Problem - Pendant Link Failure

[Heinster]

We posted a few weeks ago regarding some general problems with the Arrow 1000 having some random and untraceable issues with stability. We cleaned all the boards in the PC and the system is now very stable. However, we are still encountering a primary pendant link failure every so often, usually when the pendant is being handled.

Any thoughts as to what the issue could be?

Thanks.

hello my experiences would suggest that you have a connection problem with the pendant. i would suggest seperating the pendant face plate from the black body of the pendant ( remove the six screws and pull it apart ) and checking the internal connections. it is possible that you have a damaged case and that the damage is allowing the pendant to flex and causing the primary pendant link fail. if there is no damage and no loose internal connections then you are left with no other option than to change the pendant

Ditto on mallardfizz's recommendation! I've had this same problem for 2 years or more now, and have gotten that same diagnosis from many sources. As of yet it hasn't stopped me, it just takes a while to get the machine started (when I do shut it off, which isn't very often...).

The rebuilt pendant is over $2500 as I recall, so we're holding out until we have no choice (not my decision).

Rgds,

I just started having this problem last night and think it may be in the cable between the pendant and the monitor.
