[Accrs-ho] HO Analog/DC operation for Fair

[Wayne Toigo]

Folks,

Here are a few notes for Analog / DC operation for Fair (1st shift on Wednesdays).

Here is the current analog operating Cab state:

                Cab 1 (left side of Dispatch panel) – Operational.
                Cab 2 (right side of Dispatch panel) – Operational.
                Cab 3 (Passenger yard panel, handheld mobile controller) – Operational.
                Cab 4 (handheld mobile controller) – Operational.
                Cab 5 (handheld mobile controller) – Operational.
                Cab 6 (handheld mobile controller) – Inoperative.

There is one working handheld controller currently plugged into the connection ports for Cab 3, 4, and 5. It is very important that each controller remain with it’s assigned cab. You may move the handheld controller to another connection port of the same number, but do not connect the controller to a different cab. In other words, always keep the Cab 3 handheld with a Cab 3 port, the Cab 4 handheld with a Cab 4 port, and the Cab 5 handheld with a Cab 5 port.

The reason for this is that some years ago, MRC changed the wiring for the handheld controllers. If you plug in a new-style controller into an old-style power pack (or and vice versa), the rotating speed control knob will behave backwards (full clockwise produces 0 speed and full counter-clockwise will be full speed). Unfortunately, the handheld controllers themselves look identical. We have a mix of old-style and new-style power packs. I’ve sorted out the controllers to work with their specific Cabs.

So the easiest thing is to keep each controller with their current assigned cab.

Sorry if this is a bit complicated. Let me know if you have any questions. I plan to be attending all analog shifts.
