2 Safety information
2.1 General safety notes
DANGER
If the safety component is integrated incorrectly, the dangerous state may be ended to
late.
bPlan the integration of the safety component in accordance with the machine
requirements, see "Project planning", page 13.
2.2 Intended use
The safety locking device is a locking unit with a safety locking function and is suitable
for the following applications:
•Temporarily preventing access to a hazardous area
•Monitoring of movable physical guards
•Locking for process protection
In conjunction with a movable physical guard and the machine controller, the safety
locking device prevents the protective device from being opened. The locking device
remains locked for as long as the hazardous machine function is performed or until the
production step has finished.
The product is only suitable for use in industrial environments.
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.
2.3 Improper use
The safety locking device is not suitable, among other things, for the following ambient
conditions:
•Outdoor areas
•Residential areas
•Vacuum
•High pressure
•Strong UV exposure
•Near low-frequency transponders (e.g., RFID)
•Near magnetic fields
•Increased radiaoactivity (> natural radioactivity)
•High sulfur concentration
•High salt concentration
2.4 Requirements for the qualification of personnel
The safety locking device must be planned in, 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
experience in the relevant field and is sufficiently familiar with the application of the
protective 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 Design and function
Design
The safety locking device is a locking unit with a safety locking function. The safety
locking device comprises a safety switch with transpondermonitoring and a coded
actuator.
Function
The safety locking device is used on a movable physical guard. The safety switch is
located on the frame of the movable guard, the actuator on the moving part. When the
protective device is closed, the actuator is inserted into the safety switch. The safety
switch reads the code of the actuator. If the code is valid, the safety locking function
can be locked via a signal. The movable guard is held closed.

3.2.2 Locking principle
Overview
The method of locking depends on the safety locking device variant selected. There are
two variants:
•Power to lock
•Power to release
Important information
DANGER
Hazard due to lack of effectiveness of the protective device
For power to lock variants only: In the event of a voltage drop, the locking device
unlocks regardless of whether the dangerous state of the machine has ended.
bDo not use the safety switch in applications in which the dangerous state cannot
be ended immediately (stopping/run-down time).
Power to lock
•Lock locking device: voltage at locking device input
•Unlock locking function: no voltage at locking device input
If voltage is interrupted, the locking device is unlocked and protective device can be
opened immediately.
Power to release
•Lock locking device: no voltage at locking device input
•Unlock locking device: voltage at locking device input
If the voltage is interrupted, the locking device retains its last state (bistable coil). If the
locking device was locked before, the protective device cannot be opened. If the locking
device was not locked before, the protective device can be opened.
Only the power to release variants have a mechanical unlocking mechanism.
3.2.3 OSSD
Output signal switching device: signal output for the protective device, which is used for
stopping the dangerous movement.
An OSSD is a safety switching output. The functionality of each OSSD is tested periodi‐
cally. OSSDs are always connected in pairs and must undergo dual-channel analysis for
safety reasons. An OSSD pair is formed from 2 OSSDs that are connected and analyzed
together.
3.2.4 Switching behavior of the OSSDs
Overview
The safety locking device is available in variants for protecting people or for process
protection. The variants differ with regards to the switching behavior of the OSSDs:
Variants for people protection (locking monitoring)
OSSDs go into the ON state as soon as the following requirements are all fullfilled.
•Movable physical guard is closed.
•Locking device is locked.
•There is a valid signal at the inputs In1 and In2.
