Main Features - AGRICOW Doppia Mode D'emploi

The SL49 board manages the operation of electric brushes for farmed cattle, controlling the start
motor contact, the operation time, the direction of rotation and the force applied to the brush itself. It
supports monophase 230VAC motors (1HP max) for the standard version and 115VAC (0.5HP max)
for version "A". A one-digit display signals some messages, such as the motor's sense of rotation
or any alarms detected.

Normal OPERATION
When the motor is at a standstill awaiting a work cycle, the dot on the display flashes to indicate
that the board is active.
By means of the start motor contact the board controls the start and f the end of a work cycle.
The brush is connected to a limit switch pizzato using Dip Switch SW1.
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" or "L" to indicate the sense of rotation.
Control of current
The device checks the current absorbed by the motor to establish if the brush is functioning 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 the message "5" on the display.
The same happens in case of voltage fluctuations are not detectable by the electric passing from
motor off to motor on (situation of motor disconnected/burnt out 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 are met,
the SL49 remains in the condition for about 4 minutes before coming back to its normal functions.
