8.0 WATER PUMP
For check purpose of the water pump function, the voltage of the different stages
can
be measured on power electronic module (A2:X2:6+7). In case of measurement with
measuring device Fluke 87, water in tank but suction turbine turned OFF, the result is:
plate brush
cylindrical brush
stage 1: xxx V
xxx V
(cannot be evaluated because of
value variation caused by the pulses)
stage 2: xxx V
xxx V
(cannot be evaluated because of
value variation caused by the pulses)
stage 3: approx. 5.0 V
5,7 V
stage 4: approx. 6.7 V
6,5 V
stage 5: approx. 8.7 V
7,5 V
stage 6: approx. 13.2 V
8,4 V
stage 7: approx. 17.8 V
9,4 V
When not using the indicated measuring device the result may vary since the voltage
is pulsed. The value depends on the battery voltage as well. In the present case
measurement was executed with charged battery and three green LEDs alight.
