Riverpilot is turned off
Rate of Turn display is turned off
Riverpilot is on "FU/WEG" mode
Spindle wheel of the gyro sensor isn't turning due to a mechanical issue
Less then 100 millivolts
Less then 20 millivolts
Less then 10 millivolts
More then 10 millivolts
The ship on Autopilot does not follow the asked course.
The Rate of Turn display is turned off and the Riverpilot is on "Auto" mode.
The spindle wheel of the gyro is not (yet) at the correct speed.
The Rate of Turn needs adjustment.
The "gain" and "speed" potentiometers are not allowed to adjust without special test-equipment
The "test" potentiometer should be adjusted on board after installing a gyrosensor
The "speed" potentiometer is for the maximum curve of the Riverpilot
To adjust the "zero" of the indicator in case the gyro sensor is not exactly zero
To adjust the "zero" of the indicator, when the indicator is turned off
To adjust the "zero" to the processor of the BasicTriplePilot
To adjust the "test" of the Rate of Turn signal
The "isozero" potentiometer is used for zero adjustment for the Riverpilot
The "zero" adjustment is used for adjusting the "zero" indication on the radar
On board ONLY adjust potentiometers "zero" and "isozero".
Wheelhouse, with a short as possible cable between Rate of Turn (interface) and Gyro sensor, mounted on a solid vibration-free foundation.
Engine room, as high as possible, preferrably above the engine.
Engine room, as high as possible, as close as possible to the longitudinal axis of the ship.
Engine room, as close as possible to the longitudinal axis of the ship, mounted on a solid vibration-free foundation at about waterlevel.
Adjust zero on display AlphaTrioPilot, adjust zero on gyro sensor, adjust zero in processorbox AlphaTrioPilot
Adjust zero on gyro sensor by measuring the 20mV/degree output voltage, adjust the zero on the display of the AlphaTrioPilot, adjust the zero in processorbox AlphaTrioPilot
Adjust zero on display AlphaTrioPilot by turning zero on gyro sensor, adjust zero in processorbox AlphaTrioPilot
Adjust zero in processorbox AlphaTrioPilot, adjust zero on display AlphaTrioPilot, adjust zero in gyro sensor
Any modification made to equipment already approved shall cause the type-approval to be forfeit.
The rate-of-turn indicator shall be located ahead of the helmsman and within their field of vision.
The sensor system shall be installed as far as possible amidships, horizontal and aligned with the ship's fore-and aft-line. The installation site shall as far as possible be free of vibration and be liable only to modest temperature variations. The indicator unit shall if possible be installed directly above the radar display.
If slave indicators are installed, they shall satisfy the requirements which apply to rate-of-turn indicators.
