Alarms and Warnings
On the 834 Console there are three LED's for indication of alarms or warnings.
• The Speed alarm LED flashes when no speed pulses are
received during spraying (Master in the ON position). This
indicates that there is something wrong with the speed sensor
or that you are standing still while spraying.
Note: When this alarm is triggered, the display will
automatically switch the application display to view
speed (if not currently viewing speed) and the speed
display will flash off and on as well. This allows the
operator to immediately determine the location of the
problem.
• The Press alarm LED flashes when the signal from the
pressure sensor drops below 4mA while spraying (Master in
the ON position). This indicates that the pressure sensor is
not working properly.
Note: When this alarm is triggered, the display will
automatically switch the application display to view
pressure (if not currently viewing pressure) and
the pressure display will flash off and on as well.
This allows the operator to immediately determine
the location of the problem.
• The Density LED is a warning LED and it will be lit when the
density selected in the programming mode is different from 1.00
(e.g. the density of water). This LED warns the user that
the console is working with a density factor different from 1.00.
