EMS Configuration
When you modify one value, it will not “push” another value up or down. So, in the example
above, you would not be able to increment the HI YEL/GRN parameter beyond 95 until you
increased the HI RED/YEL parameter. Likewise, you would not be able decrement the HI
RED/YEL value below 90 until you decrease the HI YEL/GRN parameter.
To disable alarms before engine start, enter the EMS > SETUP > GLOBAL > ALARM CONFIG
menu. Set PWR ON ALARMS to OFF. With this parameter set to “OFF”, all alarms are

First five minutes after master instrument power applied
All alarms are initialized when any of the above conditions are exceeded.
