Operating instructions
Safety-monitoring module
AES 1337
EN
The entire concept of the control system, in which the safety
component is integrated, must be validated to EN ISO 13849-2.
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 damage
to machinery or plant components cannot be excluded.
The relevant requirements of the standards ISO 14119 and
EN 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:
AES 1337
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 magnetic safety sensors on sliding, hinged
and removable safety guards.
The safety function is defined as the opening of the enabling circuits
13-14, 23-24 and 33-34 when the input S21-S22 is opened and/or when
the input S13-S14 is closed.
The safety-relevant current paths with the outputs contacts 13-14,
23-24 and 33-34 meet the following requirements under observation
of a PFH value assessment (also refer to chapter 2.5 "Safety
classification"):
– Control category 4 – PL e to DIN EN ISO 13849-1
– corresponds to SIL 3 to DIN EN 61508-2
– SILCL 3 to DIN EN 62061
To determine the Performance Level (PL) of the entire safety function
(e.g. sensor, logic, actuator) to DIN EN ISO 13849-1, an analysis of all
relevant components is required.
