92 Faults and warnings
Feeder operation will be interrupted. Make sure that the end user provides the calves with feed
using an alternative method as long as feed operation is interrupted.
You can correct the fault as follows:
1. Confirm Fault, water shortage by choosing .
2. Confirm Boiler water start? by choosing .
3. Check that the water jet hits the rod or point electrode (see 9.5.3 "Checking sensors" - 110).
4. Check the water supply to the automatic feeder.
5. Check whether deposits such as calcium have formed on the electrodes.
6. Confirm Delete fault? by choosing when you have fixed the fault.
DANGER!
Fatal electric shock.
The electrical components of the automatic feeder are live.
► Always switch off the automatic feeder firstly with the Main switch and then disconnect the
power plug before changing the response sensitivity of the electrode.
Check and change the response sensitivity of the electrode.
1. Navigate via > Diagnostics > Sensors to the Elec. point or Elec. rod sub-menu.
2. In the right-hand column, check the status (free or covered).
3. Confirm Elec. point or Elec. rod with .
3.1. In the Status menu, check the status (free or covered).
3.2. Confirm Bo. water start? by choosing .
The electrode will be triggered if water is dispensed into the mixer beaker.
3.3. Confirm Mixer: draining? by choosing , to pump out the liquid again.
4. Visually inspect the electrode.
4.1. If the electrode reports that it is covered although it is actually free, the response sen-
sitivity of the electrode is too high.
4.2. Reduce the response sensitivity of the electrode by rotating the potentiometer (see
machine circuit diagram in the appendix) counterclockwise on the main board.
4.3. If the electrode reports that it is free although it is actually covered, the response sen-
sitivity of the electrode is too low.
4.4. Increase the response sensitivity of the electrode by rotating the potentiometer (see
machine circuit diagram in the appendix) clockwise on the main board.
5. Confirm Delete fault? by choosing when you have fixed the fault.
