Cameron Scanner 3100 EFM - Section 6-Scanner 3100 EFM Maintenance; Lithium Battery Pack Replacement

Section 6—Scanner 3100 EFM Maintenance
The Scanner 3100 is engineered to provide years of dependable service with minimal maintenance. Batteries require pe-
riodic replacement, and battery life depends on (1) whether battery power is the primary or secondary power source, (2)
the conguration settings of the Scanner 3100, and (3) ambient temperature conditions.
All conguration settings are stored in nonvolatile memory; therefore, conguration settings will not be lost in the event
of power failure.
!
WARNING: Before servicing the Scanner 3100, disconnect all power sources/signal sources or verify that
the atmosphere is free of hazardous gases. Do not remove the cover while circuits are alive. The Scanner
3100 poses no hazard when opened in a safe area.
Lithium Battery Pack Replacement
Two integral battery packs provide backup power for the Scanner 3100 when external power is present, and can sustain
the device for short periods as an autonomous power supply. Battery life can vary, depending on the power demands of
the conguration. As an autonomous supply, the dual battery packs have an estimated life of 2 to 3 weeks, assuming the
device is congured with a base load.
A battery capacity indicator in the Scanner 3100 display helps users predict the need for battery replacement. See Table
5.1—Device Status Glyph Denitions, page 80, for details. Battery replacement is recommended when the indicator
shows capacity to be 50% or less. Battery levels typically remain high (full) for the majority of a battery’s life and then
deplete quickly near the end of the battery’s life.
When two packs are installed, a user can replace a spent battery pack without interrupting operations.
!
WARNING: The lithium battery pack that powers the Scanner 3100 is a sealed unit; however, should a lithi-
um battery develop a leak, toxic fumes could escape upon opening the enclosure. Ensure that the instru-
ment is in a well-ventilated area before opening the enclosure to avoid breathing fumes trapped inside the
enclosure. Exercise caution in handling and disposing of spent or damaged battery packs. See additional
information in Lithium Battery Disposal, page A-1.
Replacement Procedure
The stick-style battery packs are installed in a compartment just below the display (Figure 6.1). Battery leads are con-
nected to the Scanner 3100 via two connectors extending from the back side of the display assembly on either side of the
rounded cutout.
