DC Tubular Motors: Motor Programming for Motors Without Built-in Radio

Applies to these motors: TMDC-12-25-15-28-NR, TMDC-12-25-07-34-NR, TMDC-12-18-03-25-NR

1. Preparing the RollerTrol™ motor:

Figure 1: Programming Hole

Each RollerTrol™ motor has a a small hole on the outside edge of the cap at the wired end of the tubular motor. At the bottom of the hole is a small switch for activating the 'programming' mode of the motor.

You can feel a pronounced click when this switch is activated, when inserting a small screwdriver or similar item into the hole. You do not need to apply much pressure for this to be activated. Your motor should be mounted in a position that allows access to this hole.

2. Check Wiring Polarity:

Figure 2: Wiring

A DC motor of this type reverses direction when the polarity is reversed. Connect your rocker switch or controller to the motor and activate the 'up' mode of motor operation. If the motor rotates in the wrong direction, reverse the wiring to correct this. If you do not have a switch for operating the motor, please see this article:

3. Setting the Upper and Lower Travel Limits:

The travel limits of these RollerTrol™ motors can be set and changed at any time . The sequence is as follows:

Activating the Programming Mode:

• Activate the motor in either direction with the Up or Down button; while the motor is operating, insert a screwdriver in the programming hole described in step 1 and hold the setting button down for approximately six seconds until you hear 3 short beeps. Stop the motor. At this point, the motor has entered into its limit programming mode.

Setting the Upper Limit:

• Activate the Up direction of the motor until it gets close to the desired upper limit point. Stop the motor, then press the Up button again; the motor now enters the 'Jog' mode. You'll see the motor move in very short steps that are a small fraction of a full rotation. Alternate between Up and Stop modes until your motor is at the exact upper limit you desire.
• The upper limit has been set at this point, and the motor is still in 'programming mode' so that you can set the lower limit.

Setting the Lower Limit:

• Press the DOWN button until you hear 3 short beeps, then continue holding the down button. After 2 seconds the motor will move in the down direction at normal speed.
• When it gets close to the lower limit, press the STOP button. The motor now enters the 'Jog' mode. You'll see the motor move in very short steps that are a small fraction of a full rotation. Alternate between Down and Stop modes until your motor is at the exact lower limit you desire.
• To exit the programming mode, press the Up button and continue holding it until you hear the 3 'short beeps'. At this point, the motor has been set and the motor is now back in normal running mode and you should be able to test the full excursion. Repeat the above steps if you need to reset the travel limits.
