Jay, It waits 50 seconds to even start to try to shift the frequency. I don’t know how long it takes to get up to get to 64 HZ. I heard somebody say that they thought that the 50 second delay should be adjustable, but I could not find a way to adjust it. I have not had a chance to talk to Schneider tech-support about it since then.
I had a problem with this on a job, by the time the Schneider would change its frequency, the voltage would be way over an acceptable voltage. I had to adjust the voltage setpoint down in order to try to shorten the delay. That was not really a good workaround because how quickly the voltage rises depends on the charge rate. I know that all of the delays and ramp up speeds and ramp down speeds are fully user adjustable on outback equipment, I hope that Schneider has added this adjustability by now... but last time I checked, I don’t think you could.
