1.
Stop is 1fter an autcratic start due to a safety injection actuation signal (SIAS)
PCIE: The diesel is turning unlov]ed.
2.
The diesel is runnirg unloaded after a nornal (ncr.-emrgercy) start It is inportant to be aware of the conditions urder which the diesel generator was started, as this can nake a diffe ence as to hcw the diesel m
generator will be shut dcAn.
Spect to perfom a rortal stcp 1ccally if the diesel was started locally.
If the contml toas s'.arted the diesel, it will usually be stcypod frun the conttul roco.
