On page 5 in this pdf https://viessmann-modell...67/5132LWKqqUnEFE6eo.pdf you have a diagram for connecting it.

Hi
Having one of these I found that, you need either to operate them manually or automatically (see below)
Manual operation
Basically one activation makes the water crane turn toward the loco without any stopping unless you stop pressing the button.
In the other direction, the water crane stops when it is in its rest position
This is done by a conventional command

Digital Operation
- you need first program the crane to teach it which address and which protocol you want
- then you may use a software (Rocrail in my case) to make it rotate at the appropriate angle (side on the loco or center).

Create an Action to command the crane active for 1.8 seconds (to place the crane laterally) or 2.6 Seconds (if the crane shall be positioned in the center of the tender.
Here is a small video about its operation

Cheers
Jean

Hi Jean,


Your water crane operation is exactly what I want to achieve using Rocrail. Right now I have it functioning so that after the loc is in the block, the crane rotates its default 90 degrees. This is fine for most of my locos, but not all where in some cases the crane needs to rotate less or end up hitting a higher obstruction on the loco. I note that you said that you accomplished this by using an Action to set a timer. Can you please provide a few more details as to how you accomplished this for individual locos within the Route?

Many thanks
Peter

Hi Peter
This is a Viessman model 5132.
Normally this is a manually operated crane with 2 controls: 1 brings it back home and the other makes the cran rotate until you stop pushing
Using Rocrail I have configured one Action to move it to the side of the loco during 1,86 seconds.
Another Rocrail Action brings it to the center of the loco with an activation during 2.59 seconds, all depending on the tender type.
The loco type is recognized by Rocrail so a loco-specific command brings it at the proper location to load water.
Cheers
Jean

Thanks Jean.

Pardon my confusion, but are you saying for each of your 2 Actions you are listing the locos that apply to each Action within the Constraints?

Actions within Rocrail have never been my strongpoint!

Hi Peter
I was not very clear. So let me try be clearer.

There are 2 actions to rotate the water crane sideways or in the track center

Each loco, when entering the Block near the water crane is starting its own action to position it.
These are XML small programs
Below is one of the commands for the 241 A 65 loco
Basically the program forces a loco speed until a sensor is reached (fb210)
The purpose is to defeat the normal stop order by the block and to impose an "overshoot"

Then it forces a lower speed (28) for 28 loops at 100 ms
Then the inertia is cancelled and the loco is stopped abruptly
Finally the loco is reversed (swap) so that it will be ready to return to the TT

By adjusting the speeds and timer for each loco, a precise stop may be obtained
Cheers
Jean
