8.3.2 Input Indication Range
The input value is displayed within the following range:[Indication value at input 0% – (Indication value at input 100% – Indication value at input 0%)
x 10%]
to[Indication value at input 100% + (Indication value at input 100% – Indication value at input 0%)
x 10%]For a value lower than (and including) -2000, the minus (-) sign and the input value light up
alternately.
For a value higher than (and including) 10000, the lower 4 digits flash.
(The placement of the decimal point follows the selection.)
When the input value exceeds the indication range:
flashes.
When the input value drops below the indication range:
flashes.
8.3.3 Input Burnout or Disconnection
If thermocouple or RTD input is burnt out, overscale or underscale can be selected.
If overscale is selected, the output is forcibly limited to 110%.
If underscale is selected, the output is forcibly limited to 0%.
If overscale is selected and input is burnt out, the Alarm indicator lights up, andflashes as an input value.
If underscale is selected and input is burnt out, the Alarm indicator lights up, andflashes as an input value.
