I have an MC2 controller where the troubleshooting LED is staying on and not blinking. Is there a reset sequence for this?

Is it only the led that is turned on all the time but otherwise the MC2 functions normally?

Not sure what could cause the led to be on all the time.

Was it like that from start or did the unit get like that during operation or after you downloaded?

If you can not communicate with the module and/or it is not working you could try starting the module in safe mode.

You do that by placing a jumper between address high and address low pins.

This will start the MC2 without loading any application.

If it start OK in safe mode try downloading an application to it again.

The unit was manufactured in 2015 but was only installed recently. I will try it in safe mode and see what happens. Thanks for your assistance.
