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
(see drawing). The mechanical
SPDT switch has no potentially
dangerous mercury, is rated for
15 A at 250 Vac, and can switch
more than 100,000 times.
The internal microswitch relay
carries UL and CSA approvals.

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.
