McFadden Digital Control Loader Upgrade

Servos & Simulation recently upgraded the digital computer and interface system to a McFadden Hydraulic Loader. The process involves removing the digital computer and interface box and replacing it with our Digital Control Loader and Interface Unit design specifically for this job.

The new controller is all digital. There are NO POTS. All variables in the flight control model are floating point in engineering units. The flight control model is written in Borland C++. The balancing of the force transducers is done automatically by software. The first replacement controller was installed on March 2001 and has performed flawlessly.

The upgrade process is simple and effective. Included in the upgrade is:

1. A New Digital Control Computer - This is our standard system. We can operate up to five axis with this system. This system cables directly to the Interface Unit.

2. A New Interface Unit - This allows our system to interface with the McFadden loaders. The original cabling for the McFadden loaders interface directly to this box.

3. One Replacement Cable between the S/S/I box and the Interface Unit. Connector change is required, but the connector number remains unchanged.

We have produced a fully updated COTS manual that incorporates the old McFadden COTS manual and our standard COTS manual into one book. There are some drawing revisions that are part of the package, but all of the remaining original cables in the system integrate directly to our system. Governmental revisions to the system have been kept to a minimum.
