8. 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:
Disk Brush ____________
stage 1: xxx V
(cannot be evaluated because of (cannot be evaluated because of
value variation caused by the pulses)
stage 2: xxx V
(cannot be evaluated because of
value variation caused by the pulses)
value variation caused by the pulses)
stage 3: approx. 5.0 V
stage 4: approx. 6.7 V
stage 5: approx. 8.7 V
stage 6: approx. 13.2 V
g pp
stage 7: approx. 17.8 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
t t d ith h d b tt d th LED li ht measurement was executed with charged battery and three green LEDs alight.
