electrical service depends on the distance of the operator from the
breaker panel. Refer to Table 1 to determine the correct wire size.
The NOMINAL column is the ideal distance from the breaker panel
to the operator for a given wire size and voltage. The distances
shown in the MAXIMUM column should never be exceeded and
should only be used where it is known that the voltage at the power
panel will never be less than 105 VAC. (The HDSWG 1000 will
operate at a voltage as low as 95 VAC measured at the input
terminals to the operator. The "maximum distance" of Table 1 is
calculated to supply 95 VOLTS to the HDSWG 1000 during the
"stop cycle" when the line voltage is at 105 VOLTS.) NOTE! FOR
A BI-PARTING INSTALLATION, THERE WILL BE TWO
MECHANICAL UNITS OPERATING AT THE SAME TIME.
IT WILL BE NECESSARY TO REDUCE THE LENGTHS IN
TABLE 1 BY A FACTOR OF TWO.
Class 2 low voltage wiring from external controls such as a key pad,
card reader, telephone entry device, etc. must be brought to the
HDSWG 1000 CONTROL BOX by a separate conduit from the 115
VAC electrical hook up conduit. Low voltage control wires MUST
NEVER be routed in the same conduit as the HIGH VOLTAGE
power wires.
Note! The limit switch wires from the HDSWG 1000
CONTROL BOX to the HDSWG 1000 MECHANICAL
UNIT ARE LOW VOLTAGE WIRES AND MUST BE
ROUTED IN A LOW VOLTAGE CONDUIT TO THE
CONTROL BOX.
OTHER VOLTAGES AND THREE PHASE SYSTEMS.
The HDSWG 1000 can operate at other voltages or on three (3)
phase systems. To operate at 440 VAC it will be necessary to install
an external step down transformer. The transformer should be
located in a separate electrical box and protected by suitable circuit
breaker and/or fusing. A 440 Volt rated switch should also be
installed. Follow local electrical codes or the National Electrical
Code. The transformer selected should be UL LISTED and be rated
for 500 Volt-Amperes/Watt.
IF TWO MECHANICAL UNITS ARE TO BE USED FOR A BI-
PARTING GATE SYSTEM, THEN A 1000 VOLT-AMPERE/
WATT TRANSFORMER MUST BE USED.
Operating from a three (3) phase line will require the use of a 230
VAC rated HDSWG 1000. The HDSWG 1000 may be operated from
a 230 Volt "Delta" line or a 120/208 "Y" line. In either case, ONLY
one "leg" of the three phase line will be used. The unbalance of the
line will be minimal since the full rate current of the HDSWG 1000
at 220 VAC is only 2.2 amperes. (4.4 Amperes for a bi-parting
system.) Connect any two wires of the three phase system to the 230
VAC HDSWG 1000 Tape the third wire carefully so that it does not
short to any other object. (The "Y" system will have 4 wires, one of
which will be the "common". Make sure the common is NOT
selected as one of the wires connected to the HDSWG 1000.) It is
always best to also pull a ground wire from the electrical service box
to the HDSWG 1000 to ensure the frame is securely affixed to
GROUND.
SERVICE CONDUIT
For new installations the conduit for the High Voltage may be
brought to a junction box near where the HDSWG 1000 CONTROL
BOX will be located or it may be brought directly to the Control
Box.
WARNING!
AVOID ELECTROCUTION:
DO NOT ROUTE LOW VOLTAGE WIRES IN SAME
CONDUIT AS HIGH VOLTAGE WIRES. FOLLOW
ALL LOCAL ELECTRICAL CODES OR THE
NATIONAL ELECTRICAL CODE.
