1. INTRODUCTION Thank you for purchasing the Dynon Avionics EMS-D10. This section provides some important cautionary information and general usage instructions for this manual. Before You Fly We strongly recommended that you read this entire guide before attempting to use the EMS-D10 in an actual flying situation. Additionally, we encourage you to spend time on the ground familiarizing yourself with the operation of the product.
Introduction Warning Dynon Avionics’ products incorporate a variety of precise, calibrated electronics. Except for replacing the optional internal backup battery in EFIS-based products per the installation guide, our products do not contain any field/userserviceable parts. Units that have been found to have been taken apart may not be eligible for repair under warranty.
Introduction The following icons are used in this guide: Any text following this icon describes functionality available only with the HS34 HSI Expansion Module connected to your system. Any text following this icon describes functionality available only with the AP74 Autopilot Interface Module connected to your system. Any text following this icon describes functionality that is possible when multiple Dynon Avionics products are networked together via the Dynon Smart Avionics Bus (DSAB).
2. PRODUCT OVERVIEW This EMS-D10 monitors your engine and other vital aircraft systems and displays information in an easy-to-read format. This section provides a general overview of the various parts of the EMS-D10 as well as a theory of operation. The information in this section serves as a reference only and helps familiarize you with the inner workings of the unit. It should not be used for diagnostic or reparative work.
Product Overview DYNON SMART AVIONICS BUS If you have multiple Dynon Avionics products in your aircraft, they may be networked together via the Dynon Smart Avionics Bus (DSAB). Units networked via DSAB have the ability to transmit information to each other. Any product's data can then be viewed on any other screen in the DSAB network. For example, an EFIS has the ability to display engine monitor information if it is connected to an EMS or FlightDEK-D180.
3. PRODUCT OPERATION After reading this section, you will be familiar with the basics of how to use your EMS-D10. For details regarding specific procedures (e.g., adjusting display brightness, using the fuel computer, setting the clock, etc.) please refer to the EMS Operation section. Front Panel Layout All normal operation of the EMS-D10 happens via the front panel. The front panel contains buttons and a display. Buttons – There are six buttons on the front panel of the EMSD10.
Product Operation Display The EMS-D10 display is the most obvious and commonly used output of the device. It displays all EMS-related data and, when connected to other data sources, can display EFIS and HSI data as well. SCREENS AND PAGES The terms in the following bulleted list are used in this section and are defined as follows: Screen/Screen Configuration – Screens consist of one or two pages from the EMS-D10 or from another DSAB-connected Dynon Avionics product.
Product Operation The EMS-D10 has several pre-defined screen configurations. The basic layout of a screen configuration is represented by one of two icons on D10-series product. The table below shows the two icons and their meaning. The predefined screen configurations with their respective icons are as follows: Icon Left Page Area Right Page Area 1/2 1/2 One page that occupies all of the screen area The SCREEN LIST Menu uses icons to illustrate the layout for each screen configuration.
Product Operation CYCLING BETWEEN SCREENS There are two methods for cycling between pre-defined screens: via the menu and via hotkeys. Screen Cycling Using the SCREEN LIST Hold for two seconds Navigate to the SCREEN LIST menu by holding button six for at least two seconds when no menu is present (see the figure to the right). Note that if you only press button six momentarily, the display cycles to the next screen in your screen rotation. Use the DOWN▼/UP▲ buttons to move the caret (>).
Product Operation Changing the Screen Rotation You may use the out-of-the-box screen rotation or define your own. If you desire to use the initial rotation, no user configuration is required. If you desire to use a custom cycling order, then user configuration is necessary. To configure a custom rotation, navigate to the SCREEN LIST menu page by pressing button six for approximately two seconds when no menu is present.
Product Operation Menus All interaction with the EMS-D10 is accomplished through the use of its menu system. The menu system is accessed and navigated via the six buttons located on the front of the unit. PAGE-SENSITIVE MENUS On a screen where no menu is already present, buttons two through five are used to display a menu. With no menu displayed, pressing any one of these buttons causes the menu for the page above it to show at the bottom of the screen.
Product Operation If a menu contains more options than there are buttons, the MORE label is displayed over button five. Pressing this button shows you the next set of options in the current menu. In any menu, press the BACK button to return to the previous menu and save any changes. In all top-level menus, button six is the EXIT button. Pressing EXIT removes the menu system and moves many of the onscreen elements down to their original positions.
