In- and Output Calibration

Input Calibration using Dummy Values

In some installations, it may be required to carry out the output calibra-
tion before the input calibration. E. g., if the RAI system is installed and 
wired up, but the rudder cannot be actuated because the steering gear is 
not operational. As a temporary measure in such cases, the input may 
be calibrated using the feedback potentiometer supply and center tap 
potentials as input signals, instead of the actual feedback signal.

To calibrate the input using dummy values:

1.

Disconnect the feedback unit from the RAC, TB 1.3 through 1.6
(refer to circuit diagram 5014-0115-01).

2. Proceed as if carrying out the initial input calibration (see “Initial 

Calibration” on page 6-16).
However, instead of putting the rudder to the hardover and midships 
positions,

shorten TB 1.4 to 1.5 to connect the negative feedback supply 
potential to the input. Then, enter the nominal hardover port 
angle (e. g. -45 or -70 degrees) in the rudder angle control and 

click 

 to set the hardover port calibration point;

shorten TB 1.4 to 1.6 to connect the feedback center tap potential 
to the input. Then, enter a value of 0.0 degrees in the rudder 

angle control and click 

 to set the midships calibra-

tion point;

shorten TB 1.4 to 1.3 to connect the positive feedback supply 
potential to the input. Then, enter the nominal hardover star-
board angle (e. g. 45 or 70 degrees) in the rudder angle control 

and click 

 to set the hardover starboard calibration 

point.

3. Re-connect the feedback unit to the RAC, TB 1.3 through 1.6.
