The safety locking device is designed so that internal errors according to ISO
13849-2, Table A4, can be ruled out.
Observe EN ISO 14119 for using interlocking devices associated with physical
guards.
4.1.1
Application of the safety locking device to protect people
At least one safe contact must be used for locking device monitoring (contact
assignment
see table 11
).
4.1.2
Application of the safety locking device for process protection
At least one safe contact must be used for door monitoring.
Contacts for locking device monitoring can also be used (pin assignment
table 11
).
4.2 Operator of the machine
Changes to the electrical integration of the device in the machine controller
and changes to the mechanical mounting of the device necessitate a new risk
assessment. The results of this risk assessment may require the entity operating
the machine to meet the obligations of a manufacturer.
The device must not be tampered with or changed, except for the procedures
described in this document.
The device must not be repaired. Improper repair can result in the device not
providing correct protection.
Restrict access to replacement actuators so they are not used to circumvent the
device.
4.3 Design
DANGER
Bypassing the protective device
Hazard due to lack of effectiveness of the protective device
Eliminate any temptation to tamper with the safety locking device by
b
implementing measures such as the following:
°
Attach safety switches with a cover or with shielding, or ensure they
are out of reach.
°
Cover the safety switch and the actuator with additional equipment
or protect them against access. Cover the sensor and the actuator
with additional equipment or protect them against access.
4.3.1
Selection of the actuator
NOTICE
Selecting unsuitable actuators or improper mounting can damage the device.

Pay attention to the door radius and mounting options.

4.4 Integrating into the electrical control
Switch-on commands which bring about a dangerous state of the machine must
not be enabled until the protective device is closed and the lock is activated. The
lock must not be deactivated until the dangerous state has ended. Depending
on the safety concept, the signal is analyzed by, e.g., safety relays or a safety
controller.
The connected controller and all devices responsible for safety must comply with
the required performance level and the required category (for example according
to ISO 13849-1).
You must validate the overall concept of the control system in which the safety
switch is integrated according to ISO 13849-2 or evaluate it according to EN
62061.
4.5 Testing plan
The safety locking device must be tested by appropriately qualified safety person‐
nel when commissioning, after modifications, and at regular intervals.
The regular thorough checks serve to investigate the effectiveness of the safety
locking device and discover defects because of modifications or external influen‐
ces (such as damage or tampering).
The manufacturer and user must define the type and frequency of the thorough
checks on the machine on the basis of the application conditions and the risk
assessment. Determination of the thorough checks must be documented in a
traceable manner.

DANGER
Bypassing the protective device
Hazard due to lack of effectiveness of the protective device
Eliminate any temptation to tamper with the safety locking device by
b
taking at least one of the following measures:
°
Attach safety switches with a cover or with shielding, or ensure they
are out of reach.
°
If possible, use permanent mounting methods for actuators (e.g.,
welding, glue, disposable screws, or rivets).
CAUTION

Risk of burns
see
At ambient temperatures > 40 °C, protect the safety locking device from
b
unintentional touching by people.
NOTICE
If incorrectly installed or the ambient conditions are not suitable, the safety
locking device can get damaged.
Arrange the safety switch and actuator so that damage due to uninten‐
b
tional outside influences is prevented.
Do not use safety switch and actuator.
b
The set-up and mounting of the safety switch and actuator must be
b
stable enough to maintain proper operation.
Use only reliable mounting elements that can only be removed with
b
tools.
If an opening is created in the physical guard due to alignment errors, it
b
must not impair the protective function.
At ambient temperatures > 40 °C, protect the safety switch from con‐
b
tact with flammable materials.
The specified IP enclosure rating only applies if the housing screws,
b
cable entries, and plug connectors have been fastened correctly.
Observe the tightening torque.
5.2 Converting the actuating head
1.
Insert the actuator into the actuating head.
2.
Loosen the screws on the actuating head.
3.
Turn the actuating head in the desired direction.
Figure 1: Converting the actuating head
4.
Tighten the screws to 0.8 Nm.
5.
Seal unused actuation slots with the supplied slot covers.
5.3 Mounting
1.
Insert the actuator into the actuating head.
2.
Connect the safety switch to the fixed part of the protective device with
positive locking.
3.
Connect the actuator permanently to the moving part of the protective
device so it cannot be disengaged.
4.
Fit an additional stop for the moving part of the protective device.
5.4 Protection from environmental influences
The prerequisite for a proper and permanent safety function is protection of the
actuating head from foreign bodies such as chips, sand, beams of light, etc.
When doing painting work, cover the actuation slot, the actuator and the type
label.
