CITECT USER MANUAL

Introduction

This document specifies the operation of an Operator Interface System (OIS) for the monitoring and

storing of coal quality information provided by the COALSCAN 9500 analyser. The COALSCAN 9500

provides a combined ash, moisture and energy result and these are available on the system overview

page of the OIS. The OIS is configured to allow operators to monitor, trend and store in real time, the

coal quality process within the wash plant.

Users are be able to navigate through the COALSCAN CITECT display system with the keyboard and

mouse functions. The analyser trend, mimic and operational displays will be viewable and optionally

selected through the aforementioned methods. The COALSCAN CITECT program runs in a Windows

2000 or Windows NT environment, and uses the features of the Windows Graphical User Interface –

graphics screens (pages), buttons and the arrow shaped cursor that is moved by the mouse

3 DESCRIPTION OF PAGE DETAILS

Below is a detailed description of the individual COALSCAN CITECT pages.

3.1 SYSTEM OVERVIEW

The System Overview window displays the relevant COALSCAN measurement data: % Ash in coal, % Total Moisture in coal, Energy measured in the coal, % Sulphur in coal, % Iron Oxide in the ash, Total Tonnes of coal measured for the relevant period (Figure 3.1). The abovementioned parameters are provided on an Instantaneous, a Tonnes Weighted result, a Shift Average, a Daily Average and two predefined Rolling Average periods. These measurement periods are explained below.

Figure 3.1 – System Overview window

Instantaneous Ash is a predefined measurement period. This timing period can vary between 2 and 10 minutes and can be preset in the Utilities page (see Utilities section).

Tonnes Weighted (T.W.) average is an accumulated result, which can be reset by the user. By clicking on the T.W. Average button, the user can reset all the measurement fields in this accumulator (the display results may take up to 2 minutes to reset). Once reset, the accumulator divides the Tonnes Weighted result for all the relevant measurement data. (This can be used for a total sample collection or stockpile building).

Shift Average provides measurement information for each shift. (The default Shift period begins at 07h00 and is reset again at 19h00 each day. This start and stop time and period are configurable within the COALSCAN 9500.)

Daily Average provides measurement information for each day. (The default Daily period begins at 07h00 and is reset again each day at 07h00. This time is configurable within the COALSCAN unit.)

CITECT USER MANUAL

Clicking on either the Rolling Average 1 or Rolling Average 2 buttons can set up rolling Averages. A choice of time periods between 10 minutes and 24 hours can be selected. The same rolling average can be accessed from the Utilities screen.

A trend graph is displayed below the current results. The trend graph will display the coal quality parameters as a function of time. All the information for the trends will be logged continuously so that the operators will be able to view past trends as well as current trends. Immediately above the trend graph are a series of buttons, which enable the user to navigate the cursor along the current trend page. Navigation buttons include: Move cursor left quickly, Move cursor left slowly, Remove cursor, Move cursor right slowly and Move cursor right quickly. There are seven buttons immediately to the right of the navigation buttons. They represent ash, moisture, energy, sulphur, iron oxide in ash, calcium in ash and tons respectively. Each of these buttons is identifiable by a trend colour.

Immediately right of the trend graph, there are two ´current pen selected’ scale buttons. Using these buttons, the lower and higher limits can be set for the current trend.

Below the trend graph on the left hand side there is a current trend span selection button. This allows the current display trend span to be adjusted from a short period (e.g. 10 minutes) to a very long period (e.g. 12 hours). Immediately below this button is a resolution button, which is interdependent with the current trend span button. This variable should not be adjusted manually. The navigation buttons at the base of the graph enable the user to scroll the length of the current trend span with the following options: Scroll trend left one span, Scroll trend left half a span, Scroll trend right half a span, Scroll trend right one span and Scroll trend to real time. The next group of buttons enable the user to zoom in on the trend, zoom out of the trend, copy the graph to clipboard, copy to file and print the trend. The final set of buttons to the right enable the user to specify an end time and end date for the current trend span.

Various parameters relating to the current COALSCAN status are displayed below the trend graph details. The first parameter provides the operator with information on the current COALSCAN operating mode (either IDLE, STANDARDISE or ANALYSE). The following field indicates whether all detectors are analysing (DETECTORS ALIGNING or DETECTORS ALIGNED). The next field provides information on the coal flow through the analyser (COAL FLOW OK or COAL FLOW FAULT). The last field indicates whether the source is on or off (SOURCE ON or SOURCE OFF).

3.2 TREND PAGE

A trend page will display the coal quality parameters as a function of time. This trend page is similar to the trend graph described in the System Overview Section (Figure 3.2). The trend graph buttons provide the same functionality as described in the system overview page. However, for completeness they are described again below:

Immediately above the trend graph are a series of buttons, which enable the user to navigate the cursor along the current trend page. Navigation buttons include: Move cursor left quickly, Move cursor left slowly, Remove cursor, Move cursor right slowly and Move cursor right quickly. There are seven buttons immediately to the right of the navigation buttons. They represent ash, moisture, energy, sulphur, iron oxide in ash, calcium in ash and tons respectively. Each of these buttons is identifiable by a trend colour.

Immediately right of the trend graph, there are two ´current pen selected’ scale buttons. Using these buttons, the lower and higher limits can be set for the current trend.

Below the trend graph on the left hand side there is a current trend span selection button. This allows the current display trend span to be adjusted from a short period (e.g. 10 minutes) to a very long period (e.g. 12 hours). Immediately below this button is a resolution button, which is interdependent with the current trend span button. This variable should not be adjusted manually. The navigation buttons at the base of the graph enable the user to scroll the length of the current trend span with the following options: Scroll trend left one span, Scroll trend left half a span, Scroll trend right half a span, Scroll trend right one span and Scroll trend to real time. The next group of buttons enable the user to zoom in on the trend, zoom out of the trend, copy the graph to clipboard, copy to file and print the trend. The final set of buttons to the right enable the user to specify an end time and end date for the current trend span.

Figure 3.2 – Trend Page

The trends will be displayed in real time on the trends page or on the overall system view page. All the information for the trends will be logged continuously so that the operators will be able to view past trends as well as current trends.
