Problem with Ax 1500 status LED

I was using my AX1500 normally but suddenly it started to stop then i noticed that Status LED is always ON not OFF or blinking. It is always on i switched controller input mode re installed the firmware but Status Led is still on. Does anyone know what does it mean and a way of fixing it?

The LED not flashing could indicate an under voltage condition. That would occur if you have less than 11V at the input. Check with the PC utility in the Run tab the voltage and temperature reading.
