The following diagram shows the timed response of the Deadtime function block in Auto mode:
You select the way the input signal is processed with parameter configuration and input wiring.
Delay value and status
The time delay to be introduced to the IN input is normally determined by the DEAD_TIME parameter. You enter the value of DEAD_TIME (in seconds), or another function block connected to IN can perform a calculation and enter the value automatically.
When the FOLLOW input parameter is active (True), no delay is introduced and the delayed input values stored by the block are initialized to the IN value and status.
Balance output
In Man mode, the OUT value of the block can be entered manually. Thus, the delayed input value might not match the current block output. To avoid bumping the output on a mode change from Man to Auto, a bias value is added to the delayed signal so the resulting value matches the OUT value.
In Auto mode, the delayed input plus the bias is the value of the OUT parameter. The bias value added during the transition from Man to Auto mode is ramped from the OUT value calculation over the time defined by BAL_TIME.
