13. A FAIL-SAFE
CTIVATING
The effect of the FAIL-SAFE settings is that the servos (etc.)
take up a pre-defined position, previously stored in the receiver,
if interference occurs.
If FAIL-SAFE has not been activated (factory default state, or
after a RESET ( 15.), the signal is switched off after the HOLD
period (0.5 sec.). This means that the servos become "soft" and
remain in their last commanded position under no load (this may
equate to full-throttle!) until a valid signal is picked up again.
! Note:
In the interests of safety we recommend that FAIL-SAFE should
always be activated, and the FAIL-SAFE settings should be
selected so as to bring the model to a non-critical situation (e.g.
motor idle / electric motor OFF, control surfaces neutral, air-
brakes extended, aero-tow release open, ...).
Sequence
1. Switch on the transmitter, then the receiver. The LED
flashes:
1,6 sec
LED Code 3
2. Move all the transmitter sticks and other controls to the de-
sired FAIL-SAFE positions (e.g. motor idle, control surfaces
neutral).
3. Press the button briefly (approx. 0.5 seconds); the LED goes
out.
FAIL-SAFE is now active, and the FAIL-SAFE settings are
stored.
! Note:
If you hold the button pressed in for too long (> 2 sec. - until
the LED comes on), the IPD filter is switched off (
this case FAIL-SAFE is not activated, and the FAIL-SAFE
settings are not stored!
4. Testing the FAIL-SAFE settings
Move the sticks to positions other than the FAIL-SAFE
settings, then switch off the transmitter. The servos should
now move to the FAIL-SAFE settings previously stored, once
the HOLD period (0.5 sec.) has elapsed.
! Notes:
The FAIL-SAFE settings are only stored if the IPD filter is
active, and if no errors are displayed:
1,6 sec

If you change the transmission mode (e.g. by changing from
PPM 6 PPM 7, PPM 7
FAIL-SAFE positions (see also
The FAIL-SAFE settings must always be checked and
brought up to date if, for example, you install the receiver in a
new model, or make an accidental mistake in programming
the receiver ( 13.4).
The maximum FAIL-SAFE duration is limited to 15 seconds.
After this the servo signal is switched off
come "soft", an electric motor speed controller switches off
the motor in the absence of a signal.
This eliminates the danger of jammed mechanical linkages
stalling the servos (e.g. after a collision), which would usually
wreck them.
If FAIL-SAFE has not been activated, servos with their own
HOLD or FAIL-SAFE function (e.g. MULTIPLEX mc and
mc/V2 series digital servos) do not become "soft" after the
HOLD period has elapsed.

WITCHING OFF THE
The IPD filter ( 12.) can be switched off if necessary. In this
mode the receiver operates like a conventional FM/PPM unit, i.e.
the signals picked up are passed directly to the servos (etc.).
This can be useful, for example, to locate sources of problems to
the receiver caused by the power system, or the arrangement of
the receiving system components. The filter should always be
switched off for range-checking, so that it does not filter out any
interference (undesirable in this case). Changes can then be
made as required.
Sequence
1. Switch the transmitter on, then switch the receiver on. The
LED flashes:
1,6 sec
LED Code 3
2. Press the button (the LED goes out), and hold it pressed in
until the LED comes on again (after about 2 seconds).
The LED then flashes as follows:
1,6 sec
LED Code 4
You can re-activate the IPD filter by either of the following
methods:
Switch the receiver off, then on again
or
Hold the button pressed in again for >2 seconds (see above)
! Note:
In the interests of safety the IPD filter should only be switched
off for range checks or other experimental purposes. Normal
operations should always be carried out with the IPD filter
activated.
15. R RESET
ECEIVER
The receiver settings can be switched back to the factory default
values. All settings (e.g. RF channel, FAIL-SAFE settings) are
lost when you do this, and are reset to the factory defaults.
Sequence
1. Switch the transmitter on, then switch the receiver on. The
LED flashes:
1,6 sec
LED Code 3
2. Press the button and hold it pressed in until the LED goes
out - after about 10 seconds.
The LED now flashes the confirmation signal:
1,6 sec
LED Code 5
The signal output is switched off after you carry out a RESET.
The receiver can only be used again after switching it off, then
on again ( 10.).
A RESET can also be triggered without a transmitter signal. For
this to work an RF channel must have been set previously.
