7.16 Fail-Safe settings (F/S)

This function is only available in PCM
mode; you must first set the transmit-
ter to this modulation  (see Section
7.1.1, Parameter menu). The model
must be fitted with a robbe-Futaba
PCM receiver.

In the Fail-Safe menu you can carry out the following adjustments
for channels 1…8.

1."NOR" (Normal), or Hold mode.

The receiver stores the last error-free signals, and passes them on to
the servos if interference occurs.
These signals are maintained until valid signals are picked up again
from the transmitter.

2. (F/S) Fail-Safe position.

In this case the servos run to a position pre-programmed at the
transmitter; these values are also stored in the receiver. As standard
the fail-safe value for the throttle channel is activated at a value of
20%.

A "Battery fail-safe" function is also available.

As soon as the voltage of the receiver battery falls below a value of
around 3.8 V, the throttle servo runs to a pre-set position (20%) in
order to indicate to the pilot that the model’s receiver battery is
dangerously low.

You must land immediately if this should occur.

The battery fail-safe function can be reset for a period of 30
seconds by moving the throttle stick briefly below the pro-
grammed fail-safe position. The throttle servo will then revert to
the pilot’s control. This can be repeated as required.

This function is active even if you do not program a F/S setting
for the throttle channel.

Don’t set too low a value for the throttle, otherwise the motor could
stop at an awkward moment. The default value of 20% can, of
course, be overwritten.

The F/S settings should be carried out separately for each model
type. For example, a helicopter should be set to a safe hover, whe-
reas a fixed-wing model should be set to a broad turning pattern.
Program the settings which allow the model to fly by itself for a
while in an inherently stable flight attitude. This should allow the
model to survive unscathed if brief interference strikes, until con-
tact with the transmitter is restored.
You can check the settings by switching off the transmitter, and
watching the response of the servos in the model.

The Fail-Safe settings are automatically transmitted to the
receiver at intervals of about 60 seconds.

To ensure that the data is actually stored in the receiver, you should
wait for at least 60 seconds between switching on the transmitter
and operating the model.

-

Move to the Select menu "F/S".

-

Press the 3-D hotkey briefly to move to the Setup menu.

-

Use the "S" and "H" buttons to select the control channels which
are to be set to Fail-Safe (F/S).

-

Rotate the 3-D hotkey clockwise to activate the Fail-Safe option.
If you wish to revert to the basic setting (NOR), turn the 3-D hot
key to the left.

-

The triangle symbol shows the status of each control channel.

-

Now move the sticks for all the channels for which an F/S setting
is to be made to the desired Fail-Safe position 

simultaneously

,

and hold the 3-D hotkey pressed in for at least 1 second to store
the settings.

General notes on the Base program

The options listed for the ‘BASC’ mixer program are also available in
the special programs (ACRO, GLID and HELI).
As a general rule you can make use of additional, model-specific
functions by selecting the special programs; these are in addition
to those in the Base menu.
The expanded functions are included in the rotation loop, and can
be found in the screen sequence before the menu point PARA.
