. "Command master calibration and enable of control stands" must have been carried
out.
Otherwise, the command can only be taken over at control stand 1.
Execution: − Set the control lever of the command master to the "Neutral position".
− Press "Command" key once for command request.
Consequence: −
Display "Alarm" (red) on all control stands remains lit up continuously.
− Acoustic signal transmitter sounds with fast intermittent tone on all
control stands.
− The display "Command" flashes rapidly.
. If the control system continues to issue long lighting and tone intervals, it is usually the
case that the control lever of a command master is not in the "Neutral position".
3. Command takeover:
Execution: − Press "Command" key once again for confirmation of command re-
quest.
Consequence: − Display "Alarm" (red) goes out on all control stands.
− Acoustic signal transmitter remains silent on all control stands.
− "Command" display shows continuous light on the command master in
command.
On all other command masters, the "Command" display is off.
The command is now at this control stand. The control system is ready for operation
(standby).
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.
