angerous state
D
A dangerous state is a status of the machine or facility, where people may be injured.
Protective devices prevent this risk if the machine is operated within its intended use.
The figures in this document always show the dangerous state of the machine as move‐
ment of a machine part. In practice, there are different dangerous states, such as:
Machine movements
•
Electrical parts
•
Visible and invisible beam
•
A combination of multiple hazards

2Safety information
2.1General safety notes
The safety locking device must be configured and operated correctly by qualified safety
sonnel according to the machine requirements.
per
2.2Intended use
When used in conjunction with a movable physical guard and the machine controller,
t
he safety locking device prevents the protective device from being opened while a dan‐
gerous machine function is being executed.
The safety locking device may only be used on the machine on which it was configured,
mounted, installed, and commissioned by qualified safety personnel in accordance with
these operating instructions.
Incorrect use, improper modification of or tampering with the safety locking device will
invalidate any warranty from SICK AG; in addition, any responsibility and liability of SICK
AG for damage and secondary damage caused by this is excluded.
NOTE
The safety locking device is also suitable for process protection.
SAFETY INFORMATION 2
2.3Requirements for the qualification of personnel
The safety locking device must be configured, installed, connected, commissioned, and
viced only by qualified safety personnel.

RODUCT DESCRIPTION
3Product description
3.1Setup and function
The safety locking device is an interlocking device consisting of a mechanically-actu‐
ted position switch and a coded actuator. The actuator has a lower coding level. The
a
position switch contains a rotating switching cylinder which the actuator grips during
closing. The switching cylinder is locked or unlocked electromagnetically (variantdependent).
When inserting and removing the actuator, switching contacts for door monitoring are
opened and closed. When locking and unlocking the locking device, switching contacts
for locking device monitoring are opened and closed.
If the locking device is locked, the actuator cannot be removed from the actuating head.
The locking device can only be locked when the protective device is closed.
3.2Product characteristics
3.2.1Product variants
The safety locking device is delivered in different variants. You will find an overview of
im
portant distinguishing features of the variants in the following.

In the event of a voltage drop, the safety locking device unlocks regardless of whether
the dangerous state of the machine has ended.
Assess the risk of accident. Use for protecting people requires correct project plan‐
b
ning.
3.2.2Locking device monitoring
All variants feature at least 1 positive opening normally closed contact for locking
vice monitoring. The output state changes when locking or unlocking the locking
de
device.
Variants with 2 positive opening normally closed contacts for locking device monitoring
are recommended to protect people.
3.2.3Door monitoring
All versions feature 3 contacts for door monitoring. 2 contacts are positive opening nor‐
mall
y closed contacts. 1 contact is a normally open contact. The output state changes
when opening or closing the protective device.

Hazard due to lack of effectiveness of the protective device
Carry out a risk assessment before using the safety locking device.
b
Do not tamper with or modify the components of the safety locking device.
b
Make sure that the safety locking device is only repaired by the manufacturer or by
b
someone authorized by the manufacturer. Improper repair can lead to a loss of the
protective function.
Make sure that switch-on commands which bring about a dangerous state of the
b
machine are not enabled until the protective device is closed and the lock is acti‐
vated.
Make sure that the lock is not deactivated until the dangerous state of the
b
machine has stopped.
Make sure that closing a protective device and activating the lock does not cause
b
a dangerous machine function to start by itself. This must be controlled by a sepa‐
rate start command.
The safety locking device must not be bypassed (contacts jumpered), turned away,
b
removed, or rendered ineffective in any other way. Take measures to reduce
bypassing options as necessary.
PROJECT PLANNING 4
If several devices are switched in succession and the simplified process according to
O 13849 is used to determine the performance level (PL), the PL may be reduced.
IS
A logical series connection of safe contacts may be possible up to PL d under certain
circumstances. For more detailed information, see ISO TR 24119.
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.
4.1.1Application of the safety locking device to protect people
At least one safe contact must be used for locking device monitoring (contact assign‐
ment see
table 3).
4.1.2Application 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 see
table 3).

Hazard due to lack of effectiveness of the protective device
Changes to the machine and changes to the mechanical mounting of the safety

tions.
Apart from the procedures described in this document, the components of the
b
safety locking device must not be opened or modified.
Do not carry out any repair work on components. Improper repair of the safety
b
locking device can lead to a loss of the protective function.
Make sure that replacement actuators are not used for bypassing. Restrict access

Hazard due to lack of effectiveness of the protective device
Eliminate any temptation to tamper with the safety locking device by taking at least
b
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).
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 unintentional out‐
b
side influences is prevented.
Do not use safety switch and actuator.
b
The set-up and mounting of the safety switch and actuator must be stable enough
b
to maintain proper operation.
Use only reliable mounting elements that can only be removed with tools.
b
If an opening is created in the physical guard due to alignment errors, it must not
b
impair the protective function.
5.2Converting the actuating head
1.Insert the actuator into the actuating head.
Loosen screws on the cover and lift the cover.
2.
3.Remove plastic dowel pins and loosen actuating head.
4.Turn the actuating head in the desired direction.
5.Depending on the locking forces, fasten the actuating head with plastic dowel pins
or metal bolts.
6.Rotate metal insert by 180° by loosening the 2 fixing screws.
7.Seal unused actuation slots with the supplied slot covers.

the actuator must be in a position which enables the lock to be actuated.
Electrical functional test
1.Switch on the supply voltage.
2.Close all protective devices and activate the locks. The machine must not start up
on its own.
3.Check the lock. It must not be possible to open the protective device.
4.Start the machine function.
5.Make sure that the lock cannot be deactivated as long as the dangerous machine
function is active.
6.Stop the machine function and deactivate the lock.
7.Check whether the protective device is kept locked until there is no more risk of
injury (e.g., due to run-on movements).
8.Check the restart interlock. The machine function must not start while the lock is
deactivated.
