ADJUSTMENTS
3.
The following procedures will be used to adjust each module's detection zone upon power-on, and must be made with the
Background Analysis jumper set to 'Normal Mode' (see page 5).

MODULES
MONITORING &
NON-MONITORING
When using monitoring and non-monitoring modules in the same chain, observe the following rules:
COMPATIBILITY

SuperScan-T does not work
SHOOTING
at all.
No LED indications.
SuperScan-T output appears
to be working opposite of
what is expected.
Door stops by itself before
reaching the full-open
position.
Activation or safety is being
held triggered.
Erratic detection behavior is
occurring throughout the
door's opening and closing
cycle.

a.
Power the sensors with 12 – 24 VAC/VDC ±10%. LED status should reflect what was configured for the relay output
(see page 6)
b.
Use a white, gray, or black piece of cardboard about 8" x 11" and hold it as shown in the diagram in step 2 of this
section (previous page).
c.
Move the cardboard from the floor upward until it is detected. This will determine the height of the inactive area (B
distance).
d.
Measure the height at which the cardboard was detected.
e.
If this height does not fall between 12" – 16" above the floor or does not meet your requirements, an adjustment must
be made to the detection distance. One notch of the distance adjustment corresponds to approximately 4".
-
If Zone B is too high, turn the distance adjustment clockwise to increase the detection distance and decrease
Zone B.
-
If Zone B is too low, turn the distance adjustment counter-clockwise to decrease the detection distance.
Per current ANSI A156.10, 156.27 the detection zone must be within 28" of the floor. Ideally, each detector should
be adjusted so that detection occurs at 12" – 16" above the floor. Less than 12" of Zone B may result in occasional
false triggering of the sensor.
f.
Once all sensors have been adjusted, activate the door several times and allow it to go through a full cycle each time.
Ensure that no false triggering is occurring, as would be indicated by the door re-cycling or stopping by itself at any
point of travel.
g.
Ensure compliance of all applicable safety standards (i.e. ANSI A156.10, 156.27).
h.
Install all remaining covers, endcaps, screws, etc.
• Non-monitoring Master modules CANNOT be used with monitoring Slave modules.
• All other combinations will work; however, for a system to utilize monitoring, all modules must be monitoring modules
POSSIBLE CAUSE
Faulty power supply
Faulty connections
Relay output may be configured
improperly
Safety-side SuperScan-T may be
seeing an adjacent wall or rail behind
the door near the open position
SuperScan-T detection module may
be seeing the floor or unwanted
object near door
Possible faulty wiring at door transfer
location
Detection Distance Adjustment
CORECTIVE ACTION
Power supply must be 12 – 24 VAC/VDC ±10%.
Check for this power at terminals 7 and 8 of the affected
SuperScan-T module.
Observe the LED indications on the affected modules to help
determine status.
Observe the LED status on safety side of door. Find the
SuperScan-T module that is being falsely triggered. Check
for:
ü
Proper detection angle
ü
Detection range adjustment
SuperScan-T may need to be inhibited at a specific point of
door travel at the safety side for proper operation. Refer to
the terminal connections on page 4.
Reduce the detection range on the affected module(s).
Detection should occur at 12" to 16" above the floor. Refer to
step 3 in "Mechanical Adjustments – Positioning & Angling
Modules" (above).
Using a multi-meter, check each wire for continuity at the
transfer location. Move the wires around during testing to help
locate any breaks. Replace faulty wiring as necessary.
