PARAMETER CHANGE WHILE TEMPORIZATION IS
IN PROGRESS
When a parameter in the programming cycles of the timer is modified
by the user, the temporization in progress is interrupted and the timer
reset.
Do not change timer configuration while the temporization
is performing critical functions, as the outputs may be
turned on and off at improper moments.
