Operating instructions
Safety-monitoring module
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 re-
pairs, 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:
SRB 031LC/0.6 sec
Factory-set drop-out delay: 0.6 seconds
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 Destination and use
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 or magnetic
safety sensors for safety functions on sliding, hinged and removable
safety guards as well as emergency stop control devices and AOPD's.
The safety function is defined as the delayed opening of the enabling
circuits 17-18, 27-28 and 37-38 when the inputs S11-S12 and/or
S11-S22 are opened. The safety relevant current paths with the output
contacts 17-18, 27-28 and 37-38 meet the following requirements under
observation of a B
value assessment (also refer to "Requirements to
10d
DIN EN ISO 13849-1"):
– control category 3 – PL d to DIN EN ISO 13849-1
– corresponds to SIL 2 to DIN EN 61508-2
– corresponds to SILCL 3 to DIN EN 62061
(corresponds to control category 4 to DIN EN 954-1)
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.
