ET 200SP motor starter

ET 200SP is a scalable, highly flexible and modular I/O system with IP20 degree of protection. As I/O modules, the ET 200SP motor starters are an integral part of this I/O system. They are switching and protection devices for single and three-phase loads and are available as direct-on-line or reversing starters.

Basic functionality

All versions of the ET 200SP motor starters have the following functionality:

• Fully pre-wired motor starters for switching and protecting any AC loads up to 5.5 kW from 48 V AC to 500 V AC
• Disconnection possible via fail-safe motor starters up to SIL 3 and PL e Cat. 4
• With self-assembling 32 A power bus, i.e. the load voltage is only fed in once for a group of motor starters
• All control supply voltages connected only once, i.e. when modules are added they are automatically connected to the next module
• Hot swapping is permissible
• Digital inputs can be used optionally via a 3DI/LC module
• Control of the motor starter from the control system and extensive diagnostics status via the cyclic process image
• Diagnostics capability for active monitoring of the switching and protection functions
• The signal states in the process image of the motor starter provide information about protective devices (short circuit or overload), the switching states of the motor starter, and system faults.

Use of fan

For motor starters with a 12 A rated current, the 3RW4928-8VB00 fan is included in the scope of delivery.

This fan can also be ordered as an option for motor starters with lower rated currents, if the boundary conditions demand this. For information on the ambient conditions for the use of motor starters, see chapter "Product overview" in the manual.

Designing interference-free motor starters

For interference-free operation of the ET 200SP station in accordance with IEC 60947-4-2 standard, use a dummy module before the first motor starter. The dummy module consists of the 6ES7193-6BP00-0BA0 or 6ES7193-6BP00-0DA0 BaseUnit and the 6ES7133-6CV15-1AM0 BU cover 15 mm.

The 15 mm BU cover protects the plug contacts of the BaseUnit against dirt.

Both can be ordered as accessories, see also Catalog ST 70.

Article No. scheme

¹⁾ For standard motors: Single- or three-phase asynchronous motors, single-phase AC motors, single-phase asynchronous motors, at 400 V AC and 500 V AC; the actual startup characteristics of the motor as well as its rated data are important factors here.

BaseUnits for motor starters

BaseUnits are components for accommodating the ET 200SP I/O modules. The self-assembling voltage buses integrated into the BaseUnits reduce wiring outlay to the single infeed (both of auxiliary and load voltage).

All modules following on the right are automatically supplied upon plugging the BaseUnits together, if BaseUnits are inserted with routing. The rugged design and keyed connection technology enables use in harsh industrial conditions.

The BaseUnits are available with various infeeds for the motor starters.

3DI/LC control module

This is a digital input module with three inputs for local motor starter functions such as "manual local control", "implementation of fast inputs" or "end position disconnection".

For a list of all the functions permitted by the 3DI/LC module, see Manual "ET 200SP Motor Starters", "Function overview" section https://support.industry.siemens.com/cs/ww/en/view/109479973 .

The module is plugged into the front of the motor starter from which it is supplied with a 24 V DC operating voltage.
