Display Screen - Honeywell OELD Operating Instructions Manual

6.1.3 Display Screen

The OELD features a backlit liquid crystal display (LCD) with high-intensity multi-color LEDs to show normal, alarm, fault and
communication status.
During normal operation the instrument LCD shows a steady GREEN backlight. In case of a gas alarm or fault the red or yellow
backlight respectively will flash. The screen is visible through the window of the OELD top cover and the display shows the gas
concentration information both graphically and numerically, as well as other information including full scale range, measurement
units, alarm / fault status etc.
Note
At low temperatures, the OELD automatically lowers the refresh rate of the display to maintain optimal readability.
Note
At extreme low temperatures (typically less than -40°C), a reduction in screen clarity may be experienced. The display module
will not be damaged by this condition and will recover once normal operating ambient temperature has returned.
