IMPORTANT CONSIDERATIONS FOR DC-
POWERED OPERATORS
z
Since the operator is intended to run on
batteries, control of the load is important. Gates
that move easily and do not bind will drain less
energy from the battery, preserving capacity for
more cycles during a power failure.
z
Be certain to observe polarity when connecting
the batteries or adding accessories. Reversed
polarity may result in a non-functional operator
or damage to a component. Red (+) is positive
and black (-) is negative. If shorted, the batteries
will generate a very high current. The batteries
are connected in a series circuit: Join the positive
(+) terminal from one battery to the negative (-)
terminal of the next battery.
z
Batteries have a finite life and age more quickly
when exposed to temperatures above 80°F
(27°C). Battery temperatures above 104°F (40°C)
are damaging and significantly shorten battery
life.
z
As the batteries age, they will progressively lose
their capacity to store energy. If the total amount
of back up capacity is critical, plan to replace the
batteries after two years of use especially in hot
climates. Properly discard used batteries.
Refer
to page 15.
WARNING
Batteries contain sulfuric acid. Acid in your
eyes, on your skin, or on your clothing can
cause injury and severe burns. If batteries
are dropped or damaged dispose of them
properly.
POWER
z
Batteries are rated to perform to capacity at
certain temperatures. Variations in temperature
affect performance of the batteries. An example
of amp hour performance is shown in Table 7
.
HySecurity mounts the battery pack near the
transformer to provide residual heat around the
batteries which guards against amp hour loss in
colder climates.

z
HySecurity uses a permanently sealed AGM-
type battery which last much longer than wet
cell batteries and needs no maintenance over
its life span. Batteries are protected from over
discharge by a low voltage sensing circuit. The
charger circuit regulates to allow high charger
output when the battery is partially discharged.
The charger circuit automatically reduces the
output to near zero as the batteries become
fully charged.
NOTICE
The SwingSmart operator stores all User and
Installer Menu settings in non-volatile memory
(EEPROM). Configurations are saved if a
power loss occurs and reinstated once power
is restored.
