Honeywell UDA2182 Hold Active, Probe Transit, Cycle Start Src, Cycle Interval, Rinse Cycle Cnt

Operating the Analyzer

5.7.5Hold 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.

5.7.6Probe 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.

5.7.7Cycle 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.

5.7.8Cycle 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.

5.7.9Rinse 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.

5.7.10Rinse Mins

This parameter allows you to select the duration of a rinse.

5.7.11Resume Dly Mins

This parameter allows you to specify a delay time before the cycle is completed.
