Page 8: Verification Of Installation Instructions
DIFFERENTIAL PRESSURE TRANSMITTER VERIFICATION OF INSTALLATION INSTRUCTIONS When you switch on the unit the green LED (Fig 8 Power indication) should give out continuous green light. If it does, your unit is powered on. If this is not the case, check the connections again. - Page 9 DIFFERENTIAL PRESSURE TRANSMITTER Fig. 10 Sensor calibration and Fig. 11 Sensor calibration / Modbus register Modbus register reset tact switch reset / normal operation indication Reset of Modbus Registers procedure: Press button SW2 for 4 seconds until the blue LED on the printed circuit board (Fig. 11) blinks twice and keep pressing the button until it blinks three times.
- Page 10 DIFFERENTIAL PRESSURE TRANSMITTER To get correct calculation of the volume flow rate, the correct K‑factor of the NO T E fan / drive has to be written in holding register 17! ■ Input register 7 gives information about the current working range. In Standalone mode it contains the working range which is set by jumpers 1, 2 and 3.

Page 11: Modbus Register Maps
DIFFERENTIAL PRESSURE TRANSMITTER ■ Holding register 15 (40015) defines the minimum pressure limit. The default value is the minimum of the set range. When the measured pressure is below this value, input register 4 (“Min Pressure Limit Flag”) sets to '0', otherwise it is '1'. This register accepts values between -100 and 2.000. -
