•
Unidepth Averaging
– Select the number of consecutive
UNIDEPTH readings for the monitor to
average to minimize the potential for false alarms due to erroneous depth readings. ECHO alarms are
generated from UNIDEPTH rather than raw LRDEPTH readings.
•
Low Level
– Define the depth at which the monitor will trigger a
Low Level alarm. This event
indicates that the flow depth measured at a location has fallen below a predefined threshold. This
depth should be lower than the lowest depth that typically occurs at the location.
•
Full Pipe
– The depth, taken from the defined pipe height, will trigger a full pipe alarm. This monitor
event indicates that the flow depth in the manhole is greater than or equal to the pipe height as
measured by the
ECHO monitor.
•
High Level
– Define the depth at which the monitor will trigger a
High Level alarm.
•
High High
– Define the depth at which the monitor will trigger a
High High alarm. This value must
be zero when this feature is not in use, or greater than the value entered for the High Level alarm when
it is in use. ADS recommends setting this value at least 2 inches higher than the value designated for
High Level .
•
Overflow
– This event indicates that the
ECHO monitor’s internal pressure sensor has detected the
site is experiencing overflow conditions, where the flow is above the manhole rim.
•
Tilt
– Define the change in angle or orientation, in degrees, that will trigger a
Tilt alarm. This event
indicates that the accelerometer (level) sensor for the monitor is out of level. Until a Tilt return-to-
normal event for the ECHO monitor has been recorded, the only alarms that will be initiated are Low
Battery, Overflow, or Tilt return-to-normal. UNIDEPTH holds the last reading value until the Tilt
return-to-normal event occurs. ADS recommends leaving the Threshold at the default value.
•
Battery Low
– Define the voltage at which the monitor will trigger a battery low alarm. ADS
recommends leaving the Threshold at the default value.
Editing the Data Delivery Device
By default, the ECHO
’s modem is in the
Always Off mode to conserve battery power. Therefore, it is
recommended that the Data Delivery device be configured to upload data stored in the monitor memory to
ADS PRISM and/or an FTP server at an interval designated by the user. To upload data to PRISM and/or
an FTP server, you must know the IP address or DNS of the server. FTP servers also require the username
and password the monitor must use to access the server, and when applicable, the name of the folder on the
server in which the monitor is to place the data.
