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

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
and CSA approvals. The case and
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.
