First of all, thank you very much for purchasing the Water Leakage Detector AD-AS-10DRM.
Before using, read this operation manual carefully to ensure correct operation. Keep this manual in a convenient place for
quick reference.
1.Installation and Handling Precautions
1-1. Installation
1)Remove CPU unit and 5-circuit expansion unit from the body case. (Use M3 screw)
In winter, pay special attention to static electricity and install by holding board edge.
2) Drill installation hole and connecting hole on the body case, do not leave cutting power, etc.
3) After the body case is installed in the setting place, install various units removed in 1).
4) Install the terminal block wires and connectors on the CPU unit and 5-circuit expansion unit.
1-2 Handling Precautions
1) Use the detector in an environment with a temperature range between -10˚C and 50˚C, and a humidity range
between 35%. and 85%.
2)Do not use the detector in any location close to sources of vibration and harmful gas, and strong electromagnetic
inductive power sources, which may lead to malfunction and failure.
3) Avoid using the socket lead as the power source as far as possible, and use fixed wire to connect power source.
4) After installation, be sure to conduct tests in conformance with the operation check items described in Chapter 3.
2. External Connection
To form CPU unit AD-AS-CPU and 5-circuit expansion unit AD-AS-UNIT, set the terminal block as shown in Drawing 1.
Drawing 1 Layout Drawing for Terminal Block
2-1 Power Connection
Before connection, check that the power supply voltage is within the range of use, then connect it securely to the
terminal block.
＊Inputting a power voltage outside the range of use may cause malfunctions and failure of the detector, so care should
be taken.

2-2 Water Leakage Sensor Connection (Refer to Attached Drawing 3 and Attached Drawing 4)
Connect the water leakage sensor to the “S1”-“S10” of the sensor connection terminal block. The sensor has no polarity.
Example: For S1, connect the water leakage sensor to A-6 and B6.
*Be sure to install break detection terminal on water leakage sensor.
If it is the point sensor, use break detection terminal built-in product (AD-PA-R).
(Precautions)
◇ When sensor is not connected, set the DIP switch at the position “ON”. When not set “ON”, break alarm will be
output. (Note) DIP switch dispatched by the factory has been set at the position “1”.
◇ When conducting wire change, etc., conduct it under the condition that the detector power source has been cut off.
◇ A-1 and B-1.are not used Do not connect water leakage sensor.

*Contact operation
Setting SW2 on CPU unit can enable the alarm hold and the fail-safe function to be effective.
* If the fail-safe function is effective, the contact will be operated reversely.
For details, refer to Attached Drawing 6 and the Operation Chart of Chapter 4.
*Abnormal contact
Setting SW2 on CPU unit, the operation can be changed as activated only when the break and
recovery occur.
For details, refer to Attached Drawing 6.

5. Adjustment of Water Leakage Detection Precision
Drawing 9 Resistance/ Detection Sensitivity Indication
5-1 Adjustment Method (Refer to Attached Drawing 3, Attached Drawing 4, Attached Drawing 5 and Attached Drawing 6)
1) Rotate circuit selection switch to select the circuit required to be adjusted.
2) Set the 1 of SW2 on the CPU unit ON to indicate detection sensitivity.
(Drawing 9 shows that the target detection precision of Circuit 1 has been set 5.0ｋΩ.)
3）Rotate the precision adjustment VR of the required circuit, observe the precision indication while adjusting the value
required to be set.
Clockwise rotation indicates that the precision is higher, and counterclockwise rotation indicates that the precision is
lower.
The detection precision can be adjusted within the scope 2.0ｋΩ～9.0ｋΩ±10％ by the interval 0.5ｋΩ.
4) If the precision adjustment is completed, set the 1 of SW2 at CPU unit to be OFF.
The detector of the company has been adjusted to be the standard precision (about 5ｋΩ) according to the
characteristic of the water leakage sensor (manufactured by our company) when dispatched from the factory.
When the detection precision is required to be changed, contact with our company for confirmation.
6. Buzzer Setting
6-1 Buzzer Volume Setting
Perform volume adjustment through the volume adjustment VR of the indicator unit.
When rotating clockwise, the volume is increased and when rotating counterclockwise, the volume is decreased.
When dispatched from the factory, the volume has been set as the maximum.
6-2 Buzzer Stop Setting
1) Applicable to the occasion when alarming, buzzer sounding is required not to be activated temporarily
When alarming is given put, press the buzzer stop switch, the buzzer stops, indicator LED lights up and the buzzer
stops temporarily.
However, if the same circuit or other circuits alarms again, the buzzer stops, the indicator LED lights out and the
buzzer sounds again.
When the alarms from all the circuits recover, the indicator LED for buzzer stops lights out.
(Refer to Operation Chart in Chapter 4)
2) When the buzzer sounding is required not to be activated often
Set 8 of SW2 of the CPU to be ON.(Refer to Attached Drawing 5)
When the indicator LED for buzzer stop lights up, the buzzer sounding is set to be not activated..

7. Maintenance and Periodic Inspection
◇ When inspecting the facilities, conduct inspections in conformance with the operation check items described in
Chapter 3.
（Note）During inspection of the detector, the control output contacts are functioning, so if the control output
contacts are used, adopt the measures such as underlay wiring in order not to affect other devices.
◇ Be careful to prevent oil-based substances, such as wax, from adhering to the sensor; this may repel water and
interfere with correct detector operation.
◇ If the sensor is tainted with water absorbing substances, electrically conductive dirty water, etc., replace it with a
new one.
