Programming and control 45
4.6.1.1 Rationed mode / ad lib mode
The automatic feeder operates in rationed mode by default, but can also be switched to ad lib
mode.
•In rationed mode, the feeder uses animal identification, i.e., the animals are individually fed
rationed amounts. Rationed mode is the default setting.
•In ad lib mode the feeder does not use animal identification. The automatic reading in of
transmitter numbers is therefore not possible in this operating mode. During feeder opera-
tion, a portion is always prepared as soon as the rod electrode in the mixer beaker is free
(mixer empty). If a valve unit (optional) is fitted, the feeding box valves are continually open.
WARNING!
Beware of the risk of burns on feeding box valves (optional).
During prolonged ad lib mode, any feeding box valves that are fitted become hot. You, or the
end user, can burn your fingers or hand when touching these valves.
► For this reason, push the suction hose directly onto the mixer beaker spout and disconnect
the connector from the feeding box valve.

Cleaning agent that enters the feed can be hazardous to the health of calves.
► Therefore, always disable all time-controlled cleaning menus and calibrations during ad lib
mode.
You set the operating mode as follows:
1. Navigate via > Device data > Operating modes to the Ad lib sub-menu.
2. Select the option yes in the selection box to activate ad lib mode. Choose no to select ra-
tioned mode.
3. Configure the following lines or, as the case may be, the values for the Feed concentration
and the additive dosage.
