An aggregate is controlled via command output A…D ( ).
Normally, the command output sends the signal via the motor block to output
terminal Q(x).

You can set for all steps a common "Runup delay", "Locking time", and "Restart
time" for the command output.

This delay ensures that during run-up between the stages, the next step can be
switched on only after the set run-up delay. This ensures that e.g. a step of the
refrigeration machine is run up before the next stage of the refrigeration machine is
switched on.
Run-up delay
This ensures that a step that has just switched off remains off for the set period of
time. As a result, the compressor e.g. remains switched off for the set time.
Locking time
Ensures that the aggregate can restart after expiration of the set time. The time
begins from the moment the aggregate is switched on. This ensures, e.g. that the
heat pump restarts only after a set time.
