7B QS841A System Controller
Overview
The QS841A controller is the integrated network controller option that can be custom
configured for a specific system or customer need. It provides system monitoring and control
features, as well as office alarm outputs from rectifiers, LVD boards, and remote modules.
This section describes the controller features, functions and alarms from perspective of a user
utilizing the front panel display. All these features are available through Web pages accessible
from the Ethernet port. The controller content in the web pages versus the front panel is
arranged differently due to the available large space that comes with using a monitor screen.
However, the majority of the information content, commands, and configurable items remain
the same as those on the front panel. This section focuses on describing the controller from
the front panel perspective which is applicable to respective feature implementation in the
web pages.
