5. General Maintenance
Safety and Installation (T, VT / EPSON RC+ 7.0) Rev.15 105
The life span of the lithium battery varies depending on the energizing hours and
installation environment of the Manipulator. It is about 7 years as a rough guide
(when the Controller is connected to power for 8 hours a day). When the
Manipulator is not connected to power, the battery consumption will significantly
increase compared to when the Manipulator is energized. If warnings of voltage
reduction occur, replace the lithium battery even if it has not reached the above
product life.
For the EPSON RC+ 7.0 the recommended replacement time for the battery can be
checked in the [Maintenance] dialog box.
For details, refer to the following manual.
T series Manipulator Manual: Maintenance 4. Alarm
VT series Manipulator Manual: Maintenance 4. Alarm
The battery may run out if it passes the recommended replacement time.
If no warnings of voltage reduction occur, the calibration for all joints is not
necessary. You need to perform calibration if the position moves from the
originals after replaced the battery.
Be sure to use the designated lithium battery.
Be sure to set the correct polar when installing the battery.
