USING THE MACHINE

Inspection and controls before use:
Use:
The cattle brush has been designed and produced for use as a system for cleaning the coat of the animal (cows). IT
MUST NOT BE USED for any purpose other than cleaning the coat of cattle.
Activation:
• when the animal pushes against the brush, a microswitch starts to turn the roller which automatically proceeds to
clean the animal without requiring assistance by staff.
• By means of the start motor contact, the board controls the start and finish of a work cycle. When the device is
started, the electronic board begins a brush rotation procedure which lasts 1 minute. When the device is started
again, the motor turns in the opposite direction to the previous cycle so the brush is used evenly.

ELECTRONIC SYSTEM

FUNCTIONS

The SL49 board manages the functions of electric brushes for farmed cattle, controlling the start motor contact, the
working 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.
Main features
· Motor protection with 10A fuse.
· Motor start by means of electronic commutators (Triac).
· Messages signalled on one-digit display.
· Monitored power supply.
Normal functions
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 finish of a work cycle. It can be connected to a
normally open contact or normally closed using Dip Switch SW1. In the case of the oscillating brush, this is connec-
ted 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" 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 situation could occur when the board does not detect variations of the current, 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 occur, the SL49 remains in the condition for about 4 minutes, then returns to normal
functions.
