Page 6: Mounting Instructions In Steps
HPS-X -2 DIFFERENTIAL PRESSURE TRANSMITTER The -F version of the product is not suited for 3-wire connection. It has separate ATTENTION grounds for power supply and analogue output. Connecting both grounds together might result in incorrect measurements. Minimum 4 wires are required to connect -F type sensors. - Page 7 HPS-X -2 DIFFERENTIAL PRESSURE TRANSMITTER 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);...

HPS-X -2 DIFFERENTIAL PRESSURE TRANSMITTER Fig. 7 Power / Modbus communication indication ATTENTION The status of the LEDs can be checked only when the unit is energised. Take the relevant safety measures! Green LED intensity can be adjusted between 0 and 100 % with a step of 10 % ATTENTION according to the value set in Holding register 80. - Page 10 HPS-X -2 DIFFERENTIAL PRESSURE TRANSMITTER NO T E Press and hold the tact switch until both LEDs on the PCB blink twice and hold it until both LEDs blink again three times. If the tact switch is released before both LEDs blink again three times, the sensor will have carried out a calibration procedure instead of Modbus registers reset procedure.
