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.

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.

Status Indicator

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
