Type S701, Soft Start Controllers with Auxiliary Contact
Type S701, Soft Start Controllers with Auxiliary Contact
Product Description
The S701 device is a reduced
voltage soft start controller
designed to control
acceleration and deceleration
of three-phase motors. With
the auxiliary contact, it is
possible to control an external
bypass to reduce heating and
increase acceleration and
deceleration times.
The unit provides the user
with the ability to adjust initial
torque, ramp up and down
time and also select kick start
for high inertia loads.
Application Description
The S701 line of soft start
controllers is specifically
designed to be a low cost
option for soft starting small
(15 hp and down) three-phase
motors. The auxiliary contact
is designed to work in
conjunction with an across-
the-line contactor. The
purpose of the contactor is
to provide a parallel current
path once the soft starter
has brought the motor up to
speed. Once the soft start
controller reaches end of
ramp, the auxiliary contact will
close and send a signal to
close the bypass contactor,
thus providing a low
impedance path for the
current to the motor. The
S701 unit controls current
on two of three motor phases
to control the torque being
applied to the motor, allowing
for smooth starting of a
motor. The S701 is designed
to be used with a manual
motor protector or a full
voltage starter. These
devices provide the necessary
overload protection for the
motor and also provide line
isolation for the motor.
Short-circuit protection can
be provided by fuses or
circuit breakers.
