LIMIT CONTROL ADJUSTMENT
This procedure will reset the stop positions for the “up” button and button 1. If you have a wall switch with just two T6
connectors on the bottom you will need to use a separate 3-button switch for this operation. Otherwise you will use the
wall switch that controls the bus interface unit. Below is a diagram of switch you will use.
1. Remove cover screw from bus interface unit located on the motor end of screen case.
2. Locate the T4 wires coming from the motors to the bus interface (see wiring diagram).
3. Unplug the T4 wire of the motor to be adjusted from the bus interface unit and plug it
into the top left RJ22 4-pin connector of wall switch.
4. Locate the 3-position dipswitch in top right corner of switch. To adjust the down limit
flip the switch in the down direction. Press and hold the 1 button on the switch to run
the screen down to the desired position. Release the button to stop the screen.
NOTE: If you push the down button and the screen runs in the up direction press and release the
stop button. Then press the down button again. This should reverse the motor.
5. When the screen is at the desired location flip the dipswitch back in to the middle position.
6. To adjust the up limit (the screen should be in down position first) flip the dipswitch to the up direction. Press and
hold the up button to run the screen to the desired top position.
7. When the screen is at the desired location flip the dipswitch to the middle position. Now press 1 button to make
sure the screen stops at the new down position. Then press the up button and watch carefully to make sure it
stops in the new up position.
8. Unplug the T4 wire from the switch and plu
g
it into the SAME location you unplugged it from the bus interface unit.
