STARTS/HOUR TRIP
LOCKOUT TIME = XXX MIN.
Total number of motor starts over
the past hour greater than
Number of Starts / Hour setpoint.
Reduce number of starts during
normal motor operation.

ACCEL. TIME TRIP
Motor did not enter a normal
running state (i.e. phase current <
FLC) within Acceleration Time
setpoint.
Excessive load or locked rotor on
start.
