Liquid level sensor

SLS Lab Pro Digital Ultrasonic Baths 6 C6056801
Operator instructions
When the power is turned on and the bath is full of liquid, the following screens will
display alternately.
When the water temperature is at or above the temperature set, the message “Temp
OK” will display.
The actual temperature in the bath will vary and will be different to the value shown in
the screen above.
To immediately start the cycle using the already set cleaning parameters, press the 8
key.
Your SLS Lab Pro ultrasonic bath remembers the set parameters from the previous
cycle. If the operator wants to run the same cleaning cycle, it is therefore not
necessary to run through the menu each time.

SLS Lab Pro Digital Ultrasonic Baths 7 C6056801
When the power is turned on and the liquid level is too low, the following screen will
display.
The level sensor can be disabled for specialist cleaning applications where deionised
(DI) water is used (see page 19).
When the bath is filled with liquid to the correct level, you will be given the option to
degas. (The need for degassing is explained on page 25).
You will need to degas the liquid to ensure good cleaning efficacy.
By choosing YES, your SLS Lab Pro ultrasonic bath will run an automatic de-gas
cycle. The following screen will display.
The degassing process is to remove all bubbles from the water as these impede the
cleaning performance. Once all the bubbles have come to the surface, complete the
degassing cycle by pressing the 8 key.
Note: If the machine detects low liquid level for more than 5 seconds, it is assumed
that the bath has been filled with fresh water, and you will be given the option of
running another degas cycle.

SLS Lab Pro Digital Ultrasonic Baths 12 C6056801
Screen 5: Frequency Leap
Your SLS Lab Pro ultrasonic bath is equipped with Frequency LEAP technology to
provide more homogeneous ultrasonic cleaning activity throughout the whole tank.
Using advanced software and generators, the SLS Lab Pro ultrasonic bath uses
Frequency LEAP to create a pseudo-random leaping action between a wider
frequency range, reducing standing waves and improving the cleaning action.
For different cleaning applications the operator can choose between Frequency LEAP
and traditional ultrasonic activity.
Use the ON and OFF keys to select the required option.
Once the correct option is selected, press the MENU key to move to the next screen.

Screen 4: Cycle Count
The second screen shows the number of cycles which the SLS Lab Pro ultrasonic
bath has run since new.
The cycle count shows all cycles which the bath has begun and includes those cycles
which are not completed, i.e., those cycles aborted by the operator or because the
liquid level was low.
Screen 5: Low power
In its factory pre-set mode, the SLS Lab Pro ultrasonic bath will maintain the set liquid
temperature. This means that it is consuming power when sitting idle (i.e., when the
sonics are not running).
The SLS Lab Pro ultrasonic bath can be set to save power when not in use.
Setting Low Power to ON means that after five minutes of inactivity, your SLS Lab Pro
ultrasonic bath will enter its SLEEP mode – the screen illumination will power down,
and the internal water heater will not operate.
The SLS Lab Pro ultrasonic bath uses less than 10Watts of power whilst in SLEEP
mode.
By setting Low Power to OFF, the SLS Lab Pro ultrasonic bath will maintain the set
liquid temperature, i.e., when the liquid temperature falls below the specified setting,
the heaters will automatically switch on, meaning the bath is immediately ready for
use when required.
When the desired option is selected, use the MENU key to move to the next screen.
