2.3 Comprehensive quality insurance to 2006/42/EC
Schmersal is a certified company to appendix X of the Machinery
Directive. As a result, Schmersal is entitled to autonomously conduct
the conformity assessment procedure for the products listed in
Appendix IV of the MD without involving a notified body. The prototype
test certificates are available upon request or can be downloaded from
the Internet at www.schmersal.com.
2.4 Purpose
The non-contact, electronic safety switchgear 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 different variants can be used as safety switch with interlocking
function either as solenoid interlock.
If the risk analysis indicates the use of a monitored interlock
then a variant with the monitored interlock is to be used,
labelled with the symbol.
The actuator monitoring variant (B) is a safety switch with an
interlock function for process protection.
The safety function consists of safely switching off the safety outputs
when the safety guard is opened and maintaining the safe switched off
condition of the safety outputs for as long as the safety guard is open.
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.
Conditions for safe operation
The specific ambient temperature range must be observed.
The user must provide for a protection against the permanent
influence of UV rays.
The component must be mechanically protected. In order to
provide for an increased mechanical protection, the solenoid
interlock must be fitted with an additional protective enclosure
(included in delivery).
Series-wiring
Series-wiring can be set up. Response and risk times remain
unchanged by series-wiring. The number of components is only limited
by the external cable protection according to the technical data and
the line loss. Series-wiring of up to 31 EX-AZM300 … SD components
with serial diagnostics is possible. In devices with the serial diagnostics
function (ordering suffix -SD), the serial diagnostics connections
are wired in series and connected to a SD Gateway for evaluation
purposes. Wiring examples for series-wiring, refer to appendix.
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.

The safety consideration of the guard locking function only
applies for standard devices with monitored solenoid interlock
EX-AZM300Z-…-1P2P-… (see Ordering code). A safety
assessment of the guard locking function for devices with
serial diagnostics "SD2P" is not allowed due to the non-safe
locking/unlocking signal from the SD Gateway
The actuation of the interlock must be compared with the
external OSSD enabler. If a shut-down now occurs due to
an unintentional unlocking this is detected by an external
diagnostic.

Operating instructions
Solenoid interlock EX-AZM300
EN
If for a certain application the power to unlock version of
a solenoid interlock cannot be used, then for this exception
an interlock with power to lock can be used if additional
safety measure need to be realised that have an equivalent
safety level.
The safety analysis of the guard locking function refers to
the component solenoid interlock EX-AZM as part of the
complete system.
On the customer side further measures such as safe
actuation and safe cable installation to prevent faults are to
be implemented.
In the event of a fault resulting in the unlocking of the guard
locking, this is detected by the solenoid interlock and the
safety gates Y1/Y2 switch off. When such a fault occurs
the protection equipment may open immediately, just once,
before the safe condition of the machine is reached. The
system reaction of category 2 allows that a fault can occur
between tests causing the loss of the safety function which is
detected by the test.
3. Mounting
3.1 General mounting instructions
Please observe the relevant requirements of the standards
ISO 12100, ISO 14119 and ISO 14120.
Any mounting position.
For attachment of the solenoid interlock and the actuator, two mounting
holes for M6 screws are provided.
A washer (2 mm) for symmetrical mounting of the solenoid interlock to
the protective enclosure is included in the delivery. We recommend the
use of washers for mounting of the actuator.
Tightening torque of the fixing screws:
- Solenoid interlock: 8 Nm
- Actuator: 5 … 6 Nm
The actuator must be permanently fitted to the safety
guards and protected against displacement by suitable
measures (tamperproof screws, gluing, drilling of the screw
heads).
The solenoid interlock can be used as an end stop.
Dependant upon the door weight and the actuating speed,
the mechanical life could be reduced.
Actuation direction
Provide for a sufficient insertion of the actuator into the
rotary handle.
The system must only be operated with an angle of ≤ 2° between the
solenoid interlock and the actuator.
When mounting the solenoid interlock onto metallic surfaces, a galvanic
connection must be realised between the mounting surface and fixing
point "A".

To avoid any interference inherent to this kind of system and any
reduction of the switching distances, please observe the following
guidelines:
• The presence of metal chips in the vicinity of the solenoid interlock is
liable to modify the switching distance.
• Keep away from metal chips.
3.2 Manual release
For the machine set-up, the solenoid interlock can be unlocked in a
de-energised condition. The solenoid interlock is unlocked by turning
the manual release in the position
Q
.
The normal locking function is only restored after the manual release
has been returned to its original position
P
.
Caution: do not turn beyond the end stop!
After being put into operation, the manual release must be sealed by
means of the seal, which is included in delivery.
