1.5 Planning

1.5.1 Overview

Configuration system minimizes decisions

The 9782C Analyzer/Controller was designed for easy configuration using menu displays and the
keys on the front panel. Numeric values such as setpoints and range limits are easy to enter using
the UP and DOWN keys and function keys (see 1.3). Other configuration parameter
assignments are selected by scrolling through a list of available choices using the UP and
DOWN keys.
During configuration only those parameters and choices relevant to features supported by your
Analyzer/Controller's hardware will be available for configuration. For example, if the model
purchased does not contain hardware for the optional analog outputs, then none of the screens
relating to output configuration will be applicable.
Although configuration is a simple process, to make best use of the 9782C Analyzer/Controller
and its features, a little advance planning is recommended.

1.5.2 Using Relays

Relays assigned during I/O setup

Every 9782 model includes two internal relays. Two more relays are available as an option.
During I/O setup (see 5.3) the 9782's software will assign relays to the features you select. The
design of the Analyzer/Controller allows multiple alarms to be assigned to one relay, allowing
greater flexibility with fewer relays. All other 9782 features using relays (AutoClean, range
status indication, and discrete control) require one relay per instance of the feature. You will not
be permitted to select features requiring more that the available number of relays.
Once a relay has been dedicated to a function, the relay will not be available for assignment to
another function. In order to get the most functionality from the available relays, plan your
strategy before implementation. The order in which features are presented (during I/O setup) for
relay assignment is:
1. Cell 1 "Advanced Features" AutoClean and range status indication
2. discrete control (both cells)
3. alarm annunciation (both cells), and Cell 2 AutoClean and range status
