tach 20

looking at taking tach 20's on for maint. is there anything special about them or are they proprietary?

I would recommend a laptop with the IMS program. It makes troubleshooting a lot easier

Some of the Tac 20 mod products have a built in LCD display for troubleshooting.

You definitely need IMS software and from my own personal experience, you will at some point need the LONSTALK adapter. There are jobs that have the UIT (lcd unit) but the IMS is such a great tool to have for many other Thyssen products as well.

We can sell IMS software with unlimited license to you, for more information please contact me, HAMID2@GMAIL.COM

Where do you get ims tool

Most tac 20s dont have UIT or inspection switches in the controller. That would be the tac 22. Overall good running units. Also matters which door board you have. The 6300 Ge4 does not have a UIT but if it has the 6300 ABn1 then it has a UIT. If it does have the GE4 board you will need fast tool or door fast to set it up change parameters and do a door scan. The 6300abn1 boards do lose the door scan if you cut the power but with the UIT it takes a matter of seconds to do the scan. The tac 20 uses the 16 bit IMS. There are some 16 bit ims clones on the market. I believe we installed some units with the linear door operators on them but I dont have much on those. good luck

just keep some solid state starters handy.

That aint no lie my parts room I have like 4 or 5 laying around. I only have 4 of these units
