Adjustment Of Rudder Angle Indicator Amplifier (If Kongsberg Delivery) - Kongsberg Frydenbo IRV-2 Maintenance Manual

Maintenance Manual
1. Check that the Steering Gear is in zero position according to the mechanical rudder angle
indicator on the actuator.
2. If the rudder indicators are out of zero position, a zero adjustment can be done on the rudder
indicator amplifier adjuster P20 [2] (+/- 2 degrees).
3. Operate the Steering Gear manually from the Steering Gear room until the mechanical rudder
indicator reaches 35° port.
4. If required, adjust the gain (P30) [3] on the rudder indicator amplifier until the one of the
rudder indicators show 35° port. Additional rudder indicators can be adjusted separately if
necessary.
Independent adjustments can be made on each rudder indicator by means of integrated gain
controls on each indicator.
5. If required, adjust the galvanic isolated +/- 10V rudder position signals as follows:
•
Position the Steering Gear 5° before the Steering Gear mechanical stop.
•
Adjust the P40 [4] until the rudder position signal equals 9V.
