Chapter 19 Alarm threshold of servo loop failure
Set the alarm threshold. of the Servo loop failure for corresponding the rudder angle
① Min. rudder angle for alarm detection of the variation angle (Min.Angle)
② Max. rudder angle for alarm detection of the variation angle (Max. Angle N)
( For normal rudder angle:P/S Max.rudder order from 35 to 45degrees.)
③ Max. rudder angle for alarm detection of the variation angle (Max. Angle W)
(For wide rudder angle: P/S Max. rudder order from70 to 210 degrees)
④ Max. time for alarm detection during one steering gear pump operation(Max.Time SN)
( For normal rudder angle:P/S Max.rudder order from 35 to 45degrees.)
⑤ Max. time for alarm detection during one steering gear pump operation(Max.TimeSW)
(For wide rudder angle: P/S Max. rudder order from70 to 210 degrees)
⑥ Min. time for alarm detection during one steering gear pump operation. (Min. Time S)
⑦ Max. time for alarm detection during parallel steering gear pump operation(Max.Time PN)
( For normal rudder angle:P/S Max.rudder order from 35 to 45degrees.)
⑧ Max. time for alarm detection during parallel steering gear pump operation(Max.Time PW)
(For wide rudder angle: P/S Max. rudder order from70 to 210 degrees)
⑨ Min. time for alarm detection during parallel steering gear pump operation. (Min. TimeＰ)
