Rdbnd; Motspd 100; Spool Valve - Vdo Pilot Control Montageanleitung Und Bedienungsanleitung

If there is no speed data available, set this to N N O O T T R R S S P P D D .
The Pilot can use speed data from an NMEA 0183 speed or velocity message, refer to the PILOT BOX
Manual for more details.
Rudder Deadband
Some steering systems have slack in them, owing to wear or system design, which gives a few uncontrol-
led degrees of rudder movement. Hydraulic drive and power steering systems often have some overshoot.
To stop the Pilot trying to correct these small movements which it can never do, the rudder deadband set-
ting allows a small course error movement without the pilot applying rudder.

The range is from 0 (0º) to 20 (2º). Too much slack in the steering system will affect Pilot performance.
Motor Speed control
PWM (Pulse Width Modulation) is a method of controlling the speed of the vessel's steering motor so that
rudder operation is smooth. This is especially useful if the vessel has a high steering inertia.
Motor Speed Control and the Motor Speed Reduction Angle are used to assist PWM, to achieve smooth rud-
der operation.
Motor Speed Control is the amount of power, output from the Drive Unit, needed to move the rudder bet-
ween its limits in a time suitable for the vessel.
The Motor Speed Control setting starts at 100%, which is the maximum rudder speed the selected drive unit
can provide, press the
to Hardover time calculated for your system (Hardover time is double at 50% power).
As a guide, the Hardover to Hardover time should be approximately:
- Planing vessel's
- Semi-Displacement vessel's
- Displacement and Sailing vessel's 15 - 18 seconds

The range is from 100% to 50% in increments of 5%.
Pwm off
PWM is automatically turned off when J3 is set for spool valve operation.
Spool Valve (Solenoid Control)
If the system uses Spool Valve Control for the steering system, the Jumper J3 in the Pilot Computer will need
to be set to "Spool Valve", this automatically sets Motor Speed Control to P P W W M M O O f f f f (see PILOT BOX Manual).
