SAFETY CONSIDERATION ACCORDING TO EN ISO 13849-1:2008

Example manual production line

In this case the Protective Housing have one movable guard to load/unload target

items. Mechanical construction of the guard assures that the opening of the door

causes the opening of the switch but not the exposure of the operator to the laser emis-

sion within 500 ms (eg. main door provided with switch and secondary door to access

the load/unload plate).

•

Since the severity of injury is Serious (S2), frequency is HIGH (F2) and possibility of

avoiding hazard is scarcely possible (P2), the MINIMUM REQUIREMENT as per

IEC13849-1 is PL e.

Target: PLr = e

UNIQ™

Operation is frequent/continuous (286 days per year, 9 hours per day and 20 sec-

onds per cycle).

Guard switch is connected to a safety PLC as input and UniQ™ Interlock and Enable

systems as output/input of that PLC.

Restart system must be provided.

NOTE: Considering the switching response time of I/O, it must prevent

access in a time less than 500 ms.
