Resistance Per Foot The resistance per foot (or meter) of cable determines the
LD5200’s ability to accurately detect the cable length installed and
calculate distances to leaks. Adjust this value to fine-tune the
accuracy of a distance-read leak detection system.
RLE’s orange water sensing cable has a base resistance of 2.800
ohms per foot. Most other sensing cables, including RLE’s green
chemical-resistant sensing cable, have a base resistance of 4.000
ohms per foot. Consult the sensing cable’s datasheet for further
information.
Refer to “Calibrate Cable Resistance” on page 25 for detailed
resistance calibration.
The resistance value must be entered as a 4-digit number between
2.000 and 4.250, with one number in the tens place and three
numbers past the decimal point (x.xxx).
Default setting: 2.800 ohms per foot.
Re-Alarm Interval The LD5200 can be set to re-alarm - after a leak or contamination
has been detected, the alarm will be re-sent at a defined interval
until the alarm condition has been resolved. The re-alarm triggers
both the audible alarm and the direct notification alarm.
Enter a number from 0 to 24. A 0 in this field turns off the re-alarm
option, so only one alarm notification will be sent for each alarm.
Default setting: 0 (disabled)
Measurement
Display
Select either feet or meters to calibrate the LD5200 to the preferred
unit of measure. All distance calculations will adjust accordingly.
Default setting: Feet
Latching Alarms A non-latching alarm resets itself once a detected leak or
contamination has been resolved.
A latching alarm must be manually acknowledged before its
annunciation clears, even if the detected leak or cable problem is
no longer present.
Select Yes (latching) or No (non-latching).
Default setting: No (non-latching alarms)
Audible Alarm Select Enabled to activate the audible alarm annunciation. Disable
this option to deactivate the audible alarm annunciation.
Default setting: Disabled
