Hello there:
There is a power monitoring module inside the controller; according to the theory, when the voltage is less than 24V, the system will enter the power-off protection program, accompanied by a buzzer; you may have different characteristics of the power monitoring chip inside the system; The supply voltage can only meet the conditions.
Approach:
1: Contact the supplier for replacement;
2: Try to increase the power supply voltage to 28V!
