by pressing the “Page Up” and “Page Down” keys until the desired mode
appears. Press ENTER to move the highlight bar to the “SEND THIS
COMMAND” line then press ENTER to send the mode change request.
The highlight bar will move back to the COMMAND MODE line.
The upper half of the screen displays and continuously updates the
Instantaneous Flow Volume, the mode of the TIE, and the Multi I/O
output mode. This allows the operator to monitor these parameters while
the system is executing the mode change request.
The TIE and Multi I/O respond differently to each mode change request.
Also the system reacts differently when entering and exiting certain
modes. Refer to Table 6-5, Mode Change Request Table, for more
information.

When the TIE sees a NORMAL mode change
request it goes into a NORMAL-ACQUIRE
mode at the beginning of the next integration
period and sends its mode out on the network.
This mode will last for the number of
integration periods specified in the averager. At
the end of NORMAL-ACQUIRE the TIE will
indicate NORMAL mode. The TIE will
continue in this mode until it gets another mode
change request. The analog outputs will trend from whatever mode data
they were displaying before, to the data that they are
configured for during the NORMAL mode. The MIO
mode follows the TIE mode not the request. The TIE
changes modes based on the request. At the end of the
TIE’s first integration period in NORMAL-ACQUIRE the
MIO will update its mode and relay statuses to match the
NORMAL-ACQUIRE mode. Likewise at the end of the
first period of NORMAL data the MIO will update its
mode and relay statuses to match. The MIO mode always
lags the TIE mode by one period because data is sent at the
end of the integration period.
Note : Data is not considered valid emission data during
the NORMAL-ACQUIRE mode.
