 Interlock: N.O. Relay contact – It is closed as soon as the
rotational frequency exceed the threshold defined with window
no.102 (plus histerisys defined by window 105).
 Speed setting: Pump speed setting – linear setting between 1V=15
Hz and 9 V= Win.120 setting:
 High speed (60 Hz): Vin>9 V
 Low speed (40 Hz): Vin<1 V
