8.1 Loop Break Alarm On Amperometric TransformerThis function allows to measure load current and to manage an alarmduring malfunctioning with power in short circuit or always off. Theamperometric transformer connected to terminals 15 and 16 must be50mA (sampling time 80ms).• Set scale end value of the amperometric transformer in Ampereson parameter 47• Set the intervention threshold of the Loop break alarm in Ampereson parameter 48• Set the intervention delay time of the Loop break alarm onparameter 49• You can associate the alarm with a relay by setting the parameter, or as .If a remote control switch or SSR remains closed, the controller signalsthe fault by showingon display 2 (alternatively with acommand setpoint).If instead the power stage remains open, or the load current is lowerthan the value set on , the controller shows ondisplay.You can display the current absorbed during the closure phase of thepower stage.Press Effect Operation1 This key enables to scrollon display 2 the output Press until the writingpercentage, auto/manappears onselection, setpoint anddisplay 1 and display 2alarms.shows the current inamperes ( >0).The value is alsomaintained when nocurrent circulates on theload.ηττπ://νιχοντρολσ.χοm21
