LEROY-SOMER D4 Digistart Simple and Compact Soft Starter Instruction Manual

LEROY-SOMER D4 Digistart Simple and Compact Soft Starter

Product Information

The Electronic controllers for fixed speed applications 24 to 1250 A are smart and communicating starters. They are a new generation of starters designed to make life easier for users. These starters are manufactured by Nidec Leroy- Somer and are reliable and robust.

The Digistart soft starter is equipped with a dynamic QR code that can be generated on the display and read by the Nidec Leroy-Somer Digistart app installed on your smartphone. This feature allows easy access to event logs, report preparation, diagnosis, viewing the history of the last 3 faults, and product documentation.

The Digistart starters have various characteristics and advantages. They offer quick setup via the mobile app, simulation mode, automatic timers and date- based operation, power through (operation in degraded mode), emergency mode, USB port, and plug-in terminals. These starters are easy to commission and maintain most control and protection functions. They also allow continuous operation in degraded mode and easy data retrieval without the need for a PC or network.

For specific applications like pumping and irrigation, the Digistart starters offer a smart card that allows direct connection of sensors to the Digistart without the need for additional components.

The Digistart D4 – D5 starters are efficient and powerful. They are designed to achieve energy efficiency right from start-up. These starters are optimized for use with IE3 motors and offer aninternal bypass that optimizes energy consumption and achieves 99.5% efficiency in operation.

When selecting the right controller and motor for your system, consider the following:

• Evaluate output requirements, optimal process set-up, satisfactory equipment operation, etc.
• Consider whether a fixed-speed or variable-speed control mode is suitable for your application. Fixed-speed controllers are generally more efficient than variable-speed drives.
• The Digistart starter range is optimized for use with IE3 motors, which provide the most efficient control mode for a fixed speed and variable load system.

A new generation of starters

The Digistart soft starter has been upgraded and brings fresh features with the new D4 and D5 ranges. The new series are designed to better meet the productivity needs of your fixed-speed equipment, and incorporate the latest control and protection technologies as well as embedded intelligence functions.
The new starters not only start and stop your machines accurately and efficiently, they can also help minimise your energy bill and improve your operational performance by transmitting key data to operators and automatic control systems.
The communication functions of this new series have been significantly improved compared to the previous generation, to allow for the easy adjustment of basic parameters. Thanks to the integrated console, standard USB port and mobile app, Digistart offers immediate and intuitive access to configuration menus for applications such as pumping, ventilation, conveying, compression, crushing, etc.
The D4 model (24–580A) with its ultra-compact design is primarily dedicated to simple applications or redundant electronic drive solutions. The D5 model (24–1620A) incorporates more features, offering one of the most powerful electronic controllers for asynchronous motors on the market. Both models are compatible with all three-phase 200–525 V, 380–600 V or 690 V networks.

Why not make life easier?

Smart does not necessarily mean complex. The new Digistart units offer more functions, but they have been designed to provide a more user-friendly, ergonomic, simpler and richer user experience.
Thanks to an improved display and more intuitive connectivity, it is now easier to access useful information when you need it. Thanks to the new USB port, you can download and store starter performance data, helping you to efficiently manage the system.

Programming and automation functions allow for more customised operations to
meet your facility’s requirements, minimising the need for manual action and ensuring continuous operations.
Digistart also includes starter, motor and system protection functions as well as alarms to prevent breakdowns. If a problem arises, you can continue to operate in degraded mode thanks to the Power Through and Emergency Run functions.

A well designed start-up

Digistart is redefining the role of soft starters with its smart option cards. Several business cards are available and can be used to manage specific applications such as pumping. By using the appropriate card, Digistart can function as a complete system controller.

Business smart cards are easy to integrate, and offer specific functions and Inputs/Outputs designed to meet the needs of a particular industry or application, simplifying design, installation and integration and giving you real control over your fixed-speed equipment.

Smart card for pumping

Installing the pumping card allows the sensors in question to be connected directly to the Digistart. On this basis, there is no need to install additional components, as generally required to provide this level of information and control functions specific to your system.

For cards for other applications, please contact your usual sales contact.

Digistart D4 – D5 Efficient and Powerful

Aim for efficiency right from start-up
When designing energy-efficient systems, the system as a whole must be taken into consideration. Using energy efficient components is important, but selecting the most appropriate motor control mode (fixed or variable speed) is also critical.

The Digistart starter range is optimised for use with IE3 motors. This is the most efficient control mode for a fixed speed and variable load system.

Digistart – Maximum energy efficiency for fixed-speed applications

IE3 compatibility
IE3 motors can be used in order to maximise energy efficiency and save on operating costs, but starting such motors can be more difficult, especially due to:

• higher inrush and start-up currents, which place high demands on the power supply circuits
• “Sawtooth” breakaway torque curves that make smooth control more difficult.

This is not a problem for the Digistart starter, which has been designed to make it easier to control IE3 motors. The Digitstart features a new adaptive control system able to read the characteristics of the motor during the first start/stop and then adjusts control to optimise performance. Simply select the most appropriate profile for the load type and the soft starter will automatically manage the smoothest possible acceleration for the load.

OPT FOR THE INTERNAL BYPASS FOR ADDITIONAL SAVINGS
Digistart has a built-in bypass to optimise energy consumption.
Thanks to this device, energy efficiency and thus energy savings are maximised for fixed-speed applications. This approach significantly reduces operating costs.
In addition, Digistart does not produce harmonics during operation, so no additional filters are required and system losses resulting from harmonics are eliminated. This bypass also reduces heat loss during operation.
Opting for an internal Bypass simplifies the installation process and reduces the overall dimensions of the equipment.

USING ADAPTIVE CONTROL TO OPTIMISE PERFORMANCE
Digistart offers 4 control modes to cover all requirements:

• Timed voltage ramp for applications with low inertial loads
• Constant current/current ramp for applications with variable loads such as conveyor belts
• Torque control for applications requiring a linear start-up and shutdown, such as ski lifts
• Adaptive control for all types of applications
