Advice On Malfunctioning And Rectification Of Errors; Maintenance And Testing; Replacement Of A Safety-Related As-Interface Slave - Siemens SIGUARD LS4-4 Anleitung

4 Check that the protective field of the LS4 AS-Interface is clear
The green LED will light up in about 20 seconds if the protective field is clear. The
LS4 AS-Interface is then in operational readiness, and the code table can be pro-
grammed into the AS-i safety monitor.
For the LS4 AS-Interface to function properly, the M12 socket X3 that is respon-
sible for the switching of the protective fields must first have been connected,
that is to say, a protective field must have been activated. For this purpose you
can use the protective field jumper plug for connection of protective field 1
(3RG7838-1DF) (see chapter 10, "Scope of standard delivery and advice on or-
dering, LS4 AS-Interface accessories").
For system integration purposes – that is to say, when the AS-Interface safety
monitor is being programmed with the code table of the safety AS-Interface sla-
ve – the protective field of the LS4 AS-Interface must not be violated.
5 The commissioning and configuration of the safety AS-Interface slave will
now be effected with the help of the configuration and diagnosis software of
the AS-Interface safety monitor.

without a PC, and the AS-Interface safety monitor subsequently reconfigured, with the
help of the SERVICE button on the AS-Interface safety monitor.
