LD310-24V

Description

Parameter’s most cost effective controller, the LD310-24V is easy to install and provides reliable leak detection as either a standalone device or integrated into a larger BMS platform. The LD310-24V single zone leak detection controller monitors up to 300 feet (91 meters) of sensing cable. It is compatible with all of RLE Leak Detection sensing cables, as well as SD-Z and SD-Z1 spot detectors.

When your system is in alarm, the LD310-24V will notify you via:

Audible alarm
Visible LED
Leak and fault relay outputs

Where Should You Use The LD310-24V?

Ideal for smaller contained areas like air conditioner condensate pans. The LD310-24V is most commonly installed in facilities with pumps, chillers, boilers, water control valves, and around air conditioner condensation pans.

Make Sure You Have An Isolated Power Supply!

RLE Leak Detection controllers, including the LD310-24V, require an isolated power supply. A power supply is not included with the LD310-24V. Purchase our PSWA-DC-24-ST power supply.

Technical Notes

Use the Right Power Supply
The LD310-24V requires an isolated 24VDC power supply. A power supply is not included with the LD310-24V. Purchase Parameter power supply PSWA-DC-24-ST with the LD310-24V.

Supervised vs. Non-supervised Relays
Wondering about the relay on the LD310-24V? It’s the question we hear most often. Here’s what you’ll need to know:

If the relay is supervised:
The relay remains ON until either power is disabled or an alarm is detected – at which time the relay turns OFF.
If the relay is non-supervised:
The relay remains OFF until an alarm is detected – at which time the relay turns ON.

Adjust DIP switch SW2.1 (or jumper JP2 on some models) to make the relay output supervised or non-supervised. You’ll notice that, by default, the relay is configured as non-supervised.

** If you change the settings, you must cycle power to the unit in order for it to recognize the change. **
