Adjusting the Level Sensor
Warning!
Pay attention to the relevant safety regulations when working at the open controller.
Notice
The level sensor must be adjusted
according to the type of product used
and the size of the bottle in order to
function properly.
• Loosen the (3) reservoir knobs 2 and
remove lid 1.
• Remove the screws and open the
housing.
• Empty a bottle of the product you use.
• Leave as much residue in the bottle as is required in order to prevent air getting into
the product feedline.
• Insert the product bottle. For small bottles use bottle nesting block 14.
• Check that the product bottle inserted into the bottle-nesting block is pressed against
the level sensor. Only then the correct adjustment of the level sensor is possible.
Notice
For product bottles, which do not fit into
the bottle-nesting block, rotate the level
sensor out or in so that it clamps the
product bottle.
If necessary, press the product bottle
with a suitable aid against the level
sensor.
• Switch on the power switch 5.
Warning!
Pay attention to the relevant safety regulations when working at
the open controller
• For 250 ml product bottle, pay attention
to the correct position with respect to the
level sensor.
• Remove the plastic cap from the level
sensor.
• With an electrician's screwdriver, find
the point at which the sensor switches to
the condition inactive. The yellow LED
extinguishes.
Notice
The correct adjustment is exactly the point when the sensor switches off.
Do not go beyond that point!
• Check this adjustment with a full bottle and an empty bottle again.
• Close the housing. Insert and carefully tighten the screws.
