reduces internal heating
created by the power
dissipation across the
SCRs. The bypass
contactor directly connects
the motor to the line and
improves system efficiency
by reducing internal power
losses
●
Less heat minimizes
enclosure size and cooling
requirements, and
maximizes the life of all
devices in the enclosure
●
LED displays device status
and provides fault
indication
●
Variable ramp times and
voltage control (torque
control) settings provide
unlimited starting
configurations, allowing
for maximum application
flexibility
Reduced Voltage Motor Starters
Solid-State Controllers
●
Soft stop control suits
applications where an
abrupt stop of the load
is not acceptable.
Soft acceleration and
deceleration reduces
wear on belts, gears,
chains, clutches, shafts,
and bearings
●
Minimizes the peak inrush
current’s stress on the
power system
●
Manages peak starting
torque to diminish
mechanical system wear
and damage
●
24 Vdc control module
enhances personnel and
equipment safety
Protective Features
●
There are two auxiliary
relays—
●
●
●
Mains connection—
The mains connection
is monitored for an
open condition and/or
undervoltage
●
Motor connection—
The motor connection
is monitored for an
open condition
●
SCR faults—SCR
performance is monitored
during the ramp cycle for
proper operation
First relay is a TOR relay
which closes when the
TOR is achieved (internal
bypass relays close)
The second relay is a
RUN relay which closes
when the RUN signal is
initiated and opens
when RUN signal is
removed. It remains
closed during stop ramp
time, if set to a value
greater than 0. The RUN
relay will also open if a
fault occurs
●
Heat sink over/under
temperature—High
ambient temperatures,
extended ramp times, and
high duty cycle conditions
may cause the DS6 to
exceed its thermal rating.
When temperature goes
under –5°C, unit will trip as
well. The DS6 is equipped
with sensors that monitor
the temperature of the
device. The soft starter will
trip in over/under
temperature conditions,
preventing device failure
●
Bypass relay—The DS6
can detect if the bypass
relay fails to close after the
ramp start or opens while
the motor is running. The
DS6 will trip on a bypass
dropout fault if either of
these conditions occur. The
device does not start when
bypass relay is closed and
start signal is applied
●
24 Vdc low voltage—
If the control voltage falls
below 20 Vdc at any time
during operation, the unit
will fault
