USd • Under voltage threshold R/W 50..90 (% of ULn) 70%<br />
Trips the soft starter when the voltage drops below the set level for a time longer than under voltage time delay<br />
(USt).<br />
Line voltage (V)<br />
Note:<br />
Becomes operational only after start signal. When voltage drops to zero (voltage outage), the soft starter will trip<br />
immediately, overriding the delay. Trip message is USF.<br />
USt • Under voltage time delay R/W 1..10 5 s<br />
Adjusts the time of under voltage threshold USd.<br />
