CONFIGURATION SYSTEM
The Series I3 of isolated signal converters provide a fast and easy
configuration system, based on function codes.
‘CONFIGURATION DIGITS’
The instrument provides two numerical leds, to inform about the actual
state of the instrument, active input signal range, and error codes (see
section 15).
CONFIGURATION KEYPAD
The configuration keypad is located inside the instrument, behind the
removable front cover. To access the configuration keypad, remove
the input signal terminal, and open the front cover (see section 9). The

light down from top to bottom, and the instrument returns to
‘ normal mode ’ of operation.
‘ROLLBACK’ FUNCTION
If there is no interaction from the operator for 60 seconds, the instrument
exits the ‘ configuration mode ’ and returns to ‘ normal mode ’ of operation,
