Drawing 6 Control Output Contact
Alarm contacts
COM-NO: Closed when a break is detected.
* Regarding contact operation
Changing operational setting switches shifts Contact a to Contact b. (Refer to Drawing 3.)
Water Leakage Location Data Output Connection
5-5-1 Connection
The AD-AS-1LDMA has a function that outputs the water leakage location by DC electrical current. (Option)
*
Use an analog input device with an input resistance of 500 Ω or lower.
Drawing 7 Water Leakage Location Data Output Connection
(Output specifications)
Normal sensor output current = 4 (mA)
Sensor output current in the case of sensor break detection = 20 (mA)
Output current in the case of water leakage detection = 6 + 0.03 x water leakage location indication (mA)
