ATS22C32Q

What type of device is this?

It is an Altistart 22 soft starter designed to manage the starting and stopping of three-phase asynchronous motors. It progressively controls motor torque to reduce mechanical stress and high starting currents.

Which motor applications is this soft starter suited to?

The unit is primarily intended for pumps and fans, although it may also be suitable for other compatible asynchronous motor applications following a complete system assessment.

What supply voltage range does the unit accept?

The rated three-phase supply range is 230 to 440 V, with specified supply voltage limits of 195 to 484 V.

What motor power can it control?

The ATS22C32Q is rated for a 90 kW motor at 230 V and a 160 kW motor at either 400 V or 440 V under standard application conditions.

What is the rated starter current?

The starter has an IcL rating of 320 A when connected in the motor supply line for standard applications. Its factory current setting is 285 A.

How does the unit control motor starting?

It uses torque-controlled starting, with starting current limited to approximately 3.5 times the configured nominal current. This provides smoother acceleration than direct-on-line starting.

Does this soft starter have an internal bypass?

Yes. An internal bypass is incorporated to reduce power losses and heat generation once the motor has reached normal running conditions.

What control circuit voltage is required?

The control circuit requires a nominal 230 V AC supply at 50 or 60 Hz, with an operating tolerance of -15% to +10%.

Which communication interface is provided?

The unit includes Modbus serial communication through an RJ45 connector. It uses an RS485 multidrop interface and supports transmission rates of 4,800, 9,600 or 19,200 bps.

How many digital inputs and relay outputs are included?

Three 24 V DC positive-logic digital inputs are provided, identified as LI1, LI2 and LI3. The unit also has two configurable changeover relay outputs, R1 and R2.

What protection functions are built into the starter?

Integrated functions include motor thermal protection, starter thermal protection and monitoring for line phase failure. A 750-ohm PTC probe input is also available for motor temperature monitoring.

What are the unit's dimensions and weight?

The unit measures 425 mm high, 206 mm wide and 299 mm deep. Its stated net weight is 33 kg.

How should the soft starter be mounted?

It should be installed vertically within 10 degrees of the upright position. Adequate space and enclosure ventilation are required to maintain bottom-to-top airflow and dissipate generated heat.

Does the unit require an electrical enclosure?

Yes. Its IP00 rating means it is an open device and must be installed within a suitable enclosure selected for the operating environment and required ingress protection.

What cooling method does it use?

The starter uses forced-convection cooling and includes a heat sink. The surrounding enclosure must allow sufficient airflow to prevent excessive operating temperatures.

What is the permitted operating temperature range?

It can operate from -10°C to 40°C without current derating. Operation from above 40°C up to 60°C requires current derating of 2.2% for each additional degree Celsius.

Can it operate at elevated altitudes?

The unit can operate at altitudes up to 1,000 metres without derating. Between 1,000 and 2,000 metres, the current must be derated by 2.2% for every additional 100 metres.

Can it be connected inside a motor's delta winding?

Yes. It may be connected either in the motor supply line or in series with each winding of a compatible delta-connected motor. Inside-delta selection and wiring require careful current calculations and correct motor terminal access.

What power connections are required?

The power terminals use 30 mm by 5 mm bars with M12 bolts. The specified terminal tightening torque is 57 Nm, and conductor sizing must be confirmed against the installation method, applicable regulations and motor current.

Which utilisation category applies to this soft starter?

The ATS22C32Q is classified under utilisation category AC-53A for semiconductor motor controllers and starters.
