R1 (R2) TYPE: selects the type of reference measurement to drive the
relay. Possible types:
Frequency: driving frequency of the pump
▪
Power: power supplied to the pump
▪
Time: time from start
▪
Normal: achievement of normal condition
▪
Pressure: pressure read by the gauge, if present
▪
R1 (R2) SET VALUE: Sets the reference value at which the relay R1
(R2) is activated. This parameter has no effect if NORMAL (previous
parameter) is selected as SETPOINT TYPE.
R1 (R2) HISTERESYS: Sets, in percentage, the hysteresis of the relay
R1 (R2) MASK TIME: sets the masked time (in hh:mm:ss), measured
from start, within which the SETPOINT R1 (R2) is not driven even if
the threshold value has been reached. This parameter is not available
if SETPOINT TYPE is set to NORMAL
R1 (R2) OUTPUT LOGIC: Selects the control logic of the SETPOINT
output.
positive logic (the relay is energized when the measurement
▪
exceeds the reference)
negative logic (the relay is energized when the measurement is
