When Changing
Batteries
Once your CPU has been commissioned and is running, maintain power to the
module whenever you change the batteries.
Unless you save to flash, if you change the batteries while the power is OFF, you
will have to reload your user logic program from the original files.
Removing and
Replacing
Batteries
Battery maintenance should be performed only by qualified personnel according to
the following illustration.
Monitor the
Battery Because a Momentum CPU assembly is designed to be installed in a cabinet
where it cannot be seen at all times, no LED was created to monitor battery health.
We recommend that you reserve a battery coil in your programming p ane l soft ware
configuration and use it to monitor the health of your battery and report the need for
replacement prior to battery failure (refer to
Reserving and Monitoring a Battery
Coil
on page 224 for Modsoft or
Reserving and Monitoring a Battery Coil
on page
328 for Concept).
