1)
Detection capability is reduced with moving test body Further
information available from technical sales department
2)
To IEC 61131-2
3)
In case of failure, OSSD leakage current
The downstream control element must recognise this state as LOW
A safety PLC must detect this state
4)
The load inductivity generates an induced voltage during the switch-off,
which compromises the downstream components (spark quenching
element)
2.6 Response time (reaction time)
The response time depends on the number of light beams and the

2.8 Modes of operation / functions
All of the described functions can be executed without safety monitoring
modules A command unit is needed for diagnosis and function
selection (button, adapter cable, see section on parameterisation)
The system has the following operating modes:
• Protection mode with automatic start after release of the protection
field (factory setting)
• Protection mode with restart interlock
The system has the following functions:
• Parameter setting with selection of beam coding and type of
protection mode On SLB450, the integrated heater can be activated
and deactivated
• Alignment aid, diagnosis
• Heater with temperature control (only SLB450)
Factory setting
When delivered (factory setting) automatic mode is active On SLB450
with integrated heater, the heater/temperature control is active in
delivered state
2.8.1 Protection mode with automatic (automatic)
In automatic mode the safety switching outputs
(OSSD) are switched to the ON state if the protection zone is
uninterrupted This is done without any authorization from a command
device
This operating mode initiates an automatic restart of the machine if the
protection zone is not interrupted
This operating mode may only be chosen in conjunction
with the restart interlock (manual reset) of the machine
This operating mode must not be chosen, when persons
can step behind the protection field
