shunted to ground. This must be done without raising the potential of
the circuitry in the LPX1000, 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.
CONTROL AND ACCESSORY EQUIPMENT
WIRING
IMPORTANT - remove power from the operator before
attempting to connect an accessory device or control station.
All accessory equipment is hooked-up to
the 22 terminal barrier strip located
on the back of the control box. See
Figure 11. There are no installer
connections inside the control box.
NO ACCESSORY EQUIPMENT
SHOULD BE INSTALLED IN THE
CONTROL BOX!
If local electrical codes permit, use
the operator's bottom plate for
mounting accessory components.
Otherwise, install the accessory
equipment in an appropriate electrical
box.
The thirteen (13) command inputs for
the LPX1000 require a switch closure
to COMMON of less than 100
OHMS resistance and for more than
100 milliseconds duration. Two of
the inputs - ALTERNATE and
RADIO OPEN - are momentary
inputs where the signal must be
released and re-entered to be
recognized. The remaining inputs
can be continuous signals. A label on the left side of the control box
lists the function of each of the terminals on the barrier strip, see Figure
11. Also see the Reference Chart on Page 20 and 21.
WIRING A 3-BUTTON STATION
See Figure 13 for instructions on wiring a 3-button station.
NOTE: The STOP button is normally OPEN
BI-PARTING APPLICATION
In a bi-parting application, two operators are required, one operating in
a left-hand mode, the other in a right-hand mode (see page 15) to
control two gate sections that make up a single gate. Both must be
wired individually for AC power (as previously described) but share a
common set of input controls. In general, all of the instructions
concerning installation of individual operators can be followed in a bi-
parting application except the following:
Choose one of the operators to be the PRIMARY and the other to be the
SECONDARY. Route all of the control wiring to the PRIMARY
operator first. This will prevent grounding loop problems which can
occur when more than one COMMON or ground wire is attached
between separate operators. All accessory equipment should also be
wired to the PRIMARY.
Connect terminal #14 (MASTER OPEN) on the PRIMARY operator to
terminal #6 (OPEN) on the SECONDARY operator. Connect terminal
#15 (MASTER CLOSE) on the PRIMARY operator to terminal #7
(CLOSE) on the SECONDARY operator. Connect terminal #16
(COMMON) on the PRIMARY operator to terminal #16 (COMMON)
on the SECONDARY operator . Dual 1/4" disconnect terminals for
each input are provided for this purpose. Use conduit SEPARATE
from AC power service. See Figure 15 for the correct wiring.
Switch #3 of the Switch Selectable Options must be set to the proper
position, see page 17.
NOTICE: A separate 3-wire (HOT, NEUTRAL and GROUND),
115 VAC electrical connection is required for each operator in a bi-
parting installation
W A R N I N G !
TO REDUCE THE RISK OF DAMAGE DUE TO LIGHTNING,
ENSURE A SOLID GROUND FROM THE LPX1000
GROUND WIRE IN THE SERVICE ENTRANCE 4 x 4
HANDY BOX TO THE ELECTRICAL SERVICE GROUND
OR TO A EARTH GROUND STAKE NEAR THE LPX1000.
IMPROPER WIRING COULD CAUSE ELECTROCUTION
OR DAMAGE TO CIRCUITRY. FOLLOW LOCAL
BUILDING AND ELECTRICAL CODES.
