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

RTU Troubleshooting
Troubleshooting LEDs
Each input has a corresponding LED indicator above the input
terminal. The relay output also has an LED indication.
RTU Communication
The RTU signal strength can be checked on the web portal. Go to
Setup/Ver & Comm to see the RSSI value.
RSSI Thresholds
RSSI is a measurement of the power present in a
received radio signal (Received Signal Strength
Indicator). The larger the number, the better the
reception.
Below is a guideline to appropriate strength
thresholds:
1-5 = very poor (no communication)
6-8 = poor (inconsistent communication)
9-11 = good (little to no communication issues)
>12 = best

RTU Visualization
Several templates are available to visualize your remote controller. There is a unique template for the RTU-100 and RTU-200. The template
shown below is for the RTU-200.
Figure 32. RTU Visualization
Alarms
RTU-100 and RTU-200:
Alarm 1-4: These alarms become active upon a contact closure (see
Wiring on page 7). The label “Alarm 1” can be changed to describe
the actual alarm condition. Example: “P1 Fail”. See Main Screen
Configuration on page 16 for instructions on how to edit text on
the Main Screen.
LED Indication: The LED indication on the screen will turn red when
the alarm is active. Configure the alert notification by clicking on
the indicator.
Power: If 24 Vdc power is lost for more than the set time (see
Configuration screen). The 3.7 Vdc battery must be connected.
P1-2 Runtime Alarm: The pump ran continuously for longer than
the set time (see Configuration screen). This condition may indicate
a pump clog, a high in-flow event, or sensor fault.
RTU-200 Additional Alarms:
Xdcr High: Level transducer High Level alarm. This alarm set point
and timer value are set in the configuration screen. The tank level
value will change to zero if 24 Vdc power is lost and the RTU is
running on the 3.7 V Li-ion battery. The High Level alarm will no
longer be active during this condition.
It is recommended to have a 24 Vdc battery backup system to
ensure alarm notification during power loss. Alternately, a high
level float switch may be connected to any of the four digital
alarms and activate during power loss.
Xdcr Low: Level transducer Low Level alarm. This alarm set point
and timer value are set in the configuration screen. This alarm will
not be active on power loss (24 Vdc), and running on the 3.7 V
Li-ion battery.
P1-2 High Amps: The pump running amps are higher than set
point for longer than the set timer (see Configuration screen).
P1-2 Dry Run Alarm: The pump running amps are lower than set
point for longer than the set timer (see Configuration screen).
Relay Button
Machine may start unexpectedly and cause serious injury or
death. User must have confirmation that all personnel are free
and clear from moving parts and the electrical panel before
activating the relay remotely.
Only allow qualified operators to remotely activate the relay.
The relay remote operation must be part of a fail safe
electrical circuit that would shutdown the equipment before
failing or cause damage/injury.
Local and National safety codes must be followed.
Pressing the RELAY icon on the screen will remotely energize the
relay in the RTU. The relay will only stay ON for two seconds, then
it will turn OFF automatically.
The label text below the relay button can be edited to describe the
function of the relay. Example: “Silence Horn”.

Ack Fault Button and Indication
The ACK FAULT button must be pressed after an alarm within the set
time (See Setup screen). If an alarm becomes active, the timer starts
and the operator must acknowledge the alarm on the screen
before the timer times out (default value is 20 min). If not
acknowledged, the OK indicator turns red and can be used to
notify other Users of the failure to acknowledge. This function is
useful if only one User is on standby, and may not be able to
respond in a timely manner.
Click on OK to set the Alert notification. Leave it blank if not using
this function.
Station Data (trending available - see Reports
and Trending section)
Wet Well Level: Level of the wet well as measured by the
transducer.
P1-2 Amps: Pump Current snapshot captured 30 sec after motor
start by the current transducer.
P1-2 Cycles: The number of start cycles occurred since midnight.
P1-2 Runtime Minutes: Accumulated motor run since midnight.
View reports (accumulation for full run analysis day/week/month).
Station In-Flow (GPM): The measurements are calculated using
the wet well level, the tank diameter, and the fill time. It is a very
useful data point to track peak flow hours and to detect storm
water infiltration issues.
P1-2 GPM: The measurements are calculated using the wet well
level, the tank diameter, the fill time, and discharge time. It is a very
useful data point in tracing the performance on each pump, and to
understand the effect of changing head conditions.
Pump Data: These values are not measured. They are used as
reference and for recordkeeping. It is valuable to compare the
pump FLA to the actual Amps on the screen for setting High Amp
and Dry Run Alarms. It is also a quick way to check the pump data
before making a service call to the station.

current draw will typically drop 30%
from normal when running dry.
Consult the Liberty Pumps for this
value and test this fault, if possible.
The amp set value corresponds to the
minimum amp value that the pump
should draw during normal operation.
If the current drops below this value
for longer than the Dry Run Delay, the
RTU will display a “Dry Run” fault. The
“Trip Delay” time is used to avoid
nuisance tripping. This alarm requires
the User to click on ACK FAULT to clear.

Flow Monitoring Setup (RTU-200)
Volumetric flow measurement is available when a level transducer
is used in a cylindrical tank. The RTU-200 unit calculates the volume
of liquid based on the level. The flow is calculated by using the
volume and the fill/discharge times. The in-flow and the discharge
flow is measured. The Flow Calc. Level set points are not used for
controlling the pump. They are used for volumetric flow
calculation. The flow calculation is based on the diameter of the
tank, the Start Flow Calc. and Stop Flow Calc. level set points, and
the fill and discharge times. Both In-Flow and Discharge flow are
calculated during every cycle.
Tank Diameter: Enter the tank diameter in ft
Flow Calc. Start Level: See below (in ft)
Flow Calc. Stop Level: See below (in ft)
Important notes on flow setup:
Set Flow Calc. Start Level at least 4” below the pump start level. Set
Flow Calc. Stop Level at least 4” above the pump stop level.
The flow accuracy is better with longer cycle times (2 min or more).
Note: When using a rectangular tank, the equivalent diameter
would be: d .
Example: A 10 x 10 tank would equate to a diameter of 11.28.
Enter this value and get the flow calculations as if it was a
cylindrical tank.

Pump Data
The Pump Data screen is for information only. It is a record of the
pump HP, Volts, and FLA.
Pump HP: Enter pump horsepower.
Pump Voltage: Enter pump rated voltage.
Pump FLA: Enter pump FLA as shown on the nameplate.
