Important Points:
• Gems products must be maintained and installed in strict accordance with the National Electrical Code and the
applicable Gems product instruction Bulletin that covers installation, operation and proper maintenance. Failure to
observe this information may result in serious injury or damages.
• The supply voltage to the sensor should not exceed 36 VDC, Max.
• Please adhere to the pressure and temperature limitations shown. These limitations must not be exceeded.
These pressures and temperatures take into consideration possible system surge pressures/temperatures and
their frequencies.
• Selection of materials for compatibility with the media is critical to the life and operation of Gems products.Take
care in the proper selection of materials of construction, testing is required.
• Avoid over tightening when mounting.
• Life expectancy of switch contacts varies with application. Contact Gems if life cycle testing is required.
• Ambient temperature changes do affect switch set points, since the gravity of a liquid can vary with tempera-
ture.
• Our sensors have been designed to resist shock and vibration. However, shock and vibration should be mini-
mized.
• Electrical entries and mounting points in an enclosed tank may require liquid/vapor sealing.
• Our sensors must not be field-repaired.
• Physical damage sustained by product may render it unserviceable.
This warranty may not be extended, altered or varied except by a written instrument signed by a duly-authorized officer

UCL-510
Part Number 225100

Level sensing at its best!
Thank you for purchasing Gems new innovative small tank solution.The
UCL-510 is a general purpose sensor that combines switch, controller and
transmitter capabilities for small tanks 49.2” (1.25 m) or less.
Configuration
UCL-510 is configured through Configuration, a PC software program. Con-
figuration is a free download from Gems website. You must download and
install Configuration prior to plugging in the USB® Fob. Please go to http://
www.Gemssensors.com/software.

USB® Fob Interface
UCL-510 communicates with the configuration software through a USB® in-
terface called a Fob. Before plugging your Fob into your computer’s USB®
2.0 port, be sure that you have installed the configuration software on your
computer.
Connect the red, green, white and black wires from UCL-510 into the correct
terminals on the Fob.Tighten the screws on the terminals and plug your Fob
into the USB® 2.0 port of your computer.
Configuration
With UCL-510 connected to your computer, open the Configuration soft-
ware. Follow steps 1-3 (pg. 4-5) to configure the UCL-510. Click “Help” in the
lower right hand corner and follow the help menu for further assistance.
Mounting Guide
1. Do not mount at an angle
2. Liquid should never enter the 2” dead band
3. Mount at least 2” from the side wall
4. Do not mount where obstacles will intrude on 2” beam width
5. Do not mount in a vacuum
6. Never screw directly into tank, always use a non-metallic fitting
7. Always use a tank adapter with the minimal height possible

Wiring UCL-510
After you have finished positioning and mounting the UCL-510, use the wir-
ing diagram created in the configuration software to wire the unit. Always
use an external relay in-between UCL-510 and any components. Gems
Sensors recommends using a licensed electrician to wire UCL-510 and your
application’s components. Once the UCL-510 is mounted and wired, observe
your application and double check your relay set points.
Tank Adapter: Select a tank adapter with
minimum height to ensure that UCL-510’s
transducer will not be substantially elevated
inside the fitting. Gems recommends using a
2” x 1”, thread by thread, reducer bushing.
Riser: Use the riser specifications guide and
match your riser’s inner diameter with the
height.
Flange: Select a flange with a thread that is
above the plane of the flange. If your instal-
lation requires the use of a blind flange, tap
a 2” thread and use a thread by thread re-
ducer bushing (see tank adapter).
Stand Pipe: Use a stand pipe when surface
foam or turbulence are present. Use a 2”
diameter pipe or larger with a length that
runs the distance of the span. Cut a 45º
notch at the bottom and a 1/4” hole within
2” from bottom of the transducer face.

This section of Configuration is where you select
the application’s configuration settings. Start
from the top and work to the bottom, choosing
the selections that are applicable to your con-
figuration. “Not Applicable” will automatically
show when a selection doesn’t apply to your
configuration settings, and you may move on. All
configuration settings must be selected or have
“Not Applicable” before you can continue to
step 2.
Right click on any menu that you may have ques-
tions on to open the help menu.
Configuration Step 3: Write to Unit
After you have entered configurations and tank values, click “Write to Unit”
and send the configuration to UCL-510. Now use the configuration soft-
ware’s file management features to save your configuration by clicking “Save
Config File” and print your wiring diagram by clicking “Wiring Diagram.”
Position and Mount
Positioning and mounting UCL-510 is critical to the sensor performing cor-
rectly. UCL-510 should always be mounted perpendicular to the liquid in
the tank, clear of any obstructions in the beam path. Not doing so will result
in poor performance. Refer to Gems mounting guide on pg. 6 for further
instruction.
Always use
supplied Viton®
Gasket
Always use cor-
rect tank adapter
(refer to Mounting
Guide on pg. 6)
Always mount
perpendicular to
the liquid in the
tank and clear of
any obstructions
in the beam path.
Sensor Height: Distance from the bot-
tom of the tank to the bottom of the
transducer.
Fill Height: Distance from the bottom
of the tank to the maximum liquid
height.
Relay Set Points: Distance from the
bottom of the tank to set-points.
Right click on any value you may have
questions on to open the help menu.
