9.1 Safety circuit
Aicure UJ35 is equipped with a safety circuit, which functions as follows, in case of a malfunction or accident.
1) If the cable between the LED head and the controller is broken, an error signal will be output and an error
screen displayed.
2) If the LED head is short-circuited, an error signal will be output and an error screen displayed.
3) If the LED head temperature becomes excessively high, a warning signal will be output with a warning
screen displayed.
4) If 5 V and GND are shorted by mistake during external terminal connections, the 5 V circuit will stop
operation. When the short circuit is removed, the controller will automatically recover. Note, however, that
if the short-circuited state lasts for an extended period, this product may be damaged.
