① This function is available for IPI between 20 ms and
the set value (F003: 1 to 5 sec).

AUTO light blinks and the START light turns ON
(growing) to inform that the air compressor is waiting
for restarting from IPI.
④ The air compressor restarts 15 seconds after power
recovers.

(1) IPI means that the power voltage drops to zero (0)
instantaneously.
(2) For the IPI time of less than 20 ms, the air compressor
continues to run.
(3) For the IPI time of more than the setting, the air
compressor judges it as a power failure; the air
compressor stops but does not restart automatically.
Press the START button to restart the air compressor.
