1 INTRODUCTION

The nke Heel Angle sensor is a measuring instrument that provides the heel angle

(rolling) of the boat. It can be connected to the nke TOPLINE bus of your installation, or,

thanks to its NMEA 0183 output, to any NMEA receiver that processes XDR frames.

The sensor is supplied with a 5 meter long TOPLINE bus cable.

IMPORTANT

- Read this user guide entirely before starting the installation.

- Any electrical connection on the TOPLINE bus must carried out with the terminal box

90-60-417. Only use TOPLINE bus cable 20-61-001.

- Any intervention on the TOPLINE bus must be carried out with the installation power

switched off.

- For channel settings, please refer to your TOPLINE display guide.

2 LIST OF CHANNELS DISPLAYED

The heel angle sensor, connected to the TOPLINE bus of your installation, creates the

following channels:

Channel Display Unit

Heel (degrees) HEEL  2° Degrees

R_Heel (degrees) (no display) Degrees

The Heel channel is accessible from the displays of the TOPLINE range. The other

channel (R_Heel) corresponds to the fast heel angle of the boat, i.e. to the non filtered value of

the heel. (see channel filtering part).

3 SENSOR CALIBRATION

The heel angle sensor is adjusted at the factory. However, offset setting may be

required to calibrate your sensor on the boat and obtain an absolute value that is optimal.

Follow the calibration procedure below, while visualising the settings on a display : please refer

to the user guide of your display.

OFFSET SETTING

3.1.1 Principle

After the installation, it may be necessary to correct the OFFSET of the heel angle

sensor so that the heel angle displayed is coherent in relation to the heel of the boat.

3.1.2 Setting procedure of the offset (by default the value of the offset is 0) :

This setting will allow to make an angle correction from -180 degrees to +180 degrees.

1. Select the sub-channel offset calib of the Heel channel.

2. Enter the new offset coefficient and confirm. The new setting will be saved to the memory

and will apply to the 2 Topline channels (Heel & R_Heel).

4 DAMPING OF THE CHANNELS

The level of damping of a channel determines the frequency of update of the data

displayed. For example, in rough sea when the boat moves significantly, it is useful to increase

the damping of the heel angle channel to stabilise the value displayed.

Damping is adjustable between 1 and 32, and the default value is 6. The lower this value,

the higher the frequency of update.

Please refer to the user guide of your display to adjust the filter setting.

5 NMEA 0183 OUTPUT

5 times per second, the heel angle sensor transmits the heel angle to its NMEA output

(yellow wire). The measurements of its sensors (accelerometer and rate gyro) are also sent to

its NMEA output, using an nke proprietary frame.

Note that is is possible to independently use the NMEA 0183 output and the Topline bus

link. However, the data transmitted over the NMEA link take into account the existing settings in

the Topline sub-channels (Offset and filtering).

Example of NMEA transmission :

$IIXDR,A,-1.3,D,Heel Angle*0F

$PNKEP,06,-0.988,-0.096,12.0*5D

Connection parameter : 4,800 bauds - 8 bits - 1 stop bit - no parity

IMPORTANT

If you access the filtering parameter from a Performance display (V3.4 or lower), the

label displayed on the LCD screen is incorrect. Indeed, the Performance display indicates

Offset even though the numerical value displayed actually corresponds to the filtering

parameter.

Brief pressing of the ENTER key allows to access the damping sub-channel.

Extended pressing of the ENTER key allows to access the Offset sub-channel.

6 SENSOR DEMONSTRATION SOFTWARE

The demonstration software, downloadable from www.nke.fr, allows to check the good

operation and to set the sensor’s parameters.

The PC must be connected to the Topline bus via the interface TOPLINE PC

reference 90-60-466.

After selecting the type of connection (Topline or NMEA) and the associated port, click on the

“Connect” button to activate the measurement acquisition.

You can now adjust:

 the damping coefficient of the heel measurement,

 the measurement offset,

 the sensor orientation in the boat (front or rear)

8 DIAGNOSTIC OF 1ST LEVEL TROUBLESHOOTING

Before contacting technical support, please check the troubleshooting table below.

Problem Possible causes and solutions

The Topline installation does not detect the Heel Angle sensor. The bus cable is not or is badly connected to the terminal box : check the

plugging and the connection inside the terminal box. Check the state of

the cables : they must not show any sign of wear or cut.

The Topline HEEL channel shows the message FAULT. Cut the power supply of the sensor for a few seconds. If the problem

persists after switching the power back on, contact technical support.

If you do not manage to solve the problem, please contact your distributor.

9 INSTALLATION

Before starting the installation, take the time to select the most appropriate location for

the sensor. It must be installed away from any heat source (solar radiation, cooking plate,

etc…).

Moreover, the sensor must be positioned facing the front or the rear of the boat.

Depending on this positioning, the direction of the sensor must be set as shown on the diagram

below.

CONNECTION TO THE TOPLINE BUS

Connect the bus cable of the sensor inside the terminal box according to the drawing below:

If you reduce the length of the bus cable, strip and galvanise the wires before connecting them inside

the terminal box.
