3. SETTING INPUT TYPE
Set input type according to the signal range of an input device to connect.
Choose an input type so that the signal range of the device is the same as the measuring range of the input type or within
the setting range.
e.g. Input signal 0 – 16 mA AC
→
Within setting range of input type ‘20MA’, 0 – 20 mA
Choose ‘20MA’.

CONFIGURATION EXAMPLES
Configurable
• Input signal 0 – 16 mA AC, input type ‘20MA’ (measuring range 0 – 20 mA)
Not configurable
• Input signal 0 – 22 mA AC, input type ‘20MA’ (measuring range 0 – 20 mA)
IMPORTANT
• Setting beyond the setting range of an input type is not available.
• Even small input signal can be set within the setting range of an input type, however the accuracy will be worse.
Choose appropriate input type and code.
• The input and display scaling values, bargraph lower and upper limits, analog outputs 0% and 100% are returned to the
previously set values per input type (or default values when the input type is selected for the first time) when the input
type has been changed. All alarm setpoints of the current bank No. are disabled (reset to ‘------’ status). Also other
alarm parameters (trip action, deadband, OFF delay time and coil at alarm) except for the ones concerning the P status
are reset to the default values. It is recommended to record the current settings as necessary.
