NOTE
If the device is not configured to check for abnor-
mal process conditions using the Sampling Bands
(section 6.6.2), the Abnormal Transmission Rate
is not used and this section can be ignored.

The Abnormal Transmission Rate is identical to the Normal Transmission
Rate with one exception. The Abnormal Transmission Rate only applies
while the Transmitter is in an abnormal condition (see Section 6.6 Select-
ing the Normal Upper and Lower Values). This allows an increase or de-
crease in the frequency of information you receive depending on the oper-
ating conditions of the process being monitored.
In order to properly set the Abnormal Transmission Rate, determine how
often updates are needed from the Transmitter when the process being
monitored is operating under normal conditions. The Transmitter has a
selectable range of 1-5, 10, 15, 20, 40 seconds and 1 minute. Figure 6‑7 is
an example of how the device switches transmission rates from Normal
Transmission Rate to Abnormal Transmission Rate. Note how the first
abnormal transmission is sent immediately when the Normal Upper Value
set point is exceeded. The next transmission will then follow this immedi-
ate transmission by 10 seconds (or whatever the Abnormal Transmission
Rate is set to). The transmissions will continue at this interval until the
process value drops below the Normal Upper Value set point.
Once the process value drops below this set point, another transmission is
sent to the Base Radio. The transmissions will then be sent at the Normal
Transmission Rate of one minute (the current setting for the Normal
Transmission Rate) from the time of the last abnormal transmission.
The user should also note that the transmission time depends on the sam-
pling rate, and when the process value is sampled. If the Normal Sampling
Rate is 30 seconds, then the process value may be above the Normal Up-
per Value for up to 29 seconds before an abnormal condition is detected.
This means that the transmission could be as late as 29 seconds after the
process value exceeded the Normal Upper Value.
Once you have decided the proper time for the Abnormal Transmission
Rate, select this setting from the Transmitter or through WMT.
Follow the menu map below.

If you have the Wireless Management Toolkit software this menu option
will not be accessible via the Transmitter once the Transmitter detects
that the software is being used (See Appendix A for more details). An
explanation of how to select the Abnormal Transmission Rate using the
Wireless Management Toolkit software can be found in section 6.7.
* Indicates that Menu is Disabled if Wireless Management Toolkit is detected. (See Appendix A)
