Safety door handle system ICS...-B30 with individually coded safety sensor

The application for thesafety door handlesystem with individuallycoded safety sensor,model ICS, is themonitoring of hingedguard devices. Theseshould ensure that workon and with the machineor system can only becarried out when theguard device is closed.

Safety ensured – but escape route remains openThe barrier fencing ofworking areas providessafety by keeping theoperating personnel awayfrom potentially hazardousmachine movements. Butthere are also cases inwhich fencing can giverise to panic instead ofsafety: when persons,e.g. installation personnel,

are located within thehazard area and the guarddoor is unintentionallyclosed by someone else.For these cases,Schmersal has developeda simple, but effectivesolution - the actuator withan "emergency handle".

This expressionappropriately describesthe escape route functionof the actuator.

ApplicationThe safety door-handlesystem is especiallysuitable for hinged guarddevices. The guarddevice can be openedand closed from outsidevia a rotating movementof the door handle. Theactuating handle latchesin the closed position.

Escape route functionThe ICS-B30 actuator canbe supplied with anemergency handle foropening the guard device.The guard device can beopened from within thehazard area by operatingthe emergency handle. Itis not possible to closethe guard device frominside. The ICS-B30actuator can be suppliedwith a SZ 415 lockout tagagainst unintentionalclosure of the guarddevice, e.g. duringinstallation work onsystems where visibility isrestricted. Mountingplates are supplied forsimple fitting to fencing.

Principle of operationThe ICS safety sensoroperates according to theidentification principle inconjunction with its in-dividually coded ICS-B30actuator. In the insertedposition the ICS-B30actuator latches and theenabling signal to thesafety circuit only occursin this position. Theevaluation of the safetycode in the safety sensortakes place on twochannels. Both channelsprovide mutual monitoringof each other. Each chan-nel has an output withtwo output transistors.

Through this monitoringof the outputs, a connec-tion between the outputand the supply isdetected and switch-on isprevented. A groundconnection and a lowvoltage on an output leadto both outputs switchingoff. The evaluation device istypically a safety PLC or

a safety door monitor.This device usuallyprovides the voltagesupply for the safetysensor and its twooutputs. The supply forthe outputs can includeclock signals for checkingthe connection leads forbreakage and short circuit.

FunctionThe enabling signal to thesafety circuit is onlyissued when the ICS-B30actuator is located withinthe safety sensor and islatched. The two greenindicators (CH1 + CH2)on the ICS safety sensorthen light. The hysteresisrange can be discernedby the flickering of thered indicator (ERR) withthe green indicatorscontinuing to light (theoutputs in this caseremain switched on andexhibit typical hysteresisbehaviour). After thishysteresis range is left,the two green indicatorsgo out and the redindicator lights.

This block diagram shows the basic configuration of the ICS with its two-channel structure.
