Limit value of OT

The value of the operating hours in OT are retained when
you reset the hours counter with a signal at input R. The
hours counter OT continues the count as long as En = 1,
irrespective of the status at the reset input R.
The counter limit of OT is 99999 h.
The hours counter stops when it reaches this value.
In programming mode, you can set the initial value of OT.
The counter starts operation at any value other than zero.
MN is automatically calculated at the START, based on the
MI and OT values
(Example: MI = 100, OT = 130, the result is MN = 70).
