Precautions for Terminating the
Operation by the Transmitter
WARNING!
• 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 the 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.
