Dover LHM or LMH : LUSENET : Elevator Problem Discussion : One Thread

Anyone know anything about these? Saw one for the first time. I'm wondering if it's just someone elses PLC with a dover sticker over it, kind of like the do with the "Dover" Nordic Starter? How do they run etc.? Looks like all of the IO are labeled. Looks like a straight forward unit to troubleshoot, but thought I'd check.

Thanks Dan

Hi There, I have worked on those beauties, They are IDEC FA2J PLC and they are used by many other elev control mfg for years. IDEC is a great company located in Japan and they have supported everything they ever made and their US headquarters are located in silicon valley and have free technical help and a 800 number. I have also been to a free 3 day programing class (begining, advanced, touch screens)there and they also have it in other states, the fee is $500 per day but can be waved by your local dist. TK sold these as a mod controler and also as a logic replacement for hydros and fire service. I always wondered who at TK did the field programing. All the manuals are on line for free and the sofware and cables are reasonable and software should be copied on job for backup. Jim
