Battery Installation and Replacement Considerations
The following procedure describes the installation of a battery.
Step
Action
1
Remove the insulating strip from the plus (+) pole of the battery before inserting it into the module. This strip is used to insulate the battery when on the shelf.
Note: The battery installed in the module, when shipped, has the insulating strip in place. Remove this strip and re-install the battery before operation.
2
When single battery backup is required, install the battery in Battery Slot 1. The circuitry is designed so Battery 1 supplies the current until it is used up. Battery 2 (when installed) then assumes the load requirement without interruption. Battery status is indicated via LEDs and status bytes.
3
When the controller is in operation, the batteries can be replaced at any time.
Note: When the controller is powered OFF, battery replacement can be done without RAM loss only when a second functioning battery is installed.
