- I am new to this group and hope this is an appropriate question. I acquired an HDX-555 from a ham's widow and have had a problem with the time delay relays that control the motor drive. I wish to rep

- My Tri-Ex LM354-HDSP has a delay circuit for the up side and one for the downside. As the time is set by a fixed resistor, I'm not sure what the intended delay is, but I'd estimate it to be around tw

- Thanks, Doug. I will set them both the same and for about 2 seconds and see if that works. My tower is at our country place, which we visit on week-ends so will check it out then. This problem follow

- Ed: The other thing to check is the cut-off switches. The typical wiring calls for the cut-off switch to be normally closed; when it is contacted by the tower, it opens and shuts off the power to the

- The purpose of the delays are to make sure the motor comes to a complete stop before trying to reverse, because the motor isn't instant reversing. Normal settings are about 5 seconds. The old Tri-Ex

- Ed: I would set them for much longer than 2 seconds. I believe the purpose is to be sure the motor lifting the tower coasts to a complete stop and the tower comes to a halt before you reverse it. Don

- Note, the delay is a safety measure to prevent the tower from "running away." A single phase motor will continue to run in the current direction it any time power is applied. Because of this, it is
