(7) Attach and tighten the mounting screws for the front panel.
(8) Confirm that the cables are connected to 1CN and 2CN, and then turn ON the
external power supply to the BAT Module.
(9) Check the operation of the indicators and output signals as follows:
• Indicators
The POWER indicator should be lit and the ALARM1 and ALARM2 indicators
should not be lit.
• Output Signals
The ALM1 and ALM2 signals ON when the PON signal turns ON.
Note If the POWER indicator is not lit or either one of or both of the ALARM1 and ALARM2 indica-
tors are lit, an error has occurred. Repeat the procedure from the begging of the battery re-
placement procedure.
Possible Errors: Either 1) the lithium battery is not connected properly, or 2) the external
power supply/external I/O connector (1CN) is not connected properly or has a broken wire.
(10)As long as no errors have occurred, this completes the battery replacement pro-
cedure. Turn ON the power supply to the system.
Caution Do not charge the lithium battery into the Module.
The lithium battery may erupt if charged.
Note (1) Supply power to the BAT Module and absolute encoders for approx. 10 min before re-
placing the battery so that the SUPER-CAPACITOR of the absolute encoder can be
charged.
(2) Do not touch the board circuits with your fingers or screwdriver.
(3) Be sure that the battery connector is properly lined up with the connector at the board
side. If the pins are not lined up properly, problems can occur with the battery.
(4) If problems occur with the absolute encoders, refer to the methods for setting up the ab-
solute encoders described in the SERVOPACK technical sheet. Set up the absolute en-
coders in accordance with the absolute encoder setup instructions.
