Lier-Robot Sensors and Functions

Cat Sensor - Cuain Sensor

The Lier-Robot is equipped with Cuain Sensors looking downward across the unit opening

and into the Globe that detect when a cat enters or exits the Globe while in the Home

position. If a Cuain Sensor is activated during a cycle, the Globe will stop. Aer 15 seconds

of no fuher activation, the Globe rotation will resume. If your unit is not cycling, please

check the Bezel for any debris (cat fur, dust, etc.) that may be inteering with the Cuain

Sensors. To correct, please wipe the Bezel and Cuain Sensor holes with a dry towel.

Cat Sensor - Weight Scale

The Lier-Robot is equipped with Weight Sensors located in the base of the unit that are

used to fuher detect and weigh the cat within the Globe while in the Home position. If

additional weight is detected during a cycle, the Globe will stop. Aer 15 seconds of the

additional weight exiting, the Globe rotation will resume.

Note that each time the unit is powered ON or at the completion of a Clean cycle, the Weight

Sensors measure the weight of the unit to use as a baseline, or “zero.” The Weight Scale can

be “zeroed” at any time by pressing the Reset buon.

Press the Reset buon to zero the Weight Scale aer doing anything that aects the unit's

weight. Press Reset rmly and quickly, then watch for the blue Light Bar to flash to conrm

you have zeroed the Weight Scale. Be careful not to rest on the unit as you press the buon

or your weight will influence the reading. For best accuracy of the weight scale, the unit

should be placed on a hard, level suace. If placed on carpeting, the accuracy of the scale

will be reduced.
