Symptom Cause
Solution
Prime mover will not
start. Actuator not
moving to start fuel
position (continued).
Speed sensor signal not clearing
failed speed signal circuit.
Check wiring for proper connection. Check
shields for proper installation. Check the
Display Menu for Engine Speed reading.
Speed sensor not spaced properly—check
for at least 1.0 V ac at terminals 25 and 26
during cranking. If less that 1.0 Vac,
magnetic pickup may be spaced too far
from gear. Make sure there are no metal
chips on end of pickup.
If no voltage is present, magnetic pickup
may be open-circuited or shorted. Make
resistance check with the leads
disconnected from control. Should be about
100 to 300
.
Failed speed signal circuit may be disabled
by connecting terminal 28 to terminal 32.
Be prepared to make an emergency
shutdown when starting the engine,
turbine, or other type of prime
mover, to protect against runaway or
overspeed with possible personal
injury, loss of life, or property
damage.
Faulty 2301D control.
Replace.
Prime mover overspeeds
only on starts.
Ramp adjustment.
Increase RAMP TIME. This decreases
acceleration rate (from low idle to rated).
RATED SPEED setting too high.
Check that RATED SPEED is entered as
described in Chapter 4. Verify the Fuel
Demand % drops to minimum (0%) when
engine speed is greater than speed
reference.
Dynamics adjustment.
Dynamics may be adjusted for sluggish
operation, causing overspeed on start.
Adjust GAIN for fastest stable response.
RESET may be adjusted too low. Increase
RESET setting.
Determine if engine is
malfunctioning.
Verify that fuel rack is not binding and
linkage is properly adjusted. Determine if
the fuel rack is quickly following the actuator
input voltage. Check operation of
overspeed protection device(s).
