4. WORKING RADIUS UPPER LIMIT SWITCH AND LED (RED)
Use this switch to set or cancel the working radius upper limit.
[SETUP]
With no upper limit value being set, set the boom to the working
radius you would like, and press the switch for 2 seconds.
The working radius at this point is set as the upper limit.
At the same time, the LED lights up indicating that the upper limit
value was set.
To enable this setting, turn the key switch to the ON position again after turning it to the OFF position, or
reduce the working radius by
“1.3 m” or more from the set working radius to get out of the pre-warning
zone while the engine is being started.
NOTES
Be sure to verify that the boom automatically stops at the set working radius before performing the
actual operation. If the boom does not stop automatically, re-set the working radius using the procedure
above.
When the boom reaches the pre-warning zone or stops at the upper limit with the working radius upper
limit set, the working radius upper limit LED flashes.
[CANCEL]
With the upper limit value being set (LED ON), press the switch for 5 seconds.
The current upper limit value setting will be cleared. At the same time, the LED goes off indicating that the
upper limit value setting is cleared.
NOTES
The setting and canceling will not repeat even if you keep the switch pressed for more than 2 seconds.
Let your finger go off the switch and press the switch again.
