BASIC INSTALLATION HINTS AND RULES
PLEASE READ THIS SECTION VERY CAREFULLY BEFORE BEGINNING YOUR
INSTALLATION
1.
UNDERSTAND THE SYSTEM AND INSTALLATION SITE THOROUGHLY.
The SL 1000 is a
flexible and reliable gate operator system, but the quality of service depends directly on the
quality of installation. Please read these instructions carefully and study the applicable diagrams
before planning your installation. In particular, understand any site characteristics that may
affect the system installation.
WARNING
2.
INSTALL PERMANENT WIRING.
U.L. specifications require the model SL 1000 system to be
permanently wired. Refer to your local wiring code for specific information.
WARNING:
Damage caused by faulty wiring is not covered by warranty.
3.
U.L. OBSTRUCTION-SENSING REQUIREMENTS.
To maximize safety, U.L. 325 standards
require primary obstruction sensing (gate sensitivity to impact) and secondary obstruction
sensing (photo-sensors) be in operation at all times.
4.
GROUND THE SYSTEM.
The system contains parts which may be damaged by static
discharge. A proper earth ground connected to the gate operator housing (at the lower left
grounding screw shown in Figure 15) will significantly reduce the chances of damage or
improper operation. The shielding in the cables specified for all remote sensors and controls
should also be connected to earth ground at the controller end of the cable only.
To be effective, the ground connection must be made by running 12 awg copper wire to a good
ground point (e.g., an electrical panel, a metallic cold water pipe that runs into the earth, or a
grounding rod at least 10 feet in length that is driven into the earth) within 12 feet of the system.
Even if you have a good earth ground, you should try to discharge any static before handling the
boards.
WARNING:
Damage caused by static discharge or lightning is not covered by warranty.
5.
PROVIDE POWER FROM A DEDICATED SOURCE.
The outlet into which you connect the
Gate Operator should be wired to its own circuit breaker. This will reduce the line noise
introduced into system power and minimize the risk of having other equipment interrupt system
operation. In a Master/Slave system, master and slave must each have separate circuits.
6.
DO NOT OVERLOAD THE TERMINAL BLOCKS.
The terminal blocks are removable and the
pins are soldered into the boards. To connect your wires, remove the “head” from the correct
terminals and open the screws. Insert the wire into the correct opening on the front and tighten
the screw until the wire is held firmly. When you have made all connections for a given “head”,
plug it back onto the inputs designated for that terminal block.
Stranded wire must be between 16 and 24 awg. Solid wire must be between 18 and 24 awg.
This is the total thickness measurement so, if you are putting two wires in, the combined
thickness must fall within this range.
NEVER
try to insert more than two wire per terminal.
7.
ENSURE GOOD CONNECTIONS.
A light tug on the wire will tell you if the connection is secure.
When reconnecting system components, make sure all pins are straight on chips, connectors,
and terminal block heads.
8.
READ MARKINGS CAREFULLY.
The connection points are marked on the boards clearly.
Before making any connection, be sure to read the marking and check it against the
corresponding figure in these instructions so that you understand the connection you are making.
9.
TRAIN YOUR CUSTOMERS THOROUGHLY.
Although customer responsibility is limited to
proper installation, the quality of service is determined by care of system programming. Ensure
that the customer has a copy of this manual to guide them. It will save you and them lots of
inconvenience and aggravation later.
