Installation and Start-up Guide
Under normal circumstances, COV Throttling should be enabled to prevent
excessive network traffic if an object's COV Increment is set too low. See
EXCEPTION below.
When enabled, if an object generates excessive COV broadcasts (5 updates in 3
seconds), the driver automatically throttles the broadcasts to 1 per second. Also,
if the object's value updates excessively for 30 seconds, an alarm is sent to the i-
Vu® application listing all objects that are updating excessively. A Return-to-
normal alarm is sent only after all objects have stopped updating excessively.
EXCEPTION: In rare circumstances, such as process control, a subscribing object
may require COV updates more frequently than once per second. For these
situations, clear this checkbox, but make sure that your network can support the
increased traffic. You will also need to disable the Excessive COV alarms under
the driver's Common Alarms.
For values that change infrequently, select to verify at midnight daily that the
point is still able to communicate trend values.
You can unlock a controller for 24 hours to make IP address changes.
Click the Blink button to prompt the Locator LED to flash for 15 seconds, allowing
you to verify the controller's physical location. After flashing, whenever the
actuator moves, the LED rotates in the same direction. LED rotation is
automatically disabled after 1 hour and can be re-enabled by pressing the Blink
button again.
Enable only if directed by Carrier Control Systems Support.
