t of the original operating instructions)
Controls and indicators, configuration
Refer to the safety monitor manual and the configura‑
tion software manual.
Service and inspection
At least once per year, the safety officer must check
for correct operation of the AS‑Interface safety
monitor within the protective system, i.e. for reliable
switch‑off when an associated safety‑related sensor
or switch is triggered.
For this purpose, every safety‑related AS‑Interface
slave must be actuated and the switching behaviour
checked by observing the safety outputs of the AS‑In‑
terface safety monitor (see safety monitor manual).
The safety monitor must be replaced if it malfunc‑
tions or is damaged.
The monitor can be replaced with an equivalent unit
without the need for reconfiguration (see safety
monitor manual).
Liability coverage is voided under the
following conditions
f
if instructions are not followed
f
non‑compliance with safety regulations
f
installation and electrical connection not performed
by authorized personnel
f
non‑implementation of functional checks.
