8. Indication of Detector number
The Detector number, which is used when communicating to the host system, is set by use of the rotary switch below.
Setable the range of the Detector number is between 1 and 15 by use of the rotary switch.
* The factory setting is 0 (no indication).
When setting the 16 to 127, set by operating
“Alarm Cancel Switch” and “Buzzer Stop Switch”.
See the accompanying sheet for details.
The Detector number is indicated on the upper left of the LCD.

9. Detection Sensitivity Setting
Changing operational setting switches changes the detection sensitivity level.
* The water leakage sensor detects water leakage even it is caused by only a small amount of water
(condensation, for example). Therefore, if the sensor is installed in a location subject to high temperature
and high humidity, set the sensitivity level lower.
* In the case in which it is necessary to detect fluid with high electrical resistance, such as pure water, in an
environment where the temperature and humidity are stable, such as a clean room, it is recommended to
set the sensitivity level high.
10. Buzzer Setting
Changing operational setting switches changes not to sound the buzzer.
It is possible to change the above setting from the host system by the Modbus communication.
