Battery Replacement Time Periods

If the module is kept in storage, or it is turned off (no 24 VDC supply) most of the time,
then the battery life is shortened, and it must be replaced according to the specifications in
Table 11-3.
If the module is turned on with 24 VDC supplied to its MB-10 amplifier more than half the
time, then the battery life is increased and the replacement period is extended.

half of the time.

Battery Replacement Procedures

The encoder batteries are easily accessible on most modules by removing the motor end
cap. In these situations, the battery replacement can be performed without removing 24
VDC power and without having to recalibrate the system. On some modules it may be
necessary to remove all power from the system, remove the MB-10 amplifier, motor
endcap, and extruded motor cover, in order to gain access to the battery. Please follow the
following procedures for either case.
1. Obtain a replacement encoder battery. Adept p/n 05142-000.
NOTE: The photo in the procedure detailed in the following section shows
an L18 module. The procedures for L12 or L08 modules are very similar;
therefore, you can follow the steps provided here.

Battery Accessible via End Cap Removal

1. Leave power turned on to the PDU3, and push the E-Stop button on the Front
Panel. In this procedure, you want to have the 24 VDC power supplied to the
encoder, so you do not have to recalibrate the axis.
2. Remove the end cap from the module by removing four screws. See
3. Pull the external battery out from inside the module and disconnect it from the
wiring harness.
4. Plug the new external battery into the wiring harness, and secure it inside the
module.
5. Replace the end cap on the module.
The system should be ready to use, with no calibration required.
