The safety card meets the requirements of EN IEC 61508 up to SIL 3
and EN ISO 13849-1 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 op-
erator

To test the safe pulse disabler, proceed as follows:
Betrieb_Neustart_S1

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 disabler are tested. The "RUN" LED flashes.
 The safety card switches to a "RUN" condition. The "RUN" LED is lit
continuously.
