SV-EMS-220/221 Installation and Configurationpower. Connect the other lead to pin 29 on the SV-EMS-200 37-pin wiring harness. During analarm condition, this pin is connected to ground, causing current to flow through the lamp.Aircraft Spruce P/N 17-410 is an example of a light that will work for this application. An LEDand resistor in series will also suffice. If you use an LED as the indicator, you must choose aresistor that delivers the appropriate current to the LED, and can accommodate the powerrequired for its current and voltage drop. Also note that the power and ground connections onLEDs are not reversible.Engine InformationUse the Engine Information Wizard (SETUP MENU > EMS SETUP > ENGINE INFORMATION) tospecify the engine type, its horsepower rating, its redline and cruise RPM, the RPM pulseconfiguration, and tach and Hobbs time (if installation is in a non-zero time engine).The Inhibit Engine Alerts at Boot option: When set to YES, all engine alerts, both audio andvisual, will occurs until after the first engine start, or 5 minutes, whichever comes first. Thisoption can help inhibit nuisance alarms before the engine is started. When set to NO, enginealerts are always active.If you have an engine type that is in the list, please choose the appropriate engine. This willallow the system to perform some calculations that are specific to that engine, such as % power(Lycoming / Continental only) and special operating limitations (Rotax only). If your engine isnot listed, choose "Other."Horsepower is used to do some of the % power calculations (Lycoming/Continental enginesonly) and the auto Rich-of-Peak and Lean-of-Peak detection. Set it to the engine manufacturer'srated HP for initial usage. You may need to adjust this number in order to get all calculationsworking 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-220/221 pin 29, the Alarm Lightsetting determines how the light behaves after alarm acknowledgement. It can be set to eitherSOLIID AFTER ACK, which leaves the light lit continuously after acknowledgement (until thealarm condition ceases) or OFF AFTER ACK, which turns the light off after an alarm has beenacknowledged.7-52 SkyView System Installation Guide - Revision O
