5.  Configuration

5.1  Programming the slave address

The slave address is programmed through the connecting cable of the 

BNS 260 AS. Depending on the variant used, every address can be 

programmed between 1 and 31 through an M12 connector or an open 

cable extremity.

5.2  Configuration of the safety monitor

The BNS 260 AS must be configured in the monitoring device as double 

channel dependent module with start-up test.

The BNS 260 AS can be configured in the ASIMON configuration 

software with the following monitoring devices (also refer to the 

ASIMON manual):

Double channel dependent

• Optionally with startup test

• Synchronisation time typically 0.5 – 2.0 s

Double channel dependent with filtering

The use of this monitoring device is especially advantageous on safety 

guards where bounce or vibration against the mechanical stop upon 

closing is a problem.

• Optionally with startup test

• Stabilising time typically 0.5 -1.0 s

• Synchronisation time typically 5.0 – 10.0 s

The safety-monitoring module is only released after expiration of the 

stabilising time; the synchronization time always must exceed the 

stabilising time.

The configuration of the safety monitor must be tested and 

confirmed by a qualified and authorised safety expert/safety 

engineer. 

During the project planning, it must be observed that the 

length of the cable of each individual safety sensor is 

integrated in the overall length (max. 100 m without repeater) 

of the AS-Interface network.

6.  Set-up and maintenance

6.1  Functional testing

The safety function of the safety components must be tested. The 

following conditions must be previously checked and met:

1. Check the switch enclosure for damage

2. Fitting and integrity of the cable connections

3. Connect the BNS 260 AS to the AS-Interface network

4. Set the parameter outputs to "1111" (0xF) 

5.  Check the correct function of the BNS and BPS system with 

configured safety monitor

6.2  Maintenance

In case of correct installation in accordance with the above-described 

instructions, the component requires little maintenance. A regular 

visual inspection and functional test, including the following steps, is 

recommended:

1. Remove particles of dust and soiling

2. Fitting and integrity of the cable connections

Adequate measures must be taken to ensure protection 

against tampering either to prevent tampering of the safety 

guard, for instance by means of replacement actuators. 

Damaged or defective components must be replaced.

7.  Disassembly and disposal

7.1  Disassembly

The safety switchgear must be disassembled in a de-energised 

condition only.

7.2  Disposal

The safety switchgear must be disposed of in an appropriate manner in 

accordance with the national prescriptions and legislations.
