Range
0-99 Setpoint 2 Pressure Value Mantissa.
Set the mantissa of the exponential value of the R2 setpoint
(format X.XE-XX) when it is used for pressure monitoring
(Parameter Buffer, Offset 21, B3-5 = 4). The value set here is
divided by 10, that means 11 = 1.1
-10 - +10 Setpoint 2 Pressure Value Exponent.
Set the exponent of the exponential value of the R2 setpoint
(format X.XE-XX) when it is used for pressure monitoring
(Parameter Buffer, Offset 21, B3-5 = 4).
B = Stop Speed Reading.
0
This function measures the pump speed after a stop
command.
0 = Off
1 = On
B = Active Stop.
1
This function brakes the pump after a stop command, by using
the motor as a generator.
0 = Off
1 = On
B - Reserved
2
B = Start/Stop/Interlock Mode.
3-4
Change the logic of Start/Stop and Interlock inputs. Ask to
Agilent personnel for this option
B = Vent & Purge Auto/Man
0
0 = Auto (the controller drives purge and vent valves
automatically)
1 = Manual (the user can command the valves
by serial line or profibus)
B1 = Gas Load Type. Select here the gas load
0 = Ar
1 = N
2
B = Interlock Type
2
0 = continuos (the interlock must be always present to run the
pump)
1 = at start (the interlock must be present only at start
command)
B = Setpoint R1 Logic
3
0 = active close (NO)
1 = active open (NC)
