DESCRIPTION

DUAL LIMIT SWITCH ASSEMBLY TIE WRAP, 5-1/2” SCREW, #4-40 X 1-1/2” LONG PAN HD PHILLIPS

3/16” BLACK SHRINK TUBING WIRE, 16GA. BLUE 5” STRIP X STRIP WIRE, 16 GA. WHITE 5” STRIP X STRIP

INSTALLATION INSTRUCTIONS

1. Unplug the eight pin connector (white) from the circuit board. Carefully remove the board from the four stands and let it hang to one side by the remaining wires.

2. Disconnect the yellow transformer wire from the eight pin connector by pressing the locking tab and pulling the wire out.

3. There are three yellow wires in a wire nut, one of these wires comes from the eight pin connector. Disconnect these wires from the wire nut. At this point the eight pin connector is only connected to the limits, this will allow the complete limit switch assembly to be removed.

4. Remove all four screws that hold the limit switches in place and return these screws to stock. Remove the complete limit switch assembly: if necessary, cut any wire ties that prevent the assembly from being removed.

5. The bottom limit switches (white switches) are the close and open limit switches, these switches will not be changed. Unsolder the wires from the top limit switches (red/black switches), these are the auxiliary limit switches,. as follows:

a. Locate the wire that runs from the common on the

close switch to the common on the auxiliary close switch, unsolder the end connected to the auxiliary closed switch.

b. Unsolder the yellow wire from the common on the

auxiliary close switch to the common on the auxiliary

open switch and set of to the side.

c. Unsolder the end of the orange wire that runs

to the normally closed on the auxiliary open switch.

d. Unsolder the end of the purple/white wire from the

normally closed on the auxiliary close switch.

WARNING

Disconnect power to the operator(s) before proceeding with installation.

6. If the two auxiliary limit switches are not damaged return them to stock. Install the two new dual switches in place of the original auxiliary switches. If a fixture is not available it may be necessary to connect the switches together to hold everything steady for soldering. It might be easier to solder some wires on before putting everything together. It will be necessary to have everything together to resolder the yellow wires removed in step 5.

7. Please see figure 1 for the arrangement of the wires. Remember to install shrink wrap tubing on all of the wires on the normally closed (NC) and normally open (NO) prongs of the switches. It is not necessary to insulate the wires on the common (C) prongs.

9. Install the switch assembly back in the operator. Replace any wire ties that had to be cut to remove the original assembly. Reconnect the three yellow wires into the wire nut. Reinstall the yellow transformer wire into the eight position connector (see figure 2 for the exact location) between the orange/black and the yellow wires.

10) Reinstall the circuit board and plug the eight position connector back onto the board.

11) Run the operator and check continuity on the new switches. Coil up the blue and white wires so the cover can go back on. Supply diagram 04145.
