P- 3.0.1 REMAINIING ON FOR AT LEAST 30 SECONDS
With the machine on, QUICKLY unplug the keypad’s green ribbon cable from the UI-MICS Board’s J4
connector. TWO (2) possible scenarios:
1)
IF the machine stays on after unplugging the cable: Place the machine into Heat Disinfect
and with the shunt door open allow up to one (1) hour. If the machine STAYS on see procedure number
P- 3.0.2 (page 707). If it turns itself off again see OTHER POSSIBILITIES below.
OTHER POSSIBILITIES: Swap in the following components (see Component List below) one at a
time, with known good, and in between if the machine remains on the last component swapped in
was the problem.
Component List:
1) Power Logic Board; 2) Power Logic Board cable; 3) Main Relay (K1). To LOCATE K1 refer to
Figure 132 (page 710).
2)
IF the machine turns off before unplugging the cable: The most likely culprit is the
keypad itself. Replace it HOWEVER, if the problem reoccurs see OTHER POSSIBILITIES below:
