The instrument is supplied ready for the following applications:
Models with temperature probes (NTC, Pt100,Thermocouples): control of ovens,
burners, heating systems and in general low temperature alarms.
Models for humidity probes: control of humidifiers and in general low humidity alarms.
Models for pressure probes: control of evaporators and in general low pressure alarms.
As shown in the picture, the main parameters in this function mode are Set Point (St1) and
differential (P1).For the standard function, which corresponds to Reverse action, the
regulator energizes the outputs only if the controlled parameter decreases from the
Set-point value. Once fixed at the desired Set Point (St1), the outputs will be energized one
by one as the parameter deviates from St1.As shown in the picture, in models with more
outputs, the activation of relays is equally distributed within the differential. When the
controlled parameter is equal to/lower than St1-P1, all outputs will energize.Viceversa,
starting from values lower than St1, if the parameter starts to increase any active relay will
be de-activated as approaching St1.When the St1 value is reached, all outputs will be
disenergized.
The REVERSE led will flash with a number of pulses equal to the activated outputs.
