2. TECHNICAL DESCRIPTION
2.1. Application
ATS-9 is automatic transfer switch controller dedicated for LV switchgear. The device is especially dedicated for
switchgears serving as auxiliary voltage supply system including diesel generator incoming feeders. An Incoming
feeder where unplanned outage occurs is automatically switched off and the controller immediately sends switch
on command to one of stand-by supplies according to set priority. Signalling of failures provides the staff precise
and immediate information about occurring alert states. The controller provides also event recorder function. The
records can be transferred to SCADA system with fiber optic port, RS-485 port or ethernet port. The
communication protocol is chosen from one of the available protocols from the list as follows: ZEG, IEC 60870-5-
103 or (optional) MODBUS, DNP-3, IEC 61850.
Depending on auxiliary voltage level, the device is provided in two versions:
 ATS-9 of Upn 230V AC/DC
 ATS-9 of Upn 110V AC/DC
2.2. Main features
The main features of ATS-9 are:
 standard rack 19” enclosure 19”/4U/160

2.3. Construction
ATS-9 is enclosured in standard rack cassette of dimensions: 19”/4U/160. Each cassette is equipped with 32
RGB LED diodes for disturbance signalling purposes (Fig. 1). 7” LCD display main task is to visualise of switchgear
topology with current breakers states. LCD display serves as interface for settings and configuration purposes as
well. The device consist of two main parts:
 the front panel (equipped with RGB LED diodes and 7” LCD display)
 logical unit (enclosured in standard 4U cassette, equipped with input/output modules, supply module,
communication module)
Device construction allows to mount separately the front panel and the logical unit. The device can be mounted
in any place, while the front panel could be mount in desired place, for example at detachable cabinet frame. On
the front panel (Fig. 1) the function buttons F1-F6 are located. Function buttons are used for setting the priority of
supply voltage. ON/OFF buttons allows to block alarm and failure signals. Alarm C buttons is used for quitting
alarm signals.

4. FUNCTIONAL PROPERTIES
4.1. Principle of operation
ATS-9 is freely programmable device which by: light indicators on front panel, LCD display and set of relay
outputs, signals the current condition of auxiliary voltage switchgear. The signals can be grouped and individually
assigned to visual indicators and signalling outputs. Inputs can be picked-up by energising them or by voltage
drop. Input signal can be delayed by timer of duration up to 25 sec. Block diagram of the device is shown at Fig.
4 (page 15). Diagram of connection manners of logical unit and front panel are shown at Fig. 5 (page 16). Fig. 5
a presents the logical unit mechanically and electrically connected to front panel by 32 pins connector. At Fig. 6
b the connection by RJ45 wire is shown. In this case, the front panel and logical unit are mount separately. Fig 6
c presents the possibility of connection two front panels with one logical unit by RJ45 wire. This arrangement
allows to present the same group of signals in two different places.

Fig. 5. Block diagram of connection manners of front panel and logical unit
Cooperation with standard switchgear topology
ATS-9 provides voltages supervision on switchgear busbars and feeders. In standard 3-breakers topology (two
incoming feedes, two busbar section and coupling breaker) the voltage is supervised in 4 points:
 feeder A
 feeder B
 busbars section A
 busbars section B
In addition, the controller receives the signals of:
 circuit breakers positions
 circuit breakers ready-to-close statuses
 trip signals of each breaker
In normal operation, section A is energised from TR1 transformer and section B is energised by TR2 transformer.
Circuit-breakers A and B are closed, while the circuit-breaker S is opened. In case of voltage drop on TR1 or TR2
transformer, the controller automatically starts its operation.
The breaker on which, outage situation occurs, is immidiatelly opened. Than breaker in coupling bay (CB "S")
receives the command to close. The time delay of CB "S" close can be adjusted.
In case of switchgear of more than 3 circuit-breakers, the operation is defined individually according to particular
case.

Repeating, non-repeating operation mode
ATS controller can be set as: repeating or non-repeating operation mode. In repeating operation mode, the ATS
controller immediatelly restores the standard arrangement of the switchgear when voltage on faulted feeder is
restored.
In non-repeating operation mode, the ATS controller do not restore the standard arrangment. If the voltages is
restored on faulted feeder, the controller waits for acknowledgment signal. Once the controller receives the
acknowledgment signal, restores the standard arrangement by sending open command to coupling breaker ("S")
and close command to breaker on which, the outage situation occured.

ATS - 9 Operating Manual
- 17 - DTR ATS-9_05.2017
Priority of feeder
The ATS controller allows the user to switch between the feeders. It can be performed by changing the priority of
power source. If the priority is set to "energise by TR1", the controller set breakers A and S as close and breaker
B as open. If the controller is set to priority "energise by TR2", the controller set breakers B and S as close and
breaker A as open. If changing the priority form A to B or B to A, the controller performs operation using an
appropriate order. Firstly, opens all the breakers, then closes the breaker suitable for selected priority and finally,
closes coupling breaker "S".
Fig. 10. Operation of ATS. Change od priority of incoming feeder.
Supervision of breakers position
In order to provide reliable operation, the ATS controller needs to receive the information of each breaker in two-
byte mode. The controller recognises the position correctly when receives the pair of signals "high" and "low" or
"low" and "high" at the same time (XOR gate logic). In case of receiving two "low" or two "high" signals, the
controller generates signal "CB ... faulty position" and turn into temporary blocked operation mode - the controller
performs no operation. If the controller receives proper pair of signals, automatically returns to ON status and
performs all operations according to the situation.

Blocking by trip signal
In case of fault on busbars, the CB is open by its overcurrent protection. In such situation, standard operation of
ATS controller, would cause "switch-onto-fault" situation. It could result in increasing the danger to staff and
equipment. To prevent such situation, the controller receives signal of trip condition of each supervised breaker.
In case of trip of any breaker, the controller turns to "latched interlock" and performs no operation. That status
must be ackwnoledged by the staff. Until the controller receives the acknowledgment signal, it generates no
commands.
Fig. 13. ATS operation in case of TRIP signal
ATS blocked mode
In order to allow to make intentional outage on switchgear busbars, the controller can be blocked by blocking
input. This can be use in case of neccessity of performing maintanance works on switchgear busbars. If the
blocking signal is active, the ATS controller performs no operation. The outage can be manually performed by the
staff.
Circuit-breaker control circuit fault
In case of unsuccesful operation of Circuit Breaker, the controller sends command 3 times again. If the position
of CB does not change to expected position, the controller recognise it as failure in control circuits and generates
signal "not ready-to-close".
Protection agains parallel operation of transformers
Standard switchgear wiring do not allow to close all CB at the same time. It would cause the parallel operation of
transformer what is in most cases not permitted. If, however, such sitation occurs, the ATS controller immidiatelly
sends open command to all breakers. After the time delay, the ATS controller closes proper pair of CB's according
to set priority.

4.2. Error codes

logic covers up to 255 logical nodes of which ~90 are defined as errors or faults. The typical list of errors arriving
