ENGINE STARTS TO RUN: NO FAULTS
When the engine starts to run, the speed will increase to the
speed setting of the ESS crank terminate function, and the ESS(CT)
switch across terminals ESS- I and ESS-12 will open. The current
flow is now stopped to the start pushbutton for the starter motor(s) as
shown in Fig. 3.
When the ESS(CT) switch (line 10) opens across terminals ESS-
11 and ESS-12, ESS(CT) switch (line 32) will close across terminals
ESS-11 and ESS-10. This closed switch will give current flow to
Control 1 (terminal 1) of time delay relay (TDI), and will immediately
close switch (TDI) across terminals TD1-6 and TDI-7 (line 25). The
complete protection system is now armed to activate an alarm or
cause engine shutdown if there is a fault in any of the three engine
systems now being monitored.
