"H-O-A" (HAND-OFF-AUTO) SCREEN
These H-O-A buttons force the selected component to be energized
(HAND), de-energized (OFF), or automatically energized by the
normal logic sequence (AUTO). The HAND function will cause the
component to operate independent of whatever else the system is
trying to do automatically. These functions should not normally be
used if the automated sequencing is active. Be sure to
understand the impact of energizing or de-energizing a
component with the HAND/OFF settings before using them.
These commands are not a substitute for Lockout/Tagout
procedures when working on or near this machine. Use proper
lockout/tagout procedures to disable the equipment before
servicing it.
