Technical User Guide
With the function
Sensor alarm delay
, you can postpone the alarm signal so that
transient changes of the pressure level in the livestock house, e.g., when open-
ing a door, do not trigger the alarm.
The controller activates an alarm when the pressure in the livestock house
drops below or exceeds the settings of
Pressure low limit
/
Pressure high limit
.
You can connect and disconnect the alarms and set an alarm limit.
Dynamic Air
The Dynamic Air alarm is triggered in case of mechanical error. The house con-
troller triggers an alarm if the measurement of the ventilation output deviates
from the calculated ventilation requirement.
You can connect and disconnect the function.
The alarm may be due to a mechanical error in the fan, the pressure sensor or
the flap position.
Check the fan while it is running. Further troubleshooting must be carried out by
technically trained personnel.
Outlet alarms
Outlet alarms are technical alarms. The controller triggers an alarm if the flap
position of the air outlet deviates from the setting which the controller calculated
as correct.
You can connect and disconnect the alarm.
