The rotor contactor shall not be additionally controlled by any PLC or similar device. What's important is that

ASTAT's DO directly controls the rotor contactor, as rotor control is a real integrated part

Time motion control with a resolution of 3ms.

Selection and application suggestions:

1) Connect the contactor to a star shape instead of Δ。 The recommendation table is based on star connections.

2) All contactors are considered as the final short-circuit rotor contactors. This compensates for the additional heating of the contacts caused by short-term low magnetization and harmonic caused by the control of the main thyristor.

3) The closing operation of the contactor is carried out using the rotor current.

Typical value: 1,0-1.5 times the rated current of the rotor.

4) The disconnection operation of the contactor is carried out under zero rotor current.

5) The installation temperature is 55 degrees Celsius. Reduce values below 70 degrees Celsius.

6) These devices are often manufactured on the panels of steel cranes with conductive dust. All components

In open panels, it must comply with EN 60664, pollution level 4. We suggest keeping the contactor

Clean it by installing it in a reasonably sized enclosed compartment/box to avoid heating due to its own loss,

Alternatively, use sturdy contactors.

7) In order to obtain good control of property, a contactor with a short opening and closing time is needed. Consider the impact of incoming coil current on the size of the control transformer.

8) The lifespan (electrical lifespan) of the contacts is calculated as

Contactor mechanical system (mechanical durability).

9) For Δ The current capacity value of the connection, multiply the numbers in the table by 1,5 or 1,73, depending on

Manufacturer's recommendation. However, Δ- The connection increases voltage stress (shorter lifespan), the workload of panel wiring is greater, and the quality control measures for wire selection and tightening torque are stricter.

10) It is recommended to directly connect the contactor coil to the DO relay of the process I/O board, for use only

Introduce AC coil contactors with a current of 2A or less. For larger AC contactors and all DC contactors, pi batch relays should be used.

Using ABB contactors, A75 is the largest size with 110 V AC coils and EH 145 (old series)/A 110 (new series)

The maximum size (range), where the 230V AC coil still does not require a pilot relay.

11) The following time applies to AC coil contactors. The time may differ slightly from the directory value to match

Real time control system for ASTAT.

12) The listed ABB and Schneider contactors are made of traditional coils, while

Siemens adopts an electronic magnet system.

The rotor contacts should not be additionally controlled by any PLC or sister It is important that the
