AES 2135
AES 2136
1.6 Warning about misuse
In case of inadequate or improper use or manipulations of
the safety-monitoring module, personal hazards or damages
to machinery or plant components cannot be excluded. The
relevant requirements of the standard EN 1088 must be
observed.
1.7 Exclusion of liability
We shall accept no liability for damages and malfunctions resulting from
defective mounting or failure to comply with this operating instructions
manual. The manufacturer shall accept no liability for damages resulting
from the use of unauthorised spare parts or accessories.
For safety reasons, invasive work on the device as well as arbitrary re-
pairs, conversions and modifications to the device are strictly forbidden;
the manufacturer shall accept no liability for damages resulting from
such invasive work, arbitrary repairs, conversions and/or modifications
to the device.

Description
➀
5
without start-up test
6
with start-up test
Only if the information described in this operating instructions
manual are realised correctly, the safety function and there-
fore the compliance with the Machinery Directive is maintained.
2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Destination and use
The safety-monitoring modules for integration in safety circuits are
designed for fitting in control cabinets. They are used for the safe
evaluation of the signals of positive break position switches for safety
functions or magnetic safety sensors on sliding, hinged and removable
safety guards as well as emergency stop control devices.
Design
The safety-monitoring modules have a dual-channel structure. They
include two safety relays with monitored positive action contacts. The
NO contacts of the relays, which are wired in series, build the enabling
contacts.
