2.4 Destination and use
The SLC 420 is a non-contact, self-testing safety guard, which is used
for the protection of hazardous points, hazardous areas and machine
accesses If one or more light beams are interrupted, the hazardous
movement must be stopped
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level

1)
Resolution = beam di beam diameter 10 mm
2)
To EN 61131-2
3)
In case of failure, the leakage current flows to the OSSD cable
The downstream control element must recognise this state as LOW
A safety PLC must detect this state
4)
The load induction generates an induced voltage during the
switch-off, which compromises the downstream components
(spark quenching element)
