unavailable. We recommend carrying out the preset while the machine
is at a standstill or running at very low speeds. The maximum activation number is
typically around 10,000 cycles. The offset value calculated when activating the preset
is permanently saved in the device.

Parameter
Description
sPrset
Assign reference value. When activating the MF1, the reference value is
adopted and the associated offset calculated.
Options
•
–600,000 … + 300,000 [mm].
Factory setting
•
0 [mm]
NOTE
Because the display can only handle six digits, only negative values down to
–99999
can be input.
Via SOPAS ET or an existing fieldbus interface, the entire value range is
available as input. For values smaller than
–99999
, the highest decimal
place is truncated in the display.
Setting the preset
1.
Select the
Preset
function for multifunctional input MF1.
2.
Enter the desired initialization value for the
Preset
parameter.
3.
Drive the vehicle to the initialization position.
4.
To do so, activate multifunctional input In1 / MF1, for exampling using a proximity
switch, a photoelectric sensor or a switch.
✓
The output value of the device corresponds to the set value for
Preset
at the
initialization position.
