Usage restrictions
When used as contacts, there are no restrictions on the number of times that can be
used.
For the FP2/FP2SH/FP10SH, if the Initialize/Test switch is set to the upper side (the
Initialize side) in the PROG mode, the timer contact goes off. If a hold type has been
specified, it goes off as well.
Note
With the FP2SH/FP10SH, system register 4 can be set in such a way
that the timer contact is not cleared even if the Initialize/Test switch is
set to the upper side.
