5-5-2 Abnormal Water Leakage Location Data Output
In the case of abnormal water leakage location data output, an indication of “E01” is added on the 3-digit,
7-segment LED. (Refer to Drawing 11.)
This may result from the causes described below. Check the facilities.
Detector: Wiring connection among external analog input devices is broken or the input resistance for external analog
input devices is more than 500Ω.
