Accu-Wave Chapter 4 Set up Additional Measurements
TN Technologies 4-9
Set Up Alarm…
The primary measurement is automatically assigned to measurement 1; however, signal
strength, volume, and other measurements are not assigned a measurement number by
default. Therefore, volume, signal strength, and other measurements are not available to
drive the current output, alarms, or relays until you assign them to a measurement number
using the “Set up additional measurements” menu.
Setting up an alarm for a measurement other than the primary measurement is a three step
process. First, set up the measurement using the “Assign and set up measurement #”
menus. Second, assign an alarm to the measurement using the “Assign alarms to
measurements” menu items as described in “Set Up Fault Alarms or Change Process
Alarm” on page 6-3. By default, all alarms are assigned to measurement 1, the primary
measurement. Third, return to the measurement setup menus which will now read “Modify
set up of measurement #,” to set up the alarm.
After assigning one or more alarms to a measurement, the “Set up Alarm” menu items will
be displayed under the appropriate “Modify setup of measurement #” menu under the “Set
up additional measurements” menu, allowing you to set up or modify the alarms. For
example, if you assign alarms 5 and 6 to measurement 3, setup menu items for those
alarms will be displayed when you set up or modify measurement 3.
For details on setting up alarms and a description of the alarm parameters (set point, clear
point, dead band, etc.), refer to “How to Set up Alarms” on page 3-6 which describes
alarm setup for the primary measurement. The alarm setup procedure for other
measurements is the same as for the primary measurement.
