The only thing that will trip the starter, is the load of the motor. Check the motor leads to make sure you have not crossed them over coming from the motor junction box. If the motor current is normal nameplate full load amps when run across the line then reduce the timing of the timer on the switch over from star to delta.
In manual star delta starter, the change over from star to delta does not happen automatically. The operator or user puts on the starter, and after few seconds he pushes a lever or handle to change over to Delta. In automatic method, change over happens from star to delta using an automatic preset timer.

Types of starters: 1. Direct on line starter 2. Autotransformer starter 3. Star Delta starter 4. Resistance starter 5. Fully automatic star delta starter 6. Series reactor starter
There is many type of starter on three phase circuit but the most common are 1: D.O.L (Direct on line). 2: Manual Star Delta Starter. 3: Automatic Star Delta Starter.
No difference. Y is used as a symbol to indicate the star connection.
DOL, Star Delta, Soft starter, VFD

Check the star - delta wiring. It does not seem to be correctly wired.
I assume a 3 phase, AC induction motor. A star delta starter or a soft starter can be used. A soft starter is better compared to a star delta starter, but it is more expensive.
Nope .. Never heard of it .
The use of a star delta starter is for motor control only and not resistive heating loads. This type of starter is used to dampen the inrush current by using a lower voltage to start the motor.
If a motor is connected in a star configuration it will operate at a slower speed. This is the working process that a star delta starter operates on. At first through the starter the motor starts in the star connection. When the motor gets up to its highest speed in that connection it times a timer out , the star starter drops out and the delta starter pulls in and then connects the motor in the delta connection. This allows more voltage to be applied to the motor and it then speeds up to its nameplate rated RPM.
