The Be42 (or Be42N) is 3-phase A.T.S. controllers & Generator monitoring systems. Its programming runs quickly, and all parameters, alarms and operating functions are indicated by means of a high-luminosity display capable of operating in a temperature range between -30°C and +70°C. The Be42 interfaces with resistive sensors up to 2000 Ohm. Measurements including Vac, Aac, Vdc, Hz, hour count, R.p.m., Oil Pressure, Engine Temperature, Battery Vdc (Engine) and Fuel Level. A software for remote monitoring and control software program is also provided. The Be42 provides RS485 MODBUS. Be42 complies with NFPA-110 / NFPA-99 specifications.
