Operating instructions
Safety-monitoring module
AZR 31S1
EN
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 improper use or manipulation of the safety switch-
gear, personal hazards or damages to machinery or plant
components cannot be excluded. The relevant requirements
of the standards EN 1088 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 result-
ing 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.
The safety-monitoring module must only be used when the enclosure is
closed, i.e. with the front cover fitted.

This device is designed as dual-channel fail-safe standstill
monitor for monitoring the sensorless motor standstill (no
adjustment required). The nominal motor voltage may amount
up to 400 VAC ±10%.
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 evalu-
ation of the voltage at the inputs L1, L2 and L3
The safety function is defined as the opening of the enabling contacts
13-14, 23-24 and 33-34 when voltage is detected at the inputs L1, L2
and L3. The safety-relevant current paths with the output contacts
13-14, 23-24 and 33-34 meet the following requirements under
observation of a B
10d
value assessment (also refer to "Requirements
to DIN EN ISO 13849-1"):
– control category 4 – PL e to DIN EN ISO 13849-1
– corresponds to SIL 3 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.
