Now place another rack section end next to the end of
the rack just installed. Be sure that the two sections are
aligned and level and that the teeth match perfectly.
(Use another piece of rack, upside down, to check and
set the alignment of the teeth.)
Repeat the process of spot welding the spacers of this
rack section as you did on the first section. Continue
this process for each section of rack.
Final Welding: After spot welding all rack sections,
move the gate from the fully closed to the fully open
position several times. Make sure that the rack runs
smoothly along the center of the pinion. If the rack and
pinion operate smoothly, finish welding the spacers to
the gate.
Again, ensure smooth gate movement and then securely
tighten the rack mounting bolts in the spacers.

Remove the spot welds and shims from under the
mounting brackets. Secure the operator to the
foundation plate by welding the operator mounting
brackets to the plate.
Connecting the Control
Panel to Power and an
Activating Device
Note: Be sure to ground the gate and operator
system and protect the entire gate system with a
main power breaker switch (see Figure 10). Refer
to your local electrical codes and ensure they are
met when selecting these components.
Caution: The vent screw must be removed before
you start the operator (see Figure 1).
Connecting the control panel to your power supply and
accessories consists of the following general steps:
•
Connecting the control panel to main power
and to an activating device
•
Setting the limit switch controls for your gate
configuration
•
Checking the motor’s direction of rotation (for
the 844 B/C control panel only)
•
Adjusting the braking
•
Connecting other devices
•
Adjusting the clutch torque
•
Setting the DIP switches
