IFS Single Phase Duplex Capacitor

Single Phase Duplex Capacitor (Start/Run)

ifs duplex capacitor

Single phase, duplex demand dose, float or C-Level™ controlled system for pump control and system monitoring.

The IFS single phase duplex capacitor (start/run) control panel is designed to alternately control two 120, 208, or 240 VAC single phase pumps in water and sewage installations. The alternating action equalizes pump wear. In addition to the alternating pump control, this system provides override control should either pump fail.

The IFS single phase duplex capacitor (start/run) control panel features a simple, easy-to-use touch pad on the inner door for programming and monitoring pump and float operation.

The optional C-Level™ sensor is a pressure transducer that senses the liquid level in the tank and sends a signal to the IFS panel. Pump activation levels can be adjusted by using the panel touch pad. C-Level™ CL40 sensor operating range is 3-39.9 inches (7.6-101.3 cm). C-Level™ CL100 operating range is 3-99.5 inches (7.6-252.7 cm).

Touch Pad Features:
  • Level Status Indicators illuminate when floats or set points are activated. Alarm will activate if a float operates out of sequence.
  • HOA (Hand-Off-Automatic) Buttons control pump mode with indication. Hand mode defaults to Automatic when stop level or redundant off level is reached.
  • Pump Run Indicators will illuminate when pumps are called to run.
  • Lead/Lag Selector toggles pump operation (alternate 1-2 and 2-1).
  • LED Display shows system information including: level in inches or centimeters (C-Level™ only), mode, pumps elapsed time (hh:mm), events (cycles), alarm counter, float error count, timed dose override counter (timed dose only), and ON/OFF times (timed dose only).
  • NEXT Push Button toggles display.
  • UP and SET Push Buttons set pump ON/OFF times (timed dose only) and activation levels (C-Level™ only).
