Set by button
Execute capacity control in accordance with the following
time charts.
(1) ECOMODE (Energy Saving Mode) setting
When you set to ECOMODE by load/unload type con-
trol, if the cycle time for load → unload exceeds 30
seconds, the start pressure setting is automatically
lowered until it reaches recovery pressure + 0.05
MPa to conserve energy.
If 30 seconds is exceeded, the DISPLAY SWITCH /
WIDE MODE light flashes; if 30 seconds is not
exceeded, the DISPLAY SWITCH / WIDE MODE
light lights steadily, and control is executed by pres-
sure setting value of ordinary load/unload type con-
trol.
When using ECOMODE (Energy Conservation
Mode), “ECO” is displayed on the monitor screen.
(
page 14)
(2) Precautions when using ECOMODE (Energy
Saving Mode)
Enabling ECOMODE (Energy Conservation Mode)
requires an air tank that is one turn larger that the air
tank recommended for load/unload type control.
(
For information concerning the air tank, see
page 41.)
This function is used for load/unload type control, and
operates only for the ordinary pressure setting.

Start pressure is automatically reduced to 1 cycle per 30 seconds.
※Start pressure = Cutout pressure
※Recovery pressure = Cutin pressure
According to alteration of the pressure setting value of
section 3.4.1, by setting start pressure 2 (value of F032)
and recovery pressure 2 (value of F033), the control
setting can be easily switched by external button opera-
tion in accordance with usage time on the load side.
During ordinary control, the LOAD light is lit when load-
ing and goes off when unloading. With pressure setting
2, however, the light flashes when loading and goes off
when unloading.
For details, refer to page 24. (The ECOMODE however
cannot be used with pressure setting 2.)
