7. Check the voltage of the new lithium battery in ScanWin. Select the System tab at the top of the
screen; then select the Node Information tab at the right side of the screen. Look for “NVRAM
backup battery voltage.” The value displayed should be close to 3.6 volts.
Returning the Scanner to the Manufacturer
If the Scanner 1141 RTU must be returned to Cameron’s Measurement Systems Division, ship it as a
complete unit
, but remove the sealed lead acid battery from the Scanner enclosure. There is usually no
need to return the battery.
If it is not possible to return the complete unit, return the main circuit board. The main circuit board is
removed by undoing the six screws or standoffs that connect it to the base plate. NOTE: Circuit boards
should be shipped in antistatic bags, and a well-protected package.
Replacing the Sealed Lead Acid Battery
A label mounted inside the enclosure lists batteries certified for use with the Scanner 1141 (Figure 5.3).
An operator can determine which batteries are suitable for his Scanner 1141 by identifying batteries with
the proper voltage and temperature range, or by examining the order code in the Code field of the data
plate attached to the Scanner 1141. The order code for the battery is the first two-digit number following
the Scanner 1141 model. For example: if the code listed on the data plate is 1141L-XX-YY-YY… ,
“XX” is the battery order code required for replacement.
