PROGRAMMING THE BREWER (cont.)
SERVICE TOOLS
This function allows the testing of individual com- ponents and the ability to check switches for proper function. This function also tests the Soft Heat server's status on the brewer (in place or removed), and the funnel sensor coil's frequency (diagnostic tool for troubleshooting purposes only).
Testing individual components (outputs):
This will allow the operator to test the operation of individual components and outputs of the brewer. The components that can be individually tested are as follows:
SINGLE Brewers
Brew Valve
Bypass Valve
Funnel Lock (Optional)
Server
Refill Valve
Tank Heaters
Heater Contactor
DUAL Brewers
Left Brew Valve
Left Bypass
Left Funnel Lock
Left Server
Right Brew Valve
Right Bypass
Right Funel Lock
Right Server
Refill Valve
Tank Heaters
Heater Contactor
Procedure to test components (outputs):
1.Place brew funnel(s) into rails on the brewer (both sides on DUAL brewers).
2.Place a Soft Heat server(s) beneath the brew funnel(s).
3.Press and hold the upper right hidden switch until display reads UNITS. Release the switch. Continue to press and release switch until SERVICE TOOLS appears.
4.Press YES to run tests on various components and outputs within the brewer. Pressing NO will exit this function and advance to next function screen.
5.The display should read TEST OUTPUTS.
6.Press and release YES. The display should read: BREW VALVE on SINGLE brewers
LEFT BREW VALVE on DUAL brewers.
7.To test BREW VALVE, press ON. If the brew valve is functional, water should run from the brewer (left side on DUAL brewers)
8.Press OFF to end flow of water.
9.Press NEXT to advance to the next component to be tested.
NOTE: To bypass testing any component, press NEXT to advance to the next one, without testing the previ- ous component.
10.To test BREW BYPASS on SINGLE brewers or LEFT BREW BYPASS on DUAL brewers, press ON. If the bypass valve is functional, water should run from the brew bypass (left side on DUAL brewers).
11.Press OFF to end flow of water.
12.Press NEXT to advance to the next component to be tested.
13.To test FUNNEL LOCK on SINGLE brewers or LEFT FUNNEL LOCK on DUAL brewers, press ON. If the funnel lock is functional, the lock will come down to hold the funnel in place.
14.Press OFF to retract the funnel lock.
15.Press NEXT to advance to the next component to be tested.
16.To test SERVER on SINGLE brewers or LEFT SERVER on DUAL brewers, press ON. If the server and the sensor are functional, the light on the lower right corner of the server will illuminate.
17.Press OFF to end testing of server.
18.Press NEXT to advance to the next component to be tested.
19.For DUAL brewers, follow steps 7 through 15 to test the right side components.
20.To test REFILL VALVE, press ON. If the refill valve is functional, the sound of the valve operating will be heard.
21.Press OFF to end testing of refill valve.
22.Press NEXT to advance to the next component to be tested.
23.To test TANK HEATERS, connect a voltmeter across each of the tank heaters to check for voltage.
24.Press ON. The correct voltage should be present at the heater terminals.
25.Press OFF to end testing of the tank heaters.
