Safety instructions
Read the instruction manual carefully before commissioning!
Connection, assembly, adjustment, and commissioning may only be carried out by qualified personnel.
The device is not a safety component according to the EU Machinery Directive. If there is a direct impact on personal safety,
the use of this product is prohibited!
Use in outdoor areas is not permitted.
Attention: Use of controls or adjustments or performance of procedures other than those specified may result in hazardous
radiation exposure.
Laser protection class 1 according to IEC 60825-1
Wavelength 655nm, frequency 62.5kHz, pulse width 4ns, limit value pulse <1.56W
Conforms to 21 CFR 1040.10 and 1040.11 except for the deviations according to Laser Notice No. 50 of 24 June
2007.
Intended use
The sensor is used for optical contactless detection of objects.
Mounting
Attach the sensor with a suitable mounting bracket.
Connection
Plug on the cable socket in a de-energised condition and screw it tight. Connect the cable according to the connection diagram
on page 2.
The sensor automatically detects whether the load at the switching output is PNP or NPN. Load voltage and supply voltage
must come from one voltage source, a parallel connection of two sensors is not permitted!
Setting
The laser scanner has an analog and a switching output that can be set independently of each other.
Analog output: The two teach points mark the beginning and end of the measuring range and scale the analog output.
Teach 1 = 4mA, Teach 2 = 20mA.
Switching output:Die beiden Teachpunkte kennzeichnen Anfang und Ende des Schaltfensters.
Setting modes: Teach sequence and object distance determine the characteristic curve of the analog output and the window
width of the switching output.
Control input
The sensor has a control input on PIN 5 (gray wire of the cable socket) with the following functions:
open: Teach buttons active
connection to L-: Teach-buttons locked
connection to L+: Teach-input active
Maintenance
The laser scanner is maintenance-free. It is recommended to clean the optical surfaces and to check screw connections and
plug connections at regular intervals.

Setting modes
1) Forced reflector operation: all non-transparent objects in zone A are reliably detected.
Reset to factory setting
1. Disconnect the device from the supply voltage.
2. Press one of the keys QA or Q.
3. Switch the supply voltage back on while keeping the keys pressed. The green LED is blinking.
4. Press and hold the buttons for more than 10s until both LEDs are blinking 3x simultaneously.
5. The factory setting is restored.
