WARNING!
DO NOT PRESS AND HOLD THE PROG BUTTON DURING THE NORMAL OPERATION
(FLYING, DRIVING, ETC.) OF YOUR R/C DEVICE!
4.2 Setting the Failsafe
If no failsafe is programmed, the servos will hold their last known valid state when a failsafe
condition occurs. The default failsafe time is 2 seconds.
You can program the failsafe condition for each channel using the XZ-P1Programmer or XZ-T1
Telemetry Station devices. Once you have set the failsafe map conditions, you can then set the
user defined channels. To do this, turn on the Graupner|IFS system so that servos can be
moved. Now, connect binding plug to the port labeled "B" until the LED is off. Now remove the
binding plug. Now the STATUS LED starts flashing for about 8 seconds. During this time, move
your sticks and switches to where you would like them during a failsafe condition.
NOTE – Only those channels programmed in the failsafe map will change to a user defined
position. All other channels will hold their last positions when a failsafe occurs.
WARNING!
PLUGGING A BATTERY INTO THE PORT LABELED 'B' WITH THE POLARITY REVERSED
WILL RESULT IN UNPREDICTABLE OPERATION! THE RECEIVER WILL POWER UP, BUT
SERVO CONTROLS WILL NOT FUNCTION PROPERLY. TWITCHING SERVOS, BLINKING
RECEIVER LED AND OTHER ODDITIES WILL BE SEEN. RANGE WILL BE UNUSABLE,
EVEN IF A RANGE CHECK SHOWS RANGE TO BE NORMAL.
5. POWERING THE SYSTEM
The Graupner|iFS-system is a computer controlled device. Just like your home PC, power is the
most critical link to success or failure.
Graupner|iFS-transmitter modules can use the standard transmitter battery. Nothing else is
required.
Graupner|iFS-receivers must be powered properly! With today's high torque digital servos, the
load on the flight battery can be extreme. It is not uncommon to see many amps of current draw
during flight.
You must use a power source that can provide the proper voltage when there is a heavy load.
Even small servos like the Graupner/JR DS-281 can draw up to 0.7 of an amp when stalled.
Four of these servos in a "foamie" can technically draw 3 amps of current, not including the
current required for the receiver.
For
years
people
have
been
claiming
radio
"failures"
or
"hits"
with
their
35MHz/36MHz/72MHz/75MHz systems that have actually been power related and not due to
signal loss. The XR -12DXT IFS, XR-12DX IFS or XR-12DXS IFS receivers use the latest
technology to safely operate down to 2.1 V, well below the operating voltage of any servo.
5.1 Recommend Power Setups for Graupner|iFS-Receivers
4 cell packs:
4 cell packs will work fine with Graupner|iFS-receivers providing you have adequate capacity.
The rule that we use is no less than 350mAh for each analog servo and no less than 500mAh for
each digital servo. So, in a typical 4 servo analog setup, a 1400mAh 4 cell flight pack would be
the absolute minimum we would recommend. Yes, you could probably get by with a lower
