Area detection function
The area detection function performs judgment by the rate of the oil film present on the
detection area.
Alarm output can be avoided in a case where a trace oil film always floats on the water
surface.
Setting step
Set the area detection setting value to 10
or more (10
to 90
) to activate the area
detection.
Set the detection area (warning, alarm) within the range from 0
to 90
.
Ensure the following: [Detection area (WARNING)
Detection area (ALARM)].
Set the detection area by referring to the value of detection level monitor in the test mode.
(Fig. 2 shows an example of area detection setting step.)
The factory default setting is as follows.
Detection area (WARNING): 0
, Detection area (ALARM): 0
, Area detection: Invalid
If the detection area is set to 0
, it is possible to detect the oil film of trace volume.
For detailed explanation of detection level monitor and detection area setting screen,
refer to “ Detection area setting ” (page 36).
