Page 6: Mounting Instructions In Steps
HPS-X--LP 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--LP DIFFERENTIAL PRESSURE TRANSMITTER To measure differential pressure, use PSET-QF or PSET-PVC set (pressure measurement is the unit default setting); To measure volume flow, use PSET-PT Pitot tube connection set, PSET- QF or PSET-PVC connection set. If you use PSET-PT, you should enter the duct cross sectional area [cm²] in Modbus register 63.

HPS-X--LP DIFFERENTIAL PRESSURE TRANSMITTER Fig. 6 PWM (Open collector) connection External pull-up resistor 50—100 kΩ External voltage PWM GND source (5—30 VDC) Optional settings To assure correct communication, the NBT needs to be activated in only two devices on the Modbus RTU network. If necessary, enable the NBT resistor via 3SModbus or Sensistant (Holding register 9). -
Page 9: Operating Instructions
HPS-X--LP DIFFERENTIAL PRESSURE TRANSMITTER Fig. 7 Power / Modbus communication indication The status of the LEDs can be checked only when the unit is energised. Take the ATTENTION 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--LP DIFFERENTIAL PRESSURE TRANSMITTER 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 NO T E both LEDs blink again three times, the sensor will have carried out a calibration procedure instead of Modbus registers reset procedure.
