Use and Maintenance Instructions
In the case of the pendulum brush, this is connected to a 3-wire inclination sensor.
When the device is activated, the SL49 starts a brush rotation procedure that lasts for a set time
of 90 seconds. The end of each cycle is followed by a pause of about 4 seconds; when the device
is activated again, the motor starts to turn in the opposite direction to that of the previous cycle in
order to use the brush evenly. The display shows the letters "R" and "L" to indicate the sense of
rotation.
Control of current
The device checks the current absorbed by the motor to establish whether the brush is operating
correctly. Every time the current exceeds the threshold set by the Trimmer R22, the brush inverts
rotation (motor block/failure condition); if this situation is repeated more than 5 times at intervals
of less than 6 seconds, the SL49 enters a condition of alarm identified by message "5" on the
display.
The same situation could occur when the board does not detect variations of the current when
passing from motor off to motor on (situation of disconnected/burnt out motor or board failure).
In this case, however, the system enters the condition of alarm immediately without waiting for
the event to be repeated more than 5 times and the display shows message "4". If one of these
two alarms occur, the SL49 remains in the condition for about 4 minutes, then returns to normal
operation.
Overvoltage and undervoltage control
The SL49 board constantly monitors the voltage supply (230/115V) and switches off the brush if
this reaches values that could damage the electronic board or the motor. These conditions of alarm
are identified by the messages "1" and "2" on the display; the SL49 remains in one of these two
conditions as long as the alarm persists.
Overheating control
The SL49 board constantly monitors the temperature inside the container, switching off the brush
if it exceeds 75°C; the display shows message "3" and the SL49 remains in this condition as long
as the alarm persists.
