8.3  Connection of external contactors K1 and K2 

External contactors can be integrated in the automatic or manual operating mode. 

The contactors have to be connected in series between the supply voltage and pin 

4 of the receiver (

→ 8 Operating modes

 / table, fig. B ).

With manual function a start button has additionally to be switched in series (

→ 8 

Operating modes / table, fig. D).

8.4  Test function

For the test function the photoelectric safety sensors can e.g. be tested by a 

process control system or a control module (

→ 7.1

 Table

 

Configuration protected 

area width). 
The test pulse interrupts the light emission by the transmitter and the outputs carry 

a 0 signal (

→ 10.1

 Switching states of the outputs).

The minimum duration of the test command is 4 ms.

8.4.1  Internal test function

Type 2 safety light curtains / light grids have an automatic internal test function 

to detect faults. An internal test is performed at an interval of ≤ 5 s and with each 

change from "protected area interrupted" to "protected area clear".
Type 4 safety light curtains / light grids continuously perform internal tests. The 

faults are detected within the response time of the respective model leading to 

switch-off (response times 

→ 12 Technical data

).
