  • Features and Benefits

    Zoeller Pump’s timed dose control panels provide residential and commercial customers with a reliable means of controlling single phase pumps in onsite installations. A programmable timer activates a magnetic motor contactor to turn the dose pumps on and off. A high or low water condition will override the timer to turn the pump on or keep the pump from running dry. An alarm float activates the audio/visual alarm system, indicating a high liquid level. Simplex or duplex models are available. Panels also include a Test/Normal/Silence switch, which allows the horn and light to be tested or silenced in an alarm condition. Common applications include media filter systems, pressure distribution systems, mound systems or any application requiring a timed dose. Custom panels available.

    • NEMA 4X enclosure, UL listed
    • Panels include three 20’ (6 m) control switches
    • Exterior Alarm Test/Normal/Silence Switch
    • 2 year limited warranty

    Notes

    All variable level float switches for these control panels are mechanically activated and do not contain mercury.
    Products may not be exactly as pictured.
    Tested to UL Standard UL 508 & Certified to CSA Standard C22.2 No. 205.

    All Zoeller Pump products must be installed and maintained in accordance with all applicable codes.

  • Literature

    Specifications:
    Enclosure: 10” x 8” x 4” (Simplex); 14” x 12” x 6” (Duplex), NEMA 4X, watertight, noncorrosive engineered thermoplastic.
    Alarm/Control Section Voltage: 120 VAC, 60 Hz, single phase, 40 watt maximum (alarm condition).
    Pump Section:

    • 120 Volt Models – 120 VAC, 60 Hz, single phase, 0 – 20 FLA
    • 230 Volt Models – 230 VAC, 60 Hz, single phase, 0 – 20 FLA

    STANDARD FEATURES

    • UL Labeled: Entire control system (panel and switches) meets and/or exceeds industry safety standards
    • Complete Packages: Panels include low level cutout, timer override and high water alarm variable level float switches
    • Installation Instructions: Complete step-by-step instructions allow for easy installation
    • Lockable Latch: Added security and protection for your system
    • Two-Year Limited Warranty: Our commitment to customer satisfaction
    • Redundant off circuit (redundant off float sold separately): Protection against primary switch failure
    • Event Counters: Allows monitoring of pump cycles
    • Elapsed Time Meter: Allows monitoring of hours run

    SEQUENCE OF OPERATIONS FOR SIMLEX TIMED DOSING

    1. Operation can begin after the following:
      • Correct voltage is supplied to the panel
      • A good ground is supplied to the panel
      • Pump is connected correctly to the panel
      • Panel circuit breaker is closed
      • Floats are installed properly
      • Pump HOA Switches are set to “Auto”
      • The control panels are available for use with two, three, or four float combinations.
    2. In a two float system, one float in the tank is the “Low Level Cutout” float while the other is a “High Level Alarm” float. The normal operating level should be between the “Low Level Cutout” position and the “High Level Alarm” position.
    3. When the “Low Level Cutout” float switch is closed, the pump will be ready to energize. The pump will become operational by using the “On/Off” timer.
    4. In the event the liquid level continues to rise, the “Alarm” float switch will be closed. When the “Alarm” float switch is closed, the following will occur:
      • The external high water light will illuminate
      • The audible high water horn will sound
    5. The audible high water horn can be silenced by flipping the alarm silence switch. The horn silence relay automatically resets the alarm after the high water condition has been resolved.
    6. The three float system adds a “Timer Override” float. The “Timer Override” float gives you the option of pumping from the basin while the timer is in the “Off” cycle. It is only intended for times of abnormally high liquid level inrushes. The normal operating level should be between the “Low Level Cutout” float and the “Timer Override” float.
    7. A four float system includes a “Redundant Off” float, a “Low Level Cutout” float, a “Timer Override” float and a “High Level Alarm” float. The “Redundant Off” float is positioned slightly below the “Low Level Cutout” float, but above the pump. The normal operating level should be between the “Low Level Cutout” position and the “Timer Override” position. The “Redundant Off” and the “Low Level Cutout” float switches must be closed for the pump to operate on the timer.
