2.20 Multiple station system
In normal operation control is accessible from every
control unit connected to the autopilot system. One
control unit is "active" and provides the user with
access to all functions. All remaining control units
are "inactive" and have no effect on mode changes or
course selection. A single press on any of the mode
buttons on an "inactive" control unit will allow
transfer of command and make it "active".
2.21 Lock function
The "LOCK" function is a safety feature in the autopilot system.
It will disable all control units, including the FU25 Follow-up
lever, except for a single user selected control unit location.
When the "lock" function is in use, no transfer of command can
take place; only the active control unit stays in command.
To enable the "lock" function, make a quick double press on the
STBY button.
The display on the active control unit will first show a
icon
and then the icon will alternate with the mode index.
The "locked" control units in the system will show:
The “Lock function is disengaged by one of the following
actions:
• The active control unit unlocks the other ones and makes them
“inactive” by another double press on the STBY button. It
also displays the
icon before it returns to the normal active
state.
• The system is switched OFF by any
control unit (press STBY
for 2-3 seconds).
