The LV600 Series unique float level 
switches provide an economical 
means of pump-up/pump-down 
level control with just one level 
switch. The ON/OFF differential is 
set by adjusting the length of cable 
over which the LV600 is allowed to 
float. Depending on whether the 
LV600 is floating with the cable UP 
or DOWN (see drawing), the 15 
amp relay is on or off. The relay 
changes state when the LV600 is 
above or below the fixed point by 
80% of the cable length. For 
example, if the cable is fixed for 
3 m (10') of free cable, the LV600

will trigger at 2.5 m (8') above 
and below the fixed point. Thus, 
turbulence will generally not 
cause false switching.
The cable can be fixed to a pipe, 
or the accessory counterweight can 
be used by slipping it over the cable

more than 100,000 times. The 
internal microswitch relay carries UL

cable are hermetically sealed by a 
two-step plastic injection molding 
process to ensure a leak-tight seal.

Caution:
Level switches are manufactured to the 
highest quality specifications. However, 
due to their economical construction, they 
should be used only for applications 
where, in the event of product failure, the 
risk of damage to equipment or personnel 
would be minimized. In the case of level 
switches, one or two back-up switches 
should also be used to insure that failure 
of any one switch will be mitigated by the 
back-up level switches. The user should 
periodically inspect the product’s 
performance in the actual application. Use 
of the products beyond the recommended 
capabilities and lifespan are specifically 
not recommended.
