Lifting Height Limit
Move the boom to the desired height, and press the lift-
ing height restriction key. The lifting height restriction
indicator lamp will flash and the buzzer will sound con-
tinuously, indicating that the limit height has been
registered in the memory. When the boom is moved
back to a height within the set limit, the lifting height re-
striction indicator lamp stops flashing and stays
illuminated and the buzzer stops.
Thereafter, the lifting height restriction indicator lamp
flashes and the buzzer sounds continuously whenever
the height limit previously registered is reached.
To cancel the height limit function, press the lifting
height restriction key again. The corresponding lifting
height restriction indicator lamp will go off.
Swing Limit
Swing the boom to the desired position, and press a
swing restriction key. The corresponding swing restric-
tion indicator will flash and the buzzer will sound
continuously, indicating that the swing angle limit has
been registered in the memory. When the boom is swing
back to an angle within the set limit, the swing restriction
lamp stops flashing and stays illuminated and the buzzer
stops. Thereafter, a swing restriction indicator lamp
flashes, the swinging boom stops automatically, and the
buzzer sounds whenever the limit previously registered
is reached. To cancel the swing limit function, press the
corresponding swing restriction key again. The corre-
sponding swing restriction indicator lamp will go out.
◆ When registering the swing angle limit, register both
the right and left boom swinging restriction positions.
Registering only one side cannot fulfill this working
range limit function nor make the alarm buzzer sound.
◆
In case that the swing stop override switch is set to
"OFF," the swinging boom will not stop automatically
even when the limit previously registered is reached. Be
very careful in performing swing operation as only the
swing restriction indicator lamp flashes, a message is
displayed, and the AML buzzer beeps for three seconds.
