and accident prevention.
Ensure VDE and local regulations are met, especially those relating to safety.
}Any guarantee is rendered invalid if the housing is opened or unauthorised modifica-
tions are carried out.
}Do not remove the protective cap until you are just about to connect the unit.

Function description
There is a high signal or a low signal at the safety outputs, depending on the position of the
actuator and the state of the inputs. The signal output Y32 signals the position of the actua-
tor.

The outputs cannot be switched back on until there is a low signal at both inputs simultane-
ously.
Safety inputs S11 and S21 are monitored for feasibility. A high signal can be present at the
inputs at offset times; the low signal must be present at both inputs simultaneously (partial
operation lock).

Teaching in the actuator
The first actuator detected by the safety switch PSEN cs4.1 is automatically taught in as
soon as it is brought into the response range.
NOTICE
No other actuator may be taught in once this actuator has been taught.
Installation
}The safety switch and actuator should be installed opposite each other in parallel.
CAUTION!
The unit's properties may be affected if installed in an environment contain-
ing electrically or magnetically conductive material. Please check the oper-
ating distances and the assured release distance.
}Safety switches and actuators should only be secured using M4 screws with a flat head
(e.g. M4 cheese-head or pan head screws).
}The actuator should be protected from unauthorised removal and from contamination.
Close the mounting holes using the seals provided.
}Torque setting: Max. 0.8 Nm.
}The distance between two safety switches must be maintained (see Technical De-
tails [ 20]).
Safety switches and actuators
}Should not be exposed to heavy shock or vibration and
}Should not be used as a limit stop.

PSEN 4.2a/b/p/M12
Operating Manual PSEN 4.2a/b/p/M12

Parallel assembly
Drill holes in the mounting surface (see Di-
mensions [ 19]) and cut threads in the
holes for M4 screws.
Use a screw to fix the safety switch in place.
1. Do not fully tighten the 2nd screw on the
safety switch.
2. Attach the screws for the actuator, leav-
ing a distance of 3 … 6 mm between the
screw head and plate.
Slide the actuator on to the mounting sur-
face. The inscribed area on the actuator
(sensing face) should face the safety switch.
Slide the actuator on to the screws.
Align the safety switch and tighten the
screws.
Align the actuator and tighten the screws.

Orthogonal assembly
Drill holes in the mounting surface (see Di-
mensions [ 19]) and cut threads in the
holes for M4 screws.

Adjustment
}The stated operating distances (see Technical details [ 20]) only apply when the
safety switch and actuator are installed facing each other in parallel. Operating distanc-
es may deviate if other arrangements are used.
}Note the maximum permitted lateral and vertical offset (see Operating distances [ 7]
and Lateral and vertical offset [ 7]).
Operation
Check the function of the safety switch before commissioning.
Status indicators:
}"POWER/Fault" LED lights up green: The unit is ready for operation
}"Safety Gate" LED lights up yellow: Actuator is within the response range
}"Input" LED lights up yellow: There is a high signal at both inputs.
Error display through periodic flashing:
}"Input" LED lights up yellow: the signal switches from high to low at one input, while a
high signal remains on the other input (partial operation).
Remedy: Open both channels of the input circuit.
}"POWER/Fault" LED lights up red: Error message
Flashing codes for fault diagnostics are output to the "Safety Gate" and "Input" LEDs
(see Error display through flashing codes).
Remedy: Rectify fault and interrupt power supply.
Please note the different switch-on delay after UBis applied and after the recovery time of
the sensor and evaluation device.
Error display through flashing codes
The "Safetygate" 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 "Safetygate" 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 4 digits. The
digits are separated by a longer period without flashing. The entire sequence is constantly
repeated.
