3.2 Charger unit
Once pre-programmed, the barn cleaner recharges itself at the
charger unit (figure 3 4).
The charger unit can be fitted in the cowshed in two ways:
• wall-mounted
• floor-mounted
A programmed route lets the barn cleaner get back to the charger unit.
The charger unit is also the starting and finishing point for all routes.
The 230V power supply must come into the charger unit from above.
The battery charger electrodes (at the bottom of the charger unit) are
then wired up to supply 12V.
3.3 Battery charger
The TBC500 batter charger (figure 3 1) is enclosed behind the cover
at the top of the charger unit. The batter charger can be left
permanently connected to the mains voltage and to the barn cleaner,
which keeps the battery in good condition.
NOTE
• There is only a voltage across the electrodes during the
charging process, when the barn cleaner is at the charging unit.
The battery charger continuously checks the voltage of the battery.
This is kept to the correct voltage automatically. This means that it is
not possible to overcharge the battery.
3.3.1 Battery charger LED indicators
There are a number of LED indicators on the battery charger (figure 3 5). The meaning of the LEDs is as follows:
• Power LED (green): charger is connected to the lighting
ring main (normal status)
• Charge LED (orange): charger is recharging the battery;
the intensity indicates the charging current
• Error LED (red): connection are back to front
The LEDs can be seen through a cut-away at the upper right
of the charger unit (figure 3 4).
