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 BNS 36 safety sensor 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 36-1 (-2750) or BPS 260-2 (-2750) actuators can be used.

The safety sensors are used for applications, in which the hazardous
situation is terminated without delay when the safety guard is opened.

The safety switchgears are classified according to
ISO 14119 as type 4 switching devices.

Only the entire system consisting of the safety sensor (BNS 36), the
actuator (BPS 36) 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. Mounting

3.1 General mounting instructions

During fitting, the requirements of ISO 14119 must be
observed.

• Fitting is only authorised in a de-energised condition.

• Do not use the sensor and the actuator as a mechanical backstop.

• Any mounting position, provided that the active surfaces are opposite.

• Do not subject the safety sensor and actuator to extreme vibrations
and shocks.

To avoid any interference inherent to this kind of system and any reduc­tion of the switching distances, please observe the following guidelines:

• Ensure the safety sensor is mounted on a flat surface

• Do not install the safety sensor and the actuator in strong magnetic

fields

• If possible, do not mount the sensor and the actuator on ferromagnetic

material. A non-magnetic spacer at least 5 mm thick or the original
spacer must be used. The use of non-magnetic fixing screws is
recommended also.

• Keep away from metal chips

• The mounting distance between two sensors should always be at

least 50 mm

Safety sensor and actuator must be permanently fitted to the
safety guards and protected against displacement by suitable
measures (tamperproof screws, gluing, drilling of the screw
heads).

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 surface 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.

4. Electrical connection

4.1 General information for electrical connection

The electrical connection may only be carried out by
authorised personnel in a de-energised condition.

The safety sensors must be wired in accordance with the wire colours
or the pin configuration.

4.2 Contact variants

The contact position shows the actuated sensor function when the safe­ty guard is closed. For safety sensors with LED, the LED is illuminated
when the safety guard is closed. The contact configurations of the
versions with or without LED are identical.

Safety contacts: S21-S22 and S11-S12 or S13-S14
Signalling contact: S31-S32

The numbers between brackets indicate the PIN configuration of the
versions with integrated connector; indication of the wire colours for the
version with cable.

3.4 Adjustment

Recommended Adjustment

Align the safety sensor and actuator at a distance
of 0.5 x sao.

Align the central markings of the safety sensor and the actuator with
each other. The LED can only be used as rough setting tool. The cor­rect functionality of both safety channels must be checked by means of
the connected safety-monitoring module.

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 36-11Z safety sensors to one AES safety­monitoring 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 or -02 or
PROTECT-PE-11 (-AN) or -02 input expander module can be used to
connect up to 4 safety sensors with NC/NC or NC/NO contacts.

Safety sensors equipped with LED's shall not be wired in series, except
for the Protect-IE or PROTECT-PE input expander module. As a result
of this, the luminosity of the LED's would considerably decrease and the
voltage could drop below the minimum input voltage of the downstream
safety-monitoring module.

5. Set-up and maintenance

5.1 Functional testing

The safety function of the safety sensor 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:

• Check of the safety function

• Check the fitting of the sensor and the actuator.

• Remove possible metal chips.

• Check the cable for damage.

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 sensor must be disassembled in de-energised
condition only.
