Monitoring The Brush Resistance; Setting The Cycle Time; Explanation Of The Display Indications - Kerbl MaxiSwing Instrucciones De Uso

6.3.1 Monitoring the brush resistance

The unit monitors the current used by the motor and therefore checks the correct functioning of the cattle brush. If the gear motor is placed under
too much strain, the brushes stand still and then move in the opposite direction. This can occur if the animals lean to far too one side or if a tail
gets wound up in the mechanism.
If this event is repeated several times without the unit having run properly in between, the unit first goes into an alarm state for a few minutes
and does not start during this time. If the load on the motor is not lower even after this pause, then the fault message "A03" is triggered after
further load cut-offs and the unit no longer starts.

6.3.2 Setting the cycle time

The cycle time is set at the factory to 60 seconds. If necessary, this can be adjusted using the dip switch element on the circuit board
(Fig. 8 - item 1) to a value between 7.5 and 300 seconds. The cycle time may only be readjusted after consultation with Kerbl Service.

Once the unit has been restarted (connected to the power supply), the dip switch changes will take effect and the settings will be briefly shown
on the display.
