2 Safety information
2.1 General safety notes
The safety locking device must be configured and operated correctly by qualified safety
personnel according to the machine requirements.
2.2 Intended use
When used in conjunction with a movable physical guard and the machine controller,
the 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.
2.3 Requirements for the qualification of personnel
The safety locking device must be configured, installed, connected, commissioned, and
serviced only by qualified safety personnel.
Project planning
For project planning, a person is considered competent when he/she has expertise and
experience in the selection and use of protective devices on machines and is familiar
with the relevant technical rules and national work safety regulations.
Mechanical mounting, electrical installation, and commissioning
For the task, a person is considered qualified when he/she has the expertise and expe‐
rience in the relevant field and is sufficiently familiar with the application of the protec‐
tive device on the machine to be able to assess whether it is in an operationally safe
state.
Operation and maintenance
For operation and maintenance, a person is considered competent when he/she has
the expertise and experience in the relevant field and is sufficiently familiar with the
application of the protective device on the machine and has been instructed by the
machine operator in its operation.

3 Product description
3.1 Setup and function
The safety locking device is an interlocking device consisting of a mechanically-actu‐
ated position switch and a coded actuator. The actuator has a lower coding level. The
position switch contains a rotating switching cylinder which the actuator grips during
closing. The switching cylinder is locked or unlocked electromagnetically (variant-depen‐
dent).
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.
3.2 Product characteristics
3.2.1 Product variants
The safety locking device is delivered in different variants. You will find an overview of
important distinguishing features of the variants in the following.
•Type of contacts for locking device monitoring
Complete overview of all variants: see "Ordering information", page 22
Standby current locking principle
i14-M
•Locking locking device: close protective device, no voltage on the magnet
•Unlocking locking device: apply voltage to magnet
If voltage is interrupted at the magnet, the locking device remains locked and the pro‐
tective device cannot be opened immediately.
WARNING
The locking device locks even when voltage is not present
People could get trapped.
bIf people are in the hazardous area, do not close the protective device even volt‐
age is not present.
3.2.2 Locking device monitoring
All variants feature 3 contacts for locking device monitoring. At least 2 contacts are
always positive opening normally closed contacts. Depending on the product variant, 1
contact can be a normally open contact. The output state changes when locking or
unlocking the locking device.
3.2.3 Status indicators
The safety locking device outputs the status of the locking device using the light emit‐
ting diode.

3.4 Manual unlocking
In some situations, it necessary to unlock the locking device manually (e.g. is faults are
present). After unlocking, a function test must be performed.
Mechanical unlocking mechanism
With the mechanical unlocking mechanism, the safety locking device can be unlocked
regardless of the status.
When actuating the mechanical unlocking mechanism, the contacts for locking device
monitoring open. A stop command must be generated.
Actuating the mechanical unlocking mechanism
bEnsure tensile stress is not applied on the actuator.
bUse the screwdriver to rotate the mechanical unlocking mechanism in the direc‐
tion of the arrow to the following symbol:
✓The locking device is unlocked.
WARNING
Permanent actuation of the mechanical unlocking mechanism
Hazard due to lack of effectiveness of the protective device
bPut back mechanical unlocking mechanism after use.

4.1 Manufacturer of the machine
DANGER
Failure to comply with manufacturer’s obligations
Hazard due to lack of effectiveness of the protective device
bCarry out a risk assessment before using the safety locking device.
bDo not tamper with or modify the components of the safety locking device.
bMake sure that the safety locking device is only repaired by the manufacturer or by
someone authorized by the manufacturer. Improper repair can lead to a loss of the
protective function.
bMake sure that switch-on commands which bring about a dangerous state of the
machine are not enabled until the protective device is closed and the lock is acti‐
vated.
bMake sure that the lock is not deactivated until the dangerous state of the
machine has stopped.
bMake sure that closing a protective device and activating the lock does not cause
a dangerous machine function to start by itself. This must be controlled by a sepa‐
rate start command.
bThe safety locking device must not be bypassed (contacts jumpered), turned away,
removed, or rendered ineffective in any other way. Take measures to reduce
bypassing options as necessary.
If several devices are switched in succession and the simplified process according to
ISO 13849 is used to determine the performance level (PL), the PL may be reduced.
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.
4.1.1 Application 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).
