SB(…)E automatic water-level control function
➢
Pump starts to work when the pump power is on, and water-level sensor is ON.
➢
During pump operation if water-level sensor is OFF, pump will continue to work for
60s and stop. But if water-level sensor is ON again during this 60s, the pump will
continue to operate without stop.
➢
When the pump is stopped due to low water-level, it will not start again within 60s
even if water-level sensor is ON, unless pump is powered off and on again.
