| 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). Inputs can come from simple on/off switches, aircraft shunts, resistive sensors such as fuel senders, or analog signals from other equipment. 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. 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. 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. INPUT POWER Input power is 12Vdc only. 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. | ||||||||
