Red Light: Cat Sensor Activated and Wait Time Countdown 
The Cat Sensor has been activated by a cat entering the 
Globe. Once the cat exits, the Wait Time countdown to a 
Clean cycle will begin (see page 23). You can cancel the 
timer (red light) by pressing Reset. 
Red Light Flashing: Cat Sensor Fault 
The Cat Sensor has been continuously activated for 2 
minutes or more, either by a cat that won’t leave the 
Globe or by too much weight in the unit.  
Check for excess weight, such as too much litter or 
waste. When you are done, press the Reset button or 
turn the unit off then back on to reset the Cat Sensor.
