The 3200NXT Network Controller links multiple commercial valves using off-the-shelf CAT3, CAT5, or better cables for various system types. It is configured for use with Fleck® 2750, 2850s, 2900s, 3150, and 3900 Control Valves and supports stager valves with butterfly or notched cams.

System Types

• System 4 (Single Valve): Time Clock, Delayed, One Meter Immediate, One Meter Remote Signal Start, Optional Meter
• System 5 (Interlock, 2-4 Valves): Immediate, All Meters, Remote Signal Start, Optional Meter
• System 6 (Series, 2-4 Valves): Immediate, All Meters, Remote Signal Start, Optional Meter
• System 7 (Alternating, 2 Valves): Immediate, One Meter, Remote Signal Start, Optional Meter
• System 9 (Alternating, 2-4 Valves): Immediate, All Meters, Remote Signal Start, Optional Meter

Regenerant Flow

• Downflow, Upflow Brine First, Upflow Brine Refill First

Generic Meter Guidelines

• Open collector output.
• Pulse rate generated must not exceed 100 pulses per second (100 Hz), or 6,000 pulses per minute.
• Support for meter outputs in the range of 1-255 gallons (25.5 m³) for every 1-255 pulses (e.g., 35 gallons/100 pulses).
• Meter must operate at 5 VDC.

Electrical Rating

• Transformers: 24 VAC Pentair® Transformers
  • 115 VAC +/- 20% input, 24 VAC output
  • 230 VAC +/- 20% input, 24 VAC output

Humidity

• 95% RH, Non-Condensing
