remains on, even if the switch resets, until the igni-
tion input X1/1 (15) is recycled.
8. The monitoring system will shut the engine down
(ouput to X1/7 is cut) if one of the following fault
input signals is present for 3 seconds:
a. No frequency on W - X2/10
b. Input on Oil - X2/1
c. Input on Temp - X2/3
9. When there is a 24V output on X2/9 (50f), the engine
speed is increased by energizing the throttle sole-
noid. The circuit card generates this output from a
24V input on X1/3 (Aux2).
