Command change between control stands
For a command change to a different control stand, there are two variants which have to
be set using DIP switch I–2 in the setting unit. Command change with lever comparison
or free command change.
On twin-engine systems, both setting units must have the same setting.
. “Command master calibration and enable of control stands” must have been
carried out.
Otherwise, the command can not be changed between the individual control stands.
Command change with lever comparison
The control system compares the lever positions of the command masters involved in the
control stand change. A command change from one control stand to another can only
take place if the lever of the requesting command master is either in the “Neutral posi-
tion” or in the same travel direction position as the lever of the command master that
is in command.
The command change for this variant takes place in two steps.
1st step: Command request on the selected control stand.
Execution: – Set the control lever of the command master in the takeover position
(“Neutral” position or same travel direction as the
command master that is in command).
– Press “Command” key once to request the command
on this control stand.
Consequence: – The acoustic signal transmitter “beeps” in short intervals.
– The display “Command” flashes rapidly.
The command is now requested on this control stand. The control system has enabled
the command takeover and indicates this by means of short tone and lamp intervals.
. If the control system issues long lamp and tone intervals, the subsequent command
takeover is refused. In this case, the control levers of the command master are usually
not in the correct position or there is a fault in the system.
