Timekeeping BE1-11m
Replacement of the backup battery for the real-time clock should be
performed only by qualified personnel.
Do not short-circuit the battery, reverse battery polarity, or attempt to
recharge the battery. Observe polarity markings on the battery socket
when inserting a new battery. The battery polarity must be correct in
order to provide backup for the real-time clock.
Failure to replace the battery with Basler Electric P/N 38526 may void
the warranty.
Battery Replacement Procedure
Battery access is located behind the front cover of the BE1-11m on the front-panel circuit board. See
Figure 51-3.
Step 1: Remove the BE1-11m from service.
Step 2: Use a 7/64” hex tool to remove the front cover screws and remove the cover.
Step 3: Locate the battery holder attached to the rear of the cover. Remove the old battery. Consult
your local ordinance for proper battery disposal.
Step 4: Insert the new battery so that the polarity markings on the battery match the polarity markings
on the battery holder and circuit board.
Step 5: Reattach the front cover by pressing equally and firmly on both sides as shown in Figure 51-4.
Using a 7/64” hex tool, tighten the front cover screws to 10 in-lbs (1.12 N•m).
Step 6: Return the BE1-11m to service.
