Z-Stuff DZ-1220 Trolley Control

Sounds like a bad input connection from the sensor to the control.

Try disconnecting all the track sensors and activate  the inputs one at a time.

I think you need to ground the B terminal to trigger the stop. ( but check

the diagram anyway ) If it works, connect sensors one at a time, could be a bad sensor or a pinched wire....

Bruce..

Call Dennis Zander.(DZ).  Great to talk with.

Bruce,

The 'sensors' are just the cut or insulated outer rail of each designated track section. The DZ-1220 'senses' when the trolley or car wheels connect or jump the track power common (the other outer rail) with the cut rail, and all of these are fine. The wires from the cut rails are connected together to Mid-B, and each time the trolley advances to the next track section/sensor, it triggers the next station announcement, until the last one, which is designated as the end point of the loop. This last one is connected by itself to the controller East-B.

Jim,

I called Z-Stuff and left them a message. Hoepfully I will hear from them tomorrow.

Thx!

I use a little different setup. I'm doing a loop, I use a dwarf signal to start

the whole process, Trolley stops in front of the MTH station with disapearing

passengers.  so trolley stops, People disappear or re-appear, announcement is

made. Trolley goes on it's way.

Anyway this may sound obvious but have you tried a jumper wire at each block

to simulate the trolley ? I'm thinking dirty wheels.

I did the same thing on our club layout, but dirt is a big enemy, also the newer

trolleys with the light weight and traction tires don't help either..

I ended up using relay's with capacitors across the coils to eliminate the problem.

Oh while re-reading your post I ran into a bit of a quirk with my loop announcements.

when energized the first stop could not be the middle for some reason. It had to be

the E sensor. So when I start, I move the wire to E, after the first stop I move it to

mid and leave it there, Then the announcements rotate. I'm not sure why but it might

be something to try.

When working it's a great addition to any railroad.

Keep at it, it's worth the effort...
