The AdControl can be used if a RollerDrive EC300 (predecessor of EC310) is to be replaced with a RollerDrive EC310. The AdControl has a short connecting cable with plug. The plug corresponds to that of the EC300 and is connected with the existing DriveControl EC200/EC300 or extension cable. The EC310 is inserted on the left side. DIP switches are protected by a yellow end cover. The DIP switches can be used to set the gear stage of the previously used EC300 and the new EC310. The complex wiring of a new control is not needed. The use of the AdControl allows using a RollerDrive EC310 without changing the existing wiring. Depending on the gear ratio, the AdControl can also be used when replacing an EC200 with an EC310 (see instruction manual of AdControl).
