4. HANDLING OF MOMENT LIMITER OPERATION
4.1.1 Switches on Display Panel of Moment Limiter

WARNING
Set the moment limiter correctly for respective crane works. The moment limiter calculates
the moment based on this setting.
Pay enough attentions to this setting because the setting not corresponding to the actual
crane work neither give an advance warning nor stop the boom automatically when a load
becomes close to the overload magnitude.
[1] Fall mode selector switch and hanged wire count display LED (amber)
These are used for changing the hanged wire count.
‡ Press the switch for two seconds or more.
The setting will be changed from “1” to “2”.
At the same time, the One-Hanged wire count display LED sill be
turned off and the Two-Hanged wire count display LED will be turned
on to notify the setting change.
‡ After that, each time pressing the switch for two seconds or more the
hanged wire count setting will be changed from “2” to “4”, then from
“4” to “1”, and from “1” to “2”, cyclically.
NOTES
When changing the setting continuously, move your hand off the switch once and press it again.
[2] Boom angle upper limit switch and LED (red)
These are used when setting or canceling the boom angle upper limit.
具
SETUP
典
In the status where the upper limit is not set, set the angle for the boom
and press the switch for two seconds or more. This boom angle is set
as the upper limit.
At the same time, the LED comes on to notify that the upper limit has
been set.
To enable this setting, set the key switch to OFF once, and then set it to ON. Another way to enable this
setting is to lower the boom 10° or more under the specified angle to place the boom out of the advance warning
range while the engine is running.
NOTES
Before starting the actual work, be sure to check if the boom automatically stops at the specified angle. If the
boom does not automatically stop, set the boom angle again by implementing the above procedure.
If the boom enters the advance warning range or stops due to the upper limit restriction in the status where
the boom angle upper limit is set, the boom angle upper limit LED will blink.
具
CANCEL
典
Press the switch for five seconds in the status where the upper limit is set (the LED is lit). And then the current
upper limit setting will be cancelled.
At the same time the LED will be turned off to notify that the upper limit setting has been cancelled.
NOTES
Keeping pressing the switch for two seconds or more does not repeat setting and canceling procedures. To change
the procedure, move your hand off the switch and press it again.
