PROGRAMMING THE BREWER (cont.)

PROGRAMMING FUNCTIONS - LEVEL 2 (cont.)

SERVICE TOOLS

This function allows the testing of individual components and the ability to check switches for proper function. This function also tests the funnel sensor coil’s frequency (diagnostic tool for troubleshooting purposes only).

Procedure to test components and outputs:

The following components can be individually tested: Left Brew Valve

Left Bypass Valve

Left Funnel Lock

Right Brew Valve

Right Bypass Valve

Right Funnel Lock Refill Valve Tank Heater Relay Tank Heater Triac

1.Place a funnel into the rails on both sides of the brewer.

2.Place a server beneath each funnel.

3.Press and hold the right hidden button until the dis- play reads SET LANGUAGE. Press the right hidden button until the display reads SERVICE TOOLS.

4.Press and release YES. The display should now read TEST OUTPUTS? Press and release YES to test individual components and outputs. Pressing NO will advance to the next programming function,

TEST SWITCHES.

5.The display should now read <- <- BREW VALVE. To test the left brew valve, press ON. If the brew valve is functional, water should run from the left funnel.

6.Press OFF to end the flow of water.

7.Press NEXT to advance to the next component to be tested.

NOTE: To bypass testing any component, press NEXT to advance to the next component without testing the previous one.

8.The display should now read <- <- BYPASS VALVE. To test the left bypass valve, press ON. If the bypass valve is functional, water should run from the left funnel.

9.Press OFF to end the flow of water.

10.Press NEXT to advance to the next component to be tested, <- <- FUNNEL LOCK.

11.To test the left FUNNEL LOCK, press ON. If the funnel lock is functional, the lock will drop to hold funnel in place.

12.Press OFF to retract the funnel lock.

13.Follow steps 5-12 to test the right side compo- nents.

14.To test the REFILL VALVE, press ON. If the refill valve is functional, the sound of the valve operating will be heard.

15.Press OFF to end testing of the refill valve.

16.Press NEXT to advance to the next component to be tested, TANK HEATR RELAY.

17.To test the tank heater relay, connect a voltmeter across each of the tank heaters to check for volt- age.

18.Press ON. The correct voltage should be present at the heater terminals.

19.Press OFF to end testing of the tank heater relay.

NOTE: The tank heater will automatically turn off if left on too long.

20.Press NEXT to advance to the next component to be tested, TANK HEATR TRIAC.

21.To test the tank heater triac, connect a voltmeter across each of the tank heaters to check for volt- age.

22.Press ON. The correct voltage should be present at the heater terminals.

23.Press OFF to end testing of the tank heater triac.

24.Press NEXT to return to the TEST OUTPUTS screen. To advance to the next function screen, TEST SWITCHES, press NO. To exit programming, press and release either ON/OFF button to return to the

MAIN SCREEN.
