PRODUCT NOTICE Page 3 of 6 expanding human possibility™ – Description – PVLV – Incorrect operation when controller transitions from Program to Run. Output to device is incorrectly generated when the controller is transitioned from Program to Run status. Expected behavior is that the PVLV function should not produce any output when the valve is at rest in the selected position unless there is an operator or program command to do so. This anomaly can specifically cause equipment damage when applying the PVLV instruction to motorized valves. – Temporary Workarounds – The workaround is to apply external logic (as shown below) to disable any errant signal from the PVLV instruction being propagated to the field.
