circuit mode. To utilize this function effectively, you will need to connect a
device to the appropriate output so that you can tell when it is turning on or
off.
You can connect an ohmmeter to the outputs and see if the output changes
state (low for closed or high for open). You may also connect your electri-
cal device to one or more of the outputs. You can check to see if the unit
runs with the Output circuit closed or fails to run with the Output circuit
open.
To leave this mode, simply exit the dialog box by pressing the OK button.
Alarm Logging
Select the check box “Enable Alarm Logging” to enable logging of alarm
events.
Press Download Logs to retrieve a log of alarm events. The program will
write to a file named Alarm Download XX-XX-XX.txt where XX indi-
cates the month, day and year, respectively. This file will be located in the
Streaming Data Utility directory under your WeatherLink directory. When
download is complete, the text file will automatically open.
The log will consist of which output became active, which parameters
caused the alarm to become active (useful for the OR type alarm) along
with the date and time that the alarm became active. This log is cleared
whenever any of the output alarms are cleared.
Press Clear Logs to erase any logged alarm events.
