(r) stays latched until supply voltage has been interrupted. ri cyclic timer pulse started on application of supply voltage the time period starts to run. the relay switches on and off for the periods, beginning with a pulse. the time period for t1 and t2 can be different. the function continues as long as voltage is applied. rp cyclic timer pause started on application of supply voltage the time period starts to run. the relay switches on and off for the periods, beginning with a pause. the time period for t1 and t2 can be different. the function continues as long as voltage is applied. s star delta on application of supply voltage the contact 17 - 18 of the star relay is closed and the star time t1 begins to run. on completion of the t1 the star relay de-energises and the dwell time t2 starts. on completion of t2 the contact 17 - 28 of the delta relay is closed and remains in operation as long as the supply voltage is applied. t true off delay when supply voltage u is engaged the relay energises (contacts 15-18). when the supply voltage is removed the set time t begins to run. on completion of time t the output falls back to the off position (contacts 15-16). if the supply voltage u is re-engaged to the unit before t has elapsed, the time already elapsed is cancelled and starts again next time the supply voltage is interrupted. a u/t r b u/t s r c u/t s r d u/t s r e u/t s r h u/t s r t2 t1 17 - 28 17 - 18 s u/t y memory f u/t r g u/t r ri u/t r rp u/t r t u r www.imopc.com
