4Installing the Cable
The LD1000 includes a 15-foot (4.57m) leader cable and an end-of-line (EOL)
terminator.
1
Connect the stripped end of the leader cable to the terminal block
labeled “Cable” on the LD1000.
2
With the screws of the terminal block connector facing up, connect the
leader cable wires in this order from left to right: white, black, green, and
red.
Once the leader cable is plugged into the terminal blocks, it is ready to
be connected to the sensing cable. Perform these steps:
3
To do this, unscrew the EOL terminator from the end of the leader cable.
4
Attach the first length of sensing cable to the leader cable.
5
Route the sensing cable according to a cable layout diagram. For
assistance, contact RLE Technical Support.
6
Secure the EOL terminator on the unoccupied end of the sensing cable.
5Setting the Leak Sensitivity
Adjust R25 to set the desired leak sensitivity. By default, it is set to the mid-
sensitivity setting (150mA) and may be adjusted to the low (300mA) or high
(25mA) sensitivity setting by turning the dial.
6DIP Switch Settings
SW1-1: Configures the output relays as supervised or non-supervised. If the
relays are supervised, the relays remain on until either power is disabled or an
alarm is detected (relay turns off). If the relays are non-supervised, the relays
will turn on when an alarm is detected.
Off – Non-supervised (factory default)
On – Supervised
SW1-2: Configures the relays as latching or non-latching. If the relays are
latching, then the relay will remain in alarm state (depending on SW1-1,
supervisory setting) upon alarm until the Quiet/Reset/Test switch is pressed.
If the relays are non-latching, then the relay will remain in an alarm state upon
alarm until the Quiet/Reset/Test switch is pressed or the condition that caused
the alarm returns to normal.
Off – Non-latching (Factory Default)
On – Latching
SW1-3: Configures the two output relays as a summary alarm or as two
separate leak and fault alarms.
Off – Relay one is a leak alarm, and relay two is a fault alarm (factory
default).
On – Relay one is a summary alarm, and relay two is a summary alarm.
SW1-4: Configures the Alarm Delay setting. This is the response time it takes
for the unit to report an alarm condition (Leak or Fault) once detected. The
alarm must be present during this entire period.
Off – 10 seconds (factory default)
On – 2 minutes
7Setting the Audible Alarm
The audible alarm can be disabled for the LD1000. Remove the jumper cap
from JMP2 to disable. This jumper cap is required if audible alarms are
desired.
