Check Sensors

  1. Connect dry-cell battery positive terminal to terminal No. 3 and dry-cell battery ground terminal to terminal No. 2, and connect the resistance (0.5 - 2 kΩ) between dry-cell battery positive terminal and terminal No. 1.
    NOTE:
    • Use new dry-cell batteries.
    • Using circuit tester, check the voltage of a single dry-cell battery is 1.6 V or more. And also check the voltage of three batteries in series is between 4.8 V and 5.2 V.
  2. Connect the circuit tester positive terminal to terminal No. 1, and the circuit tester negative terminal to terminal No. 2.
  3. Connect the battery positive terminal to terminal No. 5 and the battery ground terminal to terminal No. 4, and measure the voltages with the valve fully opened on LH side and with the valve fully closed on RH side.
    CAUTION: Do not power the motor for more than 10 seconds.
