The Machine Beeps Continuiously

The Machine Beeps Continuiously


Problem description:

You can hear a beep continuously that comes from the indicates light, even if the machine is rebooted.


Reasons:

1. Temperature sensing probe is bent


The heat alarm sensor board is installed in the middle under the X-axis rail. 



Check it clearly, you can see a black probe on the board.

In order to avoid the needless alarms caused by the short circuit on sensor pin, we installed a heat-shrink tube on the pin (see below pic). If your smart board has installed it, there will be no short circuit. Maybe the smart board is broken. 



Solution:

If the black probe is bent, please make it's straight.



2. The smart board with temp sensor or TL-Timer board is faulty

If the red light of smart board is on and the probe is straight. Maybe the smart board or TL-Timer board  is faulty.


Solution:

Unplug IN2 (If applicable, only on newer Nova  51 and Nova 63) and  IN6 connectors of TL-Timer board, if the beep stops, the problem is smart Heat Sensor board. If not, the problem is TL-Timer board. Please contact us:support@thunderlaserusa.com
