NOTE: Before running power wiring refer to wiring specifications
on page 14 for correct wire gauges.
Secure all electrical power connections inside the disconnect
switch electrical box. Refer to electrical wiring diagram on pages
33 and 34.
Important: On three phase operators, power connections must
be properly phased. If phased incorrectly, the gate operator will
run backwards. To correct this situation, shut off power at main
power source and at the operator's electrical disconnect switch.
Then reverse any two of the three power leads.
SINGLE PHASE
All single phase operators will have the following:
115V
" L1 (NEUTRAL), WHITE
" L2 (HOT), BLACK
" GROUND, GREEN

1. This control will function as a Stop/Reset command and is to
be wired within line of sight of the gate. The operator will not
function unless this circuit is completed.
2. Wire Stop/Reset control station to terminals 3 and 5 in the
control box on the operator.
TERMINAL BLOCK
MAKE SURE THE LIMIT NUTS ARE POSITIONED BETWEEN THE LIMIT SWITCH ACTUATORS BEFORE PROCEEDING WITH ADJUSTMENTS.
1. By using the mechanical disconnect, manually open the gate to
its full open position.
2. Remove control panel cover and locate the rotary limit switch
assembly. Disengage the detent plate from the limit nuts, as
shown.
3. Depending on "hand" of the operator, rotate the open limit nut
until it makes contact with the open limit switch lever and trips
the open limit switch activation button.
4. Adjust the other limit nut so that it is near the open limit nut
but not touching.
5. Manually close the gate to its full closed position.
6. Disengage the detent plate and rotate the close limit nut until it
makes contact with the close limit switch lever and trips the
close switch.
7. Re-engage the detent plate into both limit nuts and also
re-engage the mechanical disconnect.
