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.
