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
Betrieb_Impulssperre_Test
To฀test฀the฀safe฀pulse฀disabler,฀proceed฀as฀follows:
Betrieb_Neustart_S1
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฀"FAULT"฀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฀disabler฀are฀tested.฀The฀"RUN"฀LED฀flashes.

The฀safety฀card฀switches฀to฀a฀"RUN"฀condition.฀The฀"RUN"฀LED฀is฀lit฀
continuously.
