Section III – Run Mode
Run Mode
The “RUN” Mode is the normal operator-controlled mode of operation where a batch volumes are displayed.
All control operations can be performed either locally through the keypad or through communications. The opera-
tion described in this section assumes that the microFlow.net Gas is being operated locally through the keypad. For
information on operating through communications, refer to the microFlow.net Gas Communications and Reference
Manuals.
Overview
The “RUN” Mode permits the operator to observe the dynamic variables such as flow rate, temperature, volume
correction factors, and transaction (batch) totals.
Resetting/Starting a New Batch
Batching in the microFlow.net Gas allows the operator to reset or start whenever needed. Batching will not stop flow
and restart when reset, but will “on the fly” allow for a new batch totalization while allowing for flow rate control. The
following steps are required to reset a batch:
Resetting a Batch
Step 1
Press the “ENTER” key from the “RUN” Mode.
Step 2
The Main Menu will appear. With the cursor (arrow) beside the “RESET BATCH” press “ENTER”.
Step 3
When prompted for the passcode, enter the programmed passcode set in the programming.
Step 4
A new batch will now begin as the “RUN MODE” totalizers reset to zero (0) and begin incrementing as flow is present.
Stopping the Flow Using the Keypad
The only way to stop the flow locally at the keypad using the digital control valve, is to enter the program mode and
set the flow rate to zero (0). This operation is not practiced in normal pipeline applications, but is available if needed.
To prevent the operator from performing this operation the flow rate parameter is under passcode protection.
Keypad Functions
The push-buttons on the keypad perform the following preset functions in the Run Mode:
0 – 9 Used for entering numeric data.
h Used to navigate backwards through the menu to get into the displays. When in the
dynamic displays, the up arrow also moves backward through displays.
f Once in the dynamic displays, this works like the up and down arrow to move forward
through the displays.
g Once in the dynamic displays, this works like the down arrow to move forward through
the displays.
i Used to navigate forward through the menu to get into the displays. When in the dynamic
displays, the down arrow also moves forward through the displays.
CLEAR Used to exit the Dynamic Display.
ENTER
Used to enter the Dynamic Display menu and to enter the dynamic displays from the menu.
