5. Press the "Open Door" button on the Remote Control.
NOTE: If a different travel distance is required see "Door Travel
Adjustment below.
ADJUSTMENTS
Adjust Door Travel Distance
To adjust door travel distance:
1. Press and hold the activator button on the front of the motor
box for 13 seconds.
The Status Light on the front of the motor box will begin to blink
alternately red and green. When this starts to happen release
the Activator Button. When put into "Learn Moden the system
runs back and forth several times and measures its
environment, such as open and closed locations etc. The
system will then stop and remember these learned
measurements.

System Controls and Indicators
Learn Mode
The CM6DH system has no limit switches. The system uses an
encoder on the motor to collect data and send it to the micro
processor’s memory. The software "learns" about its
environment (speed, time duration, stop points, etc.) during the
initial setup of the unit and retains that information until
requested to "relearn" its environment.
The unit is shipped pre-set from the factory and will then
continually adjusts to it’s enviornment on each activation.
If for some reason you want to place the system into “Learn
Mode” (such as to stop at other than its normal stop points),
Press and hold the red activator button on the front of the motor
box for approxamatly 13 seconds and then release it when the
Status Light flashes quickly red, green, red, green, red, green.
Figure 12
The controller will then be in “Learn Mode” (The door will move
for 3 seconds, stop for 10 seconds, and when it starts moving
again it will be in it’s “Learn Mode”).
When put into “Learn Mode” the mechanism runs back and
forth several times and measures it’s environment, such as
open and closed locations etc., and then stops and remembers
these learned measurements, so that next time the system runs
it knows where to start and stop.
Status Light Codes
There is a light on the front of the mechanism motor box that
will tell through its pattern of flashes and colors what the
mechanism is doing.
Figure 13
Normal Doors At Rest - The Status Light will be on steady
green.
Normal Run Motion of Doors - The Status Light will flash in
groups of 2 green followed by a pause. In normal run motion
the doors on the system have a variable speed. The doors will
start slowly, accelerate to a fast speed, and then slow down
before coming to a stop.
Doors Obstructed - The Status Light will flash in groups of 3
red followed by a pause. If the doors meet an obstruction they
will sense the obstruction, stop momentarily, and move in the
opposite direction for a few seconds. ---- Remove the
obstruction and then activate the doors. They should return to
normal run motion.
Doors Obstructed Both Ways - The Status Light will flash in
groups of 4 red followed by a pause. Similar to Doors
Obstructed but doors are prevented from moving in either
direction. ---- Remove the obstruction and then activate the
doors. They should return to normal run motion.
Travel Too Far - The Status Light will flash in groups of 5 red
followed by a pause. The motor is running but the doors are
not moving. ---- Has the motor box been uncoupled from the
