RUDDER INDICATOR Give
you the position of
the rudder until
2*110". The panel
window
light, power Led, alarm led, backboard and starboard Led's are all
adjustable
with the dimmer from zero to maximum. The panel is made of strong
laminate
(black), the layout is engraved (no paint) and the window is synthetic
(not breakable like glass). The sensor can be just a common
potentiometer
(1kOhm) but a very long life one is included. Panel 12x12cm - 4.7x4.7
inch.
12 / 24Vdc.
The arrow (needle) of the rudder indicator is not part of a fragile galvanometer like in common indicator but monted on a miniature dc servo motor. The instrument can be installed and works in any position and the arrow can show up to 110 degres on both side. The interne light can be dimmed from zero to maximum and the window is made of strong acrylic.
Before installation choose the right place in the dashboard of the
while
house in order to get a optimum view of the rudder indicator while
steering.
Install the 3 ways electric cable and connect the 1 K ohms
potentiometer
to it. The opposite end of the wire has to be connected to the point
marked
POT on the back side (see at bottom) of the instrument. Take care of
the middle
connection
of the potentiometer which, needs as well to be connected to the middle
connection of the point POT.
The ratio rudder-potentiometer can be approximately one (1). This means that both of them will mechanically follow the same angle. However, the gain adjustement (G) on the back side of the instrument makes it possible to tune the indicated angle. So even with a small ruder course, a big indicator angle can be read. The potentiometer should never have to sustain mechanical forces perpendicular to his axes or it will be mounted in line with the rudder shaft or with help of two pulleys with cranted belt. This way it can work for many years. A flexible junction of potentiomenter/shaft is also a good solution.
Watch that the shaft (axe) of the potentiometer never goes to the mecanic end of his course, otherwise it will block and maybe break. The needed course is only 220 degrees (110 Port / 110 starboard). To adjust the instrument on the zero position (middle) first block the rudder in his middle position and turn slowly the potentiometer until the arrow (needel) show the zero position. After this the potentiometer nut must be secured.
The ALARM FUNCTION of the instrument
gives a
few possible failures with buzzer and the lowest left front red led.
- A possible failure in rudder potentiometer or wiring of it:
The needle goes completely to starboard or port or only stays at
position
zero. In this case any action of the steering wheel has no effect on
the
upper green and red LED's.
- Rudder potentiometer out of the middle position or worn out:
The arrow of the instrument goes only to one of the maximum (starboard
or port) which gives an alarm sound and never goes anymore to the
opposite
side.
- intern failure of the instrument when:
Any action on the steering wheel lights on the upper starboard or port
LED's or both of them. Another intern failure is also occurring with a
permanent alarm sound.
The light of the instrument is tuned on the way that with the
dimmer
on minimum position none of the upper LED's lights on. This is to
prevent
uncomfortable reading of the instrument by night navigation. Remark as
well that by no hazard the needle only moves with a significant motion
of the rudder itself, this of course to extend the life of the
instrument. Back to the

INDICATEUR DE
BARRE: Avec
alarme modéle 2019 photos en bas
Vous donne la position exacte de la barre jusqu'à
2x110°.
Le cadran, protégé par un verre synthétique
incassable
est éclairé de l'intérieur. De plus l'aiguille
n'est
pas supportée par un galvanomètre fragile classique mais
par l'axe robuste d'un servomoteur miniature.
L'appareil comprend 2 indicateurs led, bâbord et tribord, et
un contrôle de tension. Tous les voyants lumineux et
l'éclairage
du cadran sont réglables par le gradateur.
Le senseur potentiométrique de 1kOhm, inclus, se connecte par un câble à trois conducteurs à l'arrièrre de l'instrument. Encastrable et mesurant 12x12cm (trou de 10x10cm), cet indicateur de barre peut s'alimenter par les batteries de bord 12 ou 24 volt.
Cet instrument est équipé d'une fonction alarme
sonore
et lumineuse qui peut indiquer une possible malfonction:
- Malfonctions du potentiomètre de barre de 1 KOhm ou
potentiomètre
décentré.
- Potentiomètre de barre défectueux ou fil le reliant
à l'instrument déconnecté.
- Malfonction interne de l'instrument.

ROERSTANDAANWIJZER:
met
alarm (nieuwe 2019 model onder)
Geeft de exacte positie van het roer aan tot 2x110°. De verlichte
aanwijzer, stuurboord, bakboord en voeding-indicatoren zijn alle te
regelen
door de dimmer.
Dit toestel werkt met een 1 kOhm , bijgeleverde potentiometrische
sensor
(drie draden).
Het geheel is in kunststof uitgevoerd (geen glas). Het toestel wordt
gevoed door de accu's en is geschikt voor 12 of 24v boordinstallatie.
Dit toestel heeft meerdere alarm- functies. Zo als b.v. bij defecte
bedrading (los), gebroken potentiometersensor... De naald is niet
gemonteerd
op een gewone fragiele galvanometer maar op de as van een robuuste
microservomotor.
De alarmfunctie van het instrument geeft mogelijke storingen
aan:
- Storing in roer potentiometer of bedrading ervan.
- Potentiometer roer uit het midden of versleten.
- Interne storing van het instrument.
Een alarm wordt te kennen gegeven door een hoge pieptoon en door het
oplichten van het rode onderste linker ledje.
