The front panel display is comprised of a digital display and a series
of labeled indicating LED’s. The seven-segment, four-digit display
indicates a variety of information, such as ammonia concentration
and external temperature (if an external temperature sensor is in
use), and more, depending on the position of the rotary selector
switch. Ammonia concentration is displayed in parts per million
and temperature is displayed in degrees Fahrenheit (“F”). The
LED’s provide an indication of ammonia concentration and alarm
status at a glance.
For information on how the display indicates ammonia
concentrations, see the sections on ammonia leak indication.
