1. Safety Tips
It is expressly prohibited to modify or change products for safety reasons，repair or replacement only allows the
use of accessories specified by the manufacturer.
1.1 Explosion May Result In Death or Serious Injury.
When installing equipment in an explosive atmosphere, be sure to follow applicable local, national, international
standards, codes, and procedures. Be sure to install the equipment in Intrinsically safe or non-flammable site
operating procedures.
1.2 Process Leaks Can Cause Serious Injury or Death.
Care should be taken to lift the transmitter. If the process seal is damaged, the medium may leak at the joint.
1.3 Failure to Follow Safe Installation Guidelines May Result In Death or Serious Injury.
The operations described in this manual are performed by professionally trained and qualified professionals or
end-user specialized professionals to complete.

4. Transmitter, signal output section.
5. Self-test components, including handles, forks and dials.
2.2 Operating Principle-Figure 2
The ordinary float level switch, when the level of the measured medium rises or falls, is affected by the buoyancy
force, and the float ball is lifted and lowered, and the connecting rod magnet at the end of the connecting rod is
driven to swing up and down in the opposite direction. Through the magnetic coupling action, the magnetic steel
of the same magnetic pole mounted in the meter head is pushed up and down in the opposite direction to the
magnetic steel, and the movable contact at the end thereof is connected between the static contact 1-1 or 2-2
group or disconnect, so that the external control device is turned on or off, so that the control signal alarm device
alarms or starts and stops the electric pump.
During the lifting and lowering of the float, only when the float is in the upper and lower limit positions, the
movable contact will be turned on or off at the static contact, so that the external control device is turned on or
off. In turn, the signal alarm device is controlled to alarm or start and stop the electric pump. In the process of
raising and lowering the float with the level, there is no continuous signal output, and only the original on or off is
maintained.
The self-checking float level switch adds a self-test part in the measuring part and the output part. When the
self-checking handle is pulled, the shifting fork is pulled to trigger the dial to make the floating ball reach a high
level or a low level. Check if the controller and system are normal.

Figure4 Sample Nameplate
5.1.2 Check the quantity of each part against the packing list and the material is correct.
5.2 Check Content
5.2.1 Check if the probe is bent, and check the probe at the connection with the meter head.
6. Installation
6.1 Installation Tool
6.1.1 Wrenches, flange gaskets and flange bolts for process connections.
6.1.2 Level
6.2 Installation Technical Requirements
6.2.1 Ensure that the lead length L and inner diameter of the equipment are suitable for the selected float level
controller to ensure that the float is in the tank.
6.2.2 Pay attention to the distance between the tank flange and the inner wall of the tank and the diameter of the
tank when installing, to ensure that the limit bracket is flexible in the tank.
6.2.3 Ensure that the horizontal level of the equipment is within 3 °.

WWW.DDTOP.COM
6.2.4 Ensure that no ferromagnetic particles in the medium may be attracted to the controller's magnetic steel rod
to affect the switching performance.
6.2.5 The level surface fluctuation frequency of the measured medium shall not be too large, and the fluctuation
range shall not exceed the allowable action limit.
6.3 Installation Process
6.3.1 Installation (see
Figure5 Istallation
1. Place the gasket on the flange sealing surface of the container.
2. Carefully pick up the controller and load the float into the container.
3. Align the controller flange with the container flange to ensure that the controller wiring is facing downwards
(except for the top mounting method). Rotate the controller flange to align the bolt holes. Make sure the flange
gaskets are installed correctly.
4. Install flange bolts and nuts. Alternately tighten flange bolts.
6.3.2 Step Adjustable.
The action range of the UQK-102 float level switch is a step-by-step adjustment,by adjusting the position of the
positioning pin on the fan-shaped lever, changing the swing angle of the float, the desired action limit can be
obtained, and the maximum action limit is 550mm. If there is no special requirement, the factory setting limit pin
position is shown in Figure 6, the action limit is 45mm.
Figure 6 Step Adjustable

6.3.3 Steplessly Adjustable
The UQK-103 float level switch has a stepless adjustment range, see Figure 7. The movement limit is adjusted by
changing the relative positions of the upper and lower limit screws of the float guide bar, and the adjustment
range is 0 to 1000 mm. There is a slidable counterweight on the balance bar. When the upper limit is used,
moving the counterweight makes the right side slightly lighter than the float side (excluding the float). When the
lower limit is used, the counterweight side should be slightly heavier than the float side (Does not contain floats)
weight. UQK-103 float level switch controller float diameter Ф140, larger than flange nominal diameter DN80, so
its top cover must be removable.
Figure 7 Stepless adjustable
7. Debugging
7.1 Preparation for commissioning
7.1.1 Debugging Tool: Multimeter
7.2 Electrical Wiring
7.2.1 Cable preparation: Wiring should be Ф10mm OD five-core rubber sleeve cord or rubber cable, one core is
the inner grounding wire, and the other four cores are for a pair of normally open and normally closed contact
wires (using two cores),or for two pairs of normally open, normally closed contacts.
7.2.2 Electrical wiring
1. Remove the cover.
2.According to the wiring diagram wiring, please note that the over-reporting and under-reporting switches are
opposite. Be sure to connect to the correct terminal according to the wiring diagram (see Figure 8). For the SPDT

12 / 14

form, the high-level report is normally open, and the low-level report is normally closed. For the DTDP form, the
high-level report is normally open-common-side, low-reported normally-closed-common.
Figure8 Electrical wiring
3. All terminals should be in good contact, the output nut should be properly pressed to prevent the lead from
loosening.
4. Make sure the wiring port is pointing vertically downwards. Make sure that the extra wires do not interfere with
the movement of the switch cover or switch mechanism.
7.3 Debugging Process
7.3.1 Ordinary float level controller, lift or lower the float to simulate level lift before installation, and use a
multimeter to verify whether the output status is correct (Figure 8 output status is empty can state).
7.3.2 Self-checking float level controller, use multimeter to verify whether the output status is correct. Under the
empty tank state, simulate the high level and pull the self-test handle downward. Then use the multimeter to
check whether the signal is switched once, then pull up. Dynamically simulate a low level and use a multimeter to
check if the output is correct. Note that the position of the handle must be placed at the working position after
commissioning (see Figure 9)

8. Precautions
8.1 The density of use should be the same as the design density. If the density changes, please contact the factory
to confirm whether it can continue to be used.
8.2 Make sure the power supply is safe and reliable, and must be powered off before opening the cover.
8.3 When the vibration is large, it is not suitable to use the float level switch.
8.4 Medium with viscosity ≥500mPa/s is not suitable for use with float level switch.
8.5 Medium with ferromagnetic particles is not suitable for use with float level switch.
8.6 After wiring, tighten the power supply cover to prevent the instrument from getting wet.
9. Fault Analysis and Elimination
Fault Phenomenon
Cause of Issue
Troubleshooting Method
The level to the
specified position
switch does not work.
1. The ball is too heavy, not floating.
2. The installation location is wrong.
3. The lead pipe is too long, the float ball is
stuck in the lead pipe and does not
reach into the tank.
4. Ferromagnetic particles or obstacles in
the medium cause the float ball to
block.
5. Transmitter failure.
6. Self-checking level controller handle
position is wrong.
1. Confirm the density or replace the float.
2. Confirm the installation position
according to the instructions, and make
sure the wiring is punched down.
3. Confirm that the order neck is larger than
the length of the guide tube. If the neck
is small, contact the factory to replace
the relevant parts.
4. Remove the instrument to clean the float
and connecting rod.
5. Replace the transmitter.
6. The handle position is moved to the
working position.
