3. Functional description
The SIRAX BT5500 is a programmable multifunctional transducer for measuring parameters in a three-phase 3- or 4-wire AC network. It ensures
the conversion of measured values into analog standard signals. The output signals are galvanically isolated from the input signals and the power
supply.
It can be parameterized via the RS485 interface with Modbus RTU or via the USB interface with the configuration software. The relay outputs signal
the overflow of the selected measured variables and the pulse output can be used to monitor the consumption of active energy.

connector. You have to provide a method for manually removing power from the device, such as a clearly labeled circuit breaker
or a fused disconnect switch.
When using voltage transformers you have to ensure that their secondary connections never will be short-circuited.
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.

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.
5.4 Power supply
A marked and easily accessible current limiting switch has to be arranged in the vicinity of the device for turning o the power
supply. Fusing should be 10 Amps or less and must be rated for the available voltage and fault current.
After switching the power supply on, the state diode should light up for a moment in red, and next should light up in green. The recording
confirmation in registers is signaled by a short extinction of the state diode.
The incorrect work is signaled by the state diode in the way described in the chapter 5.3 and 7.1.10. The data reception through the RS-485
interface is signaled by a pulsing of the Rx diode and the data transmission is signaled by a pulsing of the Tx diode.
The switching of the relay 1 - 4 on causes the lighting of the AL1 - AL4 diode.
5.5 Modbus interface RS485
Via the optional Modbus interface measurement data may be provided for a superior system. When using the USB port interface, the configurati-
on must be as follows: Device Address: 001; Baud rate: 57600; Parity: None; Stop bit: 1
The signal wires (A, B) have to be twisted. GND (G) can be connected via a wire or via the cable screen. In disturbed environments shielded
cables must be used. 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.
Indirect measurement with the use of 2 current transformers and 2 or 3 voltage transformers in a three-wire network

7. Programming
Before configuring the transducer, the driver should be installed. The transducer makes use of the software, which creates in the system, a
device of Universal Serial Bus – Multi-transducer and connected to it, the virtual COM port named Multi-transducer. The controller installation in
the Windows system causes the addition of a successive serial COM port to the list of ports serviced by the operating system. After connecting
the transducer to the USB port, the operating system informs about the appearance of a new device by means of the message.
Multi transducer
The creator to find a new hardware of the Universal Serial Bus will be started automatically. One must act in compliance with the creator
suggestions, choosing the installation from the indicated location and giving the path to controllers being on www.camillebauer.com. Controllers
are compatible with following systems: Windows 10, 2000, XP, Server 2003, Vista, server 2008, Windows 10 (x86 and X64). When installing
controllers, information about the lack of the controller digital signature can occur. One must ignore this information and carry on the installation.
After closing the creator, the system detect immediately the successive device – USB Serial Port. The creator for detection a new hardware will
start again.
After the successful ending of the installation, the system will inform about the installation of a new device. Two new devices appear in the device
manager – Multi-transducer and Port COM named: Multi-transducer.
7.1 Configuration of the transducer
The SIRAX BT5500 can be configuraed via software. The transducer has to be connected to the computer through the RS-485 converter, if the com-
munication will be performed using RS-485/Modbus Interface or directly through the USB port and after selecting Multi-transducer the conficuration
for the connection can be done.

After choosing the group: - minimal and maximal values, minimal and maximal values of individual parameters measured by the transducer in
the form of a list are displayed.
7.1.9 Archive of power profile
After choosing the group: - archive of power profile, following information is available -record in archived : from which sample to display and
number of records to be read.
The transducer is equipped with an archive allowing to store up to 1000 measurements of averaged active power. The averaged active power PAV can be
archived with time intervals 15, 30, 60 minutes (synchronized with the internal time clock) according to synchronization type in register 4005. In case of
work in the walking window mode, the arichiving follows in full quarters of an hour, despite the fact, that the step of the walking window lasts 15 seconds
and the walking window function can be activated any moment. Direct access to the archive is for 15 records including date, time and value located
in the range of addresses 1000 - 1077. In register 1000 is placed the position of the first (the oldest one) archived sample, and in register 1001 is the
position of the last archived sample (the latest one). In register 1002 is placed the first record of the fifteen ava ilable records located in re gisters 1003 -
1077. After writing the first read record (1 - 9000), the d ata of 15 records for read-out a re u pdated. Values 1e20 are in registers, in which samples a
re no t wri tten yet. The archive is organize d in a shape of a circular buer. After writi ng the nine thousan dth valu e, the next value overwrites the oldest
valu e with the number 0, and successively the next with the number 1, etc. If the value of the register 1000 is higher than 1001, it means, that the
buer at least once was overflowed. For example value 15 in the register 1000 and 14 in register 1001 means, that there was more than nine thousand
of samples and the oldest samples are from the record 15 to 9000, next from the record 1 to the latest record with the number 14. Erasing of average
power or change of the average time do not erase the archive. Automatic erasing of the archive and average power is made after current or voltage
transformer ratio is changed.
7.1.10 Error Codes
After connecting the transducer to the network, messages about errors can appear. Causes of errors are presented below:
– the state diode pulsates in red – lack of calibration or the non-volatile memory is damaged. One must return the transducer to the manufacturer,
– the state diode lights in red – inappropriate work parameters; one must configure the transducer again.
– the state diode pulsate alternately in red and green - error of phase connection sequence; one must interchange the connection of phase L2
with the phase L3.

9. Interface Definition Modbus (RS485)
The programmable multi-function transducer SIRAX BT5500 supports the MODBUS (RS485) RTU protocol (2-wire).
Connection should be made using twisted pair shielded cable. All "A" and "B" connections are daisy chained to-gether. The screens should also
be connected to the “Gnd” terminal. To avoid the possibility of loop currents, an Earth connection should be made at one point on the network.
Loop (ring) topology does not require any termination load. Line topology may or may not require terminating loads depending on the type and
length of cable used. The impedance of the termination load should match the impedance of the cable and be at both ends of the line. The cable
should be terminated at each end with a 120 ohm (1/4 Watt min.) resistor.
RS 485 network supports maximum length of 1.2km. Including the Master, a maximum of 32 instruments can be connected in RS485 network.
The permissible address range for The Meter is between 1 and 247 for 32 instruments. Broadcast Mode (address 0) is not allowed.
The maximum latency time of an Meter is 500ms 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 500ms of time to elapse before assuming that the Meter is not going to
respond. If slave does not respond within 500 ms, Master can ignore the previous query and can issue fresh query to the slave.
In the transducer, data are located in 16-bit and 32-bit registers. Process variables and transducer parameters are located in the register address
space in the way depending on the type of the variable value type. Bits in 16-bit register are numbered in the way depending on the variable
value type. Bits in 16-bit registers are numbered from the younger to the older (b0-b15). 32-bit registers contain numbers of float type in the
IEEE-745 standard. Register ranges are set in the table 3. 16-bit registers are presented in the table 4. 32-bit registers are set in tables 5 and 6.
Register addresses in tables 3,4,5,6 are physical addresses.
