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 ISO 14119 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. Product description
2.1 Ordering code
This operating instructions manual applies to the following types:
AES 126
➀
No.
Option
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
therefore 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 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 as well as emergency stop control devices.
Monitoring of two safety switches, which are actuated by different safety
guards (e.g. two guard doors, which are opened independently from
one another).
Design
The safety-monitoring modules have a dual-channel structure.
They contain two safety relays with monitored positively driven
contacts. The NO contacts of the relays, which are wired in series,
build the enabling contacts.
