The table below lists the commands supported by the Interlock.
Command Name |
Parameters |
Description |
---|---|---|
Disable |
None |
Locks out all outputs and prevents the Interlock functionality. |
Enable |
None |
Ensures object reacts to any changes it may have missed while it was disabled, and returns it to normal operation. |
Operator Override |
The value to be written to the Present Value attribute. This parameter has a True or False data type. |
Updates the Present Value at Command Priority Operator Override.
Important: The Operator Override command sends the specified command to the internal NxE object, which is then only sent to the field device when one of the following conditions is met: a) NOT Local Control and NOT Out Of Service, or b) NOT Local Control and after issuing the In Service command.
|
Release Operator Override |
None |
Releases Command Priority Operator Override from Present Value. |
Re-command |
None |
Reissues the commands for the current state. |
Release |
Attribute name Command priority |
Releases the identified command priority from the specified, writable attribute, and allows it to be controlled by the next highest priority. |
Release All |
Attribute name |
The Release All command releases priorities from 3 to 5
and from 7 to 16. The Release All command does not affect
priorities 1, 2, and 6, which are reserved for Manual Life
Safety (priority 1), Auto Life Safety (priority 2), and Minimum
On Off control (priority 6).
Note: The Release All command
may not cause an immediate return to automatic operation. The
Release All command clears all command priorities, including
those that come from applications and features. When this
happens, the output point goes to its Relinquish Default
condition. In some cases, the application or feature may have
sent a command that does not match Relinquish Default. In this
instance, the output point does not end in the state that the
applications or features intended. This situation can cause
unexpected operation to occur; for example, a space could
overcool or overheat, a fan might run longer than expected, and
so on. If an operator has overridden an input, use the Release
Operator Override command.
