Nelsen Prog Sys Cord, 3 & 4 Tk, 12'

The Nelsen Progressive System Cord wires together the controllers on 3- and 4-tank arrays. Part CL-COM-34-12 is a 12-foot communication cord that connects the control valves in a three- or four-tank progressive-flow system so they stage into service in the correct sequence.

• Manufacturer: Nelsen Corp
• Part number: CL-COM-34-12 (alternate V4245-12)
• Length: 12 feet
• For: 3-tank and 4-tank progressive systems
• Function: interconnects valve controllers for staged operation
• Progressive-flow demand communication cord

In a progressive-flow arrangement, tanks are brought online one after another as demand rises and are rotated so no single tank carries the entire load, and that choreography depends on the controllers talking to each other. This cord is the wiring link that carries the staging, lead, and lockout signals across the array so tanks activate and regenerate in turn. The 12-foot length spans the controllers on a typical three- or four-tank skid or wall layout without excessive slack. Match the connector type and supported tank count to your existing progressive control heads before installing, and keep the cord clear of drain lines, salt, and high-voltage wiring. A correct-fit replacement for a damaged progressive communication cord or a spare for commissioning a new multi-tank system.

Power for a Multi-Tank System

This Nelsen Progressive System Cord supplies power and signal between the control valves in a multi-tank progressive setup, wired for three- and four-tank configurations at a twelve-foot length. In a progressive system, several tanks share the load and bring additional capacity online as demand rises, and they need to communicate to stagger their service and regeneration properly. This cord is the physical link that carries that coordination from valve to valve so the tanks work as one system rather than fighting each other.

Why the Right Cord Matters

The connecting cord is easy to overlook until it fails. A cracked jacket, a corroded pin, or a cord damaged during a move or a repair can leave tanks unable to talk to one another, which shows up as tanks that regenerate at the wrong time, do not switch as expected, or drop out of the rotation entirely. Replacing the interconnect cord with the correct three- and four-tank version restores that communication and gets a progressive system back into proper sequence.

Match It to Your Setup

Because progressive controllers differ, the number of tanks and the cord length both have to line up with your equipment. Tell us how many tanks you are running and the layout between them, and we will confirm this cord is the right one before you order. Getting the correct version the first time saves you the frustration of a system that will not sequence. We include the reference material we have on hand, and the Water Softener Plus team can help you route and connect the cord so your progressive system resumes coordinated operation.
