I used to see this in a previous life, but when they replaced the stainless steel helix with a composite (carbon-teflon?) one, this problem disappeared. You may want to ask your SE. Steve Schaub Systems Engineer, WNI BlueCross BlueShield of Tennessee 423-752-6574 (desk) 423-785-7347 (cell)

The robotic actuator achieves vertical motion via a roughly 5' tall steel helix. The helix is lubricated with a grease. Over time, the grease dries out - and solidifies. The robot then strains to gain elevation, which over-taxes the vertical drive motor and causes an electrical Intervention Required. The associated panel message specifies an IBM service call. They will respond by cleaning and re- lubricating the shaft. To prevent an outage of some hours, you may want to assure that your CE is performing periodic re-lubrication of this assembly. One would think that it would be on the list of PM tasks, but apparently it is not. Other robotic library types may have a similar vulnerability.
