APPENDIX C: AREX
TM
SAFETY CONSIDERATION ACCORDING
EN ISO 13849-1:2008
The interlock connector located to the rear of the Arex
TM
laser marking system is the interface of the internal
safety-related parts of control system (SRP/CS).
With appropriate use of safety external components AND the application of the suggested
maintenance, the SRP/CS of the machine that uses Arex
TM
as components will result in Safety
Category 3, PL c.
Interlock is used to put the marking system in a safe operating mode because the action is to remove the
power to the laser source.
According to Category 3, Arex
TM
interlock is made by two separate channels, referred as INTERLOCK A and
INTERLOCK B. For a normal operation INTERLOCK A signal must be short circuited to its reference
VCC_INT_A and INTERLOCK B signal must be short circuited to its reference GND.
The opening of at least one channel causes the power removal from the internal laser source. The response
time from full laser emission to zero emission is < 5ms.
The connector’s pin-out description is:
