• Safety instructions (multiple languages)
1.3 Further documents
The following documents are provided electronically via www.camillebauer.com:
• Safety instructions SIRAX BT5200
- Operating Instructions SIRAX BT5200
• Data sheet SIRAX BT5200
2. Safety notes

Device may only be disposed in a professional manner!

The installation and commissioning should only be carried out by trained personnel.
Check the following points before commissioning:
- that the maximum values for all the connections are not exceeded, see „Technical data“ section,
- that the connection wires are not damaged, and that they are not live during wiring,
- that the power flow direction and the phase rotation are correct.
The instrument must be taken out of service if safe operation is no longer possible (e.g. visible damage). In this case, all the connections must be switched off. The instrument must be returned to the factory or to an authorized service dealer.
It is forbidden to open the housing and to make modifications to the instrument. The instrument is not equipped with an integrated circuit breaker. During installation check that a labeled switch is installed and that it can easily be reached by the operators.
Unauthorized repair or alteration of the unit invalidates the warranty.
3. Device overview
The SIRAX BT5200 is a top-hat rail mounted Transducer and used to measure and convert AC Current input into an proportional DC current or voltage output signal. Input Current and Output Voltage/Current is displayed on LCD and indicated by LED's.
4. Mechanical mounting
The SIRAX BT5200 is designed for panel mounting.

Please ensure that the operating temperature limits are not exceeded when determining the place of mounting (place of measurement): 0 ... +45 °C
4.1 Mounting
Dimensional drawing BT5200: See section 10
Any mounting position is possible. Device may be clipped onto a top-hat rail according EN 50022.

Disassembly of the device requires that all connected wires be without current. First, remove all push terminals and the wires of the current and voltage inputs. Ensure that possible current transformers are short-circuited before the current connections on the device are opened. Release the transducer from a top-hat rail.

Ensure under all circumstances that the leads are free of potential when connecting them!
5.1 General safety notes

Please observe that the data on the type plate must be adhered to!
The national provisions have to be observed in the installation and material selection of electric lines!

Torque: 0.5 ... 0.6Nm rsp. 4.42 ... 5.31 lbf in
Terminal A, B, G
Single wire: ≤ 1,5mm2 or multiwire with end splices: 2× 0,5mm2
Torque: max. 0.5 Nm rsp. 4.42 lbf in
5.3 Inputs

No fuse may be connected upstream of the current measurement inputs!
When using current transformers their secondary connectors must be short-circuited during installation and before removing the device. Never open the secondary circuit under load.
The connection of the inputs depends on the configured system (connection type).
5.4 Power supply

A marked and easily accessible current limiting switch has to be arranged in the vicinity of the device for turning off the power supply. Fusing should be 10 Amps or less and must be rated for the available voltage and fault current.

5.6 Modbus interface RS485
Via the optional Modbus interface measurement data may be provided for a superior system.

1) One ground connection only. This is possibly made within the master (PC).
Rt: Termination resistors: 120 Ω each for long cables (> approx. 10 m)
Rs: Bus supply resistors, 390 Ω each
The signal wires (A, B) have to be twisted. G can be connected via a wire or via the cable screen. In disturbed environments shielded cables must be used. To avoid the possibility of loop currents, an Earth connection should be made at one point on the bus. Supply resistors (Rs) have to be present in bus master (PC) interface. Stubs should be avoided when connecting the devices. A pure daisy chain network is ideal.
You may connect up to 32 Modbus devices to the bus. A proper operation requires that all devices connected to the bus have equal communication settings (baud rate, transmission format) and unique Modbus addresses.
The bus system is operated half duplex and may be extended to a maximum length of 1200 m without repeater.
6. Commissioning

Before commissioning you have to check if the connection data of the device match the data of the plant. If so, you can start to put the device into operation by switching on the power supply and the measurement inputs.

11. Interface Definition Modbus RTU
SIRAX BT5200 supports Modbus RTU protocol (RS485).
The permissible address range for the BT5200 is between 1 and 247. Broadcast Mode (address 0) is not allowed.
The maximum latency time of an BT5200 is 200ms i.e. this is the amount of time that can pass before the first response character is output.
After sending any query through software (of the Master), it must allow 200ms of time to elapse before assuming that the BT5200 is not going to respond. If slave does not respond within 200 ms, Master can ignore the previous query and can issue fresh query to the slave.
11.1 Modbus functions
Following code functions are provide:
| Function code | Function Address | |
| 03 Read holding registers 40001 to 40040 | ||
| 04 Read input registers 30001 to 30002 | ||
| 16 Presets multiple registers 40001 to 40040 | ||
Example of read out measurement
Query:
| Device address Function code Start address Nr. of register CRC | |||
| 0x01 0x04 0x0006 | 0x0002 | 0x91CA | |
Response:
| Device address | Function code | Nr. of databytes | Databytes 0 ... 3 | CRC |
| 0x01 | 0x04 0x04 | 0x3C52C75D | 0xC5CC |
Example of set slave address to 2
Query:
| Device address | Function code | Start address | Nr. of register | Nr. of bytes | Databytes 0...3 | CRC |
| 0x01 | 0x10 | 0x000E | 0x0002 | 0x04 | 0x40000000 | 0x67E3 |
Response:
| Device address | Function code | Start address | Nr. of register | CRC |
| 0x01 | 0x10 | 0x000E | 0x0002 | 0x200B |
Exception Cases: An exception code will be generated when BT5200 receives ModBus query with valid parity and error check but which contains some other error (e.g. Attempt to set floating point variable to an invalid value). The response generated will be "Function code" + 0x80.
| 01 | Illegal function | The function code is not supported. |
| 02 | Illegal data address | Attempt to access an invalid address or an attempt to read or write part of a floating point value. |
| 03 | Illegal data value | Attempt to set a floating point variable to an invalid value. |
11.2 Data types
All information are displayed as 32-bit float. There is no representation for floating point numbers in the Modbus specification. But as a matter of principle any desired data structure can be casted to a sequence of 16Bit registers.
The IEEE 754 standard as the most often used standard for the representation of floating numbers is applied.
• The first register contains the bits 16 – 31
• The second register contains the bits 0 – 15
