2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Purpose
The AZM 415 solenoid interlock has been designed to prevent movable
safety guards, e.g. fences, covers or doors, in conjunction with the
control part of a machine, e.g. fail-safe delay timers or fail-safe standstill
monitors, from being opened before hazardous conditions (e.g. run-on
mouvements) have been eliminated. The AZM 415-33 includes three
switch inserts and is designed for monitoring double safety guards.
Interlocks with power to lock principle may only be used in
special cases after a thorough evaluation of the accident risk,
since the safety guard can be opened immediately on failure
of the power supply or upon activation of the main switch.
The safety switchgears are classified according to
ISO 14119 as type 2 interlocking devices.
Solenoid interlock with manual release AZM 415-33PDKE
The manual release is only used with components that operate on the
power to unlock principle. It is used as a mounting tool and also as a
tool to open a closed and locked safety guard in case of a power failure.
The point of access to the manual release or the manual release itself
must be protected in accordance with the provisions of the professional
association, e.g. by sealing during mounting.
Unlocking:
using triangular key (available as accessory)
Reset:
by turning the triangular key back
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level.
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.
