Functions
7.4 Operation Adjust Menu Settings
To edit Deadband default setting (0.000):
1. From the [Dual Path Flow] menu scroll to the [Operation Adjust] menu and press <Right
Arrow>.
2. Scroll to the [Energy Deadband] or [Deadband Control] menu.
3. Press <Right Arrow>to enable numeric entry.
4. Use the numeric keys to type in the desired rate (using selected flow rate units).
5. To register the new value press <ENTER>.
Memory/Fault Set
Certain situations will interrupt data production (e.g., an empty pipe or excessive aeration).
Use Memory/Fault Set to select the flow meter response to such an interruption. The Fault
setting (default) will zero the flow rate output and declare an alarm on a flow display screen,
Datalogger report and an assigned relay output.
For some applications, occasional temporary Fault conditions may be a normal part of the
process and would not require an alarm response. The flow meter offers a Memory operating
mode to support such an application. Memory Mode suspends the flow meter Fault response
by preventing the flow outputs from dropping to zero for the interval specified in the Memory
Delay menu cell. During the Memory duration, the flow meter will maintain the last valid flow
reading measured before the onset of the fault condition. The default Memory Delay is 60
seconds. You may select any duration from 3 to 604,800 seconds (one week).
Selecting Memory Mode
1. From the [Dual Path Flow] menu scroll to the [Operation Adjust] menu and press <Right
Arrow>.
2. Scroll to the [Memory/Fault Set] and press <Right Arrow> to access option list.
3. Move the cursor down to [Memory] by pressing <Up/Down Arrow>.
4. To make selection press <ENTER>.
5. This moves the highlight to [Memory Delay (s)].
Memory Delay (s)
Selecting [Memory Delay <s>] activates the suppressed [Memory Delay] menu cell. It allows
you to specify the number of seconds that the flow meter maintains its last valid flow reading.
When the memory delay expires, it triggers the fault alarm response described previously.
Setting Memory Delay
1. To enable numeric entry press <Right Arrow>.
2. Use the number keys to type the delay in seconds.
3. To register the new value press <ENTER>.
