AUTO IDLE control (Purge control)
This model is equipped with auto idle control operation mode. This operation mode is recommendable
for such use: not so much air consumption is required and it is used continuously and also power
consumption under unloaded operation is required to be saved. Use this mode, depending upon the
need and demand. For the selection of this mode, switch on “AUTO IDLE” on the operation panel.
Select this operation mode freely, according to required air consumption.
<Procedure>
①
During operation, push on the switch
“
1
”
“AUTO
IDLE”.
②
Then the indicator lamp “AUTO IDLE” “2” goes on.
③
In order to stop this operation mode, push again
“AUTO IDLE” switch “1” and then the lamp “2” goes
out to disengage this purge mode.
[Function of AUTO IDLE control]
Function
Conditions of AUTO IDLE lamp
When purge timer functions
①
When air consumption decreases, engine speed drops to the
minimum with the function of pressure regulator and
speed regulator. And when it decreases further, the
unloader valve closes gradually to raise intake negative
pressure. Negative pressure sensor (PRS1) detects this
rising negative pressure. Then when the intake negative
pressure becomes higher than the set pressure, purge
operation timer functions to make “AUTO IDLE” lamp
flicker in short intervals.
Lamp flickers at short
intervals.
Purge operation
②
When this condition continues for a certain time, the
purge/starting unloader solenoid valve (SV1) for purge
mode functions to start purge mode operation.
Consequently, the pressure inside separator receiver tank
drops and reduces the power of compressor air end. In this
stage, the lamp “AUTO IDLE” flickers at longer intervals.
Lamp flickers at longer
intervals.
At load operation under auto idle
control mode
③
When air consumption increases and the pressure used for
consumer side drops below the purge releasing pressure,
purge/starting unloader solenoid valve (SV1) gets “OFF”
and it is transferred to normal operation.
“AUTO IDLE” lamp changes from flickering to lighting on.
Lamp goes on.
