  • Page 53: Testing Dc Voltage From The Push Auger Encoder

    Page 53 Testing DC voltage from the Push Auger Encoder. The push auger is equipped with a device called an encoder. It receives a voltage signal from the PCB (5VDC) and sends a (2.5VDC) back to the PCB to prove to the PCB that it is operating properly. If the PCB does not get the correct signal from the encoder, it will not allow the metering auger to turn.

  • Page 54: Testing Dc Voltage From The Temperature Sensor

    Page 54 Testing DC voltage from the Temperature Sensor The temperature sensor functions by receiving voltage from the PCB and returning a smaller voltage signal back to the PCB. The amount of voltage that the sensor sends back to the board is a direct relationship to the temperature at the sensor (10mV = 1°Celsius).
