Connect the nozzles to the duct (see Fig. 4). Depending the application you must use a specific connection set to connect the nozzles of the unit to the duct: To measure differential pressure, use PSET-QF or PSET-PVC set (pressure measurement is the unit default setting);...

Page 13: Verification Of Installation
DUAL DIFFERENTIAL PRESSURE TRANSMITTER WITH DISPLAY VERIFICATION OF INSTALLATION After switching on the power supply, the green ON/OFF LED on the printed circuit board must be on solid indicating that the unit is powered (Fig. 12 Operating indication). If the LED is OFF, check the connections. Blinking green RX and TX LEDs indicate that the unit has detected a Modbus network (Fig.
