Using the documentation This document is intended for instruction.
PSEN cs4.1a/b INFORMATION This gives advice on applications and provides information on special fea- tures. Safety Intended use The safety functions of the safety switch are: Safe shutdown of safety outputs when the actuator is removed beyond the assured re- lease distance s or when the actuator is not detected Remain shut down safely after the actuator has been removed...
PSEN cs4.1a/b Safety regulations Safety assessment Before using a device, a safety assessment in accordance with the Machinery Directive is required. The product as an individual component fulfils the functional safety requirements in accord- ance with EN ISO 13849 and EN IEC 62061. However, this does not guarantee the func- tional safety of the overall plant/machine.
PSEN cs4.1a/b 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.
PSEN cs4.1a/b Unit features Transponder technology for presence detection Pilz coding type: fully coded Dual-channel operation 2 safety inputs for series connection of multiple safety switches 2 safety outputs Safety Device Diagnostics (SDD) – Safety Device Diagnostics can be used to retrieve sensor information on one or more sensors, to perform actions and to read and write configuration parameters.
PSEN cs4.1a/b Function description Basic function 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 the safety outputs are in the OFF state. Electrical states of the inputs and outputs (when safety switch is ready for operation: Power/Fault LED is green): Actuator...
PSEN cs4.1a/b Block diagram A1 A2 S11 S21 SDD Input Power Input Receiver Actuator SDD Output 12 22 Safety Device Diagnostics Safety Device Diagnostics is an option that can be selected independently of the safety-re- lated wiring. When using the Safety Device Diagnostics, up to 16 sensors connected in series can be connected as a subscriber to a fieldbus module.
PSEN cs4.1a/b This prevents wiring errors and an expansion or reduction of the sensors is possible without the need to change existing wiring. – Wiring in accordance with IP20: Rapid installation in the control cabined is enabled. – Wiring in accordance with IP67: Various passive junctions can be used (see Order references for accessories [ 41]) to connect several sensors with only one cable...

PSEN cs4.1a/b Series connection The safety sensors PSENcode are also suitable for series connection with other sensors. Maximum number of PSENcode sensors switched in series connections for SIL CL 3 using PSENcode compact design (PSEN cs3 – cs4, 8-pin): 12 When using other SDD-compatible sensors, the number must be recalculated. In practice, the maximum possible number will be limited by the following parameters, among others: The required SIL level (e.g.

PSEN cs4.1a/b Function test when safety channels are connected in series Before commissioning and after each change, check that the safety function is guaranteed when the gates are opened. To do this, open each gate individually and check the status at the inputs on the evaluation device: Close all the gates.
PSEN cs4.1a/b Connection to Pilz evaluation devices The safety switch PSEN cs4.1a/b can be connected to Pilz evaluation devices, for example. Suitable Pilz evaluation devices are, for example: PNOZelog for safety gate monitoring PNOZpower for safety gate monitoring PNOZsigma for safety gate monitoring...

PSEN cs4.1a/b Installation General CAUTION! Potential loss of safety function due to changed device properties The unit's properties may be affected if installed in an environment contain- ing electrically or magnetically conductive material. – Please check the operating distances and the assured release dis- tance.
PSEN cs4.1a/b Actuator cs2.1 or cs4.1 Procedure actuator PSEN cs4.1: 1. Only use M4 screws with a flat head (e.g. M4 cheese-head or pan head screws). Provide the mounting surface with two drill holes for the actuator screw connection (see Dimensions [ 31]).
PSEN cs4.1a/b Procedure actuator PSEN cs2.1: 1. Use permanently secured M5 safety screws with a flat head (e.g. M5 cheese-head or pan head screws). Provide the mounting surface with two drill holes for the actuator screw connection (see Dimensions [ 31]).
