2.1
Properties of the ATC6300 transfer control device
Features
Technical functions
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.
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

● 3KC9000-8TL73 USB front interface for setting parameters on the front panel. It is not

3.1.1
Network/network application
The following chapter contains information on:
● Transfer control
● Controlling the switching devices
● Voltage control
Fundamental information on the topic of transfer control is provided below.
In accordance with IEC 60947-6-1 we differentiate between two classes of transfer switching
equipment:
Motorized switching devices 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. In
connection with the remotely operated Siemens 3KC3 or 3KC4 transfer switching equipment,
a user-defined transfer can be realized according to class PC.
The transfer in this case is performed by means of circuit breakers with motor operators.
These can make and conduct short-circuit currents, and also break them in the event of an
overload. The ATC6300 functions as class CB transfer switching equipment in connection
with two Siemens 3VA or 3VL molded case circuit breakers with motor operators, and in
connection with two 3WL or 3WT air circuit breakers.
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 115).

Applications
3.1.2
Network/generator application
3.1.3
Generator/generator application
3.1 Transfer control
For the network/generator application the load is normally connected to the main source
(Line 1). Following a deviation in the voltage or frequency, and after the defined delay time, a
start signal is sent to the generator (Line 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 ATC6300 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 115).
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.

3.2 Controlling the switching devices
The ATC6300 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 wiring diagram shall be
used (see chapter Connection (Page 65)), as well as the programmable inputs/outputs on
the ATC6300 (see chapter Description and designation of the outputs (Page 110)).
● Programmable outputs are set by default for the use of circuit breakers (see chapter
Description and designation of the outputs (Page 110))
● 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 ATC6300 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 ATC6300 does not send any
commands to the switching device. The corresponding switching devices are not
controlled until anomalies occur in the network.
● Internal control relays are neither electrically nor mechanically interlocked.
The control of circuit breakers with motor operator requires 4 outputs (open and close
commands for Line 1 and Line 2) and 2 inputs for circuit breaker status feedback, plus any
additional optional inputs for alarm signaling and TRIP, as well as optional outputs for
controlling undervoltage releases.
● 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 command mode (continuous signal or pulse) can be selected by setting the
appropriate parameter under P05.07 in menu P05 to "Chg. Pul." or "Chg. Con."
● The TRIP status 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 send a TRIP signal 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.
Precise circuit diagrams as well as the parameters to be set can be found in chapter
Connection (Page 65) or in chapter Parameterization (Page 115).

Procedure for voltage measurement
The fundamentals of the procedure for adjusting the voltage measurement are explained
below.
The exact parameters can be found in chapter
3.3 Voltage control
The control of remotely operated transfer switching equipment (single motor operator) is
similar to the control of circuit breakers with motor operator, however it requires only three
outputs (close Line 1, open both lines, close Line 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 P05.07 in menu P05 to "Chg. Pul." or "Chg. Con."
Precise circuit diagrams as well as the parameters to be set can be found in chapter
Connection (Page 65) or in chapter Parameterization (Page 115).
If two contactors are used, two outputs (CL.1 and CL.2) and two status inputs are required.
● In this case the appropriate parameter under P05.07 in menu P05 must be set to
"Contactors" in the command mode.
Precise circuit diagrams as well as the parameters to be set can be found in chapter
Connection (Page 65) or in chapter Parameterization (Page 115).
This section illustrates how a voltage measurement is achieved for the ATC6300.
Parameterization (Page 115).
All parameters and settings can be adjusted by the user in the menus P02 (General), P05
(Changeover), P06 (Parameter Line 1) and P07 (Parameter Line 2).
● The general system settings can be adjusted in Menu P02, including the rated voltage
and frequency. These are used as a reference for setting the percentage thresholds.
● A voltage ratio (VT) can be set if a voltage is applied to the measurement inputs of the
device which is higher or lower that the set rated voltage. In this case the display and
setting of limit thresholds are also performed on the actual variables in relation to the
system.
● The device can be adjusted for the voltage measurement of three-phase networks with or
without neutral conductor, two-phase or single-phase networks (P02.06).

3.3 Voltage control
● In the case of three- or two-phase power supplies you can choose whether you want to
monitor the phase-to-phase voltage, the phase-to-neutral voltage, or both (P02.07). In
each case, the rated voltage set in P02.01 must be equal to the phase-to-phase voltage.
● The table below lists the measurements of the two lines. Some thresholds can also be
deactivated for triggering the transfer.
Maximum voltage One or more phases too high Yes
Phase failure Threshold value at which the device responds faster than when falling below
Voltage unbalance Voltage phases are not symmetrical to one another Yes
Yes
● Each measurement can be assigned a specific delay time. Measured anomalies (beyond
the threshold values) must be present for longer than the set delay times, before it can be
concluded that there is a line fault.
● When all the line parameters are restored within the specified thresholds, the delay time
must elapse before the restored line may be reconnected. This delay period is
determined by two independent parameters:
– P06.07 or P07.07 - delay time if the line is within the specified thresholds again (and
Line 2 or Line 1 is not available)
– P06.08 or P07.08 - delay time if the line is within the specified thresholds again (and
Line 2 or Line 1 is available)
● For the minimum and maximum voltages, two thresholds are defined in each case. One
for the point beyond which the voltage is no longer considered sufficient (e.g. P06.01,
threshold MIN trip voltage); and another which is closer to the rated voltage, defining the
point beyond which it is sufficient again (e.g. P06.02, threshold MIN reset).
The distance between these two thresholds determines the hysteresis. It is possible to
stipulate, for example, that the voltage may no longer be used when it falls below 80% of
the rated voltage, and that in order to be usable again, it must rise above 85%. This
defines a hysteresis of 5% (dead zone). The same principle is applied to the maximum
voltage.
● If the voltage is within the set thresholds when the device is switched on or reset, both
sources are considered to be in order (without considering the delay times), except when
the load is already supplied by a circuit breaker; then the delay times are taken into
consideration.
