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 7112.
➀
No. Option Description
➀
1 110 VAC
2 230 VAC
3 24 VAC
Only if the information described in this operating instructions
manual are realised correctly, the safety function and therefo-
re 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.
Design
The AES 7112 has a triple redundant structure for monitoring guard
doors. A first fault can lead to a failure of one of the three channels,
whereby the two other channels maintain their safe function. In this
system "position switches for safety functions", the requirements of IEC
60947-5-3 are only met, when the combination of safety sensor and
coded magnet plus safety-monitoring module is used. A safety sensor
alone does not meet the requirements of this standard.
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.
