I’ve got a Tac20 with HD98 door operator, and it appears to be deteriorating in terms of slowing the door down at final open and close. Door bangs shut with no final slow down and slam dunks into a harsh transition to open slow in the last couple inches before full open. Open slow transition is harsh enough to de-clutch the hall door at times. Naturally, no User Interface Tool on the controller or door operator.
Can one add the factory UIT to the controller and operator?
I’m not sure whether to suspect the main board in the operator or the module on the end of the Door Op motor as a potential problem. Any experienced input?
I need to get an HD98 manual and see if there are any checks I can do in the absence of the UIT.
Thanks!

You know, I haven’t watched it for Belt slipping. That’s a good idea to check. I appreciate the tip.

I have found that linkage bolt loose on other jobs, will definitely check that!

Went back yesterday and it only did it a couple times in the open direction in 30 minutes of running it. Yesterday was a cold day here, and cool in the hoistway.
The previous visit it exhibited the problem at both floors, open and close, and about 97% of the time - and it was a hot day and hot in the hoistway. Seems like there may be a temperature sensitivity, there..
Belts weren’t slipping, linkage right, brushes show hardly any wear. I’ll keep an eye on it.

For the doors coming uncoupled, I’ve had really good luck replacing or even doubling up the spring steel plates in those old clutches.
