Use and Maintenance Instructions
Below we give a description of some malfunctions that, on the basis of internal statistics, occur most
frequently and 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 methods
for identifying the fault according to the following:
1. Brush behaviour:
•
Potential fault
-
Possible solutions
Double 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 motor
•
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.
•
Supply voltage too high: the display shows alarm message "1".
-
For brush with 230VAC supply, check that voltage is less than 270VAC.
-
For brush with 115VAC supply, check that voltage is less than 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.
•
Limit switch does not work
-
Make sure that when moving the brush the limit switch is released and pressed correctly.
-
Check that the limit switch is positioned correctly.
-
Check that the limit switch is connected correctly to terminals 9M and 10G as shown in Fig. A.
-
Replace the limit switch.
•
Faulty board.
-
Replace board.
2. The brush continues to function:
•
Dip-switch SW1 not configured correctly.
-
Configure the dip-switch SW1 as shown in Fig. A (1 and 2 OFF).
•
The start motor limit switch does not work
