(RESET) the protective device if this can cause a dangerous state
(cf. EN 60204).
In this case an additional measure must be provided, e.g. the

Error monitoring

The evaluation unit checks the system for errors when the protective
device is opened and closed (from the sensor to the output on the
evaluation unit including monitoring of the relay contacts). If an error
is detected, the evaluation unit is placed in an inhibited state (red
"ERROR" LED flashes; green "OUTPUT" LED off with protective
devices closed and open, green "POWER" LED illuminated). See also
chapter 4.4 "Lifting the inhibit in the case of an error".
