The level value is not
accurate with the actual
level of waste in the
trash bin.
5.1
The transducer is covered by a thin
layer of dust or particles.
Clean the transducer surface with a
soft detergent and clean water.
5.2
The A & B parameters are wrong or
not written to the sensor yet.
Check the calculation of A&B again
and make sure they are written
successfully to the sensor.
6 HW_Error = 1 6.1
The lost connection between the
transducer and the main PCB.
Open the sensor housing and check
the internal wire and connector from
the transducer to the wireless PCB.
6.2 The transducer got a problem.
Please consult the manufacturer for
a warranty or replacement.
There are no moving parts or consumed parts in the ULA ultrasonic level sensor. Therefore there is no need to do
maintenance.
However, depending on the installation environment, the transducer must be checked and cleaned periodically
for accurate measurement.
This ULA Ultrasonic level sensor has the default configuration. The user can change the configuration on the wireless
transmitter so that the complete sensor (tran wireless) delivers the proper output value. Below are some
configuration parameters that store in the flash memory of the wireless transmitter.
