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 tempera­ture.

• Our sensors have been designed to resist shock and vibration. However, shock and vibration should be mini­mized.

• Electrical entries and mounting points in an enclosed tank may require liquid/vapor sealing.

• Our sensors must not be fi eld-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 offi cer
of Gems, Inc.

UCL-510

Part Number 225100

Manual

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.

Confi guration

UCL-510 is confi gured through Confi guration, a PC software program. Con­fi guration is a free download from Gems website. You must download and
install Confi guration prior to plugging in the USB® Fob. Please go to http://
www.Gemssensors.com/software.

Safety

1. Installation should be done by properly trained staff

2. Supply voltage should never exceed a maximum of 24 VDC

3. Always use stepper relays between the sensor and external loads

4. Make sure the sensor is chemically compatible with your application

5. Design a fail-safe system that accommodates the possibility of sensor and/or power failure.

6. This sensor should not be used in classifi ed hazardous environments

Wiring UCL-510

USB® Fob Interface

After you have fi nished positioning and mounting the UCL-510, use the wir­ing diagram created in the confi guration 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.

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 fi tting

7. Always use a tank adapter with the minimal height possible

Tank Adapter: Select a tank adapter with

minimum height to ensure that UCL-510’s
transducer will not be substantially elevated
inside the fi tting

2” x 1”, thread by thread, reducer bushing.

. Gems recommends using a

Riser: Use the riser specifi cations guide and

match your riser’s inner diameter with the
height.

Flange: Select a fl ange with a thread that is

above the plane of the fl ange. If your instal­lation requires the use of a blind fl ange, tap
a 2” thread and use a thread by thread re­ducer 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.

UCL-510 communicates with the confi guration software through a USB® in­terface called a Fob. Before plugging your Fob into your computer’s USB®

2.0 port, be sure that you have installed the confi guration 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.

* Once the unit has been confi gured, the
White and Green wires must be isolated
from the active power to prevent a shorting
of the confi guration circuit.

Confi guration

With UCL-510 connected to your computer, open the Confi guration soft­ware. Follow steps 1-3 (pg. 4-5) to confi gure the UCL-510. Click “Help” in the
lower right hand corner and follow the help menu for further assistance.

Confi guration Step 1: Confi guration

Confi guration Step 3: Write to Unit

This section of Confi guration is where you select
the application’s confi guration settings. Start
from the top and work to the bottom, choosing
the selections that are applicable to your con­fi guration. “Not Applicable” will automatically
show when a selection doesn’t apply to your
confi guration settings, and you may move on. All
confi guration settings must be selected or have
“Not Applicable” before you can continue to
step 2.

Right click on any menu that you may have ques­tions on to open the help menu.

Confi guration Step 2: Tank Levels

This section of Confi guration is where you enter application measurement
values. All values must be fi lled in before moving to step 3.

Sensor Height: Distance from the bot­tom of the tank to the bottom of the
transducer.

After you have entered confi gurations and tank values, click “Write to Unit”
and send the confi guration to UCL-510. Now use the confi guration soft­ware’s fi le management features to save your confi guration by clicking “Save
Confi g File” and print your wiring diagram by clicking “Wiring Diagram.”

Position and Mount

Positioning and mounting UCL-510 is critical to the sensor performing cor­rectly. 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.

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.

Always use cor­rect tank adapter
(refer to Mounting
Guide on pg. 6)

questions on to open the help menu.
