A door operator for moving a door includes a motor for moving the door between opened and closed positions, an operator for controlling the operation of the motor, and a switch, such as a wired wall station or a remote transmitter, for enabling the operator to control operation of the motor. Pushing and releasing the switch results in the operator allowing the motor to apply a normal range of torque values, and wherein pushing and holding the switch results in the operator allowing the motor to apply a broader-than-normal range of torque values. An external safety device coupled to the operator may be used with the operator. If the external safety device is enabled and the door is closing, the motor allows application of a higher-than-normal range of torque values. The door operator may also take corrective action if excessive door speed is detected. But, this corrective action can be overridden if the switch is held closed for a predetermined time.
