User Manual
Sensor
The actual sensor configuration is based on the selected channel type. The
following table lists settings available for each channel type.


Sensitivity : specifies the sensor sensitivity such as volt or amp ratio.

Zero Level : specifies the voltage or current value which equals zero on the
measurement scale.

Offset : sets the temperature offset for the sensor.

Sensor OK Settings (Min & Max): these two properties are used to define
an acceptable range for values returned by the sensor. Any reading that falls
out of these limits will trigger a circuit fault condition.

It is strongly recommended to configure Sensor OK settings within
±23 V and not to disable Sensor OK.

Sensor Fail Value: this applies to Temperature and Other channel types.
This is the value that the system will present upon the detection of sensor
failure. The sensor fail value can be either
Scale Min , Scale Max or Measured .

When a sensor fail has been detected, the measured value is not
reliable but may give an indication of what type of error it could be
(out of range, short circuit, open circuit, etc.).
