1.6 Warning about misuse
In case of inadequate or improper use or manipulations of
the safety-monitoring module, personal hazards or damage
to machinery or plant components cannot be excluded.
The relevant requirements of the standards ISO 14119 and
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
resulting from the use of unauthorised spare parts or accessories.
For safety reasons, invasive work on the device as well as arbitrary
repairs, 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

2. Product description
2.1 Ordering code
This operating instructions manual applies to the following types:
SRB 200X2
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-
14 and 23-24 when the inputs S11 - S12 and/or S11 - S22 are opened
or when the supply voltage A1 is disconnected. The safety-relevant
current paths with the output contacts 13-14 and 23-24 meet the
following requirements under observation of a B10D value assessment
(also refer to "Requirements of DIN EN ISO 13849-1"):
– Control category 4 - PL e to DIN EN ISO 13849-1
– SIL 3 to DIN EN 61508-2
– SILCL 3 to DIN EN 62061 (meets the requirements of 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.
The entire concept of the control system in which the safety
component is integrated, must be validated to the relevant
standards.

4.1 General information for electrical connection
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.

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.
7.2 Disposal
The safety-monitoring module must be disposed of in an appropriate
manner in accordance with the national prescriptions and legislations.

• The safety-monitoring module is activated by the 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.
