2 Product description
2.1 Ordering code
This operating instructions manual applies to the following types:
SRB 207AN/1-230V
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 specications apply accordingly, provided that they correspond to
the standard version.
2.3 Destination and use
The safety-monitoring module for integration in safety circuits is desig-
ned for tting in control cabinets. It is used for the safe evaluation of the
signals of positive break position switches for safety functions or
magnetic safety sensors on sliding, hinged and removable safety
guards as well as emergency stop control devices.
Design
The safety-monitoring module has a multichannel structure. It includes
safety relays with monitored positive action contacts. The NO contacts
of the relays, which are wired in series, build the enabling contacts.
6 signalling outputs signal the position of the corresponding safety
guard.

authorised personnel in a de-energised condition.
Wiring examples: see appendix
5 Operating principle and settings
Operating principle after the operating voltage is switched on
With the guard door closed or the emergency stop command devices
unlocked, the enabling paths are closed as soon as the start button is
pushed. During the start command, the falling edge is detected, when
the contacts of the downstream relays acting on the feedback circuit
are closed.
If the safety guard is opened or the emergency-stop button is actuated,
the enabling paths of the safety-monitoring module will open.
The machine is stopped and the LED K1 and K2 will go out.
The corresponding signal output signals which guard was opened.
Inputs S11 / S12-S22 / S73 / S74;
S31 / S32-S42 / S83 / S84;
S51 / S52-S62 / S93 / S94
Safety switches or emergency stop command devices with one NC
and one NO contact must be connected to the inputs. If not all inputs
are wired, a bridge must be established between Sx1 and Sx2 of the
non-used input.
Start button/feedback circuit X1/X2
Connect start button/feedback circuit to the inputs X1 and X2 according
to the wiring diagram
Automatic start X1-X3
The automatic start is programmed by connecting the feedback circuit
to the terminals X1-X3. If no start button and no feedback circuit is
used, a bridge must be established between X1 and X3.
Outputs
Enabling paths 13-14; 23-24
NO contacts for safety functions
Signalling output Y1-Y6
0 V safety guard open / no enabling signal
24 V safety guard closed / enabling signal
Signalling output 32
Conditions of the enabling paths
The signalling outputs must not be integrated in the safety circuit.
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. Fitting of the safety monitoring module
2. Fitting and integrity of the power cable
6.2 Maintenance
In the case of correct installation and adequate use,
the safety-monitoring module features maintenance-free functionality.
A regular visual inspection and functional test, including the following
steps, is recommended:
• Check the correct xing of the safety-monitoring module
• Check the cable for damage.
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.
8 Appendix
8.1 Wiring example
The application examples shown are suggestions. They however do not
release the user from carefully checking whether the switchgear and its
set-up are suitable for the individual application
The wiring diagram is shown with guard doors closed and in a deenergised condition. Inductive loads (e.g. contactors, relays, etc.) are
to be provided with suitable interference suppression circuitry. Do not
connect additional loads to terminal S..

The connection of magnetic safety switches to the SRB
207AN/1-230V safety-monitoring module is only admitted
when the requirements of the standard EN 60 947-5-3 are
observed.
As the technical data are regarded, the following minimum
requirements must be met:
– switching capacity: min. 300 mW
– switching voltage: min. 30 VDC
– switching current: min. 10 mA
For example, the following safety sensors meet the
requirements:
– BNS 33-11z, BNS 33-11z-2063
– BNS 250-11z
– BNS 120-11-z
– BNS 180-11z
– BNS 303-11z
Also used for LED versions.
