Waiting time
The WAIT command is used for setting a particular waiting time or for
waiting until a particular time (run time) in a run sequence.
If pause is selected then the method run will be interrupted for the en-
tered duration (in seconds).
If runtime is selected then the method run will be interrupted until the
selected running time (seconds counter) has been reached. The run-
ning time (in seconds) always starts at the beginning of an individual
sequence, i.e. start sequence, sample sequence or final sequence. If
the running time of the sequence has already been reached or exceed
when the WAIT command is executed then the method will be contin-
ued immediately.

Initialize rack
The rack turns to the starting position, i.e. the lift (or both lifts) move
upward to the rest position and the rack is rotated to the initial position.
The rack code is read off and the SAMPLE variable (position of the cur-
rent sample) reset to 1. The RACK command should only be used in a
final sequence.
