The Swingmaster uses a DC motor and gear-reduction system (the operator) to drive an arm system
that opens the door. Closing power is provided by coil spring. An electronic control unit uses a cam
door positioning system to control the door's movement.
Note: One control unit required per operator.

When the control unit receives an opening signal, the door is opened at the Swingmaster's high
speed. Before the door is fully open, it slows to low speed. The motor stops when the operator
reaches the full open stop. The motor holds the open position. If the door is obstructed while opening
it should stop (adjust the HLD potentiometer accordingly). Once all signals (or similar wording)
have cleared and the time delay has expired the door will reverse to the closed position. The force
that it takes to stop an opening door is adjustable from 12 to 25lbs depending on door widths and
speeds.

When the time delay expires, the Swingmaster will close the door automatically using spring force
only, and with the motor acting as a brake. The door will slow to low speed before it reaches the
fully closed position. The door is kept fully closed by spring force.
