A CDU works much better, can throw up to 10-12 switches at the same time, and will NOT burn up your switch machine. I believe they can be used on the LGB switches…I may be wrong. I KNOW a CDU works on Peco On30 switch machines, because that’s what I use. I use manual switches on my large scale stuff. Maybe someone else can be a bit more help.
Did you ever get this figured out? I’m working on expanding an old starter set with the same transformer and wanted to know if a new transformer will be needed to control the new switches.
You need more than a switch and a transformer, and I offer the following since I do not see you mentioning a controller
What is being used for a control?
The transformer output is A/C for accessories.
The EPL switch drive is a DC motor and needs a diode to control direction of the throw.
Lgb markets a control box that operates 4 epl drives, and a separate booster unit.
Aristocraft has the 55474 and 55475 remotes at 27mhz for controlling either 2 or 5 epl drives, or the Arsito dricves.
You can add a momentary switch and diodes to control the switch.
If you have the appropiate control unit, then I have 2 reasons the switch does not work properly.
motor jumped the gear inside.
Switch not level and jams.
To check #1, can you manually get the switch with the epl drive to travel all the way? A jumped gear will not allow you to do this, but an uneven switch will work manually.