Product Operation AUX page in place of the EMS page. Pressing BACK will return you to the main EMS menu, and your original screen configuration (i.e., EMS). If you press the SETUP button on the EMS menu, the SETUP menu is displayed. The SETUP menu contains a menu tab and button labels for CLOCK, VRSION, GLOBAL, SENSOR, FUEL, and BACK. Pressing CLOCK displays options for specifying time format (i.e., standard AM/PM vs. military) and clock adjustment.
4. AVAILABLE PAGES The EMS main pages use various combinations of circular gauges, vertical and horizontal bars, tic marks, and text to display EMS data. Appropriate units of measurement accompany their respective values. Color indicators (green, yellow, and red) are used to denote normal and abnormal operational ranges.
Available Pages EMS Main Page Available in full format This page displays RPM, manifold pressure (MAP), oil temperature, oil pressure, exhaust gas temperature (EGT), cylinder head temperature (CHT), fuel level, fuel pressure and fuel flow. Up to four user-configurable info items may be displayed at the right side of the screen. For information on configuring the function of these info items, see the EMS Operation section on page 7-1. Up to six EGT/CHT channels may be displayed simultaneously.
Available Pages EMS Times/Auxiliary Page Available in 1/2 | 1/2 format This page displays times information on the left half of the screen and user-customizable auxiliary information on the right half of the screen. The times half is divided into three sections: TIME, TIMERS, and ENGINE TIMERS. The TIME section shows the present time (both local and Zulu) and can be displayed in either standard or military time formats.
Available Pages Some info items, when displayed on the Aux Page, have quick commands to be displayed in the AUX menu. This menu is populated with commands in the order that the items appear on screen (from top left to bottom right). The commands are listed below.
Available Pages Some user input is required for the EMS-D10 Fuel Computer to function properly. Refer to EMS Operation on page 7-1 for instructions on adjusting various Fuel Computer parameters. WARNING: The Fuel Remaining, Time Remaining, Distance per Fuel Unit, Fuel Remaining at Waypoint, and the Calculated Range Remaining values are not directly measured. These values are calculated based upon measured flow rates and user input of fuel quantity. Do not use these values as primary indicators.
Available Pages Menu Pages Available in full format Some setup menus require a full page to display all the available options. Menu Pages use a caret symbol (“>”) to indicate the currently selected line. Use the DOWN▼ and UP▲ buttons to scroll through the list of options. Any line on a Menu Page that is followed by ► has more options to configure inside of it. Press SEL► to expand the menu into another list of options to the right.
5. ALERTS Alarm Indicators Any time a built-in or preconfigured alarm set point is exceeded, you are alerted via both visible and audible (if connected) alarms. When an alarm is triggered, the following things occur: The measurement’s value and tick color are highlighted red The measurement’s value and tick blink A red alarm bar appears at the bottom of the screen with a message identifying the out of range measurement Below the alarm bar, the alarm menu gives you options for what to do next.
Alerts “THIS.” Alert messages sourced from another Dynon product are preceded by the label “DSAB.” Pressing SILNCE or ACK on any unit in the system silences or confirms the alarm on all units in the system. See the EMS-D10 Installation Guide for more information. If installed, either the HS34 or AP74 (but not both) can be configured to output EMS, EFIS, and AOA alarm information with tones (such as with direct audio connections to the EMS and EFIS), or via spoken voice alerts.
Alerts Removes the alarm bar and alarm menu (if no other alarms are stacked up), and brings up the previous menu. Stops the blinking of the relevant display Returns the display to the screen configuration displayed before the alarm occurred (if you pressed SHOW [PAGE]) The tic and numeric value remain highlighted red until the condition no longer exists. The alarm automatically rearms whenever the alarm condition is removed.
Alerts Latching and Self-clearing Alarms Depending upon how your EMS-D10 was set up, some of the sensors’ alarms may be set to be latching, while others may be self-clearing. The distinction is described below. See the EMS-D10 Installation Guide for more information on configuring this setting for each alarm. LATCHING ALARMS If an alarm occurs on a sensor configured to be latching, the alert displays on screen until the ACK button is pressed, even if the alarm condition goes away.
Alerts If this error is unexpected, check all Dynon equipment for proper function, and cycle the power to all units. Additional information on the missing unit can be found on the network status page under SETUP > DSAB > STATUS. If a unit is purposefully removed from the system, refer to the EMS-D10 Installation Guide for instructions on reconfiguring the network. NETWORK CONNECTION LOST: This error means that all network communication has stopped.
