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>.

7.10 Setting Relays
Relay Functions
Use the [Relay Setup] menu to assign a function to channel relays. The flow meter supports
two types of relay outputs, Alarm Relay and Pulse Relay. Alarm Relay outputs operate in
"fail-safe" mode. The relay(s) are energized under normal conditions - an alarm condition
causes the relay(s) to de-energize until the alarm clears. The Pulse Relay output supports
Totalizer and batch relay functions, with an output pulse width of approximately 200 ms;
maximum activation rate is 2.5 pulses per sec. If Totalizer pulses exceed this rate, excess
pulses are stored in an overflow register. This allows the relay to "catch up" when flow
decreases enough.
Note
Using the <F1> key (Totalizer clear command) also clears all channel Totalizers plus the
overflow register described in the last paragraph.
