Service and maintenance personnel, Planner. Scope This handbook is valid for all versions of the programmable multi-function transducer SIRAX BT5500. Some of the functions described in this document are available only, if the necessary optional components are included in the device.
• Phase active power factors ……………… Pf1, Pf2, Pf3 The SIRAX BT5500 can be mounted either on DIN Rail or directly on to a wall by mounting plate. Please ensure that the operating temperature limits are not exceeded when determining the place of mounting (place of measurement): –10 …...
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.

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.

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.
The currently measured value is copied out to the minimal and maximal value. e) clock: it is possible to set time and date synchronize the clock with the time on the PC (computer). PM 1002499 000 00 Device handbook SIRAX BT5500 10/28...
