Application example:
The temperature and humidity of an environmental chamber are controlled by
two loops. Loop1 uses a heater to increase the temperature and cooling coil
to lower the temperature. Loop2 uses a solenoid to control water to flow to an
atomizer to raise the humidity and a dehumidification coil to lower the humidity.
To minimize wear on the compressor and use of electricity, the compressor is
turned OFF and ON by the controller’s output for compressor control.
- The signals from the temperatures and humidity loops’ determine when
the temperature, humidity loops need the compressor to be on.
- The signal from OUT signals when to turn on the compressor.
- To save power and extend the life of the compressor, it is desirable for
the compressor to be off when it is not needed. The need for the
compressor is anticipated by monitoring the inputs.
- Delay times could be set.
- Enter names for inputs, outputs to make the application easier to
understand.
- Sensors calibration is possible.
- Set the hysteresis parameters long enough to protect the compressor
from too much cycling, but short enough to allow the compressor to turn
OFF between uses.
