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], System with normal actuator and stainless steel base
plate [ 34])
}EN 62061: SIL CL 3
}EN ISO 13849-1: PL e and Cat. 4
}EN ISO 14119: Coding level Low, 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], System with normal actuator and stainless steel base
plate [ 34]).
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

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:
}The actuator is within the response range (safety gate closed) and
}There is a high signal at the inputs S11 and S21 and
}There is a high signal at the input S31 (control command for magnetic guard locking)
and
}The holding force of the locking magnet has been tested successfully.
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:

PSEN sl-1.0p 1.1/1.1 VA
Operating Manual PSEN sl-1.0p 1.1/1.1 VA
1003821-EN-12 11
}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 [ 24]).
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], System with normal actuator and stainless steel base
plate [ 34], 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.
Lateral and vertical offset
}Max. vertical offset 5 mm

}Max. lateral offset: 3 mm
Wiring
Please note:
}You must comply with the specifications stated in the technical details (see Technical
details: System with normal acutator [ 27], System with free-moving
actuator [ 30], System with normal actuator and stainless steel base
plate [ 34]).
}The power supply must meet the regulations for extra low voltages with protective sep-
aration (SELV, PELV).
}The inputs and outputs of the safety switch must have a protective separation to
voltages over 60 VDC.
INFORMATION
Only use safety relays with a 24 VDC supply voltage. Safety relays with a
wide-range power supply or in AC device versions have internal potential
isolation and are not suitable as evaluation devices.
}Ensure the wiring and EMC requirements of EN 60204-1 are met.
}When connecting in series, make sure you comply with the wiring technology require-
ments (DIN EN 60204-1) and manipulation protection requirements (EN ISO 14119).
Guidelines for cable length
The max. cable length depends on the voltage drop at the safety switches. The level of
voltage drop is determined by the:
}Cable resistance
}Current of the device and the current load of the outputs
If the level of the supply voltage at the device connector falls below the minimum permitted
value (see Technical details: System with normal actuator [ 27], System with free-mov-
ing actuator [ 30], System with normal actuator and stainless steel base
plate [ 34]), the electromagnet is no longer activated reliably. The "Lock" LED registers
an error when guard locking.

WARNING!
Risk of death and serious injury by reaching into the danger zone!
The actuators enable a warped gate to be closed. A gap may occur on the
gate as a result. Make sure that the gap remains small enough to exclude
the possibility of reaching into the danger zone.
