Soft Start Benefits for Pumps

• Soft Stop
• Timed Voltage Ramp extends and control the pump

  fluid hammer often associated with uncontrolled
  pump stopping.
• This will reduce the need for regular
  maintenance/repair and extend the life of pumps,
  valves, pipes, transducers, etc.
• New installation costs can be reduced because the
  system design need not allow for repetitive high
  pressure surges. For example, pressure surge
  tanks and motorised valves become unneccessary
  and the specification of pipes, valves,
  transducers, etc, can be reduced.

• Minimises torque transients for gentle winch
  starting thus extending coupling, winch line and
  bearing life.
• Related VS i II Functions Current Limit, Current
  Ramp
• Minimum Start Current
• Reduces electrical disturbance on the supply.
• Limits the demand on the supply. This is
  important in marine situations where generator
  sets are used for reticulation.

Soft Start Benefits for Winches

• Motor Overload Protection
• The VS i II allows the maximum time that the
  motor can run at locked rotor current at 600.
• Provides reliable motor protection while allowing
  the winch to ride through temporary overload
  situations.
• Related VS i II Function Motor Trip Class
• Motor Thermistor Protection
• Motor thermistors can be connected directly into
  the VS i II thermistor input.
• This eliminates the need for special control
  equipment to be installed.

Soft Start Benefits for Winches

• Excess Start Time
• If a successful start is not achieved within the
  excess start time setting, the VS i II will trip.
  
• This will prevent damage to the motor caused by a
  jammed or excessively overloaded winch during
  start up.
• Related VS i II Function Excess Start Time
• Instantaneous Overload Protection
• Motor current is monitored and if the level
  detected is higher than that of the instantaneous
  overload protection, the VS i II will immediately
  trip.
• This will prevent damage to the motor, winch line
  and couplings caused by severe overload or a
  stalled winch line.

Soft Start Benefits for Screens

• Gentle Acceleration
• Reduces mechanical stress on couplings bearings
  and other moving parts extending equipment life
  and lowering maintenance costs.
• Related VS i II Functions Current Limit, Current
  Ramp
• Minimum Start Current
• Reduces electrical disturbance on the supply by
  minimising the required start current. This is
  important at remote sites where supply is
  limited.
