(above) 2/11 - Trial fit of the hardware. The holes are marked, but not drilled, for the code meter and other reset/recall/coding light hardware.
(Left) 1/14/05: The frame, uncrated, dusty and dirty, and in the garage. Fresh out of the crate from Rod Loder out in Oregon.
|Installation of the code meter and code function hardware. These plates weres custom made by Mike Burgett of www.ctcparts.com. Thanks, Mike!||Picture of the wiring in progress. I got a good deal on several rolls of purple wire, which is why I used that color.|
|Rear of the machine showing the code equipment.
No electronics here - this is the actual code equipment from the original machine.
The 510 LC (Line Code) unit is on the shelf to the left, and an indication storage unit 'pup' is to its right.
The storage and route check relays are all in the large cabinet sitting on the floor.
The line and starting relays are sitting on top of the LC unit.
Click here to listen to an indication code cycle.
|The field location consists of an identical 510 LC unit (top left) and another pup (top right), KP application relays (bottom left), and the line/field relays (bottom right).
I am using a DirectLogic DL06 Programmable Logic Controller (hiding behind the KP racks) to simulate switch, signal, and lock movements, as well as route lock and checking and moving of a train thru the plant.
|Here's the coder unit.
The same coder is used in the office and field location
510 uses "progressive" delivery of controls and indications.
This means the control or indication is delivered the
instant it is received during the coding steps - where-as
older systems (502, 504) were all delivered at one time at
the end of the code cycle.
