10 For exernal indicaion (e.g. visual, elecrical or acousic signal) of a malfuncion, he insallaion of a failure indicaion elemen is recommended. Such an elemen is no necessary o fulfil he safey funcion of he valve. (For furher informaion please see he corresponding daa shee no. 5.4.). suiable air reamen uni (dehydraion, filraion, lubricaion) mus be conneced upsream of pressure por (). Lubricaion can only be omied if he conneced consuming device and all addiional equipmen is suied for oil-free operaion. egree of filraion: 5 µm. The lubricaion should be adjused o supply only enough oil o form a film on he valve spool and bore. Excessive lubricaion may cause a build-up of oil in he pilo lines and cause sluggish operaion of he valves.the size of pressure regulaor, lubricaor and filer mus be consisen wih he inle por size. n accumulaor ank is recommended beween he pressure regulaor and safey valve. The operaing pressure mus no drop below bar and he use of a pressure swich is suggesed. Safey valves mus be insalled as close as possible o he cluch and brake. Cauion: Non conrollable elemens such as quick exhaus valves, nozzles, non reurn valves, ec. mus no be mouned beween safey valve and cluch brake. I is he responsibiliy of he purchaser and/ or insaller of he Norgren-Herion safey valves o make sure ha he valve and all oher componens comply wih all relevan naional regulaions and he specificaions of he local safey associaions. The valves should be checked a inervals depending on he loads o which hey are subjeced, a leas, however, once a year. The relevan ess mus be carried ou according o he corresponding operaion and mainenance insrucions of he uni and he local safey regulaions. In case of malfuncions he uni has o be esed and/or replaced immediaely. epairs and mainenance mus only be carried ou by he afer-sales service of he valve manufacurer or by a qualified engineer rained by he valve manufacurer. Imporan for use a presses: The combinaion wih he elecrical press conrol mus mee he IN-EN-ISO requiremens. If wo separae valves are used o conrol he cluch and brake, please observe daa shee no ll liabiliy is denied for unauhorised modificaion of he unis, insallaion or usage no in accordance wih he manual, he local safey requiremens and he principles of IN-EN-ISO Warning These producs are inended for use in indusrial compressed air only. o no use hese producs where pressures and emperaures can exceed hose lised under Technical feaures. Before using hese producs wih fluids oher han hose specified, for non-indusrial applicaions, life-suppor sysems, or oher applicaions no wihin published specificaions, consul NOGEN. Through misuse, age, or malfuncion, componens used in fluid power sysems can fail in various modes. The sysem designer is warned o consider he failure modes of all componen pars used in fluid power sysems and o provide adequae safeguards o preven personal injury or damage o equipmen in he even of such failure. Sysem designers mus provide a warning o end users in he sysem insrucional manual if proecion agains a failure mode canno be adequaely provided.
