SICK TR10 Lock

3 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.
If the protective device is closed, the actuator is led to the safety switch. If the actuation
field is reached, the actuator code is read out and evaluated by RFID. If the code
is valid, the application diagnostic output switches to the OFF state. When a locking
command is active, the locking pin in extended. Not until the locking pin is detected
in the correct position in the actuator by the integrated proximity sensor is the locking
successful and the safe output signal switching device (OSSD) are switched in the ON
state.
The safety locking device can only be locked when the protective device is closed.
The locking pin is actuated by a bistable magnetic solenoid. As a result, the safety
locking device has a low power consumption and does not give off any heat. The safety
locking device function is nevertheless implemented according to the power to release
or power to lock principle via the electronics.
3.2 Product characteristics
3.2.1 Product variants
The safety locking device is delivered in different variants. An overview of important
distinguishing 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 39
Variant according to “power to release” principle
•
Activate lock: no voltage at lock input
•
Deactivate lock: voltage at lock input
If voltage is interrupted, the locking device remains locked 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.
