Anleitung Zusammenfassung


Access will also be needed to the temperature sensor, overflow tube temperature sensor, and liquid level probe located on the tank lid and to the triac assembly located beneath the tank. .0000 P1772 FIG. 1 ELECTRONIC CONTROL P1773 FIG. 2 TRIAC General: This system controls the liquid level and water temperature of the dispenser. These two functions act independently of each other and should be tested separately. Liquid Level Control Flow Charts 10420 011599 SERVICE (cont.) Electronic Controls (cont.) Liquid Level Control Test Procedure 1. Disconnect the dispenser from the power source. 2. Check the voltage across terminals 3 & 4 of the electronic control assembly with a voltmeter. Connect the dispenser to the power source. The indication must be: a.) 100 to 120 volts ac for 100 to 120 volt models or b.) 200 to 240 volts ac for 200 to 240 volt models or c.) 230 volts ac for 230 volt models. 3. Disconnect the dispenser from the power source. If voltage was present as described, proceed to #4. If voltage was not present as described, refer to the Wiring Diagrams and check the dispenser wiring harness. 4. Remove the pink wire from terminal 5 of the electronic control assembly. 5. Check the voltage across terminals 1 & 4 of the electronic control assembly with a voltmeter. Connect the dispenser to the power source. The indication must be: a.) 100 to 120 volts ac for 100 to 120 voltmodels or b.) 200 to 240 volts ac for 200 to 240 volt models or c.) 230 volts ac for 230 volt models after a delay of approximately 5 seconds. 6. Disconnect the dispenser from the power source. If voltage was present as described, the liquid level control of the system is operating properly, proceed to #7. If voltage was not present as described, replace the electronic control assembly and the temperature sensor in the tank lid. NOTE - Each electronic control assembly is calibrated to a temperature sensor. Both components MUST be replaced as a set. Temperature Control Flow Charts 10420 091902 SERVICE (cont.) Electronic Controls (cont.) 7. Reconnect the pink wire to terminal 5 of the electronic control assembly. 8. Loosen the compression fitting, remove the probe from the tank lid, and inspect it for mineral deposits. Replace it if necessary. Keep the exposed ends of the probe away from any metal surface of the dispenser. 9. Check the voltage across terminals 1 & 4 of the electronic control assembly with a voltmeter. Connect the dispenser to the power source. The indication must be: a.) 100 to 120 volts ac for 100 to 120 volt models or b.) 200 to 240 volts ac for 200 to 240 volt models or c.) 230 volts ac for 230 volt models after a delay of approximately 5 seconds. 10. Touch the screw head end of the probe to the dispenser housing. The indication must be 0. 11. Move the probe away from the dispenser housing. The indication must again be: a.) 100 to 120 volts ac for 100 to 120 volt models or b.) 200 to 240 volts ac for 200 to 240 volt models or c.) 230 volts ac for 230 volt models after a delay of approximately 5 seconds. 12. Disconnect the dispenser from the power source. Temperature Control Flow Charts (cont.) If voltage was present as described, reinstall the probe, the sensing function of the system is operating properly. If voltage was not present as described, check the pink probe wire and the green ground wire for continuity and/or replace the probe. Temperature Control Test Procedure 1. Disconnect the dispenser from the power source. 2. Check the voltage across terminals 3 & 4 of the electronic control circuit board with a voltmeter. Connect the dispenser to the power source.The indication must be: a.) 100 to 120 volts ac for 100 to 120 volt models or b.) 200 to 240 volts ac for 200 to 240 volt models or c.) 230 volts ac for 230 volt models. 3. Disconnect the dispenser from the power source. If voltage was present as described, proceed to #4. If voltage was not present as described, refer to the Wiring Diagram and check the dispenser wiring harness. 4. Connect the dispenser to the power source and place the tank heater switch in the “ON” position. 5. Observe the red indicator on the electronic control circuit board. 6. Disconnect the dispenser from the power source. 10420 091902 SERVICE (cont.) Electronic Controls (cont.) If the indicator was on or blinking, the temperature sensor is operating properly, proceed to #7. If the indicator was off, check the sensor connection on the electronic control circuit board and/or replace the temperature sensor and the electronic control assembly. NOTE - Each temperature sensor is calibrated to an electronic control assembly. Both components MUST be replaced as a set. 7. Check the voltage across the tank heater terminals with a voltmeter. Connect the dispenser to the power source. The indication must be: a.) 100 to 120 volts ac for 100 to 120 volt models or b.) 200 to 240 volts ac for 200 to 240 volt models or c.) 230 volts ac for 230 volt models, while the red indicator on the circuit board ...
