For Generac GP8000E GP7500E GP6500E Electric Gas Generator

The switch symbols are ○ (O gear, Off/Off), Ⅰ (Middle gear), Ⅱ (Three horizontal lines, On/Run gear), combined with the "Automatic Reset" feature:
O gear (hold position): The switch defaults to a stationary position, disconnecting the main circuit.
I gear (automatic reset position): After being turned, it automatically bounces back to O gear, which is a momentary trigger position (such as the "start" signal).
Second gear (hold position): After being turned, it remains in this gear for continuous operation (if the generator is working normally).

Proficient in referring to the on-off rules of each gear:
O gear (Off):
Group 1: Connect COM1 (pin 1) to NC1 (pin 2), disconnect NO1 (pin 3);
Group 2: Connect COM2 (pin 4) to NC2 (pin 5), disconnect NO2 (pin 6);
→ Function: Disconnect the main circuit and connect to the "shutdown monitoring" or "standby circuit".
Level I (automatic reset, momentary action):
When shifted to gear I, the spring force causes the switch to automatically bounce back to gear O, instantly connecting:
Group 1: Connect COM1 (pin 1) to NO1 (pin 3);
Group 2: COM2 (foot 4) and NO2 (foot 6);
→ Function: Transient trigger signal (such as the "start" command of the generator, which automatically shuts down when released, and needs to be coordinated with a self-locking circuit to maintain operation).
Level II (hold, continuous operation):
When shifted to gear II, the switch remains in that position and continues to turn on:
Group 1: Connect COM1 (pin 1) to NO1 (pin 3);
Group 2: COM2 (foot 4) and NO2 (foot 6);
→ Function: The main circuit provides continuous power supply (such as the "normal operation" gear of the generator).
