SYSTEM OPERATING LAMP
The
system operating lamp indicates that the controller mount-
ed on the machine is turned ON.
System operating lamp lights up in green when the controller is
turned on and goes out in a few minutes after the starting
switch is turned to OFF position.
Before operating the battery disconnect switch, check that sys-
tem operating lamp is not lit.
NOTICE
If the battery disconnect switch is turned to OFF position
(O) while the system operating lamp is lit, the data in the
controller may be lost.
If the data are lost, when you try to start the engine next
time, “L04” is displayed on the machine monitor and the
engine may not start.
If the engine cannot be started, ask your Komatsu distribu-
tor for inspection and repair.
REMARK
• Even if the starting switch is in OFF position, the controller may operate.
The system operating lamp lights up at this time, but it is not a failure.
• After the starting switch is turned to OFF position, if the system operating lamp stays lit for a long time, con-
sult your Komatsu distributor.
• The system operating lamp may look slightly luminous in the dark when it is not lit. It is due to the minute
leakage of current and this is not an abnormal phenomenon.
