Smallest "Programmable"
(Meter, Gauge, Annunciator, or EIS)
Display almost anything in
your aircraft in about the size of a
postage stamp!
It functions as a meter, gauge, annunciator, and even
can function as a small EIS.
The display is green, yellow or red. Caution and
Warning screens; yellow and red.
Alarm screens will flash if needed
with an audible output.
Flash and audible alarm delays up to 409 seconds
(6 Min. 49 Sec.) can programmed.
Weighs only 5.0 oz. (142grams) !
Model: AG6
If you desire to also monitor OAT, CHT, EGT, or thermocouple inputs, please choose our Model: AG6T.
It has the same features as the AG6 with up to six thermocouple inputs.
The AG6 is a full
service Aircraft Annunciator, Fuel Gauge, Oil Level Gauge, Volt Meter & Current
Meter. The annunciator will display many different
aircraft warnings. All devices feature user programmable alarms.
The AG6 utilizes a push-button LCD display that is backlight with a 3 color LED. All functions
are fully programmable by the user. The push-button/display can be used
for programming, acknowledging the alarms, and paging thru up to 16 different
screens or "annunciator points". The AG6 can automatically scan thru each
screen or it can be done manually using the push-button. The pilot
has the ability to mask or unmask annoyance alarms.
NOTE: Input
devices not included.
It is up to the user to provide input devices such as fuel senders, shunts, oil
level sensors and input switches to drive the AG6.
INSTALLATION MADE EASY
DISPLAY & PUSH BUTTON
The display can be easily mounted in the panel anywhere you can make a
rectangular
hole. It is a snap to install !
Measures 1.25" wide by 1.0625" high by 1.375" deep, including bezel
housing
ELECTRONICS ENCLOSURE
Signal input/driver board mounts lower in the instrument panel for easier wiring.
This permits a better location of inputs & connections in a crowded aircraft.
It measures 4.25" x 3.35” by 1.45" high.
RIBBON CABLE
The 36" ribbon cable makes it easy to install and remove if necessary.
Plugs are provided at both ends.
FEATURES:
INPUTS
The AG6 will
accept up to 6 input signals. (If the audio output is used, only 5 inputs are
available.)
All inputs will
accept signal ranges from (0 to 0.200V) to (0 to 16.383V) for the AG6-12V model
and (0 to 0.400V) to (0 to 32.76V) for the
AG6-24V model. Inputs can come
from simple on/off switches, aircraft shunts, resistive sensors such as fuel
senders, or analog signals from other equipment. The AG6 is compatible
with capacitance type fuel or oil senders as long as the sender's output is a
current or voltage proportional to the fuel or oil level quantity. All inputs can be
configured for a filter or delay. These filter time constants are fully
programmable. Filtering may be used to eliminate noisy signals and/or
lengthen signal response times.
NOTE: Input
devices are NOT included. It is up to the user to provide input devices
such as fuel senders, shunts, and switches to drive the AG6.
SHUNT INPUT
There is one special input for a
shunt. It can be used to monitor aircraft current. This shunt can be placed in aircraft's
plus or minus leg of the power circuit. No isolation is necessary. This input will accept
signals from (0to 0.050V) to (0 to 0.250V). This is the range of most
aircraft shunts. NOTE: If this input is utilized, input terminal
#5 cannot be used. The shunt signal will become input signal #5.
ALARMS
When there is a valid alarm, the display screen will blink. If the audio output
option is selected, it also will sound. The pilot can temporarily mask or
switch off any annoyance alarms using the push button. When the alarm is
masked, the display depicts a little triangle in the upper right hand corner of
the screen. It can also be easily turned back on. The annunciator
features two, three, four, or five zone alarms for maximum flexibility.
All alarm set points and alarm delays are fully programmable.
Have you ever left your Fuel Pump on
too long?
The alarm delay is programmable from 0.0 to 409.0 seconds (6 Min. 49
Sec.).
This allows you to program this annunciator for a wide variety of
applications
such as this one. For this one, just wire the AG6 to your fuel
pump switch.
SOUND OUTPUT
An audio output is also provided when
there is a valid alarm. This output can be wired into the aircraft’s sound
system.
An on board amplitude adjustment is provided.
NOTE: If the sound output
option is utilized, only 5 inputs will be available. Input terminal #6 will be used
for the sound output.
DISPLAY & DIMMING
The push button display is an LCD display that is backlight with an LED. The LED
color can be green, red or yellow.
Screen colors are fully programmable. Green is used for a normal
condition, yellow for caution, and red for the alarm.
The screen brightness control can be tied to aircraft's instrument lighting dimmer.
PUSH BUTTON COMMANDS
Since the AG6 utilizes one button for entering all commands,
commands are entered in a simple combination of long and short button presses similar to Morse
code. The manual provides a cheat sheet that you may copy to include it in
the aircraft and aircraft handbook.
GAUGE CHARACTERISTICS
Operation of the fuel gauge is depicted below. When the fuel
reaches a low level caution point, the display is yellow. When the fuel
reaches the low fuel point, the display blinks red. The pilot can
acknowledge the alarm by pressing the button. The alarm will stop flashing
but will remain red. The audio output will also stop.

OPERATION
EXAMPLE
as fuel is run out
The full scale and zero offset of the input signal can be programmed
for each gauge.
NOTE: The AG6 Fuel Gauges and the Low Oil Level Gauge assumes a linear input
signal is provided. Most capacitive type senders
can be calibrated to yield a linear output signal. If your sender is
calibrated linear, the AG6 will display a linear representation.
INPUT POWER
Input power can be either 10 to 15Vdc or 20 to 28Vdc nominal. Current draw is less than 0.060A (60mA) with
the LED back light on.
OPERATION
There are two different operating modes, manual and automatic. In the
automatic mode, the AG6 automatically scans thru each point or screen and then
starts over again. The manual mode operates in a similar fashion except
that the user can use the push button to toggle thru the different screens
stopping at any screen. You can easily switch from mode to mode
using the push button.

PROGRAMMING ASSISTANCE
If you are not a gadget person and would like to
simplify the programming, order the AG6 from Aircraft Extras, Inc. web site and
request that we pre-program it you. We will contact you by e-mail or phone
and discuss the details of your project. We can also create custom
screens if you do not see what you want from our pre-programmed screens. A
small additional charge may be applicable.
PROGRAMMING:
All functions are fully programmable thru the AG6 push button. Some of
