5 2.Installation and Handling Precautions 2- Installation The Water Leakage Position Detector (AD-AS-LM-A) shall be securely installed in a strong housing, on the wall, etc. inside a building.) Be sure to follow the instructions below when installing this product. ) Avoid installing the detector in any location subject to high temperature and high humidity, excessively dusty environments and corrosive gas environments. 2)Install the detector in a location that is free from vibration, away from sources of interference such as power switches, and convenient for quick maintenance and regular inspection. 3)Install the inductive sensor using the suitable fixator, according to installation location and environment. 4) onsult with us in case the inductive sensor is used in places easy to be affected by electromagnetic induction. 5) Do not insert foreign matters, including screw-drivers into gaps in the detector. 6) Do not use the sensor as electric wire. 7) Never use inductive sensors other than our product AD-LS Sensor. This will cause serious errors in the location detection function. So pls make sure not to use or use together with any sensor other than AD-LS sensor. 2-2 Handling Precautions )Use the detector in an environment with a temperature range between -0 and 50 and a humidity range between 35% to 5%. 2)Do not use the detector in any location close to sources of vibration and harmful gas, and strong electromagnetic inductive power sources. 3)After installation, be sure to apply the insulating sheet to the terminal block, and cover the surface cover plate, meanwhile confirm the operation. 3. Maintenance and Periodic Inspection 2When inspecting the facilities, conduct inspections in conformance with the operation check items described in hapter 6. Note)During inspection of the detector, the control put contacts are functioning, so if the control put contacts are used, disconnect the wiring or connect temporary wiring in order not to affect other devices. 2If the surface and inside of the sensor is adherent with water repellant substances like oil, normal operation is possible to be interfered. Please pay attention. 2If the sensor is tainted with dirty water, please replace it in time. -2-

13 3 Regarding the operation when the alarm hold setting is activated When the alarm hold setting is activated, the alarm status is held until the cancel switch is pressed. lectric power failure or power-off returns the contact operation status to that when the power source is shut off. When alarm holding is not set, refer to Drawing -5 and peration hart. Regarding the Alarm Indicator LD The Alarm Indicator LD does not maintain alarm status. The Alarm Indicator LD goes when the system detects recovery from water leakage status and break status. If the Alarm Indicator LD continues to flash even after the water leakage sensor is wiped with rags etc., this indicates that water leakage may occur at multiple locations. After completely drying the water leakage sensor at the location that the indicator displays, press the alarm cancel switch. * If drying is insufficient, deviation may occur between the water leakage location displayed after the alarm cancel switch is pressed and the actual water leakage location.. Indication of Detector Number Related settings are necessary to be carried if it is expected to indicate number on the indicator, in the case of multiple indicators are used together. Turn the Detector Number Setting Switch and select a number that you want to indicate. (Refer to Attached Drawing 9) The detector number is indicated on the leftmost 7-segment LD.(~9,A,B,,D,,F) *The factory setting is 0 (no indication).

Detection Sensitivity Setting hanging operational setting switches changes the detection sensitivity level. (Refer to Drawing 20.) *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.
