If an error occurs when replacing the SD CARD, the POWER LED is lit in red, so insert a writable SD CARD.

5) Operation when an error occurs
If any error occurs while the GLT400 is operating, the POWER LED is lit in red and the buzzer sounds. You
can check the error details from the GLT400 Setting App. Use the same software to clear the error.
For details of the error, refer to "5.3 List of Error Codes".
If the system goes down due to a hardware failure or firmware malfunction, the buzzer will sound
continuously and the POWER LED and START LED flashes in red alternately.
In this case, you cannot get the error log with GLT400 SETTING APP.
If this happens, turn off the power switch and please contact us.
