Red
0.7 s
2 times
Blinking twice (0.1 s
interval) (0.7 s unlit)
Wiring error
One of the wiring errors below with OC-907C T.
Activation output (Yellow wire), stall output (Green wire), test input (Pink
wire), BodyGuard or motor voltage input (Red wire), close switch input
(White wire).
Displayed if the necessary wiring for auto configuration has been
judged incomplete, or if the wiring is temporarily disconnected during
operation.
Orange

Blinking twice (0.1 s
interval) (0.7 s unlit)
Communication error
List of symptoms/causes/countermeasures
Symptom
Possible cause
Possible countermeasures
Auto configuration will
not start
OC-907C T indicators are not
solid
Improper power supply
Correct power problem.
Power harness connection is unsuitable
Connect the power harness correctly.
OC-907C T indicators blinking
Orange twice (communication
error) and no indicators solid on
OA-607 T
Loop harness connection is unsuitable
Connect the loop harness correctly.
Pass through harness connection is
unsuitable
Connect the pass through harness cor-
rectly.
Loop harness or pass through harness is
disconnected
Replace as necessary.
OC-907C T indicators blinking
Orange twice
More than two OA-607 T have been con-
nected per door
Refer to Wiring and connect OA-607 T
suitably.
OC-907C T/OA-607 T indicators
blinking Blue
OC-907C T dipswitch setting is incorrect
Check OC-907C T dipswitch setting.
Auto configuration
failure
After executing auto configura
-
tion, OC-907C T indicator blinks
Orange twice (wiring error)
Activation output (Yellow wire) is not con-
nected correctly
Refer to Wiring and connect activation
output (Yellow wire) suitably.
Stall output (Green wire) is not connected
correctly
Refer to Wiring and connect stall output
(Green wire) suitably.
After executing auto configura
-
tion, OC-907C T indicator blinks
Orange (0.5 s intervals) (setting
error)
Automatic recognition (door angle infor-
mation, what configuration and position
sensors are installed in) fails because door
does not operate smoothly
Set installation positions individually with
the setting app.
Intermittent recycle (ghosting) or intermittent stalling
After initial setup door ghosts several times
on first activation
Happens in 15% of installations; stopping
after first activation means system is OK.
OA-607 T sensor head not mounted flush
on door
Head may be resting on top of door loop
cover; reposition head flush on panel.
Improper threshold or swing area angle
adjustment
Set threshold and swing area angles at +5
degrees (Deep).
Motor voltage input, BodyGuard input, or
close switch input is unsuitable
Refer to Wiring and connect motor voltage
input, BodyGuard input, and close switch
input suitably.
Stalling caused by traffic just outside of
swing path or objects near guide rails
Adjust the detection area via area depth in
the setting app.
OA-607 T dipswitch door width setting or
setting app area setting is unsuitable
Verify proper settings.
Objects that move or emit light in the
detection area
Remove the objects.
The detection area overlaps with that
of another sensor
Change the OA-607 T frequency setting
with the setting app.
Water droplets on the detection window
Install in a location protected from water
droplets.
Sensitivity is too high
Set the sensitivity lower with the setting
app.
Raining or snowing
Enable immunity or snow mode from the
setting app.
No activation and/or no
reactivation on closing
cycle
OA-607 T sensor detects (solid or
blinking Red indicator) (flashing:
1st row detection, solid: 2nd/3rd
detection) but door does not open
Improper connection of OC-907C T (Yellow
wires) to door controller or ON/OFF/hold
switch
Verify proper connection and output of
activation output (Yellow wires).
On Knowing act applications poor or
improper connection of knowing act input
(Purple wire) from OC-907C T to the activa-
tion device
Verify proper connection.
Auto configuration failure (configuration
recognition failure) or incorrect setting
Check the suitable settings with the setting
app.
OA-607 T no detection (indicator
solid Green) (stand-by)
Sensitivity is too low
Set the sensitivity higher with the setting
app.
OA-607 T detection window is dirty
Wipe the detection window with a damp
cloth.
OA-607 T indicator is blinking
Orange (configuration error within
setting error)
Auto configuration is incomplete
Execute auto configuration (hold down
function switch for 2 s or more).
OA-607 T indicators are blinking
Red and Yellow alternately (in-
complete)
Power went off immediately after auto area
learn completion (before auto-saving the
settings)
Execute auto area learn (press function
switch briefly).
Door failed to open due to obstacle during
auto area learn
Remove the obstacle and then execute
auto area learn (press function switch
briefly).
