Press STEP. If more than one module is installed, the system automatically advances to the SENSOR CONFIG
message for the next module. Up to 8 modules may be installed. Repeat the steps described above for each
module until you have entered the configuration information (sensor positions) for all modules and the system
displays the ENTER SENSOR LOCATION message.
Vapor Sensor Location
If necessary, press STEP until you see the message:
To enter the sensor location, press TANK/SENSOR repeatedly until the sensor you want appears on the second
line of the message (V1, V2, etc.). Press CHANGE and enter the location (up to 20 alphanumeric characters) of
the selected sensor. Typical entries would be: WELL #1, NEW CORNER, etc. (This information appears on
sensor status and sensor alarm reports to make it easier to identify the location of the alarm.) Press ENTER to
confirm your entry:
Press STEP to continue.
Vapor Threshold
If necessary, press STEP until you see the message:
The SENSOR THRESHOLD message lets you enter vapor levels to identify a leak or serious spillover and to
trigger the vapor alarm. Thresholds are in ohms (
) and must be calculated for each vapor sensor according to the
formula described below. Thresholds may be set to account for existing vapor levels as long as these vapors do
not exceed the limits explained below.
BEFORE YOU BEGIN
IMPORTANT! A vapor sensor must be operated only in wells where preliminary testing has determined that the soil
is not already contaminated beyond acceptable limits (as defined by applicable regulations) or that contaminated
soil has been remediated and is now clean. A vapor sensor should not be operated in wells where preliminary
testing indicates that the initial vapor sensor resistance exceeds 25k ohms. Vapor sensors must have been
installed in their wells at least 24 hours prior to calculating and entering vapor alarm thresholds.
