DIGITAL BREW TIMER (Late Models)
P2201
FIG. 4 DIGITAL BREW TIMER
Location:
The timers are located inside the front of the trunk
on the upper right side of the component brackets.
Test Procedure.
NOTE:
Do not remove or install wires while timer board
is installed. Pressure applied to one side may cause
damage to the board.
1. Disconnect the brewer from the power source and
remove the front access panel.
2. Remove the one #8-32 screw securing circuit
board to the mounting bracket.
3. Remove circuit board and spacers (as required).
4. With a voltmeter, check the voltage across terminals
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.
b) 200 or 240 volts ac for two wire 200 or 240 volt
models and three wire 120/240 volt models.
c) 100 volts ac for two wire 100 volt models.
5. Disconnect the brewer from the power source.
If voltage is present as described, proceed to #6.
If voltage is not present as described, refer to the
Wiring
Diagrams
and check the brewer wiring harness.
6. Disconnect the white/blue wire from terminal TL3
and the blue/black wire from terminal TL5. With a
voltmeter, check for continuity across the two wires
when the “ON/OFF” switch is in the “ON” position
(upper) and the START switch is pressed. Connect
the brewer to the power source. The indication
must be:
a) 120 volts ac for two wire 120 volt models.
b) 200 or 240 volts ac for two wire 200 or 240 volt
models and three wire 120/240 volt models.
c) 100 volts ac for two wire 100 volt models.
If continuity is present as described, reconnect the
wires and proceed to #7.
If continuity is not present as described, refer to the
Wiring Diagrams
and check the brewer wiring har-
ness.
7. With a voltmeter, check the voltage across terminals
TL1 and TL4 when the “ON/OFF” switch is in the
“ON” position. Connect the brewer to the power
source. The indication must be 0 volts.
If voltage is as described, proceed to #8.
If voltage is not as described, disconnect the brewer
from the power source and replace the timer.
8. With a voltmeter, check the voltage across termi-
nals TL1 and TL4 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 as follows:
a) 120 volts ac for two wire 120 volt models.
b) 200 or 240 volts ac for two wire 200 or 240 volt
models and three wire 120/240 volt models.
c) 100 volts ac for two wire 100 volt models.
If voltage is present as described, the brew timer is
operating properly. Reset the timer as required, to
obtain the desired brew volume.
If voltage is not present as described, disconnect the
brewer from the power source and replace the timer.
Removal and Replacement:
1. Remove the one #8-32 screw securing circuit
board to the mounting bracket.
2. Remove circuit board and spacers (as required).
