SRB-E-301MC20No. Option Description
➀
CC Plug-in cage clamps: single wire (rigid)
(Signal contact 41/42, normally-closed contacts in series)
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-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 safety
sensors for safety functions on sliding, hinged and removable safety
guards as well as emergency stop control devices, safety solenoid
switches and AOPD's.
The safety function is defined as deactivating outputs 13/14, 23/24,
33/34 when inputs S12 and/or S22 are opened. Taking account of a
PFH value assessment, the safety-relevant current paths meet the
following requirements (see also chapter 2.6 “Safety classification”):
• Control category 4 - PL e to ISO 13849-1
• SIL 3 to IEC 61508
• SILCL 3 to EN 62061
➀
Plug-in screw clamps: single wire (rigid)
or fine wire (flexible): 0.2 … 2.5 mm²;
fine wire with ferrule: 0.25 … 2.5 mm²
or fine wire (flexible): 0.2 … 1.5 mm²;
fine wire with ferrule: 0.25 … 1.5 mm²
➀
Plug-in screw clamps: single wire (rigid)
or fine wire (flexible): 0.2 … 2.5 mm²;
fine wire with ferrule: 0.25 … 2.5 mm²
or fine wire (flexible): 0.2 … 1.5 mm²;
fine wire with ferrule: 0.25 … 1.5 mm²
Only if the action described in these operating instructions is
carried out correctly will the safety function be safeguarded,
including compliance with the Machinery Directive.
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.

a bridge.
Not admitted without additional measure due to the risk of
gaining access by stepping behind!
Within the meaning of IEC/EN 60204-1 paragraph 9.2.5.4.2
the operating mode "automatic start" is only restrictedly admissible. In particular, any inadvertent restart of the machine

8. Set-up and maintenance
8.1 Commissioning
The safety relay module features protection class IP54 for installation
in a switch cabinet.
The safety relay module is delivered ready for operation.
Application 1 is preset in the factory.
8.2 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 sensor technology and
their influence on the safety-monitoring module and the downstream
actuators
The safety relay module features self-test functions.
If a fault is detected, the system adopts a safe mode and leads,
if necessary, to undelayed deactivation of all safety outputs.
8.3 Behaviour in the case of faults
In the event of a fault the following procedure is recommended:
1. Identify faults according to chapter 6.1.
2. Rectify the fault if it is described in the table.
If fault could not be rectified, please contact the manufacturer.
8.4 Setting report
This report regarding the setting of the device must be completed
accordingly by the customer and enclosed in the technical
documentation of the machine.
The setting report must be available whenever a safety check is
performed.
8.5 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 13849-1) or SIL 2 with HFT (hardware
fault tolerance) = 1 (according to IEC 62061).
Damaged or defective components must be replaced.
9. Disassembly and disposal
9.1 Disassembly
The safety-monitoring module must be disassembled in a de-energised
condition only.
9.2 Disposal
The safety-monitoring module must be disposed of in an appropriate
manner in accordance with the national prescriptions and legislations.
