Demand Dose Control Panels

Simplex or duplex control switch for dewatering, effluent and sewage applications

Features and Benefits

Clarus Environmental’s variable level control switches can be used to monitor liquid level conditions and activate control panels or alarms in pump chambers, dose tanks, sump pump basins, holding tanks, lift stations, and other non-potable water applications. The variable level control switch is normally open when hanging vertically above the liquid level. When the water level rises and the switch is raised a few degrees above the horizontal position the switch closes, completing the circuit to the control panel or alarm. The float that encases the mechanical switch is constructed of durable PVC/polypropylene. Cord lengths of 15’, 25’, 35’, and 50’ (5, 8, 11, and 15 m) are available.

  • For use with control panels and alarms in non-potable water applications
  • Standard variable level switches rated for 115/230V, 5 Amps
  • Low current variable level switches rated for 125 VAC/30 VDC, 0.1 Amps
  • Standard switches include 18/2 Type SJOW CPE cord
  • Switches are rated for environments up to 140F (60C)

SEQUENCE OF OPERATION FOR SIMPLEX PANEL

  1. Operation can begin after the following:
    • Correct voltage is supplied to panel
    • A good ground is supplied to panel
    • Pump is connected correctly to panel
    • Panel circuit breaker is closed
    • Floats are installed properly
    • Overload protection is adjusted to pump nameplate amps
    • Pump HOA switch is set to “Auto”
  2. When the “Stop” and “Start” floats are closed the pump will energize and the External Pump Run Light will illuminate. The pump will remain operational until the “Stop” float opens.
  3. In the event the liquid level continues to rise the “Alarm” float will be closed. When the “Alarm” float is closed the following will occur:
    • The External High Water Light will illuminate
    • The Audible High Water Horn will sound
    • The Auxiliary Dry Contacts will close
  4. The Audible High Water Horn can be silenced by pressing the Alarm Silence Button. When the “Alarm” float is opened the External High Water Light, Audible High Water Horn and Dry Auxiliary Contacts will be reset.

*A Three Phase Panel has a multi-tap transformer with secondary fusing.

    Part Number Chart
    An electrical control panel is used on a simplex pump application where automatic electrical cycling of the pump is desired for added protection in residential or commercial applications. The built-in alarm system, a standard feature, will activate when the water level becomes unusually high. All electrical systems must be installed by a qualified electrician and according to the National Electrical Code. (See Section 430-71 through 430-113, plus any others that apply.)
