8-7-2 XY Brake Assy replacement
8-7-2-1 Preparations
When preparing for the replacement, you must perform the following steps:
1.) Make sure the XY arms are in the unlocked (floating) position.
NOTE: While VIVID E9 is shutting down, make sure the XY arms are in the unlocked (floating) position
and hold the brake release/XY unlock button until VIVID E9 is fully shut down. This will remove
tension from the brake shoes and allow for much easier brake assembly removal.
2.) Power down the VIVID E9.
3.) Disconnect the Mains Power Cable from the wall outlet.
4.) Disconnect all probes and external I/O cabling.
