INSTALL SOLAR PANEL(S)

SELECT SITE FOR SOLAR PANEL(S)
The solar panel(s) must be located in an open area clear of obstructions and shading for the entire day. The solar panel(s) comes with a 10 foot (3
m) cable. If a location near the control box cannot be found, an additional cable will be required. The LA412DC Solar Gate Operator is not supported in
northern climates where temperatures reach below -4° F. This is due to cold weather and a reduced number of hours of sunlight during the winter
months. Cycle rate may vary from solar chart for areas that reach below 32° F. Solar panels should be cleaned on a regular basis for best performance
to ensure proper operation.
SOLAR USAGE GUIDE
The LA412DC has industry leading solar performance due to highly efficient electronics that draw very little power while the gate is not in use
(standby).
Typical System Standby Battery
Current Consumption (mA)
5 mA
+1 mA
+2 mA
+14 mA
+2 mA
This low current draw drastically increases the number of days the operator can remain in standby. To determine your system's performance,
reference the above table and determine how many milliamps (mA) your system will draw from the batteries.
EXAMPLE 1: A system with only a main control board and one or more hand held remote controls programmed will draw 6 mA from the batteries
while the system is in standby.
EXAMPLE 2: A system with only a main control board, one or more hand held remote controls programmed, and 20 mA of external accessories
connected to the main control board's accessory power output will draw 26 mA from the batteries while the system is in standby.
EXAMPLE 3: A system with a main control board, expansion board, two loop detectors, and one or more hand held remote controls programmed will
draw 24 mA from the batteries while the system is in standby.
