E2.1.7 The suction motor is not working
A
Correct the error as described in table E1.2.
1
Check there are no errors on the control panel
display, see paragraph E1.2.
B
If there are no errors, go to point 2.
A
If the fuse is burnt out, replace it.
2
Check the state of the fuse F4 protecting the
suction motor.
B
If the fuse is intact, go to point 3.
A
If there is voltage, go to point 5
3
Check the output voltage of the suction motor
connector, see paragraph B1.2.
B
If there is no voltage, go to point 4
A
If there is no continuity, restore it.
4
Check the continuity of the motor power wires.
B
If there is continuity, go to point 5.
A
If there is voltage, replace the suction motor with a
new one.
5
Check that there is a voltage of 10 V DC on
the control wires A3, see paragraph B1.
B
If there is no voltage, go to point 6
A
If there is not continuity in one or both of the two
wires, restore it.
6
Check the continuity of the negative and
positive control wires.
B
If there is no continuity, go to point 7
A
If there is a voltage of 36 V, replace the functions
board.
7
Read the output tension from the functions
circuit board. Place the negative probe of the
tester on pin B7 and the positive probe on the
positive insulator and command raising
through the control panel.
B
If there is no voltage, replace the control panel
circuit board with a new one.
E2.1.8 The squeegee does not move (up and down)
A
Correct the error as described in table E1.2.
1
Check there are no errors on the control panel
display, see table E1.2.
B
If there are no errors, go to point 2.
A
If the fuse is burnt out, replace it.
2
Check the state of the fuse F3 protecting the
squeegee actuator.
B
If the fuse is intact, go to point 3.
A
If the actuator is working, go to point 5
3
Check operation of the actuator manually, as
described in paragraph B2.2.
B
If the actuator is not working, go to point 4
A
If the actuator does not comply with the indications,
repair it.
4
Proceed to control the actuator manually on
the bench as described in paragraph B2.4.
B
If the actuator is not repairable, replace it.
A
If there is a voltage of 36 V briefly (max. 3 secs), the
board is functioning correctly. Go to point 6.
5
Disconnect the actuator connector and check
the output voltage from positions 1(-) and 2(+)
of connector CN3 on the control panel board.
B
If there is no voltage, replace the control panel
board.
A
If there is a voltage of 36 V briefly (max. 3 secs), go
to point 8.
6
Check the output voltage on the squeegee
connector, BROWN wire PIN 1 and WHITE-
BLUE wire PIN 2.
B
If there is no voltage, go to point 7
A
If there is continuity go to point 8
7
Check the continuity of the wiring connecting
the board to the actuator.
B
Otherwise restore continuity
A
The actuator malfunction has been repaired, go to
point 9.
8
Proceed to control actuator operation manually
on the bench, see B2.4.
B
The actuator cannot be repaired, replace it.
A
If absorption is very high, check and lubricate the
squeegee mount levers.
9
Check the draw of the squeegee actuator as
described in paragraph B1.1
B
If absorption is within the norm, restore the
mechanical parts.
