Operation Manual of High Sensitivity Water Leakage Detector
AD-AS-1C-SR
First of all, thank you very much for purchasing the Water Leakage Detector AD-AS-1C-SR.
When using, please make confirmation according to the following items before carrying out various operations. .
Operation Method
■Setting for break detection function, connections with the power sensor and non-voltage contact output, and setting of the detection sensitivity
①
Break detection function setting
The break detection function is possible to be set use or nonuse
Factory setting is “Activated” for use.
※
For safety, please set before the detector installation and wiring.
Setting methodthe small screwdriver such as the precision screwdriver is inserted into the horizontal side before (
①
)1C-SR housing, to open the housing.
・
Small changeover switches are set near the break detection function on the lower left of the inner base board and near the printed words.
Use instruments with sharp top like precision screwdrivers to operate the switch according to the following requirements.
◆
When the break detection functions is activate: “Activated” side (the switch is at “1” …
the factory setting
◆
When
the break detection functions is
not activated:
“Not activated” side (the switch is at “ON”)
※
When the break detection function is activated, be sure to install the break detection terminal of the same package at the top of the
sensor (Product name: ZT-SR).
When the break detection function is not used, installation is needless to be carried out.
②
Power
Be sure to connect any of AC100V or AC200V to the insulation transformer.
When connecting AC100V, connect it securely between 0V(E)-100V terminals,
When connect AC200V, connect it securely between 0V(E)-200V terminals.
To prevent the static electricity, be sure to connect the terminal of 0V(E) with the earth wire.
③
Water leakage sensor
Please connect the water leakage sensor
securely to the “SEN” terminal with wires.
When the break detection function is activated,please make sure that the break detection terminal
（

）
is installed at the top.
④
Non-voltage contact output
It is output as the fault safety device.
When the detector is normal without alarm, the non-voltage contacts Contact 1a and Contact 1b are activated.
In the case of the detection of water leakage, break and power-off, Non-voltage contacts output Contact 1a and Contact 1c are output as
below.Please operate it with care.
NO
：
during the detection of the leakage and break and power-off, the relay contact is Open”
NC
：
during the detection of leakage and break and power-off, the relay contact is “Closed”

Detection sensitivity setting
The detection sensitivity can be set with respect to the installation environment, sensor length and the water quality detected accordingly.
Use the slide switch to select positions L, M and H for setting.

3.3MΩ±20%.
■ Operation confirmation
The indicator LED will light up when the power is switched on.
The water leakage status can be simulated via short circuit among the “SEN” terminals.
At this moment, the indicator LED will light up, indicating that the water leakage has been detected, meanwhile, the no-voltage contact output will be activated.
When the setting of the break detection function is activated, for example, if the water leakage sensor is removed, it will be at the status of break, the indicator
LED flashes fast intermittently, in the same status as the water leakage , the non-voltage contact output changes.
In addition, the water leakage status detected by the sensor can be confirmed by dripping the running water into the sensor.
Afterwards, the alarm can be reset by wiping the sensor with a dry cloth.
Use the detector in a working environment with a temperature range between -10~50˚C (no icing) and a humidity range between 35~85% (no condensation).
Avoid using the detector near sources close to sources of vibration and harmful gas, and strong electromagnetic induction.
For connection to the power supply, avoid using receptacles; use fixed wiring connection.
Select and use different fixators to fix the sensor according to the installation locations and environment.
