Section 6—Scanner 2000 Maintenance
The ATEX-certied Scanner 2000 for Foundation ™ Fieldbus is fully compliant with European ATEX
Directive 94/9/EC. User repairs are to be limited to the battery and component replacement procedures
described in this manual. All other repairs are to be carried out by the manufacturer, or its approved agents, in
accordance with the applicable code of practice (e.g. IEC 60079-19).
The Scanner 2000 is engineered to provide years of dependable service with minimal maintenance. Batteries
require periodic replacement, and battery life depends on battery power usage, the conguration settings of
the Scanner 2000, and ambient temperature conditions.
All Modbus conguration settings are stored in nonvolatile memory; therefore, conguration settings will not
be lost in the event of battery failure.
The main board, keypad, eldbus interface board, or eldbus module may also require replacement over the
life of the instrument. Replacement procedures are provided in this section.

The lithium battery supplied with the Scanner 2000 has a typical life expectancy of 1 year when used as a
primary power source. Batteries will last considerably longer when used as a backup power source, secondary
to the eldbus-supplied power.
