Relay Outputs
• Fixed Output Relay (13-14)
– designed to control a line contactor
– relay is closed while the soft starter is starting,
running or stopping the motor
![Page 18: LV Compact Soft starter Familiarisation Presentation - SSUK](https://reader030.vdocuments.us/reader030/viewer/2022020123/55acf12a1a28ab44798b4690/html5/thumbnails/18.jpg)
Relay Outputs
• Programmable Output Relay (23-24)
• Is designed to provide a N/O contact which reports the soft starter
status , it can be configured to indicate a trip or run (operating in
bypass) .
• Trip Output
– operates when the soft starter trips
– use to operate a shunt trip of an upstream Circuit Breaker or
signal the trip status to an automation system

Adjustments
• Eight adjustments can be made on the LV-AS soft starters:
– Current Limit
– Current Ramp
– Stop Ramp Time
– Motor FLC
– Motor Trip Class
– Excess Start Time
– Phase Sequence Protection
– Auxiliary Relay Function
![Page 25: LV Compact Soft starter Familiarisation Presentation - SSUK](https://reader030.vdocuments.us/reader030/viewer/2022020123/55acf12a1a28ab44798b4690/html5/thumbnails/25.jpg)
LV-AS Setup
• Motor FLC –
– All motor protections are based on this
setting.
– The minimum “Motor FLC” setting is 50%
of the LV-AS nameplate rating. Range
50-100%
Example – LV-AS-018 18A
If the motor FLC on the motor nameplate = 15A
The motor FLC (% soft starter FLC) = Motor
FLC ÷ LV-AS FLC
15A FLC ÷ 18A LV-AS FLC = .83 or 83%

Constant Current
• Ideal where start current must be kept
below a particular level.
• Current is passed at the selected level
until the motor has accelerated.

• Current Limit – (%FLC) Factory setting
350%. It provides the maximum start current
from 250 – 475% FLC covering all types of
general applications.
• 60% of motor applications are for centrifugal
pumps.
• These have quadratic load characteristics
measured as TN2 (torque is proportional to
speed squared)

Current Ramp• Current rises from a specified starting level to a
maximum limit, over an extended period of time.
• Useful for applications where:
– the load can vary between starts
– the load breaks away easily, but starting time
needs to be extended
– the electricity supply is limited (eg generator
sets)
![Page 29: LV Compact Soft starter Familiarisation Presentation - SSUK](https://reader030.vdocuments.us/reader030/viewer/2022020123/55acf12a1a28ab44798b4690/html5/thumbnails/29.jpg)

• Current Ramp – (% FLC/Ramp Time)
Factory setting = Off
• The LV-AS offers current ramp soft starting.
During a current ramp soft start , the LV-AS
raises the current to an initial level, then
increases the current to the current limit , over a
user defined period (up to 15 seconds)
LV-AS Setup
![Page 31: LV Compact Soft starter Familiarisation Presentation - SSUK](https://reader030.vdocuments.us/reader030/viewer/2022020123/55acf12a1a28ab44798b4690/html5/thumbnails/31.jpg)
Stop Methods
• Soft starters help eliminate the damaging
effects of fluid hammer.
Stop Method Performance Effect
Coast to stop Natural load run down
Timed voltage ramp Extended run down time
![Page 32: LV Compact Soft starter Familiarisation Presentation - SSUK](https://reader030.vdocuments.us/reader030/viewer/2022020123/55acf12a1a28ab44798b4690/html5/thumbnails/32.jpg)
Timed Voltage Ramp
• Reduces voltage to the motor gradually over a
defined time.
• Load may continue to run after the stop ramp is
complete.
• Useful for applications where the stop time
needs to be extended, or to avoid transients on
generator set supplies.
![Page 33: LV Compact Soft starter Familiarisation Presentation - SSUK](https://reader030.vdocuments.us/reader030/viewer/2022020123/55acf12a1a28ab44798b4690/html5/thumbnails/33.jpg)

• Soft Stop – Factory setting – No soft stop
• The LV-AS offers a timed voltage ramp soft stop.
The soft starter reduces its output voltage over a
specified period (0 to 20 Seconds) , adding
inertia to the load and allowing the motor to slow
down gradually
• Coast to Stop
• A setting of 0 seconds removes voltage
immediately allowing the motor to coast to
stop

• Motor Trip Class – Class 10 general setting
• Excess Start Time – Factory setting = 10
( used in case the motor stalls or a characteristic
has changed)
• Added backup – even when the excess start time
is set to off it automatically defaults to 120 seconds
• Phase Sequence/Aux Relay Set
• (Example Can tell a PLC if the LV-AS trips)
• Any rotary switch settings adjusted during run
will only take effect on the next start.

Balanced Vector Control
• Two phase control with the waveform
symmetry of three phase control.

• A superior control algorithm that minimises
the imbalance between the controlled and
uncontrolled phases.
• Balanced vector control gives:
– more uniform motor acceleration torque
– more evenly balanced phase currents
– lower noise & vibrations
