DCR-1006A Level Controller Rev. B2, 7/15 <br /> Wiring the Switched Input for High/Low Level Backup <br /> The DCR's Switched Input can be connected to simple switching device, such as <br /> a float switch, to provide a high/low level backup and prevent dry pumping or <br /> overflow conditions in the event of an ultrasonic sensor failure or malfunction. <br /> Normally Open Switched Input <br /> (Emergency Stop) <br /> Relay Controlling Trip 1 (NO) is controlled by the sensor <br /> Pump/Valve, (see RelayTripTypes and RelayLogic <br /> Switched Relay Controlled ontrolled yp g <br /> Input by Switch Inputb Sensor Diagrams on pages 32-33), closing for <br /> ON conditions. If the NO input switch <br /> closes, Trip 2 will open, breaking the <br /> IN GND N.O. COM N.C. N.O.
