6. Water Calibration: A value (in μA) that is equal to sensor output when floating properly in
clean water. If the measured signal is more than Water Calibration - Oil Delta +
Hysteresis, then the status is WATER.
Note: When the Calibrate button is pressed (on this line while in the Change mode), a
measuring cycle is performed, and the sensor signal is taken as Water Calibration. This
means that the sensor must be in clean water when doing this.
7. Current Season, Winter Offset: Either Summer or Winter. In winter, the parameter
Winter Offset is subtracted from Water Calibration for compensating the influence of water
icing.
8. AutoCleaner Installed: Future feature. Relevant for a ID-227 sensor connected as sensor
number 1. If Yes is selected, the automatic sensor cleaning will be enabled.
9. Alarm at Air: If Yes is selected, Air status will be treated as an Alarm condition. Select
Yes for ID-221 or ID-225 or ID-227. For ID-223 it depends on the application.
10. Sample Interval: Relevant for firmware versions before 4.1. Determines how often the
system will take a signal sample from the sensor for validating / updating the status. This is
important for battery operated systems. The interval can be between 30 seconds and 15
minutes, or it can be sampling Continuously.
11. Delay Time (Filter): Relevant for firmware versions before 4.1. A delay window between 1
and 30 seconds on the reading from the sensor. This is important if the sensor is installed
in a non-stable liquid environment. Any alarm will have to be present enough readings
within the delay window to take effect as a valid status. See also Alarm Reading
Percentage Threshold.
12. Warm Up Time: Relevant for firmware versions before 4.1. A period letting the sensor
reach a stabilized output signal after it is turned on. The sampling is done after this period
has ended. This parameter should be correlated with the level of liquid instability in which
the sensor floats. This period can be set between 0.5 second and 15 seconds.
Save to SLC button: Writes the updated parameters to the SLC-220 unit, and updates the View
Parameters column on the left.
Load from SLC button: Reads the existing parameters from the SLC-220 unit for viewing and
changing if necessary.
Save to PC button: Writes the updated parameters to the PC as a xml file.
Load from PC button: Reads parameters from a xml file in the PC for viewing and changing if
necessary, and for saving to the SLC-220 if necessary.
Exit (Back) button: Return to the Main Sensors View screen.
