Section 8
Verification of Operation
1. After mounting, setting parameters and applying
power, walk test unit to verify detection pattern.
2. If the sensor does not function as expected, TURN
OFF THE POWER and RECHECK the Depth Adjustment
Lever Arms, Dip Switch and Width Mask Knobs as
described in Sections 5 and 7.
3. After rechecking, if there is still a problem, adjust the
sensitivity.
*****EXTREMELY IMPORTANT*****
After final set-up, test unit(s) completely to ensure that
proper coverage has been achieved (width, depth and
location of the pattern must be tested).
After the installation and operational check of the
system:
1. Place the proper labels on the door per all applicable
standards.
2. Instruct the owner of the door system operation and
how to test it. This should be checked on a daily
basis.
3. Instruct the owner on what to do if the door or any of
its components become damaged.
4. Strongly recommend to the owner that the complete
entry be inspected twice a year as part of the service
agreement.
Section 9
Troubleshooting
PROBLEM 1: Door does not operate
CAUSE 1: Sensor Connector.
SOLUTION 1: Tighten connector or reconnect.
CAUSE 2: Power Supply.
SOLUTION 2: Check that the power supply is properly
connected and 12V to 24V AC or DC.
PROBLEM 2: Door operates intermittently.
CAUSE 1: Sensor is very dusty or covered in water
drops, etc.
SOLUTION 1: Clean the sensor (do not use thinner or
alcohol to clean sensor).
CAUSE 2: Detection pattern is incorrect.
SOLUTION 2: Set the proper detecting rows using DIP
SW, Depth Adjustment Lever Arms and
Width Mask Knobs.
PROBLEM 3: Door opens & closes halfway repeatedly
(by hunting door movement).
CAUSE 1: Detection row "ROW 1" is focused too
close to the door.
SOLUTION 1: Set the Lever Arm of inner 3 rows away
from the door. Or turn down the
sensitivity with sensitivity adjustment
knob.
CAUSE 2: Detection pattern is incorrect
SOLUTION 2: Set the proper detecting rows using DIP
SW and Depth Adjustment Lever Arms
PROBLEM 4: Door operates by itself.
CAUSE 1: Moving objects in detection area.
SOLUTION 1: Remove the moving object from the
detection area.
CAUSE 2: Outer 2 Rows are set too far from the
door.
SOLUTION 2: Set the Lever Arm for the outer 2 rows
closer to the door. Or reduce the
detection rows by Dip Switch so as not
to detect passing people.
CAUSE 3: Sensitivity too high.
SOLUTION 3: Turn down the sensitivity with Sensitivity
Potentiometer.
CAUSE 4: Another sensor is installed nearby.
SOLUTION 4: Ensure different frequency setting for
each sensor.
CAUSE 5: The condition of monitored area
changes suddenly. i.e.
Dusty/Dirty/Snow, mat laid etc.
SOLUTION 5: The condition of the monitored area can
change due to heavy dust or dirt, heavy
snow or footprints being left in fresh
snow. This may cause the door to
remain open. Set the "Presence Timer"
to a shorter time.
