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 when safety switchgear is
used. The relevant requirements of the standard ISO 14119
must be observed.
1.7 Exclusion of liability
We shall accept no liability for damages and malfunctions resulting from

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.

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 sensor BNS 16 is designed for application in safety circuits
and is used for monitoring the position of movable safety guards to
ISO 14119 and IEC 60947-5-3. To actuate the safety sensors, only the
BPS 16 actuators can be used, conventional magnets are not suitable.
The safety switchgears are classified according to
ISO 14119 as type 4 switching devices.
To ensure a safe switch-off, the distance between the safety sensor and
the actuator must be at least 18 mm (sar) or higher (opening width of the
safety guard).
For the BNS 16-12ZLR, the safe condition is only obtained, when the
left and the right actuator are located in front of the safety sensor.
The safety switches are used for applications, in which the hazardous
situation is terminated without delay when the safety guard is opened.
Only the entire system consisting of the safety sensor (BNS 16), the
actuator (BPS 16) and the safety-monitoring module (AES, SRB) meets
the requirements of the standard IEC 60947-5-3.
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level.
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.

3.3 Axial misalignment
A horizontal and vertical misalignment of the safety sensor and the
actuator is tolerated. The possible misalignment depends on the
distance of the active surfaces of the sensor and the actuator. The
sensor remains active within the tolerance range.
The specified switching distances refer to opposedly mounted safety
sensors and actuators.

In combination with a safety-monitoring module, the wires of the safety
sensor must be wired in the following way:
NO contact: S13-S14 at the "NO input" of the
safety-monitoring module
NC contact: S21-S22 at the "NC input" of the
safety-monitoring module
NO contact: only for BNS 16-12Z. -ST.:
S31-S32 can be used for signalling purposes.
In this way, the coding of the safety sensor is ensured.
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by
means of a suitable circuit.
Information for the selection of suitable safety-monitoring
modules can be found in the Schmersal catalogues or in
the online catalogue on the Internet: www.schmersal.net.
Connecting multiple BNS 16 safety sensors to one AES safety-monitoring
module is technically possible. To connect multiple safety sensors (check if
authorised!), their NO contacts are wired in parallel and their NC contacts
in series. The Protect-IE-11 input expander module can be used to connect
up to 4 safety sensors as NC/NO version.

5. Set-up and maintenance
5.1 Functional testing
The safety function of the safety components must be tested. The
following conditions must be previously checked and met:
1. Fitting of the sensor and the actuator
2. Fitting and integrity of the power cable
3. The system is free of dirt and soiling
(in particular metal chips)
5.2 Maintenance
In the case of correct installation and adequate use, the safety sensor
features maintenance-free functionality.
A regular visual inspection and functional test, including the following
steps, is recommended:

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.
6. Disassembly and disposal
6.1 Disassembly
The safety switchgear must be disassembled in a de-energised
condition only.
6.2 Disposal
The safety switchgear must be disposed of in an appropriate manner in
accordance with the national prescriptions and legislations.
