Introduction
Designed for municipal wastewater lift stations and similar
applications, the LEP-Link™ is a simple and effective RTU (Remote
Telemetry Unit) for management of a wastewater collection system
via a cellular network. Alarms are monitored and service personnel
notified in the event of a failure.
Data logging and trending of critical information enables the User
to visually track system performance and recognize impending
problems. The station data can be visualized in a simple and
intuitive way from a web browser on a PC, tablet, or smartphone.
The LEP-Link remote pump monitoring system is designed to be
connected to most simplex or duplex lift station type control
panels. The LEP-Link RTU monitors various pump data and relays
this data to the cloud, via a cellular network, then to a secure
website where it can be accessed and monitored from virtually
anywhere in the world.
Product Information
Two LEP-Link versions are available:
•RTU-100 (Digital I/O only)
•RTU-200 (Analog & Digital I/O)
The RTU module can be ordered for direct panel mounting, or
pre-assembled in a NEMA 4X enclosure for outdoor mounting near
an existing panel, suitable for installation in a fiberglass or
thermoplastic enclosure. An antenna is included with each RTU
unit.
Note: RTU-100 includes one year of cellular service, antenna, and
User Manual; the RTU-200 includes one year of cellular
service, antenna, current transducer, and User Manual.
RTU
RTU-100 and 200 are available for installation inside a control panel.

RTU Features
The LEP-Link RTU monitors pump run, run time, cycles, amps1, and
flow. It can also monitor system in-flow1, power failure, level, and
level alarms1. This data is then accessible via a secure website
where it can be accessed and monitored from virtually anywhere in
the world.
•Li-ion backup battery for power loss detection and
notification
•SMS, email, and web portal alarm notifications
•Graphical HMI with simple and clear station status
display
•View all pumping stations on an interactive map
•Data logging and historical trending
•First year of service included

Sensor Wiring
Connect the RTU-200 current transducer as per the schematics on
page 8. Open the core of the current transducer by pressing on the
lever. Ensure that one incoming power conductor passes through
the center of the current transducer.
Figure 12. Current Transducer Wiring
Wire the pump run inputs to a non-powered auxiliary contact in
the control panel, which closes when the pump is called to run.
These must be wired for each pump.
Motor contactor auxiliary contacts for reference only. Actual
contactor configuration may differ.
Figure 13. Aux Contact Example
Mounting the LLINK Panel
Mount the LLINK panel using a solid base such as treated posts
with a treated plywood overlay. Mounting on Unistrut® or other
metal structure is also common. Use the appropriate hardware for
securely anchoring the LLINK panel to the metal structure.
Figure 14. LLINK Mounting Example
LLINK Panel Wiring
When wiring the LLINK panel, be sure to use liquid-tight conduit or
strain relief fittings. Refer to Figure 10 / Figure 11 (as applicable)
for wiring schematic.

Conduit Options
Use liquid-tight conduit or strain relief fittings to run cables
between the LLINK and the lift station control panel. Do not run
conduit from the LLINK to the wet well.

Activating the Battery
Battery Connection
The RTU units are equipped with an internal Li-ion battery. This
battery will enable operation during power loss (24 Vdc) and send
out alert notifications for power loss and any digital input alerts.
Note: The battery is not able to power the current transducer. The
battery is shipped disconnected and must be switched on before
startup.
