ACA Banshee 115 W/ Baldor 15HP

[jbmole]

I apologize in advance if this question has been answered already, but I have a Banshee 115 at a fire station with an ACA controller and someone has removed the voltage control relay and replaced it with a "standard" open frame relay. As such, the start caps never engage and the siren takes far too long to spin up. The in-rush on start-up is around 240 amps, which is not horrible, but it takes the better part of 15 seconds before the current stabilizes at 65 amps. Furthermore, the contactor never closes, especially on start-up as it should. The million-dollar question is, what is the correct part that I should have there, more specifically what part number? I really appreciate everyone's time and I hope I am not repeating a question already asked! Thanks for any advice!

You would not happen to have any photos of the controls, would you? If you could post them that may help.

I have uploaded a picture and I hope it helps. This controller has had so many hands in it over the years and so many changes. I have changed all the capacitors and I have purchased a supco APR5 but it is only a 3 wire potential relay and the original one I believe was in the controller BEFORE the simple relay that is there now was a 4 wire relay.

Where are you located? Best thing for that situation would be to go through and replace all the capacitors and rewire the controls. Someone who had no idea what they were doing went through it.