6. EMS MONITORING This section describes just a few of the ways to use your EMS-D10 to monitor the operation of your engine. Engine Leaning and Power The engine monitor provides multiple methods to assist you in setting the mixture of your engine for various functions. The first, and most basic, is to just watch the EGT display as the engine is richened or leaned. You can watch for the EGTs to peak and then richen or lean as desired from that point.
EMS Monitoring To exit the Lean mode, reactivate the main menu and press the LEAN button; the EGT/CHT display then returns to its normal state. For best results, lean carefully by making small adjustments and allowing some time for temperatures to stabilize before leaning further. In addition to the EGT temperatures, you can also watch the fuel flow rate and CHT temperatures. Carefully read and follow your engine manufacturer’s leaning recommendations for best performance.
EMS Monitoring and EMS units, a “SNAPSHOT” log is also recorded and can be downloaded. The snapshot log records the value of all parameters anytime an alert occurs. INTERNAL LOGGING To activate internal data logging, enter the EMS > SETUP > GLOBAL > DATALOG CONFIG menu and set RECORDING to ON. Set the INTERVAL depending on how frequently you wish data to be stored. Data can be stored at intervals of 1, 3, 5, 10, 30, and 60 seconds.
EMS Monitoring EXTERNAL LOGGING During normal operations, the EMS-D10 constantly streams EMS engine data via the EMS DB37 serial output. To record and/or display data generated by the EMS-D10 in real-time a laptop (or other serial data collection device) must be connected to the serial port(s) of the EMS-D10. The data format and connection settings are described on page 8-2.
7. EMS OPERATION This section contains common step-by-step procedures that are performed before, during, and after flight. You are encouraged to be familiar with all of these procedures prior to flying to ensure readiness as well as maximizing use of the capabilities of the instrument. We recommend that you review and understand the Product Operation section on page 3-1 before reading this section. ON/OFF Turn ON: Press and hold button one. Turn OFF: Exit all menus and press and hold button one.
EMS Operation the system, you must press BRITR on any bright screen unit to get the bright screen units to their final step of brightness. The HS34 and AP74 have a built-in light sensor which can be used to automatically dim all of the screens connected to a DSAB network. To turn this function on, press AUTODIM. When you enable auto-dim, the screen does not immediately change brightness. Instead, the system records the unit’s current brightness level as the desired brightness.
EMS Operation You may configure the PRESET value using the following path: EMS > SETUP > FUEL > PRESET VALUE > INC+/DEC- > BACK. Reset fuel level to full: EMS > SETUP > FUEL > FULL You may configure the FULL value using the following path: EMS > SETUP > FUEL > FULL VALUE > SEL► > INC+/DEC- > BACK. Note: It is necessary to calibrate the EMS Fuel Computer with the sensors for fuel level to work correctly. See the EMSD10 Installation Guide for more details.
EMS Operation minutes are adjusted. When connected to a GPS which is outputting time information, Zulu time is synchronized to the GPS and cannot be set on the EMS-D10. In a DSAB network, you can only set the Zulu time on the DSAB master, and only if it is not synchronized to GPS time. You can set the local time on all units individually. Set 12/24 Display: EMS > SETUP > CLOCK > FORMAT Press the 12/24 button to toggle between STNDRD (12 hour AM/PM format) and MILTRY (24 hour military format).
EMS Operation Global Configuration Settings Configure global settings: EMS >SETUP > GLOBAL The Global page is divided into three sections: PILOT SETUP, SCREEN SETUP, INSTALL SETUP, and LOCAL SERIAL PORT. Pilot settings and screen settings are addressed in this guide. If you or your installer have completed the procedures outlined in the EMS-D10 Installation Guide, you do not need to modify anything in the other sections. Scroll between settings by using the UP▲/ DOWN▼ buttons.
EMS Operation Change power on alarms status: EMS > SETUP > GLOBAL > ALARM CONFIG > PWR ON ALARMS Set this parameter to “ON” to enable alarms before engine startup. When set to “OFF”, all alarms are suppressed whenever ALL of the following conditions exist: RPM less than 400 Oil pressure less than 20 PSI First five minutes after master instrument power applied All alarms are enabled when any of the above conditions are exceeded.
EMS Operation through 8 in the same fashion The Info Items Config submenu appears, allowing you to move up and down the list, selecting which parameter you would like displayed at each info item position. To change the function that a given item displays, press UP▲ or DOWN▼ until it is selected (the > symbol is to its left), and press SEL► to cycle through the available functions. Repeat this for each info item you’d like displayed.
