Expert-32P rev.11
The Expert-32P is an electronic device used for environmental control in
livestock buildings. It allows the user to maintain a specified target
temperature by controlling the operation of ventilation and heating
equipment. Eight heater stages, 10 on-off fan stages, 2 cooling outputs
vent doors, tunnel curtains and 2 clock outputs can be connected to the
controller. Fan stages can be configured to activate cooling systems in
timer mode. In all, the Expert-32P provides up to 32 relay outputs. In
addition, if vent doors are not used, up to 12 PF-6 air inlet controllers
can be connected to the unit.
The main features of the Expert-32P are as follows:
LCD DISPLAY
An LCD display provides an efficient interface for displaying, monitoring
and adjusting parameter values.
PILOT LIGHTS
Pilot lights indicating the state of outputs allow the user to monitor the
operation of the system without having to enter the building.
MINIMUM VENTILATION CYCLE
When ventilation is not required for reducing room temperature, the first
and second fan stages can be operated either continuously or intermit-
tently to reduce the level of humidity and supply oxygen to the room.
TEMPERATURE AND MINIMUM VENTILATION CURVES
The controller can be set to automatically change the temperature set
point and the minimum ventilation cycle over a given period of time in
accordance with the user's requirements by specifying a temperature
curve and a minimum ventilation cycle curve with up to ten different
points each.
PROBE READINGS RECORDED FOR PAST DAYS
Minimum and maximum readings from temperature, humidity and static
pressure probes are recorded for the current day and the previous six
days.
