Terminating the Operation
Precautions for Terminating the
Operation by the Transmitter
• Before stowing the boom, switch the operation
mode to "CRANE MODE" and confirm that the
mode is switched correctly.
• Before stowing the outriggers, ensure that the
boom and the hook is stowed in the correct
positions.
• Before stowing the outriggers, switch the
operation mode to "OUTRIGGER MODE" and
confirm that the mode is switched correctly.
• When all the operation by the Transmitter is
complete, always turn OFF the power of both
the Transmitter and Receiver.
• On no condition, Transmitter will be ON unless
the Crane is in operation, otherwise,
unexpected touch or contact of operation levers
or buttons of the Transmitter to any other object
may cause un-desired motion of the Crane and
a serious accident such as tipping or collision
may occur.
• Where it is required to turn ON the Transmitter
for the purpose of inspecting it or such, always
keep the Receiver OFF and stop the engine, as
well.
REMOTE CONTROL
SYSTEM FEATURES
This system is designed principally for the
following purposes:
This Interactive Remote Control System includes
both Transmitter and Receiver which facilitate
remote control of the Crane which is purchased
with this device.
This Interactive Remote Control System provides
an operation of the Crane at the most convenient
place away from it within a range of the length of
the connection cable. In addition, its LCD screen
indicates "Rated total load", "Actual Load" and
"Load factor (by a bar chart)", which ensures
proper operation based on these information.
CAUTION: The remote control system
provides following safety functions:
• Abnormal Signal Detector Circuit
When the Main switch of the Receiver is
turned ON this circuit checks the dispatch
of Crane operation signals for 3 to 4
seconds. Thus, the Crane will not be
immediately ready for operations.
When dispatch of any crane operation
signals are noticed, power will be
automatically OFF and the Crane stops.
For resume, push the Reset button of the
Transmitter.
• Automatic Power OFF Circuit
Power of the Transmitter will be
automatically OFF when the remote control
of crane operations is discontinued for the
specific time.
For resume, push the Power switch of the
Transmitter to turn ON.
• Voltage Drop Limiter (for the Receiver)
The Receiver will be automatically shut
down in the event where the voltage of the
battery drops below DC 7 volts.
This prevents malfunctions of the Crane
due to voltage drop and the operation will
resume automatically when the voltage is
restored to DC 7 volts or higher.
