What are the parameters on which the timing of star delta starter depends?

The timing should allow the motor to get up to full RPM in the star configuration before switching to delta configuration. Depending on the motor size and inertia loading it will be from 5 to 10 seconds.

What is a manual star-delta starter?
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.
What device may be wired into the starting circuit of a motor to improve the starting torque?
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.
Why timer can be used in star delta starter?
delay timer
How much KW range can be use star-delta starter?
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.
What is the use of the rheostat in a star and delta starter?
There is a small potentiometer fitted to the delta timer. This is the time delay between the start button being pressed and the changeover to delta operation. If the starter trips on overload when changeover occurs you need to increase the time delay See related links

What is the difference between a Y - delta starter and a star - delta starter?
No difference. Y is used as a symbol to indicate the star connection.
What are several types of starters?
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
What is a manual star-delta starter?

What are the different types of starter?

What is a Manual starter?
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.
Why is the automatic star to delta starter tripping?
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.

the starter is on the driver side. It right by the oil pan

disconnect the battery, then the wires from the starter. Then remove the bolts holding the starter to the engine.
