FIG. 36 TIMER
TIMER (Early Models)
Location:
The timer is located inside the left front of the
brewer on the upper part of the component bracket.
Test Procedures:
1. Disconnect the brewer from the power source.
2. Disconnect the wires from the timer terminals
TL3, TL4 and TL5 and rotate the dial(s) fully
counterclockwise.
3. With a voltmeter check the voltage across termi-
nals TL1 and TL2 when the "ON/OFF" switch is in
the "ON" position. Connect the brewer to the power
source. The indication must be:
a.)120 volts ac for two wire 120 volt models, three
wire 120/208 volt models and three wire 120/240
volt models.
b.)200 to 240 volts ac for two wire 200, 230 or 240
volt models.
4. Disconnect the brewer from the power source.
If voltage is present as described, reconnect white/
orange wire to TL3, white/green wire to TL4, white/
yellow wire to TL5 and proceed to #5.
If voltage is not present as described, refer to the
wiring diagrams and check the brewer wiring harness.
5. Place an empty server under the funnel and select
1/2 gallon position on selector switch.
6. Check the voltage across terminals TL1 and TL4
with a voltmeter when the "ON/OFF" switch is in the
"ON" position. Connect the brewer to the power
source and press the start switch. The indication
must be:
a.)120 volts ac for two wire 120 volt models, three
wire 120/208 volt models and three wire 120/240
volt models for approximately 20 seconds for 1/2
gallon batch.
b.)200 to 240 volts ac for two wire 200, 230 or 240
volt models for approximately 20 seconds for 1/2
gallon batch.
7. Place an empty server under funnel. Select a 1
gallon batch and repeat #6. The voltage indication
should remain for approximately 40 seconds.
8. Select a 1-1/2 gallon or 1-3/4 gallon batch and
repeat #6. The indication should remain approxi-
mately 1 minute.
If voltage is present as described timer is operating
properly.
If voltage is not present as described, replace the
timer.
