Output pressure DECREASING
(Graph no.4):
With output pressure probe values equal or higher than point (D), you will have a 10V analogue output.
Between points (D) and (E), the analogue output will have a value proportional to the value of the output
pressure probe starting from the maximum value of 10V up to the minimum value of the (iMv) parameter.
With values of the output pressure probe lower than point (E) and higher than point (F), you will have an
analogue output equal to the minimum value of the (iMv) parameter.
The analogue output of the adjuster will be 0V for output pressure probe less or equal to point (F)
representing the "SET point" value.
Digital output no.1 represents "the condenser fans inverter activation" and is ON for pressure values higher
than or equal to the set point and OFF for lower values.
CONTROL IN THE EVENT OF ALARMS
With the output no.1 alarm input activated, the analogue input will be immediately brought to 0V and the
digital output no.1 will be opened after (inverter-enabling is removed).
The relative alarm (EV1) will also be shown on the display.
