It is intended for a diagnosed control-board replacement in a compatible system. The supplier identifies this service part for applicable operators manufactured after 2016. Documented application examples include the CSL24U slide-gate and CSW24U swing-gate systems, subject to the correct production revision and approved service replacement. Before ordering, identify the installed board and control configuration so the repair addresses the diagnosed fault and preserves the required safety-device functions.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eCompatibility — Models, Versions and Exclusions\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel or selection point\u003c\/th\u003e\n\u003cth\u003eCompatibility requirement\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSL24U slide-gate system\u003c\/td\u003e\n\u003ctd\u003eK1D8389-1CC appears in the repair-parts documentation; verify the installed revision and approved MC service replacement.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSW24U swing-gate system\u003c\/td\u003e\n\u003ctd\u003eThe manual identifies K1D8389-1CC; match the production date and existing control-board label.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLA400 \/ LA500 linear-actuator systems\u003c\/td\u003e\n\u003ctd\u003eDo not substitute this pad-mount board for the K1D8388 linear-actuator board.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther or older operators\u003c\/td\u003e\n\u003ctd\u003eNo universal retrofit is promised.

Supply problems, damaged field wiring, an actuator or motor fault, and a safety-device fault can produce similar symptoms. Replacing the board without identifying the cause can leave the original problem unresolved. A technician should use the operator diagnostics and inspect the connected circuits before selecting this service part.\u003c\/p\u003e\u003cp\u003eThe printed board reference, service-kit order number and operator model serve different purposes. Photograph all three where available. If the housing has been retained through an earlier electronic upgrade, its exterior label alone may not describe the controls now installed.
