General information 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.
Page 18
● Deviation of the phase displacement angle cos phi of the two sources Area of application The ATC6500 transfer control device can be used in conjunction with Siemens switching devices in areas in which a continuous power supply needs to be ensured.
General information 2.2 Compatible Siemens SENTRON switching devices Compatible Siemens SENTRON switching devices The ATC6500 permits the transfer between two supply sources using the following Siemens products. Note Transfer between circuit breakers A motor operator must be implemented to switch between circuit breakers.

General information 2.2 Compatible Siemens SENTRON switching devices 3KC ATC6500 transfer control device Manual, 05/2019, L1V30538268002A-01...
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.
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.
Applications 3.1 Transfer control 3.1.4.1 Application A: 2S – 0T SRC1 (kVA) = SRC2 (kVA) In this application two motor-driven circuit breakers with one outgoing load are used. The ATC6500 switches to one of the two sources, depending on the setting. The states can be obtained from the table: Source 1 (SRC1) Source 2 (SRC2)
Applications 3.1 Transfer control 3.1.4.2 Application B: 2S - 1T - PL SRC1 (kVA) > SRC2 (kVA) In this application three motor-driven circuit breakers are used. A distinction is made between prioritized load and non-prioritized load (NPL). On failure of the prioritized sources (in this case, Source 1), only the prioritized load is supplied by the secondary source (in this case, Source 2).
Applications 3.1 Transfer control 3.1.4.3 Application C: 2S – 1T – SI SRC1 (kVA) = SRC2 (kVA) In this application three motor-driven circuit breakers are used. A distinction is made between prioritized load and non-prioritized load (NPL). In this case, both loads are supplied by one source each in normal circumstances (both sources available).
Applications 3.1 Transfer control 3.1.4.4 Application D: 2S - 1T - AI SRC1 (kVA) > SRC2 (kVA) In this application three motor-driven circuit breakers are used. A distinction is made between prioritized load and non-prioritized load (NPL). In this application, both loads are supplied by one source each in normal circumstances (both sources available).
Applications 3.1 Transfer control 3.1.4.5 Application O: 2S - NPL SRC1 (kVA) > SRC2 (kVA) In this application three motor-driven circuit breakers are used. A distinction is made between prioritized load and non-prioritized load (NPL). In this application, on failure of the prioritized sources (in this case, Source 1), only the prioritized load is supplied by the secondary source (in this case, Source 2).
Applications 3.2 Controlling the switching devices 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)).
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.
Applications 3.3 Voltage measurement 3.2.3 Controlling contactors If contactors are used, two outputs (Close 1 and Close 2) and two status inputs are required. If an additional contactor is used as a tie breaker, an additional output (close tie breaker) and a status input are required.
Applications 3.3 Voltage measurement 3.3.1 P02 General ● The general system settings can be adjusted in Menu P02. In the menu the system configuration (application) is set (see chapter Load management with the ATC6500 (Page 20)). ● The nominal voltage and frequency are also set in P02. These are used as a reference for setting the percentage thresholds.
Applications 3.3 Voltage measurement 3.3.4 P09 Source Line CHK In this menu the limit thresholds for the sources are defined. ● 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.
Page 33
Applications 3.3 Voltage measurement The table below lists the measurements of the two sources. Some thresholds can also be deactivated for triggering the transfer. Measurement Description Can be deactivated Minimum voltage One or more phases too low Maximum voltage One or more phases too high Voltage deviation of the two sources The tolerated delta between the voltage Yes, if P08.14 is disabled...

The connected devices use this to detect the end of one command and the beginning of a new one. This time must be at least 3.5 times longer than the time required for sending one character.
MODBUS communication 10.3 MODBUS functions 10.3.1 Function 04: Read input register The MODBUS function 04 permits the reading of one or more consecutive registers from a memory of the slave. The register addresses are contained under the subsection Data library (Page 192).

Transfer The following chapter contains information on the transfer sequence. The ATC controls the breakers in a defined sequence depending on the selected application. The sequences are illustrated in the diagrams below. You can find more information about the parameters in the chapter Parameterization (Page 155). Please note that the transfers, and consequently the transfer times, depend on many conditions.
Transfer 12.1 Transfer types 12.1.2 IN-PHASE transition IN-PHASE transition aims to perform the transfer when the two sources are in synchronism. The parameters relating to synchronism can be defined in menu P08. As soon as the state of synchronism has been attained, the interlock time of the breakers (P07.n.02) is ignored, thus reducing the transfer time to a minimum.
Transfer 12.2 Transfer sequence 12.2 Transfer sequence 12.2.1 Transfer sequence for application A: 2S - 0T If Source 1 is regarded as the priority source, a transfer to the alternative source (Source 2) takes place and an automatic return to the priority source according to the diagram below: Note •...

Transfer 12.2 Transfer sequence Note • In addition to the various delay times for limit violation, the transfer is also influenced by the interlock times under parameter P07.n.02. • The tie breaker TB is always closed after the breakers of the sources. The time delay for closing of the tie breaker is defined under P02.30.

Transfer 12.2 Transfer sequence Failure of secondary source (Source 2) Note • In addition to the various delay times for limit violation, the transfer is also influenced by the interlock times under parameter P07.n.02. • The tie breaker TB is always closed after the breakers of the sources. The time delay for closing of the tie breaker is defined under P02.30.

ESD Guidelines Electrostatic sensitive devices (ESD) ESD components are destroyed by voltage and energy far below the limits of human perception. Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not electrostatically discharged. ESD components which have been subject to such voltage are usually not recognized immediately as being defective, because the malfunction does not occur until after a longer period of operation.
