5.7.5 Hold Active
If Hold Active is enabled in Auto cycling Setup, then the values remain in the hold state
during auto cycle. When Hold is active on either input, the status message “Hold Active”
is displayed and the specific PV value flashes at a very slow rate.
When Hold is activated manually from the front panel Hold button, the values remain in
the hold state until its state is changed via the front panel again.
5.7.6 Probe Transit
This parameter is available to allow you to automate functions that relate to probe
removal and insertion. Once the probe transit parameter is enabled, the extract wait
source, insert wait source and max transit mins can be selected. The extract wait source
and insert wait source can be set to any digital input so that the extract or insert
operations continue until the selected digital input is low. Once the wait source signal is
low then the probe extraction or insertion sequence step can end or otherwise time out if
the duration of the “max transit mins” is exceeded. If probe transit is enabled and probe
extract src/insert src is set to none, then the probe extract/insert step will occur for the
duration of the max transit mins.
5.7.7 Cycle Start Src
The Auto cycle can be started in one of three ways. It can start upon the occurrence of a
specific digital input changing state from low to high. The cycle can also start when the
cycle timer engages. The cycle can also be manually started from the Auto Cycle display
screen op panel.
5.7.8 Cycle Interval
This parameter enables the cycle timer and allows you to set the Auto cycle to recur at a
period defined by you. If the cycle interval is set to Custom, Monthly, Weekly or Daily
then specific menu items are activated to set-up cycle start and period times. You can
select a cycle interval appropriate to the application.
5.7.9 Rinse Cycle Cnt
This parameter allows you to select when or if a rinse sequence occurs during a cycle. A
selection of 0 indicates that a rinse sequence will not occur. A selection of 1 indicates
that a rinse sequence occurs during every cycle. There is an option to set the rinse
sequence for less frequent times by selecting values from 2 to 100. For example; a
selection of 3 means that the rinse sequence will occur every 3rd cycle.
5.7.10 Rinse Mins
This parameter allows you to select the duration of a rinse.
5.7.11 Resume Dly Mins
This parameter allows you to specify a delay time before the cycle is completed.
