4.
Using the remaining crimp-on wire nut, attach the 10" black wire
with the .25" piggy-back quick-connect to the remaining black wire
coming from the counter.
5.
Locate the mounting position for the counter (Figure 1). Use the #8
screws (2) to mount the counter in the electrical box making sure
that the wires are not pinched under the counter.
6.
Locate the limit switch, plastic standoff for the limit switch, lock
washers (2), metal nut plate (1), metal back plate (1), and pan head
4-40 screws (2). Install the limit switch above the open limit switch
(OLS) in the operator (Figure 1). Be careful to line up the limit switch
with the OLS so that it will activate just before the OLS activates.
WIRING
Refer to the wiring diagrams provided with the operator. Should you need
a replacement diagram or you are unsure of wiring requirements, please
call Technical Service at (800) 528-2806.
1.
Connect the 10" black wire with the .187" quick-connect (attached to
the counter) to the common terminal of the limit switch that was just
installed (Figure 4).
2.
Connect the 10" blue wire with the .187" quick-connect and .25"
piggy-back quick-connect to the normally closed (NC) terminal of the
limit switch that was just installed.
3.
Remove both wires from the 24 Vac secondary of the transformer,
one yellow and one blue.
4.
Attach the .25" quick-connect of the blue wire (connected to the NC
terminal of the limit switch) to one of the bare terminals on the 24
Vac secondary of the transformer. Connect the blue wire removed in
the previous step to the piggy-back terminal of the wire.
5.
Attach the .25" quick-connect of the black wire (connected to the
counter) to the remaining bare terminal on the 24 Vac secondary of
the transformer. Connect the yellow wire previously removed from
the transformer to the piggy-back terminal of the wire.
6.
Secure loose wires with cable ties.
7.
Restore power to the operator. Verify normal operation.

Using the crimp-on wire nuts, attach each of the 20" black wires to
each of the black wires coming from the counter.
4.
Using the #8 screws (2), mount the counter to the electrical box
(Figure 5). Depending on the electrical box, it may be necessary to
drill one or more holes in the box to mount the counter securely.
Make sure that the wires are not pinched under the counter.
5.
Connect one of the black wires from the counter to the A1 terminal
of the close side of the contactor (Figure 4).
6.
Connect the remaining black wire from the counter to the A2
terminal of the close side of the contactor.
