If any operator is more than 2 ft away from the U.L.
Listed control panel enclosure, the connection must be
made inside a junction box. Use a U. L. Listed cord grip
where the operator cord enters the junction box; use
conduit between the junction box and the enclosure.
Connecting the Operator(s)
Caution
: Do not use the terminal connections
for Motor 2 (terminal 6, 7, and 8) if yours is a
one-leaf gate design.
Note
: If you have a one-leaf gate design, the
operator must be connected to Motor 1
(terminals 3, 4, and 5).
If your gate system has one operator, connect the
capacitor and the brown and black (or red and black)
wires from your operator to the terminals 3 and 5 in
block J2 for Motor 1. Connect the blue (or white) wire
from the operator to terminal 4 for Motor 1.
Note
: If you want to delay the closing of one
gate leaf in a two-leaf gate design, be sure to
connect its operator to Motor 1 (terminals 3, 4,
and 5).
If your gate system has two operators, connect the
second operator to terminals 6, 7, and 8 in block J2 for
Motor 2. Connect the capacitor and the brown and black
(or red and black) wires to terminals 6 and 8, and
connect the blue (or white) wire from the operator to
terminal 7 for Motor 2.
Check the Motor’s
Direction of Rotation
After you have connected the main power supply, one
activating device, and the operator(s) to the control
panel, you need to check the direction of rotation for
each operator motor in your gate design.
To check a motor’s direction of rotation, you must have
three closed circuits on terminal block J3. Install one
circuit between terminals 11 and 13, another circuit
between 13 and 21, and another circuit (or stop device)
between terminal 14 and 15.
You cannot check the motor’s direction of rotation
without these circuits (jumpers) or the accessories.
When properly prepared for testing, the LEDs DL2 and
DL3 should be illuminated.
WARNING!
Running the operator—even for
testing purposes—without a connected
reversing device is potentially dangerous. Do
not place yourself within the path of the
moving gate during your test.
Disengage the operator(s) with the Manual Release key,
and open the gate by hand about halfway.
Next, engage the operator(s) with the Manual Release
key so that you can check the rotation of the motor(s).
Turn on the main power and send an activating signal to
the operator. The gate leaf (or leaves) should open. If a
gate leaf closes, then you need to turn off the main
power and reverse the connection of the brown and
black (or red and black) wires on terminal block J2 for
the operator controlling that leaf. Then you need to
recheck the rotation direction again.
If your gate system has two operators, be sure the motor
of each rotates in the correct direction.
After having completed your test of the motor’s
direction of rotation, replace any test circuits you
installed (between terminals 11 and 13, between 13 and
21, and between 14 and 15) with the proper reversing
and stop devices. The instructions for installing such
accessories follow.
Connect Other Devices
WARNING
! Turn the main power off before
you make any electrical connections or set any
switches inside the control panel box.
Now you can connect additional reversing and activat-
ing devices to the control panel. Refer to Figure 13 for
the general control panel layout, and refer to Figure 14
for the layout of the terminal strip.
Note
: The 450 MPS control panel allows a
maximum accessory load of 500 mA.
Power Supply for Accessories
: You can access a 30
VDC output for supplying power to accessories that
require DC voltage through terminals 9 and 10 (located
above the label
30 Vcc
) on terminal block J3. In most
cases, this source can be used to power 24 VDC
accessories.
Reversing Devices
: Reversing devices include
photocells, inductive loops, and so forth. All of the
reversing devices should have contacts of the normally
closed (N.C.) type. Where you connect a device
depends on whether you want the device to operate
during opening or during closing.
Note
: A reversing device is required for a U.L.
recognized installation.
Caution
: Failure of a reversing device that
operates during opening causes a gate to lock
