The Centurion™ program relies on the lead-lag sequence to control the steps necessary to regenerate multiple water softeners. Each softener has a flow meter with a computerized totalizer. The operator can set the volume of water to be treated by each softener to allow full utilization of the softening capacity of each softener (called demand regeneration). At low flows, the system is designed for the unit with the least capacity remaining to be the lead unit or first on line. As the flow increases, the other units are brought into service based on demand (flow) and capacity remaining in each unit. As the flow decreases, all units in service remain in service until the lowest possible flow. This gives minimum leakage by operating at the least possible flow that still prevents channeling. Each unit has two set points, a minimum and a maximum or a lead and a lag. Demand regeneration allows maximum utilization of resin capacity thereby minimizing salt and rinse water requirements.
The Centurion™ can operate either a valve nest or a bank of Task Master™ valves. Water King incorporates manufactured products by Allen-Bradley. Allen-Bradley products can be serviced anywhere in the world thus minimizing downtime if repairs are needed. In addition Allen-Bradley has the best longevity in controller systems. A perfect match to Water King’s longevity in the soft water business. The Task Master™ valve has been modified to provide full position indication, when used with the Centurion. The Task Master™ valve / Centurion verifies all five softening cycles – service, backwash, brine, slow rinse and fast rinse.

Centurion™ and Task Master™: |

The tried and true five cycle Task Master™ valve has just stepped into the new century. The Task Master™ has always been a rugged, reliable, easily repaired water softening and filtration valve. Previous generation of controllers sent a regeneration signal to the valve to begin timed cycling of the valve. With the Centurion™ the electromechanical timers have been eliminated. All timing, sequencing, and programming is done by the real time clock in the PLC. The electrical portion of the Task Master™ has been greatly simplified by elimination of the timer on each valve. More importantly, the Task Master™ / Centurion™ system now has full position indication. The reliable positioning system using opposing switches operated by a cam remains. Position indication cams are now available. These provide positive feed back to the Centurion™. Position indication allows for error detection in valve sequencing. Position indication on a five cycle valve is an industry first. Centurion™ - Valve Nest: |

A valve nest for a softener has six valves. These are controlled by a stager for each vessel. The Centurion™ provides demand regeneration, lead-lag unit sequencing, and independent brine control, for up to four softeners. Water King can provide a valve nest using pneumatically or hydraulically operated diaphragm valves or electric valves depending on customer’s requirements. Specific control of brining by PLC is included. An auxiliary contact is available for operation of a brine pump or brine feed valve. |
