wire with ground. Be sure ground
wire is con nect ed to a water pipe
or ground stake. The auxiliary
cable for seal fail ure and heat
sensors is four wire color coded.
Seal Failure:
An electrode probe is installed in
the seal chamber so if any water
enters the chamber through the
first seal the electrode will be
energized and a sig nal will be
transmitted to the sens ing unit at
ground surface causing a red light
to turn on. The electrode probe is
installed in all units but the
sensing unit is supplied at extra
cost and must be ordered.
In operation the seal failure unit
in di cates only that there is some
water in the seal chamber. The
pump will con tin ue to operate
without damage but the seal
should be checked im me di ate ly
after failure is indicated.
The sensing unit is recommended
on all installations as good
insurance against motor failure.
Heat Sensors —
Standard Equipment:
All motors have heat sensor units
em bed ded in the motor winding to
detect excessive heat. The heat
sen sors are set to trip at 150°C
(302°F), so will not op er ate unless
dangerous heat occurs. The
sensors automatically reset when
mo tor cools to safe tem per a ture.
The sensors are connected in
series with the motor starter coil
so that the starter is tripped if heat
sensor opens. The motor starter is
equipped with overload heaters so
all normal over loads are protected
by the starter.
Sump Level Control:
Sump level is controlled by
Hydromatic float switch con trols.
