Standard Operating Modes
This section describes the standard operation of the control board with the factory set default values.
Motor Control
The controller drives the motor in the direction determined by the control inputs. Once a cycle is started the motor will continue to travel until:
1. The controller is instructed to stop by a control input; or;
2. The travel limit of the opener is reached; or,
3. The motor is obstructed, overloaded or stalls. When the control inputs instruct the control board to change the motor direction, the controller brakes the motor, waits for the door to stop moving and then starts the motor in the opposite direction.
Motor Obstruction Detection
If the door is obstructed while opening, it will stop. If it is obstructed while closing, the door will stop and then reverse to the open position. Obstruction detection monitors the motor’s speed and compares it to the “normal” speed profi le for the motor. If the speed of a motor falls below “normal” then the motor is said to be obstructed. In addition to the normal motor obstruction detection, motor overload and stall detection is provided to protect the door and opener.
