I recently purchased a DZ-1075 from my local Hobby shop. I followed the directions included and after hooking it all up soldering wires etc. it seems to only turn accessories on for 1 second. The sensor's LED is working properly. I hooked up 2 different accessories and it happens to both Lionel Banjo and MTH vertical 3 over 3 signal. It seems to be operating as the DZ-1075M ( (momentary). The package and instructions say DZ-1075. Am I doing something wrong? or has anyone have received products that were mismarked? Thank you.
