The DRA Injector Control window is used to make minor operational changes to the DRA records.
Your Administrator has the ability to inhibit the control that you have over the following settings:
-
Entering a value for the DRA Concentration
-
Inhibiting the monitoring of Product Transfer Checking (Inhibit Violation Check)
-
Disabling the Injector (Disable Injector)
The permissions for each of these features are assigned separately, so depending on the nature of your responsibilities, you may be able to enter a value for the DRA Concentration, but not be able to Disable Injector.

Description |
|---|---|
|
State |
The DRAInjector record can be in the following states:
|
|
DRA Fluid Type |
Indicates whether the DRA injector is expected to use light or heavy DRA fluid. |
|
Rate Management Method |
Displays whether the rate is not managed (None), Calculated, or determined by Setpoint Lookup. |
|
DRA Concentration (ppm) |
Type an appropriate value for DRA concentration. If your Administrator has enabled the functionality, it is possible to type a value between 1 and 1,000,000 parts per million (ppm). |
|
Inhibit Violation Check |
Inhibits the violation checking of the DRAInjector record. If selected, the DRAInjector record will not be monitored for potentially problematic conditions. If the Administrator has inhibited the monitoring of violation checking, you will not be able to inhibit the violation check until you are given the permission to do so by the Administrator. Inhibiting the violation check also bypasses the Rules Validation Engine (RVE) rule checking. |
|
Disable Injector |
Disables the injector. If you select this checkbox, you are prevented from starting the injector. If selected by the Administrator, you will be prevented from enabling the injector. |
|
Injector |
Opens the Status/Multistate/Pump Control dialogs. If the injector is enabled, it will be possible to use the Status/Multistate/Pump Control dialogs to inject DRA. If the injector has been disabled, and the status, multistate, or pump point is started or stopped, an error message will appear to indicate that the injector has been disabled, either by you or the Administrator. |
|
Batch Transfer(s) |
Opens a small summary showing the Batch Transfers configured to provide product to this injector. |
|
Flush Point |
Opens a screen detailing the DRA Injector Flush Point. |
