Helping Hand?
With built in redundancy, these libraries are very robust. A common misconception
is that both Hands work concurrently, but in fact only one Hand at a time
is used and then one is dedicated to mounts while the other performs CAP
(Cartridge Access Port) and CEM (Cartridge Exchange Mechanism) requests.
When a Hand becomes inoperative, all movements are carried out by the remaining
Hand with no loss of performance.
IPLing an LSM causes all of the the robotic assemblies to recalibrate. Any inoperative status is reset during this time allowing mechanisms flagged as inoperative to be returned to service upon successful completion.
If a Hand & Camera assembly repeatedly goes inoperative due to targeting errors despite being replaced, likely culprits are a worn Z-belt or pulley assembly. These worn parts will allow the Z-assembly to recalibrate, but will distort its map of the library by a small amount (depending on the amount of wear) and later cause positioning problems. During operation the Hand will encounter targeting problems due to the Z-assembly being slightly out of position, and will go inoperative once the retry threshold has been reached. An IPL will reset the Hand status to operational status again but the problem will recur until the Z-assembly is repaired. If in doubt, the 'soft logging' option can be used to record all robotic activity and give a much clearer view of the problem. This feature should only be used for a short time as it will very quickly wrap the log with valueless routine information.
Remote Support
Level 1 technical support functions are available including remote equipment
monitoring and support, subject to certain conditions (refer to the 'Terms
and Conditions' section under the 'Home' menu). With this option the performance
of the equipment can be routinely monitored and the relevant personnel made
aware of any issues that will cause degradation.
Online Support
If no remote connection to the equipment exists when a problem occurs,
any error information can be emailed for analysis instead. A full recovery
plan will be formulated and sent to the required personnel, along with details
of any necessary parts and procedures needed to ensure that equipment downtime
is kept to a minimum.
