2° Set "Current %" trimmer to 60% since:
I% =
10 (I
having wired terminals 7 - 12.
3° Set "Hysteresis %" trimmer (tripping window) to 10% to
obtain a tripping window of 6 to 6.6 A (6 A + 10% = 6.6 A):
the relay will trip at 6 A and regular operation will start again
at 6.6 A.
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).
