AUDAX TOP 16 ErP ONLY.
e error currently veried and the last error
(the last error includes the current error) are
conrmed by LEDs D800 to D804 lighting up
on the inverter board.
a) e current error is displayed when all the
SW803 switches are in an OFF position.
b) If only switch 1 of SW803 is lit, the last error
is displayed (the last error includes the current
error)
c) If there is an error, LEDs D800, D801, D802,
D803, and D804 light up.
d) If SW800 is pressed for approximately 1
second, the LED's display status will change,
refer to the table.
e) When SW800 is pressed again, or after 2
minutes, the display goes back to the relative
display 1.
