IMPORTANT SPECIAL NOTES REGARDING
D.C. POWERED GATE OPERATORS
The on/off switch on the electric control panel of the drive unit does not disable all DC power to the
operator, even if the AC power has been disabled at its source. The large rotary switch in the DC power
supply enclosure must be actuated off to insure disconnect of all DC power to the drive unit.
The disconnect in the power supply must be off if the AC source power will be absent for more than one
week. This avoids slowly discharging the batteries into the battery charger. Batteries will self-discharge
and therefore the DC power supply must not be stored for a period longer than 6 months without
recharging the batteries.
Batteries contain sulfuric acid. If batteries are dropped or damaged, be cautious not to get acid in the
eyes, on skin, or on clothing.
Be certain to observe polarity when connecting the batteries, or adding accessories. Reversed polarity
may result in a non-functional operator or possibly damage a component. Red is (+) positive, and black
is (-) negative.
Since the electrical current under load is very high, be certain that the minimum conductor size, specified
in the installation instructions, is used for the connection between the battery pack and the operator. If
the battery pack is more than 20 feet from the operator, use a larger wire size, according to the distance
between the operator and the batteries.
If shorted, batteries will generate a very high current. Observe special care when connecting the cables
to the batteries that the polarity is correct. The batteries are connected in a series circuit: join the positive
(+) terminal from one battery to the negative (-) terminal of the next battery.
Since the operator is intended to run on batteries, control of the load is important. Easier moving gates
will drain less energy from the battery, preserving capacity for more cycles during a power failure.
HySecurity uses a permanently sealed type battery, which needs no maintenance over its life span. A
low voltage-sensing circuit protects the batteries from damage which could be caused by over-discharge.
The charger automatically regulates its output to allow high output when the battery is partially
discharged. The output will automatically be reduced to zero as the batteries become fully charged.
Batteries have a finite life. As the batteries age, they will lose some of their capacity to store energy. If
the total amount of back up capacity is critical, plan to replace the batteries after 5 years of use. Properly
dispose of or recycle used batteries.
Batteries are rated to perform to capacity at a temperature of 77 degrees Fahrenheit. Below 77 degrees,
the "amp hour" capacity is temporarily reduced. For example, at freezing, the capacity is 75%, at 10
degrees Fahrenheit, the capacity is 50%. HySecurity insulates the battery pack to guard against this loss.
Do not remove any insulation or the performance of the system may be adversely affected.
Batteries can be damaged by excessive heat, which may shorten their life span. Therefore, do not paint
the battery enclosure a dark color that could cause it to absorb a lot of heat from sunlight.
DC Motors contain carbon brushes which wear over time and must be replaced. Failure to replace the
brushes will result in damage to the DC motor. Brushes should be replaced every 5 years, or sooner in
high use and/or severe duty installations.
