Is it a rotary Transwave or a static? They are fundamentally the same but the static has a separate transformer, and the rotary has a motor especially wound to use as a transformer.
Basic principle is mains is transformed to 415v and this is presented across L1 & L2 of the output. L3 is derived from L1 but via a bank of capacitors. A voltage sensitive relay monitors the voltage on L3, and when it is high enough (as the motor has started to spin up to speed) the capacity of the capacitor bank is reduced. (ie there is a starting 'chunk' and a running 'chunk' of capacitors, and the starting one is dropped out of circuit by the relay when it pulls in.
In the case of the rotary converter the motor is inbuilt and once running the third phase is generated adequately to run motors from very small up to about the size of the inbuilt one.
In the case of static converters, the motor is the one you are connecting, and unless you tweak the amount of capacitance in circuit to suit your motor you will run the risk of burning out small ones and not being able to start bigger ones. Hence they usually have a rotary switch on the front to set the capacitance.
Transwave (Power Capacitors) are a very helpful approachable company, why not talk to them about the problem with your one.
If you have looked at the basic layout
you should be fine.
I drew a DIAGRAM of mine, not sure how clear it is
as I am s***e at diagrams and I drew it some time after making
one and hadn't used a diagram.
when I asked if you had a diagram I wasn't asking about one
from the makers I was wondering if you could draw, or had drawn
one of how it is.
Here's a copy of the diagram I came up with for mine.
Its a rotary converter - currently running on a 15hp idler.
No transformer is needed as a delta star change over circuit increases the voltage within the motor. The motor therefore must be a multi voltage motor (230V and 415V) - however no transformer is needed.
I've got a 500uF starting cap and only an 8uF run cap as its very balanced.
The control for the contactors has changed a bit - the whole thing is automatic now - the change over and start cap cut out is done by a timer. It also now has a thermal overload relay and an RCD and MCB on the output.

Oh now, you have opened a tin of worms. It does have a transformer, 3 caps, 1 motor (3wires) a voltage relay and 2 Contactors, one with a thermal cut out.
