Hi Peter. Something I learned when I added a booster was don't forget your contact tracks that feed back to your S88 or in my case my ESU LokDetectors. Make sure the power supplying those units match up with the power blocks for your booster. I don't know what you are using for occupancy detection but if it is via contact tracks pay attention to the power supply.
Why should this matter? Sensing with contact tracks is just a measurement of whether the two outer rails are connected or not. The track power in the middle rail is not relevant for this. I must have misunderstood something.
I am using an ECOS and ECOS Detector so perhaps using a CS3 and S88 is different. If you have your ECOS Detector monitoring contact tracks being fed by the booster and by the main controller and both contact tracks are in use you can get a short. That is why in the manual for the ECOS Detector on page 9 it says:
In the example shown in figure 8 both
feedback groups “A” and “B” are supplied by the same booster. Therefore the terminals “0” and “B” on both sides of the ECoSDetector must be connected with each other. If you use a separate
ECoSBoost for group “B” (feedback inputs 9 through 16) then the module must be wired as described in chapter 6.4.
6.4 says:
The feedback inputs of the ECoSDetector are divided into two
groups: “A” (inputs 1 through 8) and “B” (inputs 9 through16).
These two groups can be supplied by two different booster sectors. Each feedback group has terminals “B” and “0” to be connected to the booster outputs that supplies power for the track
sector to be monitored. In figure 9 we show an example of how to wire a 3-rail system where both feedback groups receive power from their own separate power supply (group “A” form the ECoS and group “B” from a separate ECoSBoost.
Hi Chris and thanks for the info. I don't use the S88, it's the M83, my error earlier. sorry. I don't have to separate the brown wires. It states that in booster instructions. Also, I use
contact tracks but only the momentary ones with the rocker in the center which allows for bi-directional traffic. Cheers, Peter.
