PSEN cs4.1p/M12 Introduction Validity of documentation This documentation is valid for the product PSEN cs4.1p/M12. It is valid until new documentation is published. This operating manual explains the function and operation, describes the installation and provides guidelines on how to connect the product. Using the documentation This document is intended for instruction. Only install and commission the product if you have read and understood this document.
PSEN cs4.1p/M12 INFORMATION This gives advice on applications and provides information on special features. 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 and when there is a high signal at the safety inputs. The safety switch meets the requirements in accordance with: } EN 60947-5-3 with the actuator PSEN cs4.1 : PDDB } EN 62061: SIL CL 3 } EN ISO 13849-1: PL eCat.
PSEN cs4.1p/M12 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.
PSEN cs4.1p/M12 For your safety WARNING! Loss of safety function due to manipulation of the interlocking device Manipulation of the interlocking device may lead to serious injury and death. – You should prevent any possibility of the interlocking device being manipulated through the use of a spare actuator. – Keep the spare actuator in a safe place and protect it from unauthorised access. – If spare actuators are used, these must be installed as described in Installation [ 16].
PSEN cs4.1p/M12 Function description The safety outputs may have a high or low signal, depending on the position of the actuator and the signal status of the inputs. In a safe condition there is a low signal at the safety outputs.

PSEN cs4.1p/M12 CAUTION! Extension of delay-on de-energisation When several (n) devices are connected in series, the delay-on de-energisation time adds with the number of interconnected safety switches. The may. delay-on de-energisation is composed of max. delay-on de-energisation actuator + (n-1) x max.

PSEN cs4.1p/M12 Installation CAUTION! The unit's properties may be affected if installed in an environment containing electrically or magnetically conductive material. Please check the operating distances and the assured release distance. } The safety switch and actuator should be installed opposite each other in parallel. } Safety switches and actuators should only be secured using M4 screws with a flat head (e.g. M4 cheese-head or pan head screws).
PSEN cs4.1p/M12 Slide the actuator on to the screws. Align the safety switch and tighten the screws. Align the actuator and tighten the screws. [4] [3] [2] [1] For the next steps you will need the seals as illustrated.
PSEN cs4.1p/M12 Use the seals (3) to close the mounting holes on the sensing face of the safety switch. Orthogonal assembly Drill holes (for M4 screws) in the mounting surface to secure the actuator and sensor (see Dimensions [ 21]). 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, leaving a distance of 3 … 6 mm between the screw head and plate.
PSEN cs4.1p/M12 Align the actuator and tighten the screws. Use the seals to close the screws' mounting holes on the actuator } (4): Without UL approval } (1): For UL approval Use the seals (3) to close the mounting holes on the sensing face of the safety switch. Adjustment } The stated operating distances (see Technical details [ 22]) only apply when the safety switch and actuator are installed facing each other in parallel. Operating distances may deviate if other arrangements are used.
PSEN cs4.1p/M12 } "Power/Fault" LED lights up red: Error message Flashing codes for fault diagnostics are output to the "Safety Gate" or "Input" LED (see Error display through flashing codes). Remedy: Rectify fault and interrupt power supply. Please note the different times for } The switch-on delay after UB is applied } The recovery time of the sensor and evaluation device.
