Figure 25 Set-up 4-20mA Outputs
For example, assume setting up two AO-4 modules. Make sure to set each AO-4 module to a unique module
address using the front panel switches. The values should then look like this:
CH#
AO4 Address
01 thru 04 81
05 thru 08 85
09 thru 12 89
13 thru 16 8D
5.0 System Operation
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. The outline of the key will change momentarily when
activated properly.
The graphic display is back lit. The contrast can be adjusted using the ‘Screen Utilities’ function described in
section 5.3.
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 – User Tag – (F, NC, C). When there is an active alarm or
fault condition, the problem channel # will be shown in reverse video. A channel number in flashing reverse
video represents a channel that is actively in alarm/fault/No Comm or has cleared alarm but was set to latching
mode in the relay output. A Fault will also be represented by the letter “F” flashing after the user tag. A No
Comm condition will also be represented by the letters “NC” flashing after the user tag. An in-cal condition
will be represented by the letter “C” flashing after the user tag.
