if my memory serves me right i think it is usally around 600vdc under 450 and over 745 vdc i think is a problem.
He was asking me what the dc voltage should be..... But I couldn't find it in any of my literature.
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.
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?
correction... output voltage is over 500...
TM II, York turbo modulator.......? 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!
