•
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 is not available if TIME or 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 below the reference)
This parameter is not available if SETPOINT TYPE
is set to TIME or NORMAL.

PRESSURE UNIT:
selects the unit of
measurement of the pressure used to show this on
the display, for display on the serial line and for
setting of the setpoint and autopressure
thresholds. Possible options:
-
mbar
-
Pascal
-
Torr
•
GAS CORRECTION:
sets the conversion factor of
the pressure measurement in the case in which the
process gas is not nitrogen. The pressure
indicated by the instrument is equal to:
P indicated = P measured x Gas correction / 10
