The safety relay meets the requirements of EN60947-5-1, EN60204-1 and VDE0113‑1
and may be used in applications with light grids.
The following is deemed improper use in particular:
}Any component, technical or electrical modification to the product
}Use of the product outside the areas described in this manual
}Use of the product outside the technical details (see Technical details [ 12]).
NOTICE
EMC-compliant electrical installation
The product is designed for use in an industrial environment. The product
may cause interference if installed in other environments. If installed in other
environments, measures should be taken to comply with the applicable
standards and directives for the respective installation site with regard to in-
terference.
Safety regulations
Safety assessment
Before using a unit it is necessary to perform a safety assessment in accordance with the
Machinery Directive.
Functional safety is guaranteed for the product as a single component. However, this does
not guarantee the functional safety of the overall plant/machine. In order to achieve the re-
quired safety level for the overall plant/machine, define the safety requirements for the
plant/machine and then define how these must be implemented from a technical and organ-
isational standpoint.
Use of qualified personnel
The products may only be assembled, installed, programmed, commissioned, operated,
maintained and decommissioned by competent persons.
SE-SR2
Operating instructions SE-SR2
826002433-EN-Rev.C 6
A competent person is a qualified and knowledgeable person who, because of their train-
ing, experience and current professional activity, has the specialist knowledge required. To
be able to inspect, assess and operate devices, systems and machines, the person has to
be informed of the state of the art and the applicable national, European and international
laws, directives and standards.
It is the company’s responsibility only to employ personnel who
}Are familiar with the basic regulations concerning health and safety / accident preven-
tion,
}Have read and understood the information provided in this description under "Safety"
}Have a good knowledge of the generic and specialist standards applicable to the spe-
cific application.
Warranty and liability
All claims to warranty and liability will be rendered invalid if
}The product was used contrary to the purpose for which it is intended
}Damage can be attributed to not having followed the guidelines in the manual
}Operating personnel are not suitably qualified
}Any type of modification has been made (e.g. exchanging components on the PCB
boards, soldering work etc.).
Disposal
}In safety-related applications, please comply with the mission time TM in the safety-re-
lated characteristic data.
}When decommissioning, please comply with local regulations regarding the disposal of
electronic devices (e.g. Electrical and Electronic Equipment Act).
For your safety
The unit meets all the necessary conditions for safe operation. However, please note the
following:
}Note for overvoltage category III: If voltages higher than low voltage (>50 VAC or >120
VDC) are present on the unit, connected control elements and sensors must have a
rated insulation voltage of at least 250 V.

Unit features
}Positive-guided relay outputs:
– 3 safety contacts (N/O), instantaneous
– 1 auxiliary contact (N/C), instantaneous
}Connection options for:
– Start button
– Light grids
}LED display for:
– Supply voltage
– Switch status of the safety contacts
}No galvanic isolation between UB and input circuit
}Plug-in connection terminals
Safety features
The safety relay meets the following safety requirements:
}The circuit is redundant with built-in self-monitoring.
}The safety function remains effective in the case of a component failure.
}The correct opening and closing of the safety function relays is tested automatically in
each on-off cycle.

Function Description
The relay SE-SR2 provides a safety-oriented interruption of a safety circuit. When operating
voltage is supplied the "POWER" LED will light up. The unit is ready for operation when the
start circuit S12-S34 is closed.
}Input circuit is closed (e.g. light grid not interrupted):
– The LEDs "CH.1" and "CH.2" are lit.
– Safety contacts 13-14, 23-24 and 33-34 are closed, auxiliary contact 41-42 is open.
The unit is active.
}Input circuit is opened (e.g. light grid interrupted):
– The LEDs "CH.1" and "CH.2" go out.
– Safety contacts 13-14, 23-24 and 33-34 are opened redundantly, auxiliary contact
41-42 is closed.
Operating modes
}Dual-channel operation without detection of shorts across contacts: Redundant input
circuit, detects SE-SR2
– earth faults in the start and input circuit,
– short circuits in the input circuit.
}Automatic start: Unit is active once the input circuit has been closed.
}Manual start without control: Unit is active once the input circuit and the start circuit are
closed.
}Manual start with control: Unit is active once the input circuit is closed and once the
start circuit is closed after the waiting period has elapsed (see Technical
details [ 12]).
}Increase in the number of available contacts by connecting contact expander modules
or external contactors/relays.

Installation
}The unit should be installed in a control cabinet with a protection type of at least IP54.
}Use the notch on the rear of the unit to attach it to a DIN rail (35mm).
}When installed vertically: Secure the unit by using a fixing element (e.g. retaining
bracket or end angle).
Wiring
Please note:
}Information given in the "Technical details [ 12]" must be followed.
}Outputs 13-14, 23-24, 33-34 are safety contacts; output 41-42 is an auxiliary contact
(e.g. for display).
}Auxiliary contact 41-42 shouldnot be used for safety circuits!
}To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 12]).
}Calculation of the max. cable length lmax in the input circuit:
Rlmax
Rl / km
Imax =
Rlmax = max. overall cable resistance (see Technical details [ 12])
Rl/km = cable resistance/km
}Use copper wire that can withstand 60/75°C.
}Do not switch low currents using contacts that have been used previously with high cur-
rents.
}Sufficient fuse protection must be provided on all output contacts with capacitive and in-
ductive loads.
}The power supply must comply with the regulations for extra low voltages with protect-
ive electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410.
}Ensure the wiring and EMC requirements of EN 60204-1 are met.

E-STOP pushbutton is released. Use external circuit measures to prevent
an unexpected restart.
