(default) will zero the flow rate output and declare an alarm on a flow display screen, Datalog-
ger 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 system offers a Memory operating
mode to support such an application. Memory Mode suspends the system’s 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 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).
To select Memory Mode:
To access the [Memory/Fault Set] option list press
Move the cursor down to [Memory] by pressing
To make selection press
This moves the highlight to [Memory Delay (sec)].
Memory Delay (sec)
Selecting [Memory] activates the suppressed [Memory Delay] menu cell. It allows you to specify
the number of seconds that the meter maintains its last valid flow reading. When the memory
delay expires, it triggers the fault alarm response described previously.
To specify the Memory delay:
To enable numeric entry press
Use the number keys to type the delay in seconds.
To register the new value press
2.6 THE FLOW/TOTAL UNITS MENU
The Flow/Total Units menu is available after selecting a meter type and measurement
channel. Use the Flow/Total Units menu to select energy and volumetric flow units and an
associated time base for the energy and flow rate and total outputs. After making your selec-
tions, a view-only menu cell shows the resultant scaling. Another menu cell lets you adjust the
output resolution by selecting a display range.
This system provides three totalizer display modes:
POSFLOW Positive (forward) energy/flow total only
NEGFLOW Negative (reverse) energy/flow total only
NETFLOW The net of the Positive and Negative energy/flow (default)
