Technical Data and Specifications
Reduced Voltage Starters
Operation
Overload Functionality
Overtemperature
Protects the device from
overheating. Starter will
shut down at 100°C.
Stall
Selectable protective feature,
unit trips to protect system in
event motor can not get to
rated speed in the defined
ramp period.
Jam
Selectable protective feature,
unit trips to prevent damage
to motor during normal run.
Phase Loss
Selectable protective feature,
trips under voltage loss
condition to any phase.
Phase Reversal
Selectable protective feature,
trips when phase rotation is
something other than A-B-C.
Kick Start
Selectable feature that
provides a current “kick”
of up to 550% of full load
current for 0 to 2.0 seconds.
This provides the additional
torque required at startup to
break free a motor.
Ramp Start
Provides a constant increase
in torque to the motor.
Current Limit Start
Limits the maximum current
available to the motor during
the startup phase.
Soft Stop
Allows for a controlled
stopping of a frictional load.
Shorted SCR Detection
Monitors for shorted SCR
in the power poles.
Starting Characteristics
Kick Start
Provides an initial boost of
current to the motor to help
overcome motor inertia and
begin motor rotation.
●
0–85% of locked rotor
torque
●
0–2.0 seconds duration
Starting Characteristics—Kick Start
Ramp Start
The most commonly used
form of soft start. This allows
you to set the initial torque
value (of the ramp) and then
raises it to full voltage
conditions.
●
Adjustable initial torque =
0–85% of locked
rotor torque
●
Adjustable ramp time =
0.5–180 seconds
