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:
(SINGLE)
Brew Valve
Bypass Valve
Funnel Lock
Refill Valve
Tank Heater Relay
1. Place a funnel into the rails of the brewer (both
sides of the DUAL brewer).
2. Place a server beneath funnel (both sides of the
DUAL brewer).
3. Press and hold the right hidden switch until the dis-
play reads SET LANGUAGE. Press the right hidden
switch 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 (SINGLE brewers)
<- <- BREW VALVE (left side DUAL brewers).
To test the brew valve, press ON. If the brew valve
is functional, water should run from the funnel (left
for DUAL brewers).
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 (SINGLE brewers)
<- <- BYPASS VALVE (DUAL brewers).
To test the bypass valve, press ON. If the bypass
valve is functional, water should run from the funnel
(left for DUAL brewers).
9. Press OFF to end the flow of water.
10. Press NEXT to advance to the next component to
be tested:
FUNNEL LOCK (SINGLE brewers)
<- <- FUNNEL LOCK (DUAL brewers).
11. To test the FUNNEL LOCK, press ON. If the funnel
lock is functional, the lock will drop to hold funnel
(left funnel for DUAL brewers) in place.
12. Press OFF to retract the funnel lock.
13. For DUAL brewers, follow steps 5-12 to test the
right side components.
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 return to the TEST OUTPUTS screen.
To advance to the next function screen, TEST
SWITCHES, press NO. To exit programming, press
and release the ON/OFF switch (either for DUAL
brewers) to return to the MAIN SCREEN.
