5. Operations
2. Routine Operation
Opening the front cover, check whether the
compressor has any impurities or oil leakage.
Then, open the electrical box door and visually
inspect the tightness of power cable(black).
Since the power cable is loosely connected,
discoloring the red/white/blue color tubes,
turn it off and re-check the cable.
Operation
Press [START] button to start it.
During operation, check the oil level. If
insufficient, stop the operation and replenish the
oil.
Stop
If pressing [STOP] button, it stops
after 10 second no-load operation.
If pressing it again when it stops by
[STOP] button, it immediately stops.
If the P2 pressure is not formed 2.0 bar and
higher in 10 minutes of the operation, it
generates [P-SENSOR TROUBLE] and stops, so
check the inhalation valve opening, slightly
close P2 side ball valve and operate it.
If the P2 side pressure is completely discharge to
the air during the operation, the pressure is ‘0’ bar,
so at the moment, [P-SENSOR TROUBLE] message
is displayed.
When it stops for a long time, close the
discharge side ball valve to prevent any reverse
flow. In addition, press Emergency Stop button
or turn off the main power, avoiding any safety
accident.
When changing the operation conditions such
as operation pressure, refer to page 49.
The initial values of operation pressure are as
follows.
<Compressor’s pressure spec.: 7.0bar>
When the above pressure is set,
It operates under no-load if it is higher than 7.0bar
or under load if it is 6.0 bar and lower(AR03 -
AR02).
When changing operation pressure, other
operation data will be automatically changed for
the optimal operation.
<NOTE>
How to reset: press [STOP] button.
If any trouble occurs during operation, it immediately
stops. Then, check trouble causes, take a corrective
measure and press [STOP] button to release the trouble.
