Not enough water alarm
The alarm is triggered if the water consumption measured by a water meter is
too low during a given period of time.
It is recommended to set this alarm to 1,0 l/min. and a monitoring time to 30
minutes. This means that an alarm will be generated if consumption is lower
than 30 litres each half hour.
Too much water alarm
The alarm is triggered if the water consumption measured by a water meter is
too high in a given period.
Depending on the capacity of the water supply, the system can supply a cer-
tain quantity of water per unit of time.
The alarm is triggered when the system has operated at maximum output for
too long.
If a water relay is installed, the water will be closed at excessive water con-
sumption.
Guidelines for alarm limit settings
:
Measure how much water runs in one minute on the current water meter. Set
the alarm limit for 1 litre less than that measured. Set the monitoring time to 30
minutes.
Start alarm day
In the event of major changes to the number of animals in the house, at least
26 hours should pass before the house controller can trigger the alarm.
In order to avoid triggering false alarms, you can indicate how many days
should pass before the house controller triggers a water alarm.

Figure 5: Example of minimum and maximum water alarm
The house controller triggers an alarm when the limit for maximum water consumption is exceeded or the con-
sumption is below the limit for minimum water consumption.
There may be various reasons for the fluctuation in the animals’ water consumption that will all trigger an
alarm. For example, an alarm may be triggered due to stocking more animals or the slaughter of some an-
imals, an outbreak of disease in the livestock or a rupture in the water pipe.
6.3.5 Auxiliary alarms
It is possible to create a number of auxiliary alarms. For example, the controller may give an alarm from a con-
nected motor controller, a water pump or other equipment.
The alarms are set up in the menu
