Safety
Intended use
Safety function of safety switch:
}2 safety outputs, each of which supply a high signal when the actuator is in the safety
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 [ 23], System with free-moving
actuator [ 27])
}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 [ 23], System with free-moving
actuator [ 27]).
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 [ 23]) 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

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 input S31 (control command for magnetic guard locking)
and
}The holding force of the locking magnet has been tested successfully.

PSEN sl-0.5n 1.1
Operating Manual PSEN sl-0.5n 1.1
22173-EN-05 10
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 input S31 (control command for magnetic guard locking) or
}The holding force of the locking magnet has not been tested successfully.
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 [ 23], System with free-moving
actuator [ 27], 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 actuator [ 23], System with free-moving
actuator [ 27]).
}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.
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 [ 23], System with free-mov-
ing actuator [ 27]), the locking magnet is no longer activated reliably. The "Lock" LED
registers an error when guard locking.
Possible remedies:
}Set the supply voltage constantly to the upper tolerance range (see Technical details:
System with normal actuator [ 23], System with free-moving actuator [ 27]).
}Select a higher conductor cross section
}Reduce load at the outputs, e.g. with evaluation device PNOZe1.1p

taken place.
This behaviour occurs, for example, when the safety gate is open or the actuator is not
within the response range or the holding force is too low.
Remedy: Rectify the cause (e.g. close safety gate), supply a low signal at input S31
and then supply a high signal again after at least 500ms.
}"Input" LED lights up yellow: Internal error, change unit.
Please note the different times for
}The switch-on delay after UB is applied.
Error display through flashing codes
The "Safety Gate" and "Input" LEDs send flash signals; an error code can be established
from the number and sequence. The "Power/Fault" LED illuminates red.
Each error code is indicated by three short flashes of the "Input" or "Safety Gate" LED.
After a longer pause, the LED will then flash at one second intervals. The number of LED
flashes corresponds to a digit in the error code. The error code can consist of up to 3 digits.
The digits are separated by a longer period without flashing. The entire sequence is con-
stantly repeated.
