Environment

• Xenta Programmable Controllers
• Xenta 280, 281, 282, 283, 300, 301, 302, 401, 401:B

Cause

The indicator lights on the face of the Xenta controllers can help explain the state of the controller with different actions. 

Resolution

There are two LED indicators – one red and one green on the Xenta programmable controllers.

The red service diode is primarily an error indication. It also lights up if the Service pin is activated.

1. A solid red light usually indicates that the hardware has failed.  Please see a few simple steps to deactivate the solid red light below.
   • Use a reset dongle to wipe the controller then reinstall the firmware and menta program.
   • If the controller is the group master you might try to assign a different controller to group master.  This method has not been proven but has worked before during internal testing.
     NOTE: The hardware may need to be replaced if the solid red light continues after these steps.
2. If the red indicator light is blinking once per second this will indicate a non-configured node.
   • If the controller has been commissioned you might try to decommission the controller and try again.
3. If the red indicator light is off this would indicate that it has been commissioned and added properly to the network.  You should not see the red indicator light if the controller is working properly.
4. The green status diode blinks once per second to indicate that the program is running properly.
