LS8000/2 DUAL POINT
LEVEL SWITCH
1. DESCRIPTION
A. General Description
The LS8000/2 dual point level switch is designed to sense material at two points in a tank, hopper or sump. The
unit consists of a receiver which may be remote mounted from the sensing probe(s).
The receiver is designed to work in 4 different modes:
1. Sense 2 points along a vertically mounted probe and maintain a level between them. (Fig 1A)
2. Control 2 separate probes in the same tank and maintain a level between them.( Fig 2A)
3. Control 2 probes in different locations. (Fig 3A)
4. Four set points on one probe. (See page 10 )
The receiver has 3 SPDT 5 amp relays for control: one relay for the high set point, 1 for the low setpoint and a
latching relay for automatic filling or emptying between the 2 setpoints. The latching relay would not be used if
configured as Fig. 3A.
Whenever the LS8000/2 is used in the “2 points or 4 points on 1 probe” configuration, a coated probe (not bare
steel rod) must be used.
