2° Set "Voltage %" trimmer to 83.33% since:
250 (V
V% =
300 (V
having wired terminals 7 - 11.
3° Set "Hysteresis %" trimmer (tripping window) to 10% to
obtain a tripping window between 237.5 and 250 V
(250 V -5% = 237.5 V): the relay will trip at 250 V and regular
operation will start again at 237.5 V.
4° Set the "Delay" trimmer
This makes it possible to delay the relay tripping time (1.... 30
sec). (During the delay the "Power on" LED will flash; at the
end of the delay the "Alarm" LED will turn on and the relay will
trip).
