The Display Communications Status LED indicates the display is properly communicating with
the controller (green). If communications are interrupted, this LED will turn red. During
initialization, this LED will be red until the communication test passes near the end of the
initialization. Then it will turn green, and the message “Initialization Complete” will appear for a
few seconds indicating everything is ready to go.
Engine Start Up.
When ready to start the engine, the user can press the Operator Page button and monitor the
start up on the Operator Page. Figure 2.0 shows the Operator Page.
Figure 2.0 Operator Page
Figure 2.0 shows the page contents when the system is in the standby mode and is ready to
start the engine. In this example, the timing schedule A is active, and the timing is set for 10.0
degrees (BTDC). The Tank voltage is 239.3, and the energy level is 78%. The Alarm and
Shutdown relays are off indicating no alarms pending and no prior shutdowns. It also shows
that Ignition Enable is enabled meaning the U-lead is not grounded and Ignition Enable input is
open circuited.
As the engine starts to crank, the display will show the PIPs counted. If the PIPs are within
specification, the Ign On Rly LED will turn green indicating the actual relay has activated. This
also means the coil output drivers have started to fire. If the primary harness is connected the
coils will be firing the plugs. If the primary harness is not connected, the user would see all
“Open Primary” on the Spark Page.
