Properties of the ATC6300 transfer control device
The ATC6300 transfer control device, in combination with Siemens circuit breakers with
motor operators (ACB, MCCB) or remotely operated transfer switching equipment (RTSE),
enables a transfer between a main and an alternative power source. The stability of the
power supply is analyzed by means of voltage taps upstream of the switching devices. User
limit thresholds (voltage, frequency, phase sequence) function as boundary conditions for
analyzing the quality of the power supply. If a threshold is undershot or exceeded for a
specific defined time, the ATC6300 transfer control device initiates a transfer to an
alternative power source. Thanks to the ATC6300 transfer control device, in combination
with Siemens circuit breakers with motor operators and transfer switching equipment (3VA,
3VL, 3WL, 3WT, 3KC3, 3KC4 - see chapter Compatible Siemens SENTRON switching
devices (Page 11)), a user-defined source transfer can be performed in accordance with IEC
60947-6-1.
The interaction of the ATC6300 with the switching devices has been exhaustively tested, but
does not absolve plant operators from their own responsibility. The functionality, comparable
with the ATSE, is provided by the assembly of RTSE with a controller.
Features
The key features of the ATC6300 transfer control device are:
●
Backlit LCD (128 px x 80 px) for displaying measurements, events and alarms in five
languages (German, English, French, Spanish, Italian)
●
Expandable with a maximum of two additional expansion modules with digital inputs and
outputs, and by means of communications interfaces (RS485, Ethernet)
●
3KC9000-8TL73 USB front interface for setting parameters on the front panel. It is not
necessary to open the control cabinet.
Technical functions
●
Auxiliary voltage supply is possible by means of taps from the supply sources (110-240 V
AC 50/60 Hz) or by means of a separate DC source (12-24 V DC).
●
Measurement of three-phase networks with or without neutral conductor, of two-phase
networks, and of single-phase networks.
●
Control of circuit breakers with motor operator, remote transfer switching equipment or
contactors.
●
Suitable for network/network, network/generator or generator/generator applications.
●
6 freely programmable digital inputs and 7 programmable relay outputs fitted to the
device.
