ACTUATOR GP-PUMP 2052437 - Caterpillar

Start-up
The CAESultra system on the machine powers up when the machine's key start switch is turned to the ON position. The computer system runs through a number of self-diagnostic tests prior to running the CAESultra application. The following steps outline the sequence of events for start-up:
BIOS Power On Self Test (POST)
Start the operating system.
Start the CAESultra program that is called (CAESCTRL).Note: Once power has been applied to the CAESultra system, the power should not be interrupted until the CAESultra program is running. While the system is starting up, cutting off the power may result in a corruption.The program begins a five minute countdown before the application is started. During this countdown, the machine's engine can be started or power can be turned off without damaging the system. The countdown protects the system from voltage drops during cranking.The CAESultra Start-up screen is shown in Illustration 1.

Start-up screenCAESultra will automatically start after the five minute countdown is completed. If CAESultra starts before the engine, cycle the power in order to have the machine's engine start during the "Countdown" period.Shutdown
CAESultra will shut down in response to turning the keyswitch to the OFF position. The application will require a few seconds to complete all pending actions. During this time, the system's power must be maintained. Once CAESultra has completely shut down, the screen will go dark.Note: Do not turn off the isolator until the D3:C4 Nav 10.4 Display has completed the "shut down" process and the screen has gone dark.
