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.
