Error Messages/ Removing Errors 

 

If from time to time error message “No Detector Input Data” appears, this can be caused 
by an uncorrected heeling magnet of the compass. 
So please check if at all corrections (deviation adjustment) were done. If not remove or 
position heeling magnet as far as possible to the compass with detector. To find out how to 
do this please refer to the relevant operations manual of the compass or compass 
binnacle. 

 
 
 
 
 
 
 
 
 
 
 
 

 

Error Reason 

Remedy 

”Power Failure“,  
 

Main- /Emergency 
voltage below 18 VDC. 

Make sure power supply : 24 VDC. 

”Transmission Error“,  
 

Transmission error table 
not valid 

Switch off and on instrument. 
Carry out transmission error correction 
procedure (ref. “Compass Reset“). 

”No Detector Input 
Data“,  
 

Detector data not valid 

Make sure correct mounting of detector and 
right distance to compass. 
Make sure correct wiring of detector. 
Make sure that there are no magnetic 
interferences at detector location. 
Check correct function of detector by use of a 
multimeter *). 

No function 

 

Switch on instrument. 
Adjust dimmer to max. brightness to verify that 
power is connected. 
Make sure wiring and right voltage supply.  

No data transmission. 
NETcourse shows no 
error message.  

 

Make sure that data cables and connectors 
are in order. 
Interchange data cable A and B. 
Make sure that correct output data 
specification was selected. 

 

 *) Ref. to chapter „Pin Connection of Plugs/Connectors“ 
Measure resistance between: 
Cosine und Reference: 60 Ohm, Sine und Reference: 60 Ohm,  Sine und Cosine: 120 Ohm  
Exitation 1 und Exitation 2: 50 Ohm, Exitation 1 or Exitation 2 and Reference: not connected 
The values should be found within a tolerance of +/- 20%, else the detector might be defective.

Attention:

  The display shows existing operational errors and gives further 

information. Please follow this information and refer to the error 
shooting chapter of this operations manual. If the error cannot be 
removed in this way switch off the instrument and call the 
manufacturer.  
Please pay attention to each error message carefully, else proper 
operation cannot be guaranteed and safety of the vessel may be 
endangered.
