INDUCTION MOTOR SOLID-STATE REDUCED
VOLTAGE STARTER (SOFTSTARTER) WITH
SOFTSTOP FEATURE (PRELIMINARY DATA)
SMCW6080
celduc relais SMCV can be employed everywhere using a costly and relatively big
variable speed controller is not required (pumps, fans, compressors, conveyors, …).
Its six thyristor structure working like a full wave phase angle controller (both positive
and negative cycles are controlled), allows to reduce efficiently the induction motor starting current
as well as the motor starting torque. This motor starting current reduction allows to optimize
the mains grid as well as its protections and avoid having voltage fluctuations leading to
ambient light variations also called "flicker".
Built to help the user to get his assembly in compliance with the European directives and
standards, this product easy fits in the existing application without any modification of the wiring
field configuration. Thus, the SMCV can easily replace an electromechanical star-delta starter
without changing the motor coupling! In a project including a three phase induction motor it can be
implemented like a usual three phase electromechanical contactor. Furthermore, its ability to be
installed inside the delta wiring allows this device to drive 1.73 times more current than a
standard on line softstarter,
The SMCV also have diagnostic and self-test functions to inform people involved in the
machine maintenance and to reduce the cost and the delay to restart the production.

IMPORTANT INFORMATION ABOUT THE DIAGNOSTIC
123-
4-
The device makes a complete diagnostic (mains, load and itself) since it has enough supply voltage (On the mains or on the control side).
The device only checks the presence of the phases and the closing of the solid state switches during the voltage ramps (Softstart and
softstop) and during the full on state period.
The control overrides the diagnostic.
If a problem occurs during the control period, the device will close all the solid state switches. If the problem goes on during
the full on state period, the corresponding information will be given to the user according to the table above.
Likewise, if a problem occurs during the softstopping period, the device will stop immediately in order to reach the off state
diagnostic period.
On a hard stop (no softstop) and case of driving a large motor, the device may temporary display a problem concerning the mains. This is
due to an important residual voltage across the motor windings (Back EMF generated by the motor rotation and the remaining magnetic
field). This security allows the user to avoid connecting the motor to the mains in bad conditions. This phenomenon can be cancelled by
using the softstop feature that slowly reduces the remanent magnetic field inside the motor. This allows as well to avoid overvoltage
across the solid state switches (increasing the lifetime expectancy of the integrated varistors). Therefore, softstop is recommended even
with high inertia motor loads.

INSTALLATION
IMPORTANT
DANGER!
The installation of this product must be done by qualified people,
informed about electric hazards (electrocution risks linked to the
voltage levels in the circuit).
Any intervention on the installation must be operated the circuit
disconnected from the electric grid by an electromechanical mean
insuring a sufficient galvanic isolation.
The device concerned by this document is composed of silicon
based solid state switches. They never ensure a safe function when they
are not controlled (Important leakage current and untimely closing).
Therefore, we advise you to use an electromechanical device in series
with the softstarter, which can ensure a safe operation in the
disconnected circuit.
The emergency stop must not be done by the softstarter. It must
be done by an electromechanical with sufficient current breaking
possibility.
In order to operate in the circuit in safe condition, the control
part of the softstarter will have to be disconnected from the control or
auxiliary supplies as well.
ATTENTION
1-
The SMCV does not correctly operate on three phase mains with the motor neutral
connected to the neutral of the mains. If any, please contact us.

The overload relay must be adapted to the motor.
Please take care not to make short-circuits while installing the by-pass contactor or the backward wires for delta
wiring.
In case of devices planned to be used connected to a by-pass contactor (SMCW…1 reference), the control voltage will
have to be held sufficiently to allow the by-pass to close. Take care not to remove the by-pass checking option "byp.".
In case of fast softstarting and softstopping controls without waiting for the end of the ramps, the motor may heat up.
Please contact your motor supplier to choose an adapted model.

ADVISES FOR THE SETTINGS
ATTENTION
Obtaining a particular starting time value is only a consequence of the motor torque reduction and can not be
guaranteed or easily repeatable. The rotary switch « Time (s) » setting values only give the duration of the voltage ramp
applied to the motor but not necessarily its starting time. The main SMCV function is to obtain a motor torque reduction to
take care of the motor load and the electric grid. The motor starting time is only a consequence and completely depends on
the motor itself, its load and the settings done by the user.
The SMCV can not break a motor driving a load that has much inertia. The user can only obtain a stop time equal
or longer than a simple disconnection from the electric grid. Using the softstop feature can only be justified when the motor
load tends to break the motor (pumps, …) or when the products treated by the machine need to be stop slowly
(conveyors,…). In the case of load with high inertia, the softstop feature can help to reduce slowly the magnetic field inside
the motor to avoid long time overvoltage in the circuit.
