4.3.6.8 CONCENTRATION OUT Connector
A BNC female connector that provides a precision analog voltage from 0 to
10.000 V into a 2 K
Ω load that is proportional to either the concentration or
frequency shift. It operates with 15 bit equivalent resolution, monotonic to 1 LSB
4 CONCENTRATION INput
function
0 = ignore,
1 = control to target concentration equals
where:
input voltage range is set by SW-7
max = value of parameter
MAX INPUT (USER#5)
min = value of parameter
MIN INPUT (USER#6)
diff = (max-min)
5 Control Dilution Flow 0 = ignore
1 = maintain Dilution Flow as (Total Flow
- Bubbler Flow) any time the controller is
on and the Control or Bypass command
has been given, unless Input #3 (STOP)
of the system I/O is active. Used in
Concentration Control configuration only.
6 spare
7 Input Voltage Range 0 = 0-10 volts
1 = 0-5 volts
Selects input voltage range for both
CONTROL INput BNC (see section
4.3.6.10 on page 4-28) and the optional
Analog I/O accessory’s input; see section
Table 3-3 on page 3-13 for Bulk Flow or
section Table 3-5 on page 3-19 for
Concentration.
8 Control Mode 0 = Concentration Control configuration
(standard)
1 = Bulk Flow Control configuration;
requires optional Analog I/O card.
