SV-EMS-220 Installation and ConfigurationHorsepower is used to do some of the % power calculations and the auto Rich-of-Peak andLean-of-Peak detection. Set it to the engine manufacturer's rated HP for initial usage. You mayneed to adjust this number in order to get all calculations working correctly.If you are getting an auto Lean-of-Peak indication that is coming on too early, before the engineactually peaks while leaning, lower this number. It is not meant to be a measure of actualhorsepower produced, as engines that are more efficient will act as if they are lowerhorsepower in the calculation. This will be particularly true if you are running a highercompression ratio than the stock charts are based upon.Cruise RPM is used when calculating tach time. Tach time is a measure of engine timenormalized to a cruise RPM. If you spend one hour at your cruise RPM, tach time will incrementone hour. If you spend 1 hour at 1/2 your cruise RPM, tach time will only increase by 1/2 hour.Tach time is defined as TIME x (CURRENT RPM / CRUISE RPM).Hobbs time is a simple timer that runs whenever the oil pressure is above 15 PSI or the engineis above 0 RPM.If you have connected an External Alarm Light to SV-EMS-220 pin 29, the Alarm Light settingdetermines how the light behaves after alarm acknowledgement. It can be set to either SOLIIDAFTER ACK, which leaves the light lit continuously after acknowledgement (until the alarmcondition ceases) or OFF AFTER ACK, which turns the light off after an alarm has beenacknowledged.EMS Sensor Definitions, Mapping, and SettingsAll sensors must be defined, mapped to SV-EMS-220 pins, and have their settingsconfigured. This section describes how sensors are defined, mapped, and set inSkyView.EMS Sensor DefinitionAll EMS sensor installations require a SkyView Sensor Definitions file. This file is preloaded ontoeach display prior to shipment and contains all of the sensor types that SkyView supports. Itmay be updated in the future to include more sensors. This file is downloadable atdownloads.dynonavionics.com.If you need to update the SkyView Sensor Definitions file, download the file and use theinstructions found in the How to Load and Delete Files Section.The EMS sensor definition file has a .sfg file extension. This file is not automaticallyshared between displays. It must be loaded onto each display in the system.7-42 SkyView System Installation Guide - Revision J
