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 motordriven 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.
Features
The interaction of the ATC6500 with the switching devices has been exhaustively tested, but
does not absolve plant operators from their own responsibility.
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.

The following chapter contains information on:
● Transfer control
● Controlling the switching devices
● Voltage measurement
3.1 Transfer control
Fundamental information on the topic of transfer control is provided below.
Transfer with switch disconnectors / transfer switching equipment with motor operator
Switching devices with motor operator are required for this application. These can make
short-circuit currents and conduct them to a limited extent (1 sec. current), but cannot break
them.
Transfer with circuit breakers with motor operator
The transfer in this case is performed by means of motor-driven circuit breakers. These can
make and conduct short-circuit currents, and also break them in the event of an overload.
The ATC6500 functions as transfer switching equipment in connection with two Siemens
3VA molded case circuit breakers with motor operators, and in connection with two 3WL or
3WT air circuit breakers.
3.1.1 Network/network application
In the network/network application the load is normally connected to the main supply source
and is switched to the secondary supply source if an anomaly occurs in the main supply or if
an external signal is issued. By means of various setting options (interlock time, etc.) the
transfer behavior can be defined on a customer-specific basis.
You can find more information on this in the chapter Parameterization (Page 155).

Manual, 05/2019, L1V30538268002A-01

Applications
3.1 Transfer control
3.1.2 Network/generator application
For the network/generator application the load is normally connected to the main source
(Source 1). Following a deviation in the voltage or frequency, and after the defined delay
time, a start signal is sent to the generator (Source 2). If the generator supplies the desired
voltage, the load is transferred to the secondary source (generator) until the main source
supplies the desired supply quality.
The load is then transferred back to the main source and the generator is kept in operation
without load to allow it to cool (duration can be set by user). The ATC6500 sends a start /
stop command to the generator through a relay output and can receive digital signals from
the generator indicating its status (generator ready, OK to accept load, etc.) through
programmable inputs.
An automatic generator test can be programmed, i.e. the generator can be started at set
times to check its correct operation, even if the network is within the thresholds.
This is done by setting the execution interval, starting time, days of the week on which the
test is to be carried out, duration, etc. More information on the various setting options can be
found in chapter Parameterization (Page 155).
3.1.3 Generator/generator application
In this case two generators are controlled, each with a start-stop relay and feedback signals,
if available. In this application a rotation between generators can be programmed, i.e. the
load can be switched from one to the other at regular intervals, with the purpose of sharing
out the generator work equally.
It is also possible to set the time of day when rotation is to occur, so that the load supply is
cut off at a specified time. In case of a problem in either generator, the load is always
transferred to the one in standby mode.
3.1.4 Load management with the ATC6500
Apart from applications with two switching devices, the ATC6500 can additionally control one
tie breaker. The ATC6500 has five predefined application settings.
The application must be selected in accordance with with the requirement in menu P02
under the parameter P02.01 (see chapter P02 – General (Page 162)).
The following applications can be implemented:

3.2 Controlling the switching devices
3.2 Controlling the switching devices
The ATC6500 can control various devices for automatic transfer switching. How the control
of the switching devices can be implemented is shown below.
● Depending on the type of transfer device used, the appropriate circuit diagram shall be
used (see chapter Connection (Page 83)), as well as the programmable inputs/outputs on
the ATC6500 (see chapter Inputs and outputs of the ATC6500 (Page 144)).
● Programmable outputs are set by default for the use of circuit breakers (see chapter P13
- Digital outputs (Page 180))
● The application is to be selected in accordance with the requirement (see chapter Load
management with the ATC6500 (Page 20) and chapter Parameterization (Page 155))
● The device status inputs (e.g. status of circuit breakers) shall be wired according to the
circuit diagram, so as to ensure reliable system operation.
● Nonetheless, it is possible to manage without wiring the status inputs. This enables the
programmable inputs to be used for other functions. In this case the device behaves as if
the status feedback messages were received immediately.
● If the device status inputs are not used, then after power-on the ATC6500 sends an
"open" command, in order to put the switching devices in a defined status.
● If the device status inputs are used, then after power-on the ATC6500 does not send any
commands to the breaker. The corresponding switching devices are not controlled until
anomalies occur in the network.
● Internal control relays are neither electrically nor mechanically interlocked.

Applications
3.2 Controlling the switching devices
3.2.1 Controlling motor-driven circuit breakers
The control of motor-driven circuit breakers requires four outputs (open and close commands
for Source 1 and Source 2) and two inputs for circuit breaker status feedback for the
application with two circuit breakers. If a further circuit breaker is used (see chapter Load
management (Page 20)) an additional 2 outputs (the commands Open / Close for the tie
breaker) and one input for the status of the tie breaker must be wired. For the control of the
tie breaker additional outputs can be attached by means of expansion modules.
Additional optional inputs may be required for alarm signals and TRIP.
● Open and close commands can be output as a continuous signal or a pulse. For the
continuous signal, the pulse is applied continuously until the circuit breaker has reached
the required position.
● The signal type (continuous signal or pulse) for the two circuit breakers can be selected
by setting the appropriate parameter under P08.01 in menu P08 to "Brk. Pul." or "Brk.
Con.". The control of the tie breaker is defined by parameter P02.22 in menu P02. For
this too, the signal setting can be adapted accordingly.
● The status for TRIP is ignored for a 15-second window every time an open command is
sent to the circuit breakers. This prevents a false alarm from being triggered if the circuit
breakers temporarily signal the TRIP status through their alarm switches while opening.
This has no effect on the function of the circuit breaker.
● If feedback inputs (circuit breaker status) are used and the circuit breaker does not close,
a second attempt is made before triggering an alarm.

3.2.2 Controlling remotely operated transfer switching equipment
The control of remotely operated transfer switching equipment (single motor operator) is
similar to the control of motor-driven circuit breakers, however it requires only three outputs
(close Source 1, open both sources, close Source 2) and two inputs for the status of the
transfer switching equipment.
● The command mode (continuous signal or pulse) can be selected by setting the
appropriate parameter under P08.01 in menu P08 to "Chg. Pul." or "Chg. Con.".
