In the solenoid interlocks of the EX-AZM series, the switching element with interlocking device and the actuator
are not physically connected, but brought together or separated upon switching. When the safety guard is opened in the
unlocked condition, the actuator is separated from the base unit. During this process, the NC contacts are positively opened
and the NO contacts closed. Interlocking is carried out by means of a blocking bolt / latching bolt. This
latching bolt blocks the actuator so that it cannot be withdrawn from the interlock. The machine control is only
enabled when the actuator has been inserted into the interlock and the latching bolt is in the blocking position. This
is ensured by the contact monitoring of the latching bolt.
