The positions of the undercarriage control system and all the wheel doors are
now set up in accordance with the number of wheel doors you have entered. At
this point you should connect the retract control unit and the wheel doors to the
appropriate output of the PowerBox Mercury SR2. Starting with A the Assistant
searches for outputs which have no special functions – i.e. Direct xy outputs,
which are not assigned to a gyro or other sequencer function.
When the positions are being established you will see that the wheel doors and
the undercarriage itself always follow the cursor position, and slowly approach
the set position. If you wish to adjust these positions, press the SET button and
make changes using buttons I and II. Select Finished to adjust the other wheel
doors. Once all the doors are correctly adjusted, the following display appears,
and you may be asked to move the retract switch to Extended:
The Assistant now opens all the wheel doors and moves the undercarriage to the
Extended position. At this point you can check the operation of the sequencer by
operating the retract switch on the transmitter. If you nd a problem - perhaps
the pause between the undercarriage and the wheel doors is too short - you just
select the Assistant again, and change the appropriate setting. There is no need
to re-adjust the wheel door positions.
Should you wish to set up additional wheel doors or travel points, you can do this
at any time in Manual Setup.
Note: It is important to keep to the standard sequence when installing the
PowerBox Mercury SR2 for the rst time:
Setup Assistant (Basic setup) –> Sequencer Assistant –> manual output as-
signment of all other functions.
If you ignore this, the Sequencer Assistant could overwrite Direct functions
which are already assigned.
