NEW Series EMC48S50-03
Three-Phase Induction Motor Softstarter
200–480 Vac, 11kW (Y), 19kW (D)
INDUCTION MOTOR SOLID-STATE REDUCED VOLTAGE STARTER
(SOFTSTARTER) WITH SOFTSTOP FEATURE
The Series EMC can be used as an alternative to costly and relatively big variable
speed controllers in applications such as pumps, fans, compressors and
conveyors.
Its six-thyristor structure, working like a full-wave phase angle controller (both
positive and negative cycles are controlled), reduces the induction motor starting
current as well as the motor starting torque. The reduction in motor starting
current improves the efficiency of the power used. It also avoids voltage
fluctuations that lead to ambient light variations or “flicker.”
The Series EMC fits existing applications without any modification of the wiring
field configuration. Thus it can replace an electromechanical star-delta starter
without changing the motor coupling. The EMC may be implemented like a
standard three-phase electromechanical contactor for induction motors.
Furthermore, its ability to be installed inside the delta wiring allows the Series
EMC to drive 1.73 times more current than a standard online softstarter.
The Series EMC features diagnostic and self-test functions to assist with machine
maintenance, reduce costs, and delays of restarting equipment.

IMPORTANT INFORMATION ABOUT THE DIAGNOSTIC
1. The device makes a complete diagnostic (mains, load and itself) since it has enough supply voltage (On the mains or on the control side).
2. 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.
3. 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.
4. On a hard stop (no softstop) and in the case of driving a large motor, the device may temporarily 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 remaining magnetic field inside the motor. This also avoids overvoltage across the solid-state switches
(increasing the lifetime expectancy of the integrated varistors). Therefore, softstop is recommended even with high inertia motor loads.

The conducted or radiated disturbances generated by solidstate relays depend on the wiring and load configuration.
The test method recommended by the European standards
concerning electromagnetic compatibility leads to results far from reality.
We recommend use of filters based on your application.
The European standard EN60947-4-2 requires the
measurement to be done at full on state (end of the softstarting period).
Therefore, our products are below the industrial field required levels on
inductive load like the induction motor and no additional filter is needed.
The starting period that may last several minutes generates enough
interference to disturb sensitive devices located near the softstarter.

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 with the
circuit disconnected from the electric grid by an electromechanical
mean insuring a sufficient galvanic isolation.
The EMC 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 mean with sufficient current breaking possibility.
In order to operate the circuit safely, the control part of the
softstarter will have to be disconnected from the control or auxiliary
supplies as well.
ATTENTION
1. The EMC does not correctly operate on three-phase mains with the motor neutral connected to the neutral of the mains. If you have
such a requirement, please contact us.
2. The overload relay must be adapted to the motor.
3. Please take care not to make short circuits while installing the bypass contactor or the backward wires for delta wiring.
4. In case of devices planned to be used connected to a bypass contactor, the control voltage will have to be held sufficiently to allow the bypass
to close. Verify the bypass checking option “byp.”
5. 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.

ADVICE FOR THE SETTINGS
ATTENTION
Obtaining a particular starting time value is only a consequence of the motor torque reduction and cannot 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 EMC 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 EMC cannot 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 stopped slowly (conveyors, ...). In the case of a 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.
