ACS2 & BPC2 Issues

@Matt V posted:

I am new to this forum and have recently upgraded my Christmas train to a full legacy system. I have a two loop railroad with separate power masters(both set @ 180W) along with 180W power house supplies. Naturally I have a #990 legacy system controlling everything. Each loop is isolate and are functioning fine. I have a Legacy engine, two conventional old Lionel engines and one MTH Diesel engine with photo sound 2. My Lcs set up has the WIFI module, BPC2, ACS2 and two LCS track sensors(one for each loop). I have two coupler/operating tracks, a barrel loader/unloader, and operating control tower. I have the track loops programmed no problem, all switches are command switches so they are all programmed, Lcs sensor tracks are set, my issue is with my two LCS modules. I also have a CW-80 Transformer to power the accessories which is set at 14V. Both the BPC2 and the ACS2 have been programmed. I have power to the relay side from my powermasters. The common power comes from one of the powermasters for the BPC2 and from the CW-80 for the ACS2. They both programmed no problem but I have no power to the two sidings i have connected to the BPC2 and no power to the 6 accessories I have connected to the ACS2. On the relay side when i give the proper commands I here the relays functioning and the red light illuminates but nothing happens on the other side. I have three distribution blocks in the system one for each loop and one for accessories. Common (U) hooked up to each loop from the 990 and commons from the operating tracks to the appropriate blocks. I have also isolated both sidings from power. I assume the commons(U) do not need to come back to the distribution blocks as once the sidings are powered up the commons are not isolated. Any help is always appreciated.

Matt welcome to the forum!  There are a couple of things to verify.

1) Are the PowerHouse transformers phased with the CW-80?

2) The sidings do need connections to power Common.  The BPC2 only switches the Power Hot side.  Are the sidings getting  Common connections either through a Common bus wire or via outside rail connection or both?

If the answers to both questions are yes, then if you were to draw and post a diagram showing your power and control connections, this may be more revealing of the issue.

So no I did not put the PH transformers and CW-80 in phase? Did not know it was needed

As i mentioned I have three distributions blocks

Block 1) Powered by  CW-80 for accessories and both COMM terminals on ASC2 module. This block also has common (U) from both coupler/operating tracks, barrel loader, and operating tower. So all accessories have a common (U) hook up direct to block

Block 2) Simple - one Powermaster and Loop #1(A&U) Legacy base com (U)

Block 3) One Powermaster and Loop #2 (A&U) Legacy base com (U), COMM terminal from BPC2 power from siding 1 & 2 to BPC2. I have no direct connection from (U) from both sidings. I assumed the circuit would be complete when the sidings were turned on from BPC2 as they run from the two Loops.

Naturally both Powermasters each have a Powerhouse 180 connected to them

As a side note as of yesterday when i went to turn on my Legacy base it did not work no lights or a connection to the Cab 2. That is now another issue I will take up with Lionel Monday morning. This in turn has restricted me from trying to figure out what is wrong with the connections on the two LCS modules.

Thanks Again Steve

Matt I'm sorry for your troubles.

Phasing all the transformers connected to one's layout is very important because out of phase transformers can combine voltages additively ( 18 + 18 = 36 volts). Here's a good tutorial on phasing transformers written by @MartyE

Unfortunately I'm unable to visualize all of your connections from your text descriptions, there seems to be some missing and incomplete descriptions of your connections.  Without more details or an accurate diagram, I am unable to offer any other suggestions at this time.  Drawing a diagram is often helpful in revealing wiring errors and it may also help me and others better understand the cause(s) of the issues you're having.

Thanks Steve will work on a schematic and read the tutorial
