Parameter Descriptions
7.2.1.
Preselection’s
Preselection parameters are not relevant for model DZ266
These parameters assign the desired switching points to the relays/outputs. The preselection’s
use the same engineering units as the display of the actual speed (see Display-Menu).

(*) With settings HTL / NPN the input terminals are connected to the power supply voltage of
the unit (+24 V) via internal pull-up resistors. For this reason it is advisable to first set the
encoder properties correctly, prior to connecting TTL encoders to the unit.
Setting HTL / NPN is also suitable for use with NAMUR (2-wire) proximities.
(connect the positive wire of the sensor to the input terminal and the negative wire to GND)
