Installation Guide for the 1768-KY1
Only a trained professional should install this replacement key. Begin by powering down the entire CompactLogix controller system. Locate the existing key on the front panel of your 1768-L43 or 1768-L45 controller. Remove the worn or damaged key by pulling it straight out from its socket. Align the new 1768-KY1 key with the same orientation as the original part. Push the key firmly into the socket until it clicks into place. Rotate the key gently to verify it moves through all mode positions smoothly. Power the controller back on and test each mode setting. The controller uses the pre-configured settings from the initial installation. You do not need to reconfigure the controller software for this key replacement. Verify the output power matches the requirements of your attached motor. Check that the controller responds correctly to each mode selection. Document the replacement in your maintenance log for future reference.
