Initial operation: Servo
Steering without Autopilot
Use this paragraph only if you have
no Tecnautic Displays installed:
1. Select set-up mode, function "0":
2. Move rudder manually into middle posi-
tion and rotate rudder angle sensor shaft man-
ually so that the red and green LED appear to
be both at minimum brightness (dim). Now lock
the sensor shaft with its fixation screw.
3. Rudder sense: Move rudder manually to
the left (like for a left turn!) and observe increas-
ing intensity of the left (green) LED. Moving the
rudder right increases the right (red) LED's in-
tensity. If the intensities are reversed, set the
jumper JP1 in the DRIVEBOX to its other state
(e.g. from closed to open).
4. Rudder travel limit: Press the "SERVO"-
button once. The red "AP"-LED should be lit now
and the green "SERVO"-LED should be off.
Move the rudder manually to approx. one de-
gree before the mechanical stop of either side,
then press the "AP"-button briefly. This will place
the present rudder angle into memory and the
drive will not go any further.
Exit the set-up mode with the "OFF"-button.
5. Attention: the rudder will move under
power during the following step! Be
ÿ ÿ ÿ ÿ
ready to press the "OFF"-button imme-
diately if the rudder moves towards ei-
ther end. Rotate Electronic Steering Wheel to
the middle and press the "SERVO"-button
(green SERVO-LED illuminates).
If the rudder follows the movements of the
electronic steering wheel, go to step 6. If the
rudder moves to either end, press the "OFF"-
button immediately and switch off the power to
the DRIVEBOX.
In case of a reversible drive motor or in case
of Servo Valves, reverse the leads at terminals
7 and 8 of the DRIVEBOX; for a continuous run-
ning pump, reverse the leads for the valves at
terminals 2 and 4 of the DRIVEBOX. Then switch
on power and go again to step 5.
6. Verifying the rudder end limit: Press the
"SERVO"-button (green "SERVO"-LED goes
ON) and rotate the electronic steering wheel to
either side. If a mechanical stop can be hit (ei-
ther within the hydraulic cylinder or externally),
enter set-up mode again (step 1) and repeat
step 4, but stay further away from the mechan-
ical stop.
1. Entering the SETUP mode: press and
hold the SERVO and OFF buttons for 10 sec-
onds, until an LED comes on (different proce-
dure for Throttle station).
(leave the SETUP mode with the OFF-but-
ton)
2. Selecting the SETUP function 0..7:
The next function can be selected by briefly
pressing the SERVO-button. The function
number (0 to 7) is "displayed" by means of the
two LEDs in binary code (the AP-LED repre-
sents bit 0, the SERVO-LED is bit 1). SETUP
function 1 is active after entering the setup
mode.
3. Inserting or modifying a setup parame-
ter: press the AP-button briefly and the present-
ly active setup function will accept the new pa-
rameter.
4. Description of SETUP Functions 0 to 7
0: Rudder Angle display by LED brightness.
No entry possible.
1: Enters the actual rudder angle into the
"maximum rudder angle" at the
moment when AP is pressed.
2: Reserved for Throttle Setup
3: Reserved for Throttle Setup
4: Reserved for Throttle Setup
5b: The servo wheel will be locked by pressing
the AP-button in mode 5b (mode
5b is active after mode 4 before
the SERVO-button has been re-
leased. After releasing the SER-
VO-button, locking is not possi-
ble). The red AP-LED flashes fast
as long as the servo wheel is
locked.
6: Illumination group: The illumination group
number of that Servo Wheel can
be altered by pressing the AP-
button. A number from zero to
three is possible. The new num-
ber is indicated by a correspond-
ing number of zero to three short
beeps.
7: Reserved for Throttle Setup
Unlocking a locked Servo Wheel:
Press and hold the SERVO- and the OFF-
button; do not release them and press the AP-
button four times. Then release the SERVO-
and the OFF-button. Flashing of the red AP-
LED stops and the servo wheel is ready for
use.
