6.12 Configuring Smart Meter Using Pushbuttons
Background
The local smart meter can be set to show the PV out in engineering units
that are appropriate for your process application. You can select an
available engineering unit or enter a custom one including upper and
lower display limit settings for the local smart meter’s digital readout
using buttons on the face of the meter.
Using the Smart
Meter
Follow these guidelines when configuring the local smart meter:
• If you initiate an SFC command at the same time a button is pressed
on the local smart meter, the local smart meter will respond to the
command it receives last. In other words, the last command wins.
•
In most cases, you can press and release a button for one-shot
operation, or press and hold a button for continuous, 1/2 second,
repetitive operation.
•
Active setup field will begin to flash at one second rate if next action
is not initiated within one second. And, if no action is taken within
30 seconds, the setup function will time out and the meter will return
to its previous state.
Table 31 shows an illustration of the local smart meter and a description
of the pushbuttons on the meter face.
