Use and Maintenance Instructions
Below we give a description of some malfunctions that, on the basis of internal statistics, occur most
frequently and are caused by wear, exposure to particularly difficult climatic conditions or failures.
Therefore, based on the data in our possession, these are the most common cases and relative method for
identifying the fault according to the following:
1. Brush behaviour:
-
Potential fault
•
Possible solutions
Pendulum BRUSH:
1. The brush does not start:
•
No voltage supply to brush.
-
Make sure that the voltage supply is arriving.
-
Check that the differential and/or magnetothermal switches are in the correct position.
-
Check the integrity and correct connection of the supply cable and the motor cable.
•
Supply voltage too low: the display shows alarm message "2".
-
For brush with 230VAC supply, check that voltage is more than 180VAC.
-
For brush with 115VAC supply, check that voltage is more than 85VAC.
•
Tensione di rete troppo alta: il display mostra il messaggio di allarme "1".
-
Per spazzola alimentata a 230VAC verificare che la tensione di rete sia inferiore a 270VAC.
-
Per spazzola alimentata a 115VAC verificare che la tensione di rete sia inferiore a 140VAC.
•
Fuse F1 burnt out.
-
Remove voltage from brush and replace the 10A fuse F1, pressing the cap and turning
slightly anti-clockwise. Supply voltage to brush and check that the red LED DL1 lights up.
If the fuse burns immediately, the board is faulty.
•
Red LED DL1 off.
-
Check integrity of fuse and that it is inserted correctly in its housing.
-
Carry out checks as above.
•
The inclination sensor does not work for pendulum.
-
Check that the sensor is properly connected to terminals 8N, 9M, 10G as shown in Fig. B.
-
Replace the inclination sensor.
•
Faulty board.
-
Replace board.
2. The brush continues to operate:
•
Dip-switch SW1 not configured correctly.
-
Configure dip-switch SW1 as shown in Fig. B (1 ON and 2 OFF) for pendulum
•
The inclination sensor does not work for pendulum
-
Check that the sensor is mounted and locked correctly on the fastening plate.
-
Check that the sensor is properly connected to terminals 8N, 9M, 10G as shown in Fig. B.
-
Replace the inclination sensor.
