Product description
3.1
Setup and function
The safety locking device is an interlocking device with a lock consisting of a non-con‐
tact safety switch and a coded actuator. Depending on the product variant, the actuator
either has a low (universally coded) or high (unique coded) coding level.
When the protective device is closed, the actuator is guided to the safety switch. When
the actuation field is reached, the actuator code is read and analyzed via RFID. If the
code is valid, the application diagnostic output switches. When the locking command is
active, the guard locking pin is extended. If the guard locking pin is detected in the
actuator, the locking process has been successful and the safe output signal switching
devices (OSSD) are switched.
The safety locking device can only be locked when the protective device is closed.
The guard locking pin is actuated by a bistable solenoid. This means that the safety
locking device consumes little electricity and does not produce any heat. Nevertheless,
the function of a safety locking device is executed via the electronics according to the
“power to release” or “power to lock” principle.

Product characteristics
3.2.1
Product variants
The safety locking device is delivered in different variants. An overview of important dis‐
tinguishing features between the variants is provided below.
•
Designed according to “power to release” or “power to lock” principle
•
Versions for universally coded or unique coded actuators
•
Cable with M12 plug connector (0.2 m) or flying leads (3 or 10 m)
Complete overview of all variants:
see "Ordering information for TR10 Lock", page 35
Variant according to “power to release” principle
•
Activate lock: no voltage at lock input
•
Deactivate lock: voltage at lock input
When the voltage at the lock input is interrupted, the lock remains activated and the
protective device cannot be opened immediately.
Variant according to “power to lock” principle
•
Activate lock: voltage at lock input
•
Deactivate lock: no voltage at lock input
When the voltage is interrupted, the lock is deactivated and the protective device can
be opened immediately.
DANGER
Hazard due to lack of effectiveness of the protective device
If the voltage drops, the safety locking device deactivates regardless of whether the
dangerous state of the machine has ended
b
Assess the accident risk. The device must be configured correctly in order to be
used for protection of personnel.
Variant for universally coded actuators
All universally coded actuators are accepted. No teach-in is required.
