DIGITAL TIMER (Late Models)
P2209.60
Location:
The timer is located on the front center of the component bracket.
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.
2.Remove the two
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 three wire 120/208 volt , 120/240 volt and 380 volt models.
b)208 volts ac for two wire 208 volt models.
c)240 volts ac for two wire 240 volt models.
d)230 volts ac for two wire 230 volt CE models.
e)208 or 240 volts ac for four wire 440 volt mod- els.
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.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 #7.
If voltage is not as described, disconnect the brewer from the power source and replace the timer.
7.With a voltmeter, check the voltage across ter- minals 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 three wire 120/208 volt, 120/240 volt and 380 volt models.
b)208 volts ac for two wire 208 volt models.
c)240 volts ac for two wire 240 volt models.
d)230 volts ac for two wire 230 volt CE models.
e)208 or 240 volts ac for four wire 440 volt mod- els.
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 two
2.Remove circuit board and spacers (as required).
3.Remove all wires from the timer.
4.Attach all wires to the replacement timer board prior to installation to the component mounting bracket. Refer to FIG. 33 when reconnecting the wires.
5.Install new circuit board with spacers (as required) to the component mounting bracket.
6.Adjust the timer as described below.
Timer Setting:
NOTE: Prior to setting or modifying volumes, check that the brewer is connected to water supply, the tank is properly filled, and a funnel and server are in place.
