TM II, York turbo modulator.......?

[Legacy80]

any chance of having some service manuals for a York TM II / turbo modulator? motor is stalling/hesitating, DC bus voltage is over 500.....

ps. I didn't think any of these were still in existance....
Thanks!

correction... output voltage is over 500...

checked the literature that i have and can not finding anything about a fault for the output voltage of the drive being over 500 volts. What was the line side voltage feeding the drive and the DC bus voltage?

A co-worker of mine was working on it so i don't have all the info. The chiller itself never faulted. It would just run full speed and sound like it was almost single phasing (best way i can describe) hue found some info and narrowed it down to the trigger board. Thanks for the reply.

He was asking me what the dc voltage should be..... But I couldn't find it in any of my literature.

if my memory serves me right i think it is usally around 600vdc under 450 and over 745 vdc i think is a problem.
