EN
There are no residual risks, provided that the safety instructions as well
as the instructions regarding mounting, commissioning, operation and
maintenance are observed.
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
repairs, 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.

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 Purpose
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.
AES 1102
Monitoring one safety switch or multiple safety switches in series-
parallel circuits.
The number of connected safety switches is restricted by the contract
transition resistance and the conduction resistance. This overall
resistance must not exceed 300 Ω. For magnetic safety sensors with
LED, the brightness of the LED's reduce as the amount of guard doors
opened increases.
AES 1112
Monitoring of two safety switches, which are actuated by different safety
guards (e.g. two guard doors, which are opened independently from
one another). The green LED indicates that the authorised operation.
