5.7.12 Manual Starting/Stopping the Auto Cycle
Pressing Enter on the Auto Cycle Operational Display brings up an operator panel menu
that enables you to manually start or stop an auto cycle sequence or place the cycle in
Hold, regardless of whether or not the cycle timer is configured. Start cycle is visible
when the Auto Cycle is not active and Stop Cycle is visible during an auto cycle.
The objective of a Cycle Stop is to terminate the Auto Cycle by putting the probe back
into the process. The selection of Cycle Stop causes the sequencer to proceed directly to
the Probe Insert stage, if Probe Transit is enabled, and then to the Resume Delay stage.
Selecting Stop Cycle during Probe Insert advances the sequencer to resume delay.
Finally, a Stop Cycle selection during Resume Delay will stop the cycle completely.
If enabled, the cycle timer will still trigger a cycle at the configured time provided the
sequencer returns to Cycle Stop beforehand. Otherwise, the cycle will execute at the next
available time.
The Hold Cycle selection is available in both auto cycle active and inactive states. When
inactive, enabling Hold Cycle will hold the sequencer at the beginning of the sequence
until released to continue by disabling the Hold Cycle.
Selecting Hold Cycle during an active cycle will suspend the sequencer at the current
step as well as the step timer. Disabling Hold Cycle will resume the sequencer and step
timer. During cycle Hold, the status bar will show the message “Auto Cycle in hold”.
