Hydroelectric, Power & Water Systems
Drainage and dewatering pumps help manage water in sumps and auxiliary spaces when operated according to the plant procedure. PLC automation can select duty and standby pumps, use level feedback to request starts and stops, monitor motor protection status and alert operators when a pump fails to start or a level continues to rise. Automation scope depends on the equipment, operating sequence, existing controls and process requirements. Share the machine details and desired outcome to define a suitable control approach.
Document whether the level instrument is a continuous transmitter, discrete switches or both, and what happens when readings disagree. Define start proof, alarm delay, overload lockout, standby eligibility and manual reset. An operator should be able to see the sump level, selected duty pump, run state and reason a start was inhibited.
Drainage and dewatering pumps help manage water in sumps and auxiliary spaces when operated according to the plant procedure. PLC automation can select duty and standby pumps, use level feedback to request starts and stops, monitor motor protection status and alert operators when a pump fails to start or a level continues to rise.
The PLC may select duty and standby pumps by an agreed rotation rule while respecting availability and operator mode. Automatic standby start should be conditioned on the sump arrangement, pump permissives and site-approved procedure.
High level can initiate a duty pump and a rising level can request standby assistance if permitted. Low-level stop hysteresis creates separation between start and stop thresholds to reduce rapid cycling; values must reflect sump geometry and pump behavior.
Run feedback, overload/trip, starter-ready, start timeout and level-sensor validity can be monitored when wired or communicated. Dry-run protection is included only where applicable to the pump/source arrangement.

Request service quote →A configured high-level input or transmitter threshold can request the duty pump after mode and equipment permissives are satisfied. A continued rise can request standby assistance if that action is approved for the installation.
Separating the start and stop thresholds provides hysteresis, reducing rapid pump cycling as level fluctuates near a single threshold. The actual values depend on the sump and pump arrangement.
The PLC can alarm on missing run feedback or overload/trip and, where permitted, make the standby pump available under the defined sequence. Reset and investigation requirements should follow site procedure.
