Digikeijs DR4088LN flashing red light

[model-trains]

I am building a new layout using Digikeijs DR5000 DigiCentral and DR4088LN's for the feedbacks.

 

There are 4 @ DR4088LN in place, programmed 1 -16,  17-16, 33-16 and 49-16

 

The first 3 have the usual green flashing light, the last one has both a green flashing light and between the Loco net sockets and the S88N socket there is a red fast flashing light? There is nothing plugged in any of the S88N sockets so I am wondering why this one DR4088LN has the flashing light?  

 

Have I an error?

 

Thank you in advance for your help

Just means that the DR4088LN is doing something, is actually working therefore there is a loco on one of the feedbacks connected to that DR4088LN

 

See page 5 of the manual

Brilliant Iain.

 

Having had so many issues to date, I am just trying to make sure every possible situation has been considered.
