  • Off: Sets the Percent Cmd to 0% and sets the Instant Shutdown output to False. The MSC turns off all outputs, but only after all timers are satisfied.

  • Max: The Percent Cmd is set to 100%. This value then feeds through the MSC and the stages turn on accordingly based on the timer settings.

  • Limited Max: Set the output to the limited max value. This value then feeds through the MSC and the stages turn on accordingly based on the timer settings.

  • Hold: Hold the Percent Command output at it’s current value. This value continues to feed to the MSC and the stages continue to be controlled by the sequencer. Should timers expire, it is possible for the number of enabled stages to change during a hold command since the Percent Command is really the only value that is explicitly held.

  • Instant Shutdown: Sets the Percent Cmd to 0% and sets the Instant Shutdown output to True. The MSC turn off all outputs instantly.

  • Control: Adjust the output to control the Process Variable. As this Percent Cmd varies, it causes changes to the enabling of the staged outputs from the MSC.

  • Failsoft: Set the output to the Failsoft value. This value then feeds through the MSC and the stages turn on accordingly based on the timer settings.
