TEOM Continuous Particulate Monitor
The 1400A and 1400AB TEOMs can be directly connected to the WinAQMS Mini DAS via
RS232. The TEOM also has the added feature of monitoring all its internal parameters. For
example you can record the filter loading of the TEOM and hence remotely determine if the filter
needs to be changed.
TEOM Setup
For RS232 communication between the TEOM and the WinAQMS Mini DAS the TEOM has to
be in "AK Protocol" mode. If it is in AK Protocol mode the top line of the TEOM display should
read "AU" next to the filter loading.
If not, on the TEOM front panel press the RS232 button. If the Mode is not AK Protocol then
press the down arrow until the cursor is pointing to AK Protocol then press Enter.
The TEOM has a station number or address. The factory default address used by TEOM is 4
(ASCII 52). There is no need to change this. However, if you need to change the address, proceed
as follows:
1. Press Step Screen until the COM 2-Way Settings screen is displayed.
2. If RS-Para 1 is not equal to the ASCII code of the selected station number then set the
cursor against RS-Para 1 and press Edit.
3. Key in the selected ASCII number (ASCII 52 for address 4) and press Enter.
4. Press Main to exit setup.
The program register codes are listed in Appendix A in the TEOM 1400a manual.
DANI TNMH Hydrocarbons Analyser
The AQMS software supports RS232 communications with the DANI TNMH 451 & 452
Hydrocarbon analysers.
The only parameters available from the DANI are MET (CH4 or Methane), NMHC
(Non Methane Hydrocarbons) and THC (Total Hydrocarbons).
All readings are in ppm.
The default baud rate is 9600 baud.
There is no address or physical input number.
If there is a flame fail condition or other alarm condition, there will be data but it will
be marked as having an instrument fault status.
When the DANI switches from MR to LINE measure and back again (every 3
minutes), AQMS will not read data for a short time (approx 30 seconds) to allow for
the reading to stabilise.
When the DANI switches from MR to LINE measure a back again (every 3 minutes),
WinAQMS Mini DAS will not be able to read a new data value for a short time but
instead will use the last data value before the DANI switched to the LINE measure.
When configuring WinAQMS Mini DAS you should set the "% Samples for valid
report" to no more than "70%" in the System Parameters.
