LIGHTNING PROTECTION
For areas where a high probability of ground lightning strikes exists
(Florida, Georgia, etc.,) additional lightning protection should be
installed in the RS4000. Although it may not be possible to protect
against all strikes, additional protection will substantially reduce the
occurrence of lightning damage. Allstar’s lightning data indicates that
the most strikes enter the RS4000 through the power lines. Effective
protection requires that the surge current from the lightning strike be
shunted to ground. This must be done without raising the potential of
the circuitry in the RS4000, with respect to ground, to the levels that
will damage the solid state circuitry. Lightning strikes generate
enormous currents for very short periods of time. Unfortunately, the
period of time is long enough to damage solid state components and
many times, other components. The key to success is a very low
resistance path from the surge protector to ground for these currents
in addition to a surge protector that will act fast enough to protect the
solid state circuitry. Several manufacturers offer suitable surge
protectors.
RIGHT HAND AND LEFT HAND INSTALLATION
The RS4000 operator is wired at the factory for RIGHT HAND
operation. Right hand operation is described as the gate swinging in
and to the right and where the operator is mounted to the right of the
gate leaf - both as you look at the installation from the inside (secured
side). See Figure 4 for a pictorial example of a right hand operation.
Left hand operation is described as the gate swinging in and to the left
and where the operator is mounted to the left of the gate leaf - both as
you look at the installation from the inside (secured side). Figure 7
diagrams depict gates and operators in a left hand set-up.
Note the different wiring configurations for right-hand installations
and left-hand installations (see Figure 13). To change to a different
handed operation the capacitor wires and limit wires must be
changed. For proper operation, the limits and capacitor must be
wired as shown.
SYNCHRONOUS OPERATION (MASTER/SLAVE)
Two RS4000 units in a bi-parting situation (one wired right-hand and
one wired left hand, see above) can be configured to operate in a
synchronous manner. The units can be wired together to operate as
one system, with one unit controlling the movement of both.
Additionally, the installer can customize the installation of the
external entrapment protection devices. These devices can be wired
to the primary (controlling) operator or alternately to the individual
units as the situation dictates or the end user requires.
When an external entrapment protection
device is wired to the primary unit (such as
would be recommended for a photoelectric
beam across the entire opening) both units
will react to the detection of an obstruction,
regardless of the location of the obstruction.
An edge device (or similar) protecting an
entrapment zone particular to the secondary
unit could be wired to that unit only and
would react individually to the detection of an
obstruction. Synchronous movement would
resume once the obstruction is cleared and an
open or close command is received by the
primary operator.
To obtain synchronous operation (4 Steps):
1. Wire the Primary Operator Terminal #14 to
Terminal #6 in the Secondary Operator.
2. Wire the Primary Operator Terminal #15 to
Terminal #7 in the Secondary Operator.
3. Place the Master/Slave Jumper on the
Primary Operator motor control board to the
primary (Master) position. See Figure 19,
Page 18.
4. Place the Master/Slave Jumper on the
Secondary Operator motor control board to
the secondary position. See Figure 19, Page
18.
C: INSTALLING THE OPERATOR
WARNING!
TO REDUCE THE RISK OF DAMAGE DUE TO
LIGHTNING, ENSURE A SOLID GROUND FROM
THE TWIST’R GROUND WIRE IN THE SERVICE
ENTRANCE 2 x 4 HANDY BOX TO THE
ELECTRICAL SERVICE GROUND OR TO A
EARTH GROUND STAKE NEAR THE TWIST’R.
