9
Carry out the tests with the squeegee mounted and the machine configured for drying.
10
Identify the wires G on the actuator connected to the fuse holder terminal F and corresponding
to the fuse F3.
11
Connect the clamp meter between the two wires G. It may be connected to either of the two wires G.
12
Set the clamp meter to A (amps) and DC.
13
Measure the current draw of the electromechanical actuator.
14
Turn the ignition key to position "1"
15
Press the suction motor button H to also command lowering of the squeegee.
16
Read and note the draw of the actuator E.
17
Pay attention as you have only a short time to make the reading.
18
Press the button H again to command raising of the actuator.
19
Read the absorption values of the actuator during raising.
20
Pay attention as you have only a short time to make the reading.
When you note the values of the actuator during lowering and raising, it is
immediately obvious, unlike you might think, that the values during lowering are
higher than those during raising. This is because during lowering, the actuator not
only positions the squeegee, but also continues its descent in order to preload the
springs responsible for ensuring that the squeegee blades exert the correct
pressure.
