⑶ ECOMODE Operation
⑴ Stop Delay Time-Requires 15 seconds
of motor operation to sufficiently cool
down the motor.
If the third stop is done after 70
minutes or more has passed after
the first stop, the motor continues
to operate for 20 minutes after
restart of the air compressor, and
then return to the initial cycle.
⑵
Stop Delay Time – The air compressor
is continually calculating a load ratio.
If the load ratio is 30% and the motor
has stopped/restarted maximum 3
times for the past 90 minutes, then
the motor stops.
⑶
Stop Delay Time – Requires 10 seconds
to completely exhaust internal
compressed air and prepare to restart.
(Note)
ECOMODE setting
Target pressure: 90 psi (0.62 MPa)
Toad/unload cycling interval: 30 sec
The pressure with asterisk may vary
depending on the air receiver’s capacity
and the amount of air consumption.
