[1] DESCRIPTIONS OF SWITCHES ON MOMENT LIMITER DISPLAY UNIT
1. WIRE ROPE FALL MODE SELECTOR SWITCH AND WIRE ROPE FALL DISPLAY LED (GREEN)
When entering the number of wire rope falls, verify the actual number of wire rope falls and
make sure to set up correctly. Failure to set the correct wire rope fall (s) may result breakage of
the winch wire ropes and cause a serious accident.
Use this switch to change the number of wire falls.
• Keep pressing the switch for 1 second or more.
The setting changes from “4-falls” to “1-fall”.
At the same time, the wire fall display LED changes from “4-falls”
to “1-fall”, indicating that the setting has changed.
• After that, keep pressing the switch for 3 seconds or more, then
the setting changes from "1-fall" to "2-falls", and "2-falls" to
"4-falls" in every 1 second.
NOTES
When changing the setting right after doing so, release your
hand from the switch, and then press the switch again.
2. BOOM ANGLE UPPER LIMIT SWITCH AND LED (GREEN)
Use this switch to set or cancel the boom angle upper limit.
[SETUP]
With no upper limit value being set, set the boom to the angle you
would like, and press the switch for 3 seconds or more.
The boom angle at this point is set as the upper limit.
At the same time, the LED flashes indicating that the upper limit
value was set.
NOTES
• Be sure to verify that the boom automatically stops at the set angle before performing the actual
operation. If the boom does not stop automatically, re-set the boom angle using the procedure above.
• Whilst the boom is within the pre-warning zone or at the upper limit, the warning buzzer sounds
intermittently, only when the boom derricking operation is attempted.
• The limit value being set is retained in the memory even when the starter switch is turned to "OFF"
(cut).
When the boom reaches the pre-warning zone or stops at the upper limit with the boom angle upper limit
set, the boom angle upper limit LED flashes.
[CANCEL]
With the upper limit value being set (LED ON), press the switch for 3 seconds or more.
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 3 seconds or
more. Let your hand go off the switch and press the switch again.
