Contamination
Alarm Delay
The amount of time that passes between the time a
contamination is detected and the annunciation of the
contamination alarm. The contamination trip point must be
exceeded for the duration of this delay.
Enter a value between 5 and 990 seconds.
Default setting: 40 seconds
Resistance Per
Foot
The resistance per foot 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 Delay 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.
The interval is adjustable in whole hour increments. Decimal
values are not allowed. 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
