Main Functions
Liquid Leakage Monitoring
Detection of Changes in Liquid Leakage
• Extent of Leakage
Any spreading of leakage from the current location is detected.
• Detection of Second Leakage location
Leakage at a separate location from the current leakage location is
detected.
Up to 600 m of Cable for a Single Sensor
A maximum length of 600 m is possible by combining Sensing Cables
with other cables. When Cables are connected, the length of Sensing
Cable is automatically displayed. The length of the F03-21UP-JC
Junction Cables is not included in the displayed cable length.
The distance displayed for each Area Separator is equivalent to 10 m
of Sensing Cable.
A Selection of Detection Sensitivities
Two levels of leakage detection can be selected.
Disconnection Detection
Cable disconnections from the Controller to the Terminator are
detected.
Input
Shift Function
This function changes the 0-m position for the Sensing Cable. When
there is a distance between the Controller and the location where the
leakage is detected, the display can be made easier to understand by
changing any distance to 0 m.
Compensation Function
This function changes the length of the Sensing Cable to any value.
When there is a discrepancy between the actual length and the
measured length, this value can be revised to any value for
compensation.
Output
Relay Output
Can be set to normally open or normally closed.
Output Reset
Any of three patterns can be selected for the output reset method.
RS-485 Communications
Either CompoWay/F or Modbus can be selected as the
communications protocol.
Linear Output
4 to 20-mA output can be selected.
Other
Display Language
Either English or Japanese can be selected.
Event Log
Timestamps for up to 20 events and leakage occurrences can be
retained.
Output Testing
Testing can be conducted without connecting the Sensing Cable.
Key Protection
Unintended setting changes can be prevented.
Backlight ON Time
The backlight can be set to always remain ON or to turn OFF after a
specified time.
Area Settings
Laek positions in meters can be divided into up to 20 areas.
F03-20UP-AS Area Separators can be used to enable accurately
identifying the detection area in which a leak has occurred even when
the leak occurs near an area boundary.
