LOCKING/UNLOCKING THE HAND CONTROLLER
The hand controller can be locked to prevent unauthorised
persons, such as children, from starting the hand controller
and operating the crane. (Figure 1)
Locking the hand controller
- Press the EXTRA button and the ON-OFF button
when the stop button is pressed in.
- Continue to hold the buttons pressed at the same time
as the stop button is pulled out.
The centre display will now show a locked padlock.
Note!
If battery power drops too low the hand controller will
lock automatically.
Unlocking the hand controller
- Press the EXTRA button and the ON-OFF button
when the stop button is pressed in.
- Continue to hold the buttons pressed at the same time
as the stop button is pulled out.
The hand controller is ready for use.
LOW AMBIENT TEMPERATURE
The LCD-type displays on the hand controller are
somewhat slow in changing state in low temperatures.
At 0°C, it will take approximately 1 second, and at
-20°C it can take up to 8 seconds before the symbols
have completely updated.
For safety reasons, quick shifts within a menu are
not possible at temperatures below -10°C; though
shifting between different menus will still be possible
as normal.
To avoid the inconvenience that may be caused by
the above, the hand controller should be stored at a
temperature above +10°C when not in use.
NO SIGNAL FROM THE SAFETY SYSTEM
If a fault develops in communication with the safety
system during operation, the system stops the crane. The
centre display shows the spanner symbol to indicate that
there is a fault. The crane can only be operated manually
under emergency conditions if this occurs.
REPLACING A HAND CONTROLLER OR DECODER
Every system has a unique controller/decoder pair which
only communicates with each other. If one unit has to be
replaced, a special procedure must be followed to make
the new pair communicate. The procedure is as follows:
1. Switch off the PDB's system.
2. Unscrew the left-hand connector on the decoder and
remove it.
3. Connect the hand controller with the accompanying
cable (E0781) to the decoder.
4. Switch on the PDB and select "remote".
5. Hold down the release button on the hand controller
while pulling out the stop button.
When the yellow LED on the decoder starts to blink, let
go of the release button. When the procedure is complete,
the yellow LED goes out. If the procedure was successful,
only the green LED remains lit, if not, the red LED is lit.
The procedure can take up to half a minute.
