10.3. Analyser states
The IO module, of the analyser, can read out the status of the analyser. To set this
feature, open the path:
E
XTRAS
/ A
NALOG OUTPUT DETAILS
(see pictures below).
Each 1 mA steps represent a function. The chart below shows the different states:
# mA-Signal Function
0 4,0 mA Power-On / self test
1 5,0 mA Measuring sample point 1
2 6,0 mA Measuring sample point 2
3 7,0 mA Measuring sample point 3
4 8,0 mA Measuring sample point 4
5 9,0 mA Measuring sample point 5
6 10,0 mA Measuring sample point 6
7 11,0 mA Measuring sample point 7
8 12,0 mA Measuring sample point 8
9 13,0 mA Measuring sample point 9
10 14,0 mA Measuring sample point 10
11 15,0 mA Zeroing
12 16,0 mA Gas sampling (from any sample point)
13
17,0 mA System Alarm (measurement halted)
14 18,0 mA Manual calibration in progress
15 19,0 mA Automatic calibration in progress
16 20,0 mA Stand-By
10.4. Configuration of the external control (Option: IO module)
This feature requires an I/O module (optional) and the function must be activated
.
This feature can be used for the external control of the analyser. With the help of
the external control follow operations can be done:
•
Externally controlled sampling point selection,
•
Stand-by.
The commands will be given by a 4-bit binary number, which will be built through
four external signals. The pins for the signal are shown in the sketch below. It exists
two different types to set the four pins:
•
Potential free relay contacts.
•
4-20 mA signal inputs.
