NOTE:
The fail sensor alarm is issued if the measured resistance is smaller than one half of the first (lowest)
point of the sensor curve characteristic or is greater than 112,5% of the last (greatest) point of the
sensor curve characteristic.

Tristate inputs
Analog inputs can be used also as binary or tristate, i.e. for contact sensors without or with circuit
check.Thethresholdlevelis750Ω.Incaseoftristate,valueslowerthan10Ωand valuesover2400Ω
are evaluated as sensor failure (short or open circuit).
