5.0 Operator Interface
5.1 Using the Touch-screen Display
The Operator Interface is conducted through a graphic touch-screen backlit display. A suitable small blunt
device such as the Detcon stylus wand should be used to conduct touch-screen interaction.
NOTE: Sharp objects such as pens, pencils, screwdrivers…. etc. will permanently damage the display
and void the warranty. The use of fingertips to activate keys is permissible, but is difficult due to the
small press key areas in some cases. A pencil’s eraser tip is a suitable alternative.
In general, displayed items that are outlined with a box represent Press Keys. Press Keys should be firmly
pressed down for about 0.5 seconds to engage properly. They will illuminate momentarily when activated
properly.
The graphic display has backlighting that turns on after any touch-screen activity. It turns off automatically
after 1 minute of touch-screen inactivity. Backlighting will automatically be maintained during any abnormal
condition. The contrast and backlighting can be adjusted using the ‘Screen Utilities’ function described in
section 5.4.
5.2 Main Display
The main display shows the status of the active gas channels. They are labeled by channel number, reading,
units and gas type. Example: CH1 - 0ppm - H2S. Under non-alarm condition, if the line entry is pressed it
will momentarily display the tag name for that channel. Example: CH1 Well Head #7.
When there is an active alarm or fault condition, the CH1 will be shown in reverse video. If this line entry is
then pressed, the current alarm/fault status will alternately be displayed. A channel number in reverse video
represents a channel that is actively in alarm/fault or has cleared alarm/fault but was set to latching mode for
the relay output.
Figure 3 Main Display
Channels are displayed in user selectable groups of up to eight per screen, called ‘Zones’. The ‘Zones’ are
represented by keys labeled across the bottom of the main display as Z1 and Z2 for the 1600 and Z1 through
Z8 for the 6400. To view a particular ‘Zone’ press the appropriate key on the screen. During normal
operation, the display will rotate between zones at 10-second intervals, displaying each zone for 10 seconds
and moving on to the next zone.
