The system monitors for a high water level condition, a low water level condition and a Low-Low Level condition for Heater Cut-Off. These conditions have three outputs each which will:

  1. Close a set of dry contacts for the BMS
  2. Operate a relay rated at 30AMPS for 250VAC
  3. Turn on an LED to indicate the sensor has tripped.
  4. Activates when the water falls to a lower set point than the low alarm.
  5. When this fourth set point activates it shall remove power from the Heater in the basin by:
    • Open a normally closed relay
    • Close a set of dry contacts
    • Turn on a red LED.

The SWS6000 includes visual displays indicating power to the level control panel, when the control panel is actively filling, high and low water alarms and when the control panel has disengaged the heater in the catch basin.
The Fill dry contacts can be used as a comparative to develop a baseline benchmark of water usage for the system.

*Custom Sensors lengths available upon request.
