Operating instructions
Safety-monitoring module
1.6 Warning about misuse
In case of inadequate or improper use or manipulations of
the safety-monitoring module, personal hazards or damage
to machinery or plant components cannot be excluded.
The relevant requirements of the standards ISO 14119 and
ISO 13850 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.
The safety-monitoring module must only be used when the enclosure is
closed, i.e. with the front cover fitted.
2. Product description
2.1 Ordering code
This operating instructions manual applies to the following types:
SRB 207AN
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 module for integration in safety circuits is
designed for fitting in control cabinets. It is 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. Up to 6 safety guards can be
monitored by means of the AES 207AN safety-monitoring module.
Design
The safety-monitoring module has a multichannel structure. It includes
safety relays with monitored positive action contacts. The NO contacts
of the relays, which are wired in series, build the enabling contacts. 6
signalling outputs signal the position of the corresponding safety guard.
The entire concept of the control system in which the safety
component is integrated, must be validated to the relevant
standards.
