Important information
DANGER
Hazard due to lack of effectiveness of the protective device
The dangerous state may not be stopped in the event of non-compliance.
The same safety level is required for the safety-related parts of the control which switch
the active protective field as for the safety function. In many cases, this is PL
d as per
ISO
13849-1 or SIL2 as per IEC
62061.
•
Use the same earthing method for all devices that are electrically connected to the
safety laser scanner.
•
Voltage must be supplied in accordance with SELV/PELV (IEC 60204-1) for all
devices that are electrically connected to the safety laser scanner.
•
All devices connected to a local input or output of the safety laser scanner must
be in the same SELV/PELV circuit as the safety laser scanner.
Prerequisites
•
Position-dependent switching is carried out by 2 independently wired signal sour‐
ces, such as 2 independent position switches.
•
Manual switching that depends on the operating mode is carried out using a
suitable manual control switch.

Static control inputs
Overview
The static control inputs support the following evaluation methods:
•
Complementary analysis
You can define the switching criteria for the monitoring cases (
).
Complementary analysis
A static control input consists of 2 channels. To switch correctly, one channel must be
switched inversely to the other. The following table shows which status the static control
input’s channels must have to define logical input condition 1 and 0 at the relevant
control input.

In antivalent evaluation, the 2 channels of each static control input must always be
inverted, even if the status of a control input in a monitoring case is random. If it is not
inverted, all safety outputs switch to the OFF state and the device displays a fault.
