DESCRIPTION
0-99
Gauge gas load type. The value is divided by 10
(entering 12 the controller will apply 1.2)
Enter here the correction factor for gas (necessary
only if gauge is connected).
0-10000
Setpoint 1 value. Enter here the threshold value for
the R1 output, valid only if B
Buffer Offset-21 is equal to 0,1,2 or 3.
0-30000
Setpoint 1 Mask Time. Set here the time, measured
from the start pump event, while the R1 output is
masked (not activated)
0-10000
Setpoint 2 value. Enter here the threshold value for
the R2 output, valid only if B
Buffer Offset-21 is equal to 0,1,2 or 3.
0-30000
Setpoint 2 Mask Time. Set here the time, measured
from the start pump event, while the R2 output is
masked (not activated)
0-30000
Vent Valve Opening Delay.
Set the delay time between the stop command and
vent opening. Valid only in "purge/vent auto mode"
(Parameter Buffer, Offset 20, B
(the valve will never open).
0-30000
Vent Valve Open Time. Set how long the vent will
remain open, then both purge and vent will be
closed. Valid only in "purge/vent auto mode"
(Parameter Buffer, Offset 20, B
(the valve remain open till next start command).
1-99
Setpoint 1 Hysteresis. Set the Setpoint1 hysteresis
around the nominal value
1-99
Setpoint 2 Hysteresis. Set the Setpoint2 hysteresis
around the nominal value
