Gear Up - Output Off - PowerBox Systems Mercury SRS Instruction Manual

The positional values vary according to your linkages, and must therefore
be set individually to suit the specific model. It is important to ensure that
the wheel doors do not jam mechanically. The times stated in our example
are also just an illustration, and need to be set to suit your preference.
The timing of the tasks does not need to coincide with the task numbering.
For example: it is permissible for Task 5 to occur before Task 2.
Our example clearly shows how the function is built up. Additional
movements or intervals between opening or closing the wheel doors can
be inserted at any time; all you have to do is set up a new free task. This
freedom is intended to remove all restrictions which might otherwise
prevent the model's undercarriage retracting and extending in the exact
scale manner.
Important: the first START POSITION in the UP » DOWN sequence must
always coincide with the last STOP POSITION in the DOWN » UP sequen-
ce. This means: intermediate steps can be made individually, but the final
task must always take the servo back to its starting position!
Caution: if you notice unusual or unexpected servo movements in the
sequence, you need to check your tasks!

- GEAR UP - OUTPUT OFF:

The door sequencer of the Mercury SRS includes a further auxiliary
function which makes it possible to switch off a channel when the
undercarriage is retracted. For example, the nosewheel should not
deflect in parallel with the rudder when the undercarriage is in its
retracted state, as this could jam the system mechanically; this function
solves the problem.
At this menu point simply enter the output which you wish to switch off as
soon as the undercarriage is retracted. When you confirm your choice by
pressing the SET button, the unit stores the position of the nosewheel
which it is to adopt when the wheels are raised.
Caution: once you have completed the set-up procedure, it is important to
check all the model's control surface systems with the undercarriage both
retracted and extended. For example, if you were accidentally to assign
the GEAR UP - OUTPUT OFF function to the elevator output, then your
model would surely be wrecked immediately after take-off!
