Triplex Lift Station Controls
What changes when a station has three pumps: the lead, lag, and standby roles, rotation with three positions, the diminishing return of the third pump on the system curve, availability logic, and the power and panel arrangements that three pumps require.

Lift Station Lead/Lag Control
How a duplex or triplex station decides when one pump is enough and when it is not: the setpoint ladder, cycle volume, the lag call, parallel pumping, and what to do when the lead pump fails.

Lift Station Pump Alternation
Which pump leads, how the lead role rotates, what an alternator relay does, and why equal run hours are not always the goal. Includes the logic rules that keep alternation from causing trouble.

Lift Station High Level
The alarm that stands between a lift station and an overflow: where the high-level float goes, what it must do on its own, how much response time the well provides, and how to diagnose a high level that should not be happening.

Lift Station Backup Control
How a lift station keeps pumping when the transmitter, the PLC, or the SCADA link is gone: float backup logic, the control transfer relay, redundant-off protection, and how to test it with the controller actually dead.

Lift Station Generator Operation
Standby power at a lift station: what the transfer switch does, how the controls ride through the transfer, staggered pump restarts, what SCADA should see, load testing, and the portable generator connection.
