Symptom Cause
Solution
Prime mover does not
decelerate when Close
for Rated contact is
open.
Faulty Close for Rated contact.
Check Close for Rated contact. Remove
wire from terminal 32. Prime mover should
decelerate.
LOW IDLE SPEED set the same
as rated
Check the Speed Settings Menu.
Generator Aux contact is closed.
A faulty Close for Rated contact may
remain in the accelerate position with the
contact open.
In general, adjustment of LOW IDLE
SPEED will vary the speed of the prime
mover with the Close for Rated contact in
the decelerate (open) position. Adjustment
of LOW IDLE SPEED should not affect
prime mover speed when the Close for
Rated contact is closed.
Prime mover will not
stabilize at rated no load
speed. The instability
may occur at no load or it
may vary with load.
Control may be erratic.
2301D control.
Adjust GAIN, RESET, and ACTUATOR
COMPENSATION as described in “Adjust
for Stable Operation” and “Dynamic
Adjustment” in Chapter 4.
Speed reference controls.
Check display menu. The speed reference
value should be constant. If speed
reference is erratic, check remote input (if
used), intermittent raise/lower contact
inputs. The speed bias sum at no load
should be constant.
Improper linkage adjustment.
Make sure that actuator moves
approximately 2/3 of its travel from no load
to full load. Be sure linkage is linear on
turbine, diesel, and fuel-injected prime
movers. Be sure linkage is non-linear on
carbureted prime movers. Refer to actuator
manual for proper installation.
