It must be selected by the complete operator model, installed wiring and board generation. Older CSL24V and CSW24V equipment requires the documented conversion procedure rather than a simple board swap. For paired gates, the bulletin also requires matching board versions across both operators, making the companion gate part of the purchasing decision.\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\u003eCSL24VDC \/ CSW24VDC\u003c\/td\u003e\n\u003ctd\u003eConfirm the installed revision and service instructions for this board.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSL24V \/ CSW24V\u003c\/td\u003e\n\u003ctd\u003eNot a direct out-of-box substitution; follow the manufacturer’s conversion bulletin.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eK1D6597-1CC \/ K1D6686CC\u003c\/td\u003e\n\u003ctd\u003eOlder main and expansion references must not be fitted to the newer VDC operators described in the bulletin.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDual-gate installations\u003c\/td\u003e\n\u003ctd\u003eBoth operators require matching main and expansion board versions.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLater U \/ UL models\u003c\/td\u003e\n\u003ctd\u003eNo automatic interchangeability with K1D8389-1CC or other later controls is established.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eCheck Both the Board Generation and the Wiring\u003c\/h2\u003e\u003cp\u003eA replacement board cannot be selected from the enclosure shape or a shortened model name.

This is qualified service work, not a general instruction to reverse connectors. Boards supplied after the bulletin’s stated October 2015 change also require monitored safety sensing.
