Sensor Model Normal Contact State
LS600LD Series OPEN (see note 1)
LS600 (Striped wire pair) OPEN (dry state, see note 2)
LS600 (Solid Color wire pair) CLOSED (dry state, see note 2)
LS600-S OPEN
LS610 CLOSED
RSU800 CLOSED
Note 1: The LS600LD Series is shipped from the factory as normally open unless otherwise noted.
This sensor’s normal state is field reversible. Simply remove the E-clip from the bottom of the
sensor and then remove the plastic cap. Remove the float and flip the float upside-down and
reinsert the float into the bottom of the sensor. Reinstall the plastic cap and E-clip and the sensor
will now operate as a normally closed sensor.
Note 2: The LS600 defaults to the normally open OPERATIONAL state unless otherwise
specified. The operational state differs from the dry state in that the dry state is with the float in
the down position whereas the operational state varies for a give float. The Overfill (Gray), High
High (Violet), High (Blue), and Pump Stop (Red) floats are operationally down or dry. The Pump
Start (Orange), Low (Yellow), and Low Low (Brown) floats are operationally up or wet. Keep this
in mind when deciding whether the LC1000 input state is open or closed for a particular sensor.
Also keep in mind that it is possible, with factory guidance, to reverse the state of most LS600
floats. See Bulletin 193 for complete details on this particular sensor model.
