2.1 Features of the ATC6500 transfer control device
The 3KC ATC6500 transfer control device, in combination with Siemens motor-driven circuit
breakers (ACB, MCCB), 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 ATC6500 transfer
control device initiates a transfer to an alternative power source.
Apart from its use with two switching devices, the ATC6500 can control one additional motor-
driven circuit breaker. This enables a large number of applications with critical loads to be
implemented (for more detailed information, see chapter Load management with the
ATC6500 (Page 20)). It is also possible to implement an IN-PHASE Transition with the
ATC6500. In this application, the differences in frequency, voltage and phase angle of the
two sources are measured. The ATC waits for these parameters to be within a defined range
and then initiates a transfer when synchronism is present. The transfer takes place with open
transition, i.e. parallel network operation is not present. This creates a more stable load
transfer.
The interaction of the ATC6500 with the switching devices has been exhaustively tested, but
does not absolve plant operators from their own responsibility.
Features
The key features of the ATC6500 transfer control device are:
● Backlit LCD (128 x 80 pixels) for displaying measurements, events and alarms in eight
languages (German, English, French, Spanish, Italian, Portuguese, Polish, Russian)
● Integrated RS485 interface, expandable with a maximum of three additional expansion
modules with digital inputs and outputs, and by means of communication interfaces
(Ethernet)
● 3KC9000-8TL73 USB front interface for setting parameters on the front panel. The
parameterization by means of software therefore does not require the control cabinet to
be opened.
