TYPE 8
Input of sensors, outlet by relay with modulation
of the time of activation proportional to the changes of
the sensors.
The
programme
proportional band and a maximum and minimum
percentage of outlet.
When the value of the sensor is higher than the
reference, the outlet increases proportionally from the
minimum to the maximum, obtaining this last one when
the
sensor reaches the value of reference plus the
programmed proportional band.
The value of time, called "cycle of modulation",
corresponds to the 100% of the time of activation of
outlet. If the value of proportion decreases, the outlet
will be activated for as long as it corresponds from the
percentage of the cycle of modulation a nd the rest of
the proportion will not be activated. This will be
repeated once the time of the cycle of modulation is
finished.
Example: proportional ventilation.
