8.2 Testing the safe pulse disabler
The safety card meets the requirements of EN IEC 61508 up to SIL 3 and EN ISO 13849­1
up to PL e.
To achieve category SIL 3 or PL e, the operator must ensure that the function of the safe
pulse disabler is tested periodically, after 8 hours at the latest, by triggering safety functions
SS1 or STO:
} By restarting after safety functions SS1 or STO have been triggered as a condition of
operation
or
} By restarting after safety function SS1 has been triggered by the operator
To test the safe pulse disabler, proceed as follows:
1. Switch input "SS1 Activate" or "SS1 SIL3/Reset" to 0 V
} The safety card performs the safety function SS1 (Safe Stop 1) and switches to a
"STOP" condition. The "STO" LED flashes.
2. Switch input "SS1 Activate" or "SS1 SIL3/Reset" to 24 V.
} The safety card switches to a "STARTUP" condition. The device and the safe pulse dis­
abler are tested. The "RUN" LED flashes.
} The safety card switches to a "RUN" condition. The "RUN" LED is lit continuously.
