LED displays
normal
LED state designation
1 (red) o󰀨 primary overcurrent shut down
2 (green) on drive level of low-side is ok
4 (green) on bus voltage max is ok
5 (green) on drive level of high-side is ok
6 (green) on bus voltage min is ok
malfunction
LED state reason
1 (red) on primary current is too high, power unit has been switched o󰀨
2 (green) never on no drive level low-side
4 (green) o󰀨 bus voltage is too high (e.g. mains overvoltage)
5 (green) never on no drive level high-side
6 (green) o󰀨 bus voltage is too low (e.g. mains voltage too low)
