UPC20+ Universal Power Controller
Control Options Modes
Motor Control mode
The table list options and connections for motor control. DIP switch settings provide 1, 2 or 3
button remote control contact arrangements. This mode is typically used for screen and drape motor
control.
In motor control mode, only one power relay (motor) can be energized at a time. When switching
from one direction to another, the first motor is automatically turned off and a half-second delay is
inserted before the other motor will turn on.
Once a motor is turned on, it will automatically be turned off after the amount of time determined
by the motor time delay potentiometer, R8. Delay time can range from 0 to 90 seconds. It is
typically set to allow direction limit switches to operate, or to reach the desired position.
 Single Button Mode operates with one pushbutton in a sequence: Up, Stop, Down, Stop
and so on for each successive button press.
 Two/Three Button Mode operates with two pushbuttons, one for Up and one for Down.
 Momentary On/Off operates only when the button is pressed.
If UPC20+ is powered up when changes are made to Dip Switch settings, then power
must be cycled before changes can take effect.
