Description:
Relay Tol.
This sets the tolerance the controller uses for the signaling relays.
Example: If the Fully Open position is set at 700 and Relay
Tolerance is set to 30, the DG-Mini will activate an appropriately
programmed relay when the position reaches 670.
DC Brake Cur.
DC braking is used to inject DC current into the motor windings
which help stop the door within the position tolerance at the end
of travel.
DC Brake Time
This is the duration of time DC current is injected into the motor
after it has stopped.
Note
In applications where the ambient temperature is below 0°C / 32°F the controller can be
configured to provide a constant DC current to the motor to prevent frost:
•
Set DC Brake Time to 100 for constant DC Brake.
•
Set DC Brake Current according to the desired temperature rise.
