This allows identical operation of the two panel switches between all instruments while still allowing multiple functions. This document is a generic outline of the functionality of the switches, based on the various functional states of the instrument. Top Button The top button is the action button. It invokes different screen displays, allows selection of values and increments or decrements values. Examples of these actions are: 1. Moving between display screens 2. Selection of an action from a menu 3. Changing a value from within the setup menus 4. Entering a value during flight (clock instrument only) Bottom Button The bottom button is the navigation button. It will allow the cursor on the screen to move between allowable selections. Examples of these actions are: 1. Selection of different cylinders (EGT and CHT) in the Single Cylinder mode 2. Selection of different tanks (Fuel Level) 3. Selection of limits and functional items from within the setup menus 4. Time field selection (clock instrument only) There is one exception to the functionality of the bottom button. This is from the Primary Display (the screen that first comes on from power up). Pressing the button will display the instrument core status and support data. General 1. Each specific instrument contains detailed button options within the Operations Guide. 2. During setup, instructions are provided on screen and use of the buttons is as noted in this document. FL202G Instrument Setup Document # S200-FL202G-004 Rev 1.1 09/18/2012 Page 1 of 2 Aerospace Logic Inc. 180 James Street South, Suite 205, Hamilton, ON, L8P 4V1, CANADA Tel. 416-628-0725 | www.aerospacelogic.com | Fax. 416-352-5854 WARNING THIS INSTRUMENT MAY ONLY BE INSTALLED ON CIRRUS SR20 AND SR22 SERIES AIRCRAFT EQUIPPED WITH CIES INC. FUEL SENDERS. IT HAS BEEN PRE-CONFIGURED FOR THIS INSTALLATION CONFIGURATION AND WILL NOT WORK CORRECTLY WHEN INSTALLED IN ANY OTHER AIRCRAFT. 1. Color indications of the level indication bars have been preset based on Cirrus data for the specific aircraft. These values of usable fuel are automatically set when the instrument is calibrated: a. For SR20: i. Red line less than 0.1 USG ii. Yellow line 0.1 USG to 8.2 USG iii. Green line for all quantities above 8.2 USG b. For SR22: i. Red line less than 0.1 USG ii. Yellow line 0.1 USG to 14.0 USG iii. Green line for all quantities above 14.0 USG 2. The fuel imbalance warning values have been preset based on Cirrus data for the specific aircraft. These values are automatically set when the instrument is calibrated: a. SR20 - 7.5 USG b. SR22 - 10.0 USG 3. This instrument requires calibration before it will function. To calibrate each tank you will be required to add fuel at TWO gallon increments, starting with the unusable fuel in the tank (the legal, zero fuel point). a. Place the aircraft in a level flight attitude and support the aircraft wings, if necessary. b. Drain all tanks to be calibrated. c. Disable any cross feed between tanks.

Place the unusable fuel in each tank to be calibrated. e. Complete the calibration process by following the interactive, instructions provided throughout the process on the instrument display (See 4). f. Calibration time is approximately one minute per two gallons of fuel. g. Note the calibration values on the provided calibration sheets. This value serves two purposes. i. It demonstrates a compliant installation, and ii. Provides a hard copy backup of all calibration data. h. It is not necessary to complete the full calibration at once. Calibration can be resumed at any point of the process by re-entering the setup. 4. To enter parameters and perform the calibration, proceed as follows: a. Turn off the power to the instrument b. Press and hold both top and bottom buttons and turn on the power to the instrument. c. When instructed, release both buttons. d. In the setup menus, use the bottom button to navigate and the top button to select an option. e. Follow the onscreen instructions to enter the correct operating parameters. NOTE: Depending on the installation orientation of the instrument the display may initially be upside down. The first prompt in the setup is to press the button at the top of the instrument. This will orientate it correctly. f. To perform the instrument calibration, follow the instructions provided on the instrument screen. 5. Once all calibration has been completed the instrument will be enabled and be ready for use.

Pre-Calibration Display – Default Screen FUEL INSTRUMENT NOT INSTALLED CORRECTLY FLIGHT PROHIBITED 2. Power Up / Default Screen Displays the fuel level in each tank. Colors are determined by the range values as set during installation. The quantity in each tank is permanently displayed beneath each indicator bar. A flashing yellow bar on either side indicates a fuel imbalance condition. The flashing tank indication will be that of the tank with the most fuel. Switch the fuel supply to that tank to begin burning fuel from the imbalanced tank. Once sufficient fuel has been burned to fall below the imbalance warning, the flashing yellow bar will return to its correct color indication for the specific fuel level. Imbalance limits are fixed values for the specific aircraft. Press the top button to move to the next display screen.
