Appendix B
Trouble-Shooting and Maintenance
There are no user-serviceable parts or user adjustments to be made to the
ESP6000 controller card or UniDrive6000. Fuse replacement procedures
for the UniDrive are provided in this section.
WARNING
Procedures are to be performed only by qualified service personnel.
Qualified service personnel should be aware of the shock hazards
involved when instrument covers are removed and should observe
the following precautions before proceeding.
– Turn off power switch and unplug the unit from its power source;
– Disconnect cables if their function is not understood;
– Remove jewelry from hands and wrist;
– Expect hazardous voltages to be present in any unknown circuits.
WARNING
Fuse replacement involves removing an enclosure panel which
can expose you to terminals having hazardous voltages in excess of
250 VAC at various locations.
CAUTION
Verify proper alignment before inserting cables into connectors.
Do not force.
Refer to Appendix G, Factory Service, for information about repair or other
hardware corrective action.
B.1 Trouble-Shooting Guide
Most of the time, a blown fuse or an error reported by the ESP6000 con-
troller card is the result of a more serious problem. Fixing the problem
should include not only correcting the effect (blown fuse, limit switch,
etc.) but also the cause of the failure. Analyze the problem carefully to
avoid repetition. A list of the most common problems and their corrective
actions is provided in Table B.1-1. Use it as a reference but remember that
a perceived error is usually an operator error or has some other simple
solution.
