SMB™ Smart Motor Braking Option
Accu-Stop™ and Slow Speed with Braking
Fast Acting Current-limiting Fuses
ATTENTION: Pump stopping is not intended to be used as an
emergency stop. Refer to the applicable standard for emergency stop
requirements.
ATTENTION: Pump stopping may cause motor heating depending on
the mechanical dynamics of the pumping system. Therefore, select the
lowest stopping time setting that will satisfactorily stop the pump.
ATTENTION: Slow speed running is not intended for continuous
operation due to reduced motor cooling.
ATTENTION: SMB Smart Motor Braking is not intended to be used as
an emergency stop. Refer to applicable standards for emergency stop
requirements.
ATTENTION: Accu-Stop and Slow Speed with Braking are not
intended to be used as an emergency stop. Refer to applicable
standards for emergency stop requirements.
ATTENTION: The fast acting current-limiting fuses specified in Table
2.C of the user manual may not provide branch circuit protection.
Branch circuit protection in accordance with applicable electrical codes
may require additional fusing (or a circuit breaker) even though fast
acting current-limiting fuses are used.
ATTENTION: Applications requiring extended acceleration times or
high duty cycles may experience nuisance tripping of the coordinated
fast acting current-limiting fuses. This type of fuse has a limited
thermal capacity that is less than that of the SCRs they are designed to
protect. This makes them susceptible to thermal fatigue.
