LED1 to LED8 are user-configurable, whose color can be selected from green, yellow and red by
MIMIC editor. Each is driven via a logic gate which can be programmed by PLC function.
The TRIP, ALARM and an operated LED if latching operation is selected, must be reset by user,
either by pressing the RESET key, by energising a binary input which has been programmed for
'Remote Reset' operation, or by a communications command. Other LEDs operate as long as a
signal is present. The RESET key is ineffective for these LEDs.
The VIEW key starts the LCD indication and switches between windows. The RESET key
clears the LCD indication and turns off the LCD backlight.
The operation keys are used to display the record, status and setting data on the LCD, input the
settings or change the settings.
The RS232C connector is a 9-way D-type connector for serial RS232C connection. This
connector is used for connection with a local personal computer.
