3. the HXr The EIS is connected to the HXr through one of the serial ports Some sensors have the option of being wired directly to the EFIS system For example fuel level probes can be connected directly to the HXr using the Analog inputs Outside Air Temperature OAT can be wired directly to the AHRS or the EIS Blind Mounting the EIS The EIS does not have to be mounted to the instrument panel face Due to the size of the HXr many builders choose to mount their EIS in a tucked away location that is accessible only for initial programming Because warnings on the EIS can not be canceled in flight if the unit is out of pilots reach the HXr is programmed with all of the engine limits and the EIS limits are set to 0 with few exceptions The EIS will send all of the raw sensed data to the HXr which then detects any out of limit parameters and displays a warning for the pilot Warnings on the HXr are acknowledged by pressing the yellow MSG softkey Monitoring Oil Pressure at Engine Start The HXr should not be wired to the master circuit because of possible current spikes during engine start However the EIS will not be bothered by these spikes and should be wired to the master for the sole reason of showing an oil pressure reading during engine start The minimum oil pressure limit should be set in the EIS regardless of whether the unit is blind mounted A simple warning light can be wired to the EIS and placed on the instrument panel
4. the Resistive Float Senders Supplement for Horizon also available on the GRT website under EIS Documentation This is a great time to backup all of the EFIS settings onto a memory stick NOTE We do not recommend using the Backup Settings feature to program Engine Limits and Graphical Engine Display in a second or third EFIS because it will overwrite ALL settings in the display unit Usually it will cause some critical settings such as serial port assignments to be overwritten and cause more work than it saved To backup EFIS settings a Insert the USB thumb drive into the display unit b Go to SET MENU gt DISPLAY UNIT MAINTENANCE c Right at or near the top is EFIS Settings Backup Highlight this and push the knob d Highlight Backup All Settings and push the knob Answer YES at the prompt The system will back up all the display unit s settings onto the USB drive e If it ever becomes necessary to restore your settings use the Restore All Settings option Horizon HXr User Manual Draft Revision Al JAR A 2 2 Data Sets and Location Options Each x marks a location that the Data Set can be displayed Gray shaded data sets are always visible in the Fixed Data Box on the ENG MAP screen Sensors listed may not apply to all engines Revision A1 Data Set Air Pressure x lt m Carb Temperature Amp2 CHT 1 CHT 2 Coolant Temperature Density Altitude EFIS Power Bus 1 Volts EFIS Power Bus 2 Volts EFIS Po
