Setting PNP or NPN output
Standard configuration (factory setting): PNP
1. To change, hold down the + and – keys together for 10 s:
If the time delay is enabled, the DELAY LED will go
out after 2 s and come on again after 10 s.
This completes the change.
If the time delay is disabled, the DELAY-LED will
come on after 2 s and go off again after 10 s.
This completes the change
2. Do not release the keys until the DELAY-LED
has
responded as described under step 1.
The KEYLOCK-LED indicates the setting:
1x flashing: PNP output active
2x flashing: NPN output active
Setting the switching threshold manually
The switching threshold can be adjusted to the application.
The blinking pattern on the segment display indicates by
how much the switching threshold deviates from the
threshold output value. The blinking frequency is proportio-
nal to the difference from the initial treshold vlaue.
1. Press the + or – key:
The first 3 LEDs from the left turn on.
To increase the switching threshold, press the + key
multiple times. The segment display moves to the right.
1 to 10 pressures:
11 to 20 pressures:
To reduce the threshold value, press the – key multiple
times. The segment display moves to the left.
1 to 10 pressures:
11 to 20 pressures:
2. To store the current threshold value, press the SET key
or wait 30 s.
Setting Remote control (REMOTE SET)
With remote control enabled, the SET key is disabled. The
SET function is triggered by a signal applied to Pin 5 (Fig. 5).
SET functions using the Remote cable:
– "Press SET key" function:
Connect cable to 10...30 V DC.
– "Do not press SET key" function:
Connect cable to 0 V DC or leave unconnected.

Turning time delay (DELAY) on/off
Standard configuration (factory setting): Output delay off.
To enable slower sensor interfaces to detect shorter pulses
as well, turn on the output delay. This increases the mini-
mum length of the output signal to 20 ms.

Turning on the output delay
1. Press + and – contemporaneously for 2 sec. until the
Delay LED turns on.
Turning off the output delay
1. Press + and – contemporaneously for 2 sec. until the
Delay LED turns off.

Settings are correct, sensor is ready
Fast blinking Output short circuit or
output current exceeded
Slow blin-
king
The settings or the acquisition of data are
incorrect, the sensor is not operative.
Causes:
– The contrast between the marking
and the background is insufficient
– The acquisition of the new marking or
of the new background is incorrect or
not stored
