2° Set "Voltage %" trimmer to 66.7% since:
200 (V
V% =
300 (V
having wired terminals 7 - 11.
3° Set "Hysteresis %" trimmer (tripping window) to 10% to
obtain a tripping window of 200 to 220 V (200 + 10% = 220 V):
the relay will trip at 200 V and regular operation will start again
at 220 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).
