Sistem Kontrol Hitachi ZX200

Main controller (MC) digunakan untuk mengontrol ope- rasi mesin. Signal kelistrikan dari engine control dial, dan bermacam sensor dan switch, dikirimkan ke MC. Setelah diterima di sirkuit logic-nya dan dip-proses, maka selanjutnya MC mengirim keluar signal pengon- trol ke motor EC, solenoid valve unit, torque control solenoid unit, dan sirkuit pengontrolan yang lain untuk mengatur engine, pompa-pompa, motor dan valve- valve.
