Sensor detecting
erratically or false
activations
1. Not properly grounded
1. Verify continuity between sensor ground and
earth ground. See Application Note for details.
2. Unstable power supply
2. Be sure to use the BEA isolation module
3. Electrical noise within sensing zone
3. Reduce sensing zone (potentiometer
counterclockwise)
4. Non-stationary object within
detection zone
4. Clear 10’’ zone around detection field
5. Sensor has been vandalized
5. Verify sensor is operational; replace if necessary
Sensor not
detecting
1. Sensing zone is set too low
1. Increase sensing zone (potentiometer clockwise)
2. No power
2. Verify power supply and connection

INSTALLATION (continued)
11) Reinstall back of NEMA 4 enclosure
12) Reassemble (align, push in, slide down) faceplate assembly to mounting ring
13) Reinstall two (2) set screws
14) Test installation functionality and performance

FUNCTIONALITY
ACTIVATION - Activation signal held until sensing zone is cleared (or until relearned). Audible Alert
(if enabled) will pulse for 0.5 seconds at initial detection.
REJECTION - An object must be within sensing zone for at least 130 milliseconds for detection to
occur (i.e. parallel traffic rejection).
TRACKING - Reduced unwanted detections by allowing small variations in baseline capacitance (i.e.
temperature/humidity changes). If stationary object remains within sensing zone for more than 5
seconds, a new capacitive zone will be learned and normal operation will resume (i.e. chewing gum
stuck to faceplate).
Upon completion of the installation or service work, at a minimum, perform a daily safety check in accordance with the
minimum inspection guidelines provided by AAADM. Provide each equipment owner with an owner’s manual that
includes a daily safety checklist and contains, at a minimum, the information recommended by AAADM. Offer an
information session with the equipment owner explaining how to perform daily inspections and point out the location of
power/operation switches to disable the equipment if a compliance issue is noted. The equipment should be inspected
annually in accordance with the minimum inspection guidelines. A safety check that includes, at a minimum, the items
listed on the safety information label must be performed during each service call. If you are not an AAADM certified
inspector, BEA strongly recommends you have an AAADM certified inspector perform an AAADM inspection and place
a valid inspection sticker below the safety information label prior to putting the equipment into operation.

CAUTION: When installing near unprotected and/or uninsulated circuits, additional
electrical isolation may be needed. The shrink tubing provided by BEA over the printed
wiring board is rated minimum 150V, VW-1 and 80oC. This information may be taken into
account to define whether additional isolation is required.
