INFORMATION
This gives advice on applications and provides information on special fea-
tures.
Safety
Intended use
Safety function of safety switch:
}2 safety outputs supply a high signal each when the corresponding input is high and the
actuator is in the switch's response range.
The safety gate system meets the requirements in accordance with
}EN 60947-5-3: PDDB with the corresponding actuator PSEN sl0.5 or PSEN sl0.5fm
(see Technical details: System with normal actuator [ 27], System with free-moving
actuator [ 30])
}EN 62061: SIL CL 3
}EN ISO 13849-1: PL e and Cat. 4
}EN ISO 14119: Coding level High, Type 4
}The safety switch may only be used with the corresponding actuator (see Technical De-
tails: System with normal actuator [ 27], System with free-moving
actuator [ 30]).
The safety level PL e (Cat. 4 )/SIL CL 3 is only achieved if
}the safety outputs use 2-channel processing.
NOTICE
Positioning of the safety switch
As the safety switch is not intended for a guard locking device for personal
protection, the safeguard monitored by the safety switch must be positioned
in a way that the access time corresponds at least to the machine's stop-
ping time.
Because of the low operating distance (see Technical details [ 27]) the repetition ac-
curacy of 40 % deviates from the requirement in accordance with EN 60947-5-2 (max.
10%).
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 [ 27]).

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.
INFORMATION
The magnet surface and counterplate may heat up. When installing, make
sure that heat dissipation is guaranteed.
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.
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
DANGER!
Risk to life due to manipulation/defeat of the safeguard
If replacement actuators are obtained, these must be installed as described
in the chapter entitled Installation.
If replacement actuators are used manipulatively or the function of the safe-
guard is defeated, there is a risk to life when operating the plant or machine!
This must be considered in the operator's hazard assessment and the oper-
ator must define appropriate measures to exclude manipulation.
}Do not remove the connector's protective cap until you are just about to connect the
unit. This will prevent potential contamination.

There is a high signal at safety outputs 12 and 22 if the following occur simultaneously:

}There is a high signal at the input S31 (control command for magnetic guard locking)

There is a low signal at safety outputs 12 and 22 if at least one of the following conditions
are met:
}The actuator is outside the response range or
}There is a low signal at the inputs S11 or S21 or
}There is a low signal at the input S31 (control command for magnetic guard locking) or

}The holding force of the locking magnet has not been tested successfully.
Signal output Y32
There is a high signal at the signal output Y32 if the actuator is within the response range
(safety gate closed).
Feasibility monitoring for safety inputs S11 and S21
}If the signal at a safety input switches from high to low, while the other safety input re-
mains high, an unequal status is displayed:
}If the signal at this input switches back from low to high, while a high signal remains at
the other input, a feasibility error is displayed and a partial operation lock is triggered:
The OSSDs are switched off during the partial operation lock.
A switch to a high signal will only lead to normal safety switch operation if both inputs had a
low signal simultaneously. From this moment on, the switch to high signal may occur (par-
tial operation lock see Error display [ 23]).
Magnetic guard locking device and magnet monitoring
}The locking magnet is switched on if there is a high signal at input S31 (control com-
mand for magnetic guard locking) and the actuator is detected (safety gate closed).
}The holding force of the locking magnet is tested on power-up.
}After a signal change at the input S31 to low, wait for at least 500ms, before supplying
a high signal again at the input S31. Also note the max. switching frequency (see Tech-
nical details: System with normal actuator [ 27], System with free-moving
actuator [ 30], under electrical data).
If an open winding or a winding short circuit is detected on a locking magnet that is
switched on, safety outputs 12 and 22 switch to a low state.
}For physical reasons, a remanence (residual magnetism) remains after the locking
magnet is switched off; this is dissipated the first time the sensor and actuator are sep-
arated. Therefore a higher effort is required when opening for the first time.
}If the safety gate is in a locked condition and is opened by force, the safety outputs will
shut down.
