Replacing The System Backup Battery; Replacing The Absolute Battery - Yamaha DRCX User Manual

14-2 Replacing the System Backup Battery

If an alarm is issued indicating that the system backup battery voltage is low, replace the battery
using the procedure listed below.
(1) First, make a backup copy of all necessary data using a memory card or POPCOM software,
because that data in the controller might be lost or destroyed during battery replacement.
(2) Unplug all connectors from the controller and then remove the top cover.
(3) You can now see the control board. Remove it from the controller.
(4) The lithium battery is soldered to the control board. Use a desoldering tool or similar tool to
remove the solder and then remove the battery from the control board.
(5) Solder the new battery to the control board.
Battery product number: CR2450THE (Toshiba Battery)
(6) Install the control board back in its original position.
(7) Reattach the top cover.
(8) Initialize all data and then return the data you backed up into the controller.
Please note that the state of California USA has legal restrictions on the
handling of manganese dioxide lithium batteries. See the following website for

14-3 Replacing the Absolute Battery

The absolute battery will wear down and must be replaced. Replace the battery when its service life
has expired or when problems with backing up data occur even when the battery charge time was
long enough.
Though battery wear depends on the number of charges and the ambient temperature, both B1 type
and B2 type batteries should generally be replaced one and a half years after being connected to the
controller. Replace both batteries at the same time.
Always charge the new battery after it is installed. The battery is automatically charged while the
controller is turned on. Keep the battery charged for longer than the time listed in the table below.
Since the battery charging time does not affect robot operation, the controller can be used to perform
teaching, program editing and robot operation while the battery is still being charged.
* When the absolute battery is disconnected from the controller, an alarm (24:ABS. DATA ER-
ROR) is issued. So an alarm is always issued when the absolute battery is replaced, but this is
not an error. (An alarm "23:ABS. BAT.L-VOLTAGE" may occur in some cases.)
Absolute batteries are recycled items. Please contact our sales office for proper
disposal of used batteries.
