Questions and answers
Добрый день! Подскажите пожалуйста , куда подключить контакты 501 , 502,503 на микроконтроллере АВР CHINT NZ7 к генератору 100 кВт CTG для его запуска и останова двигателя
To connect contacts 501, 502, and 503 on the CHINT NZ7 Series microcontroller to a 100 kW CTG generator for starting and stopping the engine:
- Contact 501: Connect this terminal to the generator's start input. It sends the start signal when generator mode is active.
- Contact 502: Connect this as the common terminal (COM) in the control circuit.
- Contact 503: Connect this terminal to the generator's stop input. It sends the stop signal to shut down the generator.
Ensure these connections match the generator’s control signal requirements and follow safety procedures during installation.
