3 Zelio Time - iming relays Funcions and selecion Funcions Diagram Operaing principle On-delay Conrol or supply conac Timing sars when he relay is energised. When he se ime delay () has elapsed, he oupu conac closes. When he relay is de-energised, he conac reurns o is iniial posiion. The oupu conac does no close if he duraion of he conrol insrucion is less han he se ime delay. Timing can also be sared by opening of a conrol conac (models wih exernal conrol). Off-delay Conrol or supply conac Energisaion of he relay or closing of he conrol conac (models wih exernal conrol) causes he oupu relay o close insananeously. Timing sars when he relay is de-energised or when he conrol conac opens. When he se ime delay () has elapsed, he conac reurns o is iniial posiion. If he energisaion ime or closing ime of he conrol conac is less han he minimum ime specified, he iming period does no sar. On and Off-delay Conrol or supply conac a r This funcion is a combinaion of he On and Off delay funcions. The iming cycle mus be conrolled by an exernal conac. Symmerical The On and Off delays are equal. Asymmerical The On and Off delays are adjused by differen poeniomeers. Timing relay wih pulse on energisaion conac Energisaion of he relay causes he oupu conac o close insananeously and sar he iming period. The conac reurns o is iniial posiion when he se ime delay () has elapsed or if he supply is cu off before he end of he iming period. Timing relay wih pulse on de-energisaion or on opening of a exernal conrol conac Conrol or supply conac De-energisaion of he relay or opening of he exernal conrol conac (depending on model) causes he oupu conac o close insananeously and sar he iming period. When he se ime delay () has elapsed, he conac reurns o is iniial posiion. Flashing relay conac a r Energisaion of he relay sars he flashing period and causes he oupu relay o sar he flashing cycle. When he relay is de-energised, he conac reurns o is iniial posiion. Symmerical flashing relay The On and Off flashing phases are idenical. Asymmerical flashing relay The On and Off flashing phases are adjused by differen poeniomeers (a and r). Time delay relays for sar-dela sarers Sar Dela Energisaion of he relay causes he sar conacor o close insananeously and sars he iming period. When he se ime delay () has elapsed, he sar conacor reurns o is iniial posiion and he dela conacor closes, afer a breaking ime sufficien for he changeover.

4 Addiional funcions Exernal conrol of saring: opening of an exernal conac conneced o he relay sars he iming period. Closing of his conac reses he imer. Exernal conrol of parial sop of ime delay: closing of an exernal conac conneced o he relay allows he iming period o be inerruped. The ime elapsed is memorised. Timing resars as soon as he conac opens. This ype of conrol enables he oalising funcion o be performed. Exernal adjusmen of he ime delay: one or more exernal poeniomeers can be used for remoe adjusmen of he iming period or periods.
