there are two units with the same frequency, these may interfere with each other but can never act
on the other crane, as they will have different ID codes.
2.9.- THE TABLE
This is the relation that exists between the input made on the mechanisms of the
transmitter, with the activation and de-activation of the output relays of the receiver.
There can exist infinite combinations; each time a table is created for a crane, it is assigned
a table number. If we install a unit in a standard crane the table will already be created.
There exist multi-table units; as their name indicates, they are able to work with several tables after
selection from the eeprom70 programme.
From the eeprom70 programme, it is also possible to import tables, that is, copy to one unit
the table of another. It is recommended that we import tables only when we know that the unit to
which the table is imported, like the unit to which the table is exported, have the same mechanical
configuration.
2.10.- OPERATION MECHANISMS
These are the mechanisms which the crane operator may use to carry out a manoeuvre.
Generally, the button panels and control desks use different mechanisms; the most usual
ones are:
Button Panel: Button 0-1 , two speeds
Selector 1-0-1 mechanism without return to zero
Key 1-0-1 mechanism with return to zero
Desk: Button 0-1
Key 1-0-1 mechanism with return to zero
Key 0-1 mechanism with return to zero
Selector 1-0-1 mechanism without return to zero
Selector 0-1 mechanism with return to zero
Electric key with 2 shafts
Analogical key with 1 shaft
Optical controller
Note: For more information on the mechanisms, consult the list of parts for each model.
2.11.- SELECTOR MASKS
Manoeuvres which carry out a movement are considered to be active manoeuvres.
