152.2 Wiring2.2.1 GeneralFig. 2.4: Connection of power supply, relay outputs, sensor and contact inputs.The HPM is equipped with 7 potential-free relay outputs, 8 sensor inputs (which canalso be used as contact inputs), 2 contact/pulse counter inputs and 2 continuous(0…10 V) universal inputs/outputs.The following chapters explain the use of the terminals more thoroughly.2.2.2 Main voltage17Sensor 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. 2.5: Connection of the power supplyThe HPM is a stand-alone controller with a 230V power supply. The power supplyalso feeds the components, which in turn are connected to the relays.NL 230 V ACPE
