• LED ERR (red) to indicate
−
a sensor fault (flashes red)
− the simulation mode (only when using FDT flashes red)− a
device fault (steady red)
• PWR LED (green), to indicate the presence of the supply voltage
• LED OUT 1 (yellow), to indicate that relay 1 is active
• LED OUT 2 (yellow), to indicate that relay 2 is active
• serial RS 232 interface to connect to a PC for parameterisation and
diagnosis of the Strain Gauge Converter using FDT.
• a display for measured value and error message display and for
