4.3 Safety working modes and safety functions
4.3.1 Introduction
Each sensor can perform the following safety working modes:
l
Both (default)
l
Always access detection
l
Always restart prevention
Each safety working mode is composed of one or both of the following safety functions:
Function
Description
Access detection
The machinery is reverted into a safe status when a person enters the dangerous area.
Restart prevention The machinery is prevented from restarting if people are in the dangerous area.
4.3.2 Safety working modes
Via the Inxpect Safety application, you can select which safety working mode each sensor will perform for each
of its detection fields:
l
Both (default)
:
o
the sensor performs the access detection function when it is in normal operation (
No alarm
status)
o
the sensor performs the restart prevention function when it is in alarm status (
Alarm
status)
l
Always access detection
:
o
the sensor always performs the access detection function (
No alarm
Alarm
status)
l
Always restart prevention
:
o
the sensor always performs the restart prevention function (
No alarm
Alarm
status)
Inside the field of view of each sensor you can set up to two detection fields:
l
Detection field 1, e.g. used as alarm area
l
Detection field 2, e.g. used as warning area
The following examples show the four possible combinations of the safety working modes of LBK System BUS
and what changes if the motion is detected in detection field 1 or detection field 2.
