2.4 Purpose
The non-contact, electronic solenoid interlock is designed for
application in safety circuits and is used for monitoring the position and
locking of movable safety guards.
The safety switchgears are classified according to ISO 14119
as type 4 interlocking devices. Designs with individual coding
are classified as highly coded.
The first of the two safety functions is the safe shut-down of both safety
outputs when unlocking or opening the guard system and making sure
that the switched-off position is maintained when the guard system is
open or unlocked (locking function).
The second safety function (interlocking function) is the safe
interlocking of a guard system which was locked only once. The locking
of the guard system may only be switched off when there is no fault and
a valid signal to unlock is present.
When the guard system is closed and there is a valid two-channel control
signal applied by the user or through the controller, the locking bolt of the
AZM400 can be driven out. As soon as the locking bolt have reached
sufficient depth in the locking hole the guard system is considered to be
safely locked.
The AZM400 solenoid interlock is a bi-stable system, which means the
interlock remains in the last position if power is lost.
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level.
If multiple safety sensors are involved in the same safety
function, the PFH values of the individual components must
be added.
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.
