automatically stopped by a pre-set time.
The air compressor starts automatically when the pre-
set restart time comes.

or a backup operation.
● DRYER PRESTARTED (Built-in dryer type)

period until the air compressor can restart in seconds.
● INSTANT STOP / RETRY (Retry is for only Vtype)

air compressor has stopped due to an instantaneous
power interruption (IPI). The RESTART WAIT field
shows an expected waiting period until the air
compressor can restart in seconds.

stopped due to the variable speed drive failure and is
waiting for restart as well. The RESTART WAIT field
