(B) is conductive and the auxiliary relay (R 1 ) operates, but the wiring lines (e), (f), (g) do not conduct and the circuit protection timer (T 2 )
And the time setting timer (T 3 ) does not operate either, so it is an auxiliary relay.
(R 3 ) also does not work. Therefore, the water is sent to the water supply pipe (7) with the electromagnetic valve (14) kept closed. Then, the operation of the water pump (8) is stopped and the stop time measuring means (T 1 )
When counts 3 hours, the contact (t 1 ) closes and the auxiliary relay (R 2 ) operates, which causes the contact (r 2 ) to close. However, since the contact (r 1 ) of the wiring line (e) is open, the wiring line (e) (f) (g) does not conduct. Therefore, the auxiliary relay (R 3 ) does not operate, and the solenoid valve (14) remains closed, so that the self-maintaining state is maintained for 3 hours or more and any number of hours.

水を送水させる。Next, when the operation of the water pump (8) is started, the wiring lines (e), (f), (g) become conductive, and the circuit protection timer (T 2 ) and the time setting timer (T 3 ) start counting. And
When the set time of this timer (T 2 ) e.g. 2 seconds has elapsed, the contact (t 2 ) of the wiring line (h) will close and the auxiliary relay (R 2
3 ) operates to open the solenoid valve (14) to send water to the drainage or recovery pipe (10). At the same time, wiring line (c)
The contact (T 2 ) of (d) is opened and the operation of the auxiliary relay (R 2 ) is stopped to open the contact (r 2 ) of the wiring line (e) (f), but the auxiliary relay (R 3 ) is already open. Is activated wiring line (e)
Since the self-holding contact (r 3 ) in (f) is closed, the circuit protection timer (T 2 ) and the time setting timer (T 3 ) continue to operate. In this state, the time setting timer (T 3 ) starts contacting (t 3
3 ) is opened and the continuity of the wiring line (f) (g) is cut off.
Therefore, the circuit protection timer (T 2 ) returns to zero, the contact (t 2 ) of the wiring line (h) is opened, and the operation of the auxiliary relay (R 3 ) is stopped. At this time, the wiring lines (c) and (d) are conducted. Then, the self-holding contact (r) of the wiring line (e) (f)
3 ) is opened, the time setting timer (T 3 ) is reset to zero, and the solenoid valve (14) is closed to feed water to the water pipe (7).
