Operation Manual of Water Leakage Detector
AD-AS-1BM
First of all, thank you very much for purchasing the Water Leakage Detector AD-AS-1BM.
When using, please make confirmation according to the following items before carrying out various operations.
Using Method
■Connections with the power source, sensor and non-voltage contact output, and setting of the detection precision.
①
Power source
Please connect the AC100V~240V (50/60Hz) to the power source terminal wire securely according to the figure below.
(Note) Do not connect the power source to the nearby terminal by mistake, otherwise, it may lead to device malfunction or fire.
①
Water leakage sensor
Please connect the water leakage sensor, which is installed with the break detection terminal (ZT-2)
manufactured by our company, to the “SEN” terminal securely.
When the break detection terminal is not installed, it will stay at the break detected status.
①
Non-voltage contact output
When water leakage or break is detected, alarm will be delivered from the corresponding non-voltage contacts respectively, please make
connection with the relevant exterior systems etc.
NO: relay contact during detection Off
NC: relay contact during detection On
BREAK: Break 1a contact
LEAK: Water leakage 1c contact
①
Setting of the detection precision
The detection precision 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. The default setting when dispatched from the factory is M.
H: high precision
･････････
14KΩ±30%
M: standard precision
･･････
10KΩ±30% factory setting
L: low precision
･･････････
5KΩ±30%
■ Operation confirmation
The indicator LED will light up when the power source 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 non-voltage contact
output
will beactivated.
In addition, the leakage status detected by the sensor can be confirmed by dripping running water into the sensor.
Afterwards, the alarm can be reset by wiping the sensor with a dry cloth.
Installation Method and Handling Precautions
･
Use the detector in an environment with a temperature range between 0 and 50˚C (no icing) and a humidity range between 35 to 85%
(no condensation).
･
Do not use the detector in any location close to sources of vibration and harmful gas, and strong electromagnetic inductive power sources.
･
Avoid using the socket lead as the power source as far as possible, and use fixed wire to connect power source.
･
Select and use different fixators to fix the sensor according to the installation locations and environment.
･
The structure of sensor is not easily affected by the electromagnetic induction, in case that you worry about electromagnetic interference,
please consult us.
･
Be sure to make operation confirmation after the installation is completed.
･
When the housing and the case body is found dirty, please use soft cloths such as the gauze with small amount of neutral detergent diluted
by water to wipe gently.
