LOW BATTERY DETECTION
• A red ashing light in the electronic eye indicates low batteries.
• A solid red light in the electronic eye and no water ow indicates the batteries
are dead.
• The user should change new batteries immediately.
POWER SAVING
• If the electronic eye (sensor) has not detected object motion within 30 minutes,
the controller will enter its lowest scan period of 1.4 seconds
• When object motion is detected, the controller will change the scan period
from 0.4 seconds to 0.7 seconds and change back to 0.4 seconds when the
object removed.
ANTI-INTEFERENCE SYSTEM
• Sunlight or other types of lighting may interfere with the distance sensing
range. In this case, the controller will compensate the sensing distance to a
safe range temporarily. The controller will adjust the distance to the normal
range when no interference is detected.
