I think I have determined there is a basic electrical incompatibility between Atlas O 200 snap relays and DZ-1000 motors. I want to pass this through the forum to see if anyone has had this experience or if I am all wet. Any comments would be appreciated.
I am using the relays to power DZ-1011R detectors (tape over the IR detector) to indicate turnout position. Like the DZ1000 the center post on the 200 is connected to power. However the L and R posts of the DZ1000 go to common (connected to toggle switches on my control board) while it appears the L and R posts of the 200 go to power (internally - inside the relay). I connected the L/R wires between the DZ1000 and 200 so that throwing the DZ1000 would activate the relay and change the light indication on the DZ1011R. My DZ1000 switch machines would work most of the time but sometimes the motor (control arm on top of the machine ) would not fully switch positions.
While not a hard short I think the 200 relays were affecting the performance of the DZ1000 motors. I removed them from the circuit under the train table and found the switch motors to be a lot more 'lively' now. Time will tell if this is the issue.
