Schneider Electric soft starter series Altistart 48 for asynchronous motors.

The Altistart 48 soft start/soft stop unit is a controller with 6 thyristors used for torque-controlled soft starting and stopping of three-phase squirrel cage asynchronous motors, for power ratings between 4 and 900 kW. It offers soft starting and deceleration functions along with machine and motor protection functions, as well as functions for communicating with control systems.

These functions are designed for use in the most common applications for centrifugal machines, pumps, fans, compressors and conveyors, which are primarily to be found in the construction, food and beverage and chemical industries. The high-performance algorithms of the Altistart 48 contribute significantly to its ruggedness, safety and ease of setup.

The Altistart 48 soft start/soft stop unit is a cost-effective solution which can: b reduce machine operating costs by reducing mechanical stress and improving machine availability, b reduce the stress on the electrical distribution system by reducing line current peaks and voltage drops during motor starts.

The Altistart 48 soft start/soft stop unit offer comprises 2 ranges:
- three-phase voltages 230 V to 415 V, 50/60 Hz,
- three-phase voltages 208 V to 690 V, 50/60 Hz.
In each voltage range, the Altistart 48 soft start/soft stop units are sized for standard and severe applications.

Special uses for Schneider Electric soft starter series Altistart 48.

In addition to the most frequently encountered wiring layouts, where the starter is installed in the line supply of the motor and the motor is connected in star or delta configuration, the Altistart 48 ATS48...Q can be wired to the motor delta terminals in series with each winding (see figure below). The starter current is lower by a ratio of 3 than the line current absorbed by the motor. This type of installation enables a starter with a lower rating to be used.

This type of installation only permits freewheel stopping and is not compatible with the cascade and preheating functions.

Special uses for Schneider Electric soft starter series Altistart 48.

Note: The nominal current and limiting current settings as well as the current displayed during operation are on-line values (so do not have to be calculated by the user).

Starter bypassed by a contactor.
The starter can be bypassed by a contactor at the end of starting (to limit the heat dissipated by the starter). The bypass contactor is controlled by the starter, and the current measurements and protective mechanisms remain active when the starter is bypassed. The starter is selected on the basis of the 3 main criteria and one of the following criteria:
- If the starter is bypassed at the end of starting, the motor is always started from cold state and the starter can be oversized by one rating.
Example: Select an ATS 48D17Q for an 11 kW motor in a standard 400 V application. - If the starter needs to be able to operate without the bypass contactor at the end of starting, it does not have to be derated.
Example: Select an ATS 48D17Q for a 7.5 kW motor in a standard 400 V application.

Schneider Electric soft starter series Altistart 48 remote terminal.

The terminal can be mounted on the door of a wall-fixing or floor-standing enclosure. It has the same signaling display and configuration buttons as the terminal integrated in the starter. A menu access locking switch is located on the rear of the terminal.

The option comprises:
- the remote terminal,
- a mounting kit containing a cover, screws and an IP 54 seal on the front panel,
- a connection cable 3 m/9.84 ft long, with a 9-way SUB-D connector at the terminal end and an RJ45 connector at the Altistart 48 end.
