lcUpsControlOutputOnDelay
Liebert Ups Control Output On Delay
1.3.6.1.4.1.476.1.1.1.1.8.2
Setting this object causes the agent to instruct the UPS to turn on the output after the indicated number of seconds. The agent counts down the number of seconds until the event will take place. The agent issues an lcUpsOutputOnTrap when the countdown finishes. Note that different models have different clock resolutions, usually greater than 1 second. As a result, the command will only be accurate to the resolution of the UPS's clock. The command can be cancelled by setting lcUpsControlCancelCommand to the value cancel.
