plied to the pump motor within 0.4 secs.
2. Although the voltage supplied to the pump motor is in a
high level, motor relay will not actuate for 2.5 secs, or
13 more.
3. The voltage supplied to the pump motor keeps low level
for louger than 0.4 secs. and the pump repeats activat-
ing for 7 secs. 3times maximally. After the last activation,
