LEFT- OR RIGHT-HAND INSTALLATIONS
The Tower operator can be configured for left-hand gate installations.
See Figure 15. On a normal drive installation, when standing inside the
gate and facing outwards, if the operator is on the right side of the gate,
it's a right-hand installation. If the operator is on the left side of the
gate, it's a left-hand installation.
The operator is shipped from the factory configured for right-hand
installations. If it is installed in a left-hand installation, it will be
necessary to reconfigure the limit harness and high voltage harness
wiring to left-hand operation. The conversion technique is a two step
process.
LEFT-HAND CONVERSION - STEP 1
Locate the limit harness where it attaches to the motor control
board as shown in Figure 16. As shipped from the factory the
harness is connected to the control board by its
"IN-LINE"
connector. To reconfigure the limit harness for left hand operation
remove the harness
"IN- LINE"
connector from the control board
and reconnect the harness to the control board utilizing the
"END"
connector. The limit harness is now configured for left-hand
operation, continue and complete Step 2.
LEFT-HAND CONVERSION - STEP 2
Locate the capacitor wire connections as shown in Figure 16. On
one capacitor terminal post there is a
RED
wire from the motor
and a
RED
wire from the high voltage wire harness and on the
other capacitor terminal post there is a
BLUE
wire from the motor
and a
BLUE
wire from the high voltage wire harness. Trace and
identify the
RED
and
BLUE
wires which originate at the motor.
SWITCH THESE WIRES
such that the
RED
motor wire is on the
capacitor terminal post with the
BLUE
wire from the high voltage
wire harness
AND
the
BLUE
motor wire is on the capacitor
terminal post with the
RED
wire from the high voltage wire
harness. The high voltage wire harness is now configured for left-
hand operation. Left-hand conversion is now complete.
MOUNTING THE LIMIT CAMS
Before turning on the main power, the limit cams must be mounted
to the chain in their approximate positions. See Figures 17 and 18.
Figure 17 illustrates a view of the Tower Control Box / Mechanical
Unit that faces the gate which depicts the Output Drive Sprocket
and the Sensing Mechanism components.
Figure 18 shows how to install the Limit Cams to the chain.
NOTE: IT IS IMPORTANT TO INSTALL THE CAMS
AROUND THE WHOLE LINK AS ILLUSTRATED AND
WITH THE STUD/NUT IN THE PROPER ORIENTATION AS
OUTLINED IN THE FOLLOWING PARAGRAPHS.
Manually push the gate all the way open. As depicted in Figure 17
locate and mark with chalk the proper chain link (depending on
Right-Hand or Left-Hand operation) for
OPEN
Limit operation.
Manually push the gate all the way close. Following the procedure
shown in Figure 18, mount the Limit Cam on the chain link that
was marked with chalk in the previous step, the link should now be
parallel with the ground and approximately 4 to 5 feet from the
end of the gate. The cam
MUST BE
mounted such that the lobe is
DOWN (TOWARD THE GROUND).
NOTE: IF RIGHT-HAND OPERATION (STANDARD)
MOUNT THE CAM WITH THE STUD/NUT POINTING AT
THE GATE, IF LEFT-HAND OPERATION MOUNT THE
CAM WITH THE STUD/NUT POINTING AWAY FROM THE
GATE.
As depicted in Figure 17 locate and mark with chalk the proper
chain link (depending on Right-Hand or Left-Hand operation) for
CLOSE
Limit operation.
At this time recheck the Toggle Limit Switch
ACTUATORS
for
proper positioning to accept the limit cams. See Figure 17.
Manually push the gate all the way open again. Following the
procedure shown in Figure 18, mount the Limit Cam on the chain
link that was marked with chalk in the previous step, the link
should now be parallel with the ground and approximately 4 to 5
feet from the end of the gate. The cam
MUST BE
mounted such
that the lobe is
DOWN (TOWARD THE GROUND).
NOTE: IF RIGHT-HAND OPERATION (STANDARD)
MOUNT THE CAM WITH THE STUD/NUT POINTING
AWAY FROM THE GATE, IF LEFT-HAND OPERATION
MOUNT THE CAM WITH THE STUD/NUT POINTING AT
THE GATE.
