CAUTION
Carefully assess risk conditions and reset modes. In applications protect-
ing access to dangerous areas, the automatic reset mode is potentially
unsafe if it allows the operator to pass completely beyond the sensitive
area.
In this case, the manual reset or, for example, the manual reset of the SE-
SR2 relay (see "
) is necessary.
