4.2 Normal Operation
The Main Display is a 1¼” x 6” backlit LCD that has 4 lines by 40 characters. In normal operation, the
configured channels are displayed up to 8 channels at a time. The LCD displays will refresh itself about
every 10 seconds and will display the next 8 channel group and so on until the LCD cycles back to the first
8 channel group and repeats the process. When the CXT is in alarm, the display will stay on the channel
group with the channel in alarm. If two or more channels in different groups are in alarm, the display will
cycle through all the groups with alarms. The user can manually advance to the next group using the arrow
switches. Each channel’s information is shown as:
XX> YYY “Device Tag”
Where ‘XX’ is the channel number, ‘YYY’ is the current gas concentration value, and “Device Tag” is the
description of the sensor. If any channel is in an alarm condition, “XX> YYY IN ALARM#” will be
displayed for that channel. If any gas channel is in fault, “XX> YYY IN FAULT” is displayed for that
channel. If any channel is not communicating that channel will display “XX> 0 COMM ERR”.
Four LED indicators on the front panel show alarm and fault alarm status. The LED’s represent ALM 1
(yellow), ALM 2 (yellow), ALM 3 (red) and FAULT (blue) and are labeled respectively.
