How To Enable And Disable A Measurement Channel - Siemens SITRANS FUS1020 Manual

Section 6
The first selection on the list is the currently active Site Setup. The system will be ready for operation
after you install the transducers and make the required hardware connections. Note that the installed
transducers must comply with the recalled site parameters.
To recall a Saved Site Setup:
(Where a visual of a key is shown, this means press that key on a PC or use the KeyPad.)
To access the list of saved site names press the <Right Arrow>.
To move the cursor to the Site Name press the <Down Arrow>.
Press <ENTER>. This triggers a pop-up window that asks if you intend to use the original
transducer position (recommended). This means that you have to remount the transducers
exactly as they were in the previous installation.
If you cannot recreate the original transducer installation, then press <Down Arrow> to change the pop-
up list from [Original] to [New].
Press <ENTER>. This disables the measurement channel until you repeat the Pick/Install Transducer
routine.

6.1.2 HOW TO ENABLE AND DISABLE A MEASUREMENT CHANNEL

The flow computer disables a measurement channel until the completion of the required Site Setup
entries and the transducer installation procedure. The meter enables the measurement channel auto-
matically after it receives all required site data and completes the transducer install routine. (The [Site
Enable] menu cell allows you to disable or enable a measurement channel after there has been a
successful transducer install).
The system does not require your presence for routine operation. If a fault condition (e.g., an empty
pipe) disrupts operation, the system will recover automatically after the fault clears. Use Channel En-
able [No] to turn off a channel that is currently unused but active; for example, if the transducers have
been removed for servicing.
To disable a channel that is operating:
To access the [Channel Enable] option list press the <Right Arrow>.
Move the cursor to [No] by pressing the <Up/Down Arrows>.
To disable the measurement channel press <ENTER>.
To enable a channel:
To access the [Channel Enable] option list press the <Right Arrow>.
Move the cursor to [Yes] by pressing the <Up/Down Arrows>.
To enable the measurement channel press <ENTER>.
