12.2 Troubleshooting 

Before contacting your dealer or Logic Rail Technologies for technical 
support please read the following common “problems” and solutions.  
 
1.

 

When the LNFC powers-up it emits three beeps instead of two. 

This indicates that the contents of the non-volatile storage device on 
the module are invalid. Please contact Logic Rail Technologies 
directly for assistance. 

2.

 

The initial/default time broadcast from the LNFC doesn’t appear 
on the DT100/DT300/DT400. 

This could indicate that the LNFC isn’t 

configured as the Clock Master. Check the Option Switch setting. It 
could also indicate a bad connection somewhere on the LocoNet.

 

3.

 

The LNFC displays “LnEr”. 

This indicates that the LNFC 

encountered an error when trying to transmit a message on LocoNet. 
Press the 

SEL

 key to clear the display. If the problem persists please 

contact Logic Rail Technologies directly for assistance.

 

4.

 

The LNFC emits eight long beeps. 

This indicates that there was a 

failure in an attempt to update a value in the non-volatile storage 
device on the module. Please contact Logic Rail Technologies directly 
for assistance.
