Control of industrial drives such as compressors, pumps and fans
Multi-unit load sharing, synchronous grid connection, and islanded operation
Reliable control in hazardous areas and industrial sites including oil & gas, petrochemical and power plants

Installation & Commissioning Guidelines

ESD Protection: Discharge static electricity before operation; handle PCB by edges only.
Power Supply: Low-voltage version must not exceed 18–40 Vdc; a battery charger is required for battery-powered systems.
Wiring: Use shielded twisted-pair cables for signals, with single-point grounding of shields.
Jumpers: 10 internal jumpers for output type and sensor type configuration (default: MPU).
Commissioning: Enter Configure menu with engine stopped; adjust parameters in Service menu during operation, and save settings to EEPROM.
Communication: Terminate both ends of RS-485 with 100–120 Ω resistors; place RS-422 termination at the farthest receiver.
