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 Purpose
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 opening of the enabling circuits
13-24 and 33-44 when the inputs S31-S32 and/or S41-S42 (S43-S44)
are opened and as the opening of the enabling circuits 13-14, 13-24,
33-34 and 33-44 when the inputs S12 and/or S22 are opened. The
safety-relevant current paths with the output contacts 13-14, 13-24,
33-34 and 33-44 fulfil the following requirements in consideration of a
B10D value (see also "Details in terms of ISO 13849-1“):
– Category 4 – PL e in accordance with ISO 13849-1
– Complies with SIL 3 in accordance with IEC 61508-2
– Complies with SILCL 3 in accordance with EN 62061
To determine the Performance Level (PL) to ISO 13849-1 of the entire
safety function (e.g. sensor, logic, actuator), an assessment of all
relevant components is required.
The entire concept of the control system in which the safety
component is integrated, must be validated to the relevant
standards.

As far as the electrical safety is concerned, the protection
against unintentional contact of the connected and therefore
electrically interconnected apparatus and the insulation of the
feed cables must be designed for the highest voltage, which
can occur in the device.
The electrical connection may only be carried out by
authorised personnel in a de-energised condition.
Wiring examples: see appendix
To avoid EMC disturbances, the physical ambient and
operational conditions at the place where the product is
installed, must meet the provisions laid down in the paragraph
"Electromagnetic Compatibility (EMC)" of EN 60204-1.

Due to the operating principle of the electronic fuse,
the customer must check that no hazard is caused by
an unexpected restart in circuits without reset button
(automatic reset).
6. Set-up and maintenance
6.1 Functional testing
The safety function of the safety-monitoring module must be tested.
The following conditions must be previously checked and met:
1. Correct fixing
2. Check the integrity of the cable entry and connections
3. Check the safety-monitoring module's enclosure for damage.
4. Check the electrical function of the connected sensors and their
influence on the safety-monitoring module and the downstream
actuators
6.2 Maintenance
A regular visual inspection and functional test, including the following
steps, is recommended:
1. Check the correct fixing of the safety-monitoring module
2. Check the cable for damages
3. Check electrical function
If a manual functional check is necessary to detect a possible
accumulation of faults, then this must take place during the
intervals noted as follows:
• at least every month for PL e with category 3 or category
4 (according to ISO 13849-1) or SIL 3 with HFT (hardware
fault tolerance) = 1 (according to IEC 62061);
• at least every 12 months for PL d with category 3
(according to ISO 13489-1) or SIL 2 with HFT (hardware
fault tolerance) = 1 (according to IEC 62061).
Damaged or defective components must be replaced.
7. Disassembly and disposal
7.1 Disassembly
The safety-monitoring module must be disassembled in a de-energised
condition only.
Push up the bottom of the enclosure and hang out slightly tilted
forwards.
7.2 Disposal
The safety-monitoring module must be disposed of in an appropriate
manner in accordance with the national prescriptions and legislations.

External reset button (Fig. 6)
• The reset button for switch-off level 1 is wired to terminal X1.
Activation is by reset (after release) of the reset button (= detection of
the trailing edge). Faults in the reset button, e.g. welded contacts or
manipulations which could lead to an inadvertent restart, are detected
in this configuration and will result in an inhibition of the operation.
• The reset button for switch-off level 2 is wired to terminal X2. The
manual start or the activation of the module occurs when the button is
pressed (not when it is released!).
• The external reset button is integrated in the feedback circuit in series.
* Automatic start at switch-off level 2: the reset button jmust be
replaced with a bridge.

Automatic start (see Fig. 7)
• The automatic start is programmed by connecting the feedback
circuit to the terminals X1 (referring to the switch-off level 1) and X2
(referring to the switch-off level 2). Feedback circuits are not required
to be replaced by a bridge.
Not admitted without additional measure due to the risk of
gaining access by stepping behind!
Within the meaning of EN 60204-1 paragraph 9.2.5.4.2, the
operating mode "automatic start" is only restrictedly admissi-
ble. In particular, any inadvertent restart of the machine must
be prevented by other suitable measures.
* An external reset button for a manual start can be installed in switch-
off level 2.

The connection of magnetic safety switches to the safety-
monitoring modules is only admitted when the requirements
of the standard IEC 60947-5-3 are observed.
As the technical data are regarded, at least the following
requirements must be met:
Switching capacity: min. 3 W
Switching voltage: min. 30 VDC
Switching current: min. 10 mA
For example, the following safety sensors meet the
requirements:
BNS 33-11z, BNS 33-12z-2063, BNS 33-11z-2063
BNS 250-11z
BNS 120-11z
BNS 180-11z
BNS 303-11z
BNS 36-11z
BNS 260-11z
Caution! When sensors with LED are wired in the control
circuit (protective circuit), the following rated operating voltage
must be observed and respected:
– 24 VDC with a max. tolerance of –5%/+ 20 %
Otherwise availability problems could occur, especially in
series-wired sensors, where a voltage drop in the control
circuit is triggered by LEDs for instance.
