Repeat .) Choose the actions you want to occur (e-mails, SNMP traps, relays, etc.) from
the checkbox list on the right, then click Save Changes .
Then, click Add New Alarm again, choose “ Leak Detection ” from the list of
measurements, set trips if and threshold to Above and 50 , choose the actions you want, and
Save Changes . In the example shown here, “[email protected]” will be notified if a
cable fault occurs, while both “zed” and “baz” will be notified if a leak detection occurs.
When conditions are normal, both sets of the control box’s relay contacts will be closed,
and the Cable Fault and Leak Detection inputs will read
0 , as shown here.
If water is detected by the sensing
cable, the “leak” relay on the control
box will de-energize, opening the
contacts, and the Leak Detection
input will read
99 , as shown here.
If a fault is detected in the sensing
cable, the “fault” relay on the control box
will de-energize, opening the contacts, and
the Cable Fault input will read
99 , as shown
here. Examples of a cable fault would
include an accidental disconnection of the
leader cable fro m the control box,
disconnection of one of the sensing-cable
segments, a break or cut in either the leader
or sensing cables, or failing to install the
terminator plug or pre-terminated sensing
cable at the end ofthe chain.
If the LD300 control box loses power, both
relays will de-energize, causing the Cable Fault and Leak Detection alarms to occur
simultaneously. Since these events can’t occur at the same time under normal
circumstances (obviously, a faulty cable can’t detect water!), receiving both of these alerts
at the same time would indicate that the Leak Detection Kit itself is no longer functioning.
