Repetition counter

Repetition counters are available for different types of errors. They are used to set the
number of errors permitted until lockout occurs. The last error initiates lockout. When
setting the number of errors to 3, for example, a repetition (restart) takes place after the
first 3 errors, and after the third error, the LMV37.4 initiates lockout.
Note
Setting 16 means an infinite number of repetitions = no lockout.
