It collects the car top signals and communicates with the lift controller over the CAN bus. In the Otis documentation the TOCB is a car I\/O board of the Gen2 system, together with boards such as the COPG and the CSPB.<\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">Q2: What other names and part numbers is this board known by?<\/strong><\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">A:<\/strong>\u00a0The board is written FBA25402CL20, and it is also written FBA25402 CL20. It is best known as the TOCB board, which stands for Top Of Car Board, and it is also called the car top board, the car top main board, the car top PCB and the car top I\/O board. Please do not confuse the FBA prefix with the FAA prefix, because the two families are different.<\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">Q3: Which Otis lifts is the TOCB board used on?<\/strong><\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">A:<\/strong>\u00a0It is used on Otis Gen2 lifts, including the Gen2 MRL installation. The board sits in the car top box, so it is reached from the car top during maintenance. Please confirm the lift model, the controller type and the board version before ordering.<\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">Q4: What is the difference between the FBA25402CL20 and the other FBA25402 versions?<\/strong><\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">A:<\/strong>\u00a0The FBA25402 family contains several versions of the same car top board, and the version marking is part of the part number. Some versions are supplied without the option assembly, and some are supplied with the option assembly. The FBA25402CL30 is listed without the option assembly, and the FBA25402CD20 and the FBA25402CR40 are listed with it. Because the versions are not interchangeable in every installation, please compare the part number on your original board with ours before ordering.<\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">Q5: What does the option assembly version mean?<\/strong><\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">A:<\/strong>\u00a0The option assembly is the additional assembly fitted on the car top board for the newer lift safety standard. The EN81-20 version of the car top board is listed with the option assembly. If your lift is certified to the newer standard, please tell us the standard and the part number of the original board, and we will confirm the correct version for you.<\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">Q6: How can I confirm this board matches my lift, and do you supply other Otis car top parts?<\/strong><\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">A:<\/strong>\u00a0Please compare the part number on the label of the original board, the connector positions and the board layout with the photos we send you. If you are not sure, please send clear photos of the front and the back of the board, and our technical team can help identify the correct version. We also supply the other FBA25402 car top board versions, the FBA25402AJ1 junction box PCB, the Otis CSPB board and other Otis Gen2 control and car top parts.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Otis car top board FBA25402CL20 is the TOCB, the top of car board of the Otis lift, and it is fitted in the car top box.
