LAT Timer Large motors with a high inertia may experience starting
currents that exceed the locked rotor current and time.
The protective relay has logic and provisions for a zero
speed switch input to differentiate between a stall and
start condition. If the motor is spinning then the relay will
not trip on the normal locked rotor time allowing the
motor to start.

ABK Fc For certain applications, such as pumping a fluid up a
pipe, the motor may be driven backward for a period of
time after it stops. The protective relay provides an anti-
backspin timer to prevent starting the motor while it is
spinning in the reverse direction. The timer begins
counting from the moment a stop is declared by the relay.
