Alarm Controls:
The alarm level is usually set
above the override level so
the alarm will signal only if the
override level is exceeded.
However, some engineers prefer
to have the alarm level set below
the override level as it is possible
for one pump to fail and the other
pump to operate on the override
level with the sump level never
reaching the alarm level. This is
particularly true in cases of low
inflow capacity.
Electrical Control Panel:
It is recommended that the
Hydromatic control panel be used
with all pumps as proper starter
heaters and connections for heat
sensor wires are furnished.
IMPORTANT: If Hydromatic
electrical controls are not used
and the motor fails because of
set at turn-on for one pump, and
one set for turn-on for two pumps.
Pumps alternate operation on each
successive cycle.
Two pumps operate together only
if sump level rises to the third or
override control. The override
control also brings on the second
pump in case of failure of the first
pump. Extra floats with
appropriate controls can be
supplied for alarm functions.
Triplex systems use four controls:
one set at turn-off, one set at
turn-on for one pump, one set at
turn-on for two pumps, and
one set at turn-on for three
pumps. Pumps alternate each
successive cycle.
Three pumps operate together
only if sump level rises to the
fourth control (second override).
This control also brings on the
third pump in case of failure
of either or both of the first
two pumps.
improper components or if the
heat sensors are not properly
connected the motor guarantee
is void.
Hydromatic electrical equipment
is installed in a weather-proof
NEMA 3R enclosure. The
electrical equipment includes a
maincircuit breaker for each
pump, a magnetic starter with
overload protection for each
pump, an H-O-A switch and run
light for each pump, an electric
alternator and a transformer to
provide appropriate control
for control circuit and alarms.
Overload Heaters:
If the Hydromatic electrical panel
is not used, starters with 3 leg
overload protection must be
supplied. On 3 phase pumps the
heaters must be sized in
accordance with the nameplate
