Panasonic PAW-HPM 1 User Manual

162.2.3 Input terminalsThe HPM has the following input terminals:x Sensor input (PT1000, Nickel1000 or Nickel1000 LG): Only one type ofsensor can be used at any one time and has to be specified during the initialinstallation (see chapter “The start-up sequence”).x Contact input or counter input (for reading a pulse from a meter).x 0..10V input for sensors with 0..10V output or for a heat demand via signal(0..10V=0..150°C). These inputs can also be used as 0..10V outputs (see theoperating manual for more information).Sensors / contact17Sensor groundSensor NN1618 Sensor L 1519 Sensor Potential for 13 1420 Sensor Relay 1321 Sensor Not used 1222 Sensor Relay 1123 Sensor Potential for 9+11 1024 Sensor Relay 925 Contact / counter Not usedPE826 Contact / counter Relay 727 0…10 V Potential for 5+7 628 0…10 V Relay 529 Sensor ground Not used 430 Not used Relay 331 Not used Potential for 1+3 232 Not used Relay 1Fig. 2.6: Connection of sensors or contact inputsA sensor is connected to the assigned terminal and to the sensor ground. Exigosupports connection of up to 8 sensors. PT1000, Ni1000 and Ni1000LG sensors arenot poled, and it is therefore not necessary to differentiate between which wire shouldbe connected to the ground and which should be connected to the terminal.The sensor inputs can also be used as contact inputs.Room sensor with remote setpoint adjustmentTo connect a room temperature sensor with a remote setpoint potentiometer (PAW-HPMR4), all sensor inputs can be used that are still free and which have no functiononce the system diagram has been loaded. The sensor ground and the chosen inputterminals must to be connected to the sensor and the setpoint potentiometer in thePAW-HPMR4 (the sensor ground will probably have to be bridged).Sensor /contact
