3. HOW TO OPERATE [Air Compressor Instrumentation]
Buttons/Lights
for Control
Buttons/Lights for
Shutdown and
Alarm Indication
(1) If you want to permanently enable a
remote operation with the REMOTE
light on (non-flashing), place the DIP
switch SW1 No. 4 in an on position. If
you want to use an external setting
switch for enabling/disabling a remote
operation with the REMOTE light on
(flashing), connect the wires between
the external setting switch and the
starter/control box. For more informa-
tion, see page 13.
(2) Before shipping the models with a
built-in air dryer, Hitachi presets its op-
eration mode to automatic. If you want
to enable manual operation mode,
change the settings of the DIP switch
SW2 No. 1 & 2. For more information,
see page 14.
Before disconnecting the power from
the A under manual opera-
tion mode, press the DRYER button
to manually stop the built-in air dryer.
If you disconnect the power before
manually stopping the built-in air dryer,
it restarts as soon as you reconnect
the power, that is, you cannot manu-
ally prestart it before starting the air
compressor.
(3) The LOAD light becomes on (flashing)
when the A is loading under
the alternative I type capacity control.
For more information, see page 32.
(1) The digital monitor displays a dis-
charge air temperature, instead of
the alarm/shutdown code, when
the alarm/shutdown light be-
comes on (flashing) due to high
or abnormally high discharge air
temperature.
(2) At the same time the DRYER light
becomes on (flashing) when the
built-in air dryer causes an alarm/
shutdown problem (
☞
p.
25).
IMPORTANT
IMPORTANT
Remote and local operation means starting
and stopping the A respectively:
with external control signals from other than
the built-in starter/control box and
with the START and STOP buttons on the
built-in instrument panel.
