The blue Test/Reset buttons on the basic unit and the operator
panel are usually intended for acknowledging faults and for carrying
out a device test.
The buttons can be blocked via "Test/Reset buttons blocked". These
can then be used for other purposes. On the operator panel with
display, blocking is carried out via the corresponding menu function.
