Page 3: Overview
Communication is established via digital signal Monitor FTMU using Modbus. Design The monitor consists of a sensor body with Lindab Safe gaskets. Two flow sensors are mounted on the sensor body and connected to a display unit. The display unit is mounted ontop of a shelf on the sensor body. -
Page 4: Planning
Planning The longer distance to disturbance, i.e. the longer straight duct before the Monitor, the higher the measurement accuracy will be. However this is not the only factor which affects the accuracy of the measurement. The rotation of the Monitor and hence the positioning of the first flow sensor has an impact on the uncertainty of the measurement. - Page 5 Measurement uncertainty ± % or 1 l/s depending wich is the greatest 2-4·Ød >4-5·Ød >5·Ød Disturbance * Placement of first flow sensor Ød Duct diameter Reducer decrease Ød Reducer Duct diameter increase T-piece Inner radius Ød T-piece Outer radius (Not recommended) Ød Ød T-piece...

Page 6: Mounting
Mount the Monitor into the air duct system according to the mounting instructions for Lindab Safe. Do not use the flow sensors as handles when you mount the Monitor since this may cause damage and changes in their posi- tions might effect the measurement accuracy. - Page 7 Digital connection Connect A on the RTU to -A on the display unit and B to +B. When connecting more than one Monitor in series it is impor- tant to keep connecting A to A and B to B since crossing them will stop Modbus from working. The shield in the RS485 cable should be continuous over the entire bus, it should ne connected to ground before or at the first UltraLink and at ®...

Page 9: Display
Display The display can show useful information both with the green diode (status light) and with parameters in the LCD. By short pressing the mode button you can change the displayed parameter. If the button is pressed for more than 5 seconds (long press) then the configuration menu will be visible. - Page 10 Analog output settings #ADDR Name Unit Standard Comment 0 = 0-10 V 1 = 10-0 V Analog Output 1 Level Configuration 4x400 2 = 2-10 V 3 = 10-2 V Display: Analog Output 1 Unit Configuration 0 = Flow 4x401 1 = Temperature Analog Output 1 Temperature Minimum 4x402...
