Pre-defined operating modes
The green, yellow and red LED and the buzzer can be controlled via three pre-defined operating modes. These three modes can be activated via Modbus register 11. Writing '0' in Modbus register 11 will activate 'normal' mode - green LED on. Writing '1' in Modbus register 11 activates 'warning' mode: yellow LED on. Writing '2' in Modbus register 11 activates 'Alarm' mode - red LED and buzzer on. There is also the possibility to control each LED and the buzzer separately. Consult the mounting instruction for more information.
