Electrical Control System
▪ SYIC-2 integrated control system independently developed by
SANY is adopted to ensure high system integration, accurate
operation, and reliable quality. The control system mainly
includes power system, engine system, master control system,
load moment limiter system, auxiliary system, and safety
monitoring system.
▪ The controller, monitor, and the engine communicates through
CAN Bus.
▪ Monitor: the working parameters and status are shown on the
monitor, such as the engine speed, fuel volume, engine oil
pressure, servo pressure, engine working hours, lifting conditions
and boom angle.
