3.2. 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.
3.3. 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 unauthorized 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.
3.4. General Information Regarding the Product
• The safety function is defined as the opening of the enabling circuits 13-14 and 23-24 and the delayed
opening of the enabling circuits 37-38 when the inputs S11-S12 and/or S21-S22 are opened.
• The safety-relevant current paths with the outputs contacts 13-14 and 23-24 meet the following require-
ments under observation of a PFH value assessment:
– 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
• The safety-relevant current paths with the outputs contacts 37-38 meet the following requirements under
observation of a PFH value assessment (also refer to chapter 2.5 “Safety classification”):
– Control category 3 – PL d to DIN EN ISO 13849-1
– corresponds to SIL 2 to DIN EN 61508-2
– SILCL 2 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.
•
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.
