6.4.5 THE KEYBOARD – RADIO TRANSMITTER
(Pict.10)
The operator interface is identical to the
abovementioned one.
The differences are:
-
The absence of the integral cable,
replaced by a connector at the base of
the handgrip to connect the battery supply
serial cable (
1
). This 2 m. cable is
included in the standard supply and it
charges the keyboard batteries; it can also
be used to control the crane through cable
system. A 10 m cable is available upon
request; it can be used to work on areas
where the radio control is forbidden.
-
an additional selector for optional
functions (OPT1 and OPT2).
-
The rechargeable batteries that are
housed on a specific compartment (2)
protected by the keyboard and that can
be easily extracted disconnecting a quick
connector. Battery recharge may last up to three hours if batteries are completely flat. For this purpose
a car battery charging cable that can be connected to the car lighter is also supplied.
-
The radio transmitter module.
-
A circular magnet, located on the rear that allows placing the keyboard on metallic surfaces.
WARNING
Verify the emergency button correct operation (5) before using the radio control.
The radio control must be turned off when operations are suspended by pressing the
emergency button (5).
The keyboard box must only be opened in case of repair or anomaly.
Check the emergency button operation as follows:
-
Start a function (ex. boom lift), checking if it is performed by the crane.
-
Press the emergency button and check if the previously performed action is immediately stopped,
otherwise stop the machine.
N.B. Never let the crane work with disabled emergency button.
WARNING
When the cable keyboard is not being used, it must be disconnected from the connector
located on the guard aside the unit where the protection cover will be screwed.
Press the mushroom button of the cable and radio keyboards after their use and before storing
them on a protected and safe place.
The radio keyboard batteries last from 12 to 24 hours depending on their use.
It is suggested to let the batteries discharge until they are completely flat before starting a new
recharge cycle.
