Home Forums General Discussion Technical Questions TK TAC 20-03 controller

Hi all. New to your forums. Need some help. I am a fix-it-up guy at our church. Our TK elevator recently stopped working. I can get the motor starter to flash a message by cycling the power. It says something like, 'line in low, motor stopped, control voltage low.' And then I can test the terminal block on the side of the starter and on the line that says "control voltage" I get nothing. So I trace the wire back to a connector on the main card (IOA.) From here I am not able to troubleshoot the card itself. So I was wondering if anyone has any suggestions as to what to look for on the card or upstream of it that would cause the control voltage to stop to the motor starter? Fuses (checked the 4 I found on the card)? Are there safety switches in-line inside the car or hoistway before the starter control voltage? Relays on the card? ............ thanks. J

fix it up guy- I think you will find that your request for advice will go UN-answered. We realize elevator companies charge a lot and sympathize. However that being said, they are not to be worked on by someone not trained in elevator repair. Please do yourself and your Church a favor and call an elevator company. When someone can get hurt, it pays to call professionals. Think of it like this, would you get on an airplane that has been worked on by fix it up guy.

The best advice I can give you is this: The elevator says Thyssen-Krupp on it. Call Thyssen-Krupp.

J,
JohnJay & Rac66 are giving you sound advice. Today's elevator equipment is very complex. Elevator Professionals spend years working in the field and attending classes in order to complete there training.

Checking fuses and recycling the main line is one thing. But as you have stated you don't know what is "UPSTREAM". We wouldn't want you to do something that may put you in harms way. But more importantly we don't want your actions to put someone else in harms way.

We, as professionals who have years of practical experience, education and safety training are fully aware of the danger and hazards our industry.

It's obvious you have skills in related areas. I wouldn't recommend you apply your skills to this area. Taking this sort of chance to save what is not a lot of money doesn't justify risking others health or life.
