SafetyOperating Manual PSEN ml b 2.1/2.21003895-EN-08 72 Safety2.1 Intended useThe safety gate system is used for interlocking and guard locking swing gates and slidinggates.The safety gate system can be operated in two ways:}Unlocking with conditionThe safety gate system prevents the safety gate from being unlocked while there is anyhazard within the danger zone.}Unlocking without conditionThe operator can unlock the safety gate system at any time. After starting the unlock-ing, the guard locking creates a stop command. The time required to unlock the inter-locking guard has to be longer than the time required to stop the hazardous machinefunction.The hazardous machine function may only be executed under the following conditions:}There is a high signal at safety outputs 12 and 22 and}There is a low signal at safety outputs S31 (Lock/Unlock Request 1) and S41 (Lock/Un-lock Request 2).Safety inputs S31 and S41 (solenoid operation) may only be operated under the followingcondition:}Plant is in a safe conditionMake sure that this is the case with an AND operation in the safety system immediatelybefore the output is operated.The safety switch meets the requirements in accordance with:}EN 60947-5-3 with the actuator PSEN ml 2.1: PDDB}EN 62061: SIL CL 3}EN ISO 13849-1: PL e (Cat. 4 )}ENISO14119: Coding level High, type 4The safety switch may only be used with the corresponding actuator PSEN ml 2.1.The safety level PL e (Cat. 4 )/SIL CL 3 is only achieved if}the safety outputs use 2-channel processing}The solenoid has 2-channel operation via safe, tested outputs, suitable for PL e (Cat.4)/SIL CL 3 applications.With 1-channel operation of the safety inputs S31 (Lock/Unlock Request 1) and S41 (Lock/Unlock Request 2) it is only possible to achieve safety level PLd(Cat.2)/SILCL2.Foreseeable misuse}Safety switches and actuators of the safety gate system PSEN ml b 2.1/2.2 must notbe used as mechanical limit stops}Use of the PSEN ml b 2.1/2.2 under corrosive environmental conditions (cooling emul-sions, surface treatment, gases, …)Please contact Pilz.
SafetyOperating Manual PSEN ml b 2.1/2.21003895-EN-08 82.2 Safety regulations2.2.1 Safety assessmentBefore using a device it is necessary to perform a safety assessment in accordance withthe Machinery Directive.Functional safety is guaranteed for the product as a single component. However, this doesnot guarantee the functional safety of the overall plant/machine. In order to achieve the re-quired safety level for the overall plant/machine, define the safety requirements for theplant/machine and then define how these must be implemented from a technical and organ-isational standpoint.2.2.2 Additional documents that applyPlease read and take note of the following documents.Only for use of the Safety Device Diagnostics (SDD):}Operating manual for the fieldbus module, for example SDD ES ETH or SDD ESPROFIBUS}System description "Safety Device Diagnostics"For the use of passive junctions:}Operating manual of a passive junction, for example:– PSEN ix2 F4 code– PSEN ix2 F8 code– PDP67 F 4 codeYou will need to be conversant with the information in these documents in order to fully un-derstand this operating manual.2.2.3 Use of qualified personnelThe products may only be assembled, installed, programmed, commissioned, operated,maintained and decommissioned by competent persons.A competent person is a qualified and knowledgeable person who, because of their train-ing, experience and current professional activity, has the specialist knowledge required. Tobe able to inspect, assess and operate devices, systems and machines, the person has tobe informed of the state of the art and the applicable national, European and internationallaws, directives and standards.It is the company’s responsibility only to employ personnel who}Are familiar with the basic regulations concerning health and safety / accident preven-tion,}Have read and understood the information provided in the section entitled Safety}Have a good knowledge of the generic and specialist standards applicable to the spe-cific application.

After activation, the inputs must be low. Another pulse (length350 - 400 ms ) at these inputs deactivates guard locking.4.2.1 Activation with specification of direction}The guard locking is activated when the time between the rising edges from S31 to S41is between 40ms and 500ms (S31 before S41).}The guard locking is deactivated when the time between the rising edges from S31 toS41 is between 40ms and 500ms (S41 before S31).S31S41tmaxGuard lockingS31S41tmaxGuard lockingLegendtmax Maximum time between the rising edges from S31 and S42

As a result, a sensor can be exchanged, e.g.when servicing, without the need for special measures.An exchange can be detected via the fieldbus module e.g. through the serial number.}With Safety Device Diagnostics there are the following diagnostic options for the field-bus module:– Poll information of the sensors (examples: what sensor in the series has switched,at what point could there be an open circuit in the series connection)– Read configuration parameters of the sensor (examples: Number of teach-in pro-cesses remaining, serial number of the switch)– Perform actions (example: poll updated actuator name)– Selectively activate or deactivate guard locking of individual PSEN ml within aseries connectionThe results of the sensor diagnostics can be checked already during the installation phasevia the display in the fieldbus module, without the need to connect the fieldbus module tothe network.}With Safety Device Diagnostics there are the following diagnostic options for the field-bus module for simple wiring:– Information is passed on via the fieldbus module directly to the network– Mappings of the signal outputs to the sensor are automated by the SDD.This prevents wiring errors and an expansion or reduction of the sensors is possiblewithout the need to change existing wiring.– Wiring in accordance with IP20: Rapid installation in the control cabined is enabled.Further information on Safety Device Diagnostics can be found in Additional documentsthat apply [ 8].}Series connection of diagnostics with Safety Device Diagnostics
