1 Overview
1.1 Introduction
The TBL series safety interlocking device is used for interlocking and guard locking, with RFID monitoring and a
coded actuator. The safety locking device can be actuated horizontally within a 180° radius with infinite adjustment.
When the actuator is close to the sensor, the actuator is activated by the electromagnetic field of the sensor and obtains
energy. The actuator responds to the instructions and information sent by the sensor. The sensor determines and
identifies the actuator identity, after received the information sent by the device. The actuator is within the detection
range or not by whether the sensor received the response message of actuator correctly. The sensor is installed in a
fixed position of the door frame, and the actuator is installed on a movable part such as a door. Thus, you can know the
door is open or closed by test the detection results of the sensor.
The TBL series safety interlocks are suitable for the following usage scenarios:
• Removable physical protective equipment
• Safe location monitoring

7.1 Cascade function
Safety input is one of the conditions for controlling the ON output of OSSD, and it is also the input signal for series
connection application. Safety input 1 and safety input 2 are a pair of safety inputs. If safety input 1 or safety input 2 turns
OFF state, OSSD turns OFF.
Connecting OSSD with other safety interlocks on the safety input can cascade multiple sets of safety interlocks.

Note: OSSD turns ON only when all conditions except for lock input are met.
7.2.2 Lock input for basic function model
The basic functional Lock input has only one input signal.
Sequence Diagram:
Note: OSSD turns ON only when all conditions except for lock input are met.
7.2.3 Lock states

DANGER!
Power ON lock type: Lock will release when product is power OFF, which may cause harm to people
depending on device’s operating conditions.
Power ON release type: NPN type may lock release when product is power OFF, which may cause
harm to people depending on device’s operating conditions.
7.3 Reset function
The reset function is used to start/restart the safety output. When all other conditions are met, a valid reset signal
can be input to enable the safety output. This feature can prevent the device from accidentally staring or restarting.
Reset signal is a single channel input signal with two reset modes: automatic reset and manual reset.
Automatic reset mode: without reset signal input detection, so the reset result is valid in any state of eset signal.
Manual reset mode: detect the positive pulse of the reset signal input as OFF->ON->OFF, and it is effective when
the pulse width is within the range of 50~3000ms.
The reset timing of manual reset mode is shown in the following figure:
Note：T1 = 50 ~ 3000ms
7.4 EDM function
EDM is used to monitor the function of external devices whether work properly, and to determine based on the logical
relationship between OSSD output states and EDM input signals.
7.5 Safety output
OSSD1 and OSSD2 are a pair of safe outputs that output the same state, and OSSD1 and OSSD2 are always
turned on/off at the same time.
When there is a fault, the OSSD output will immediately shut down.
7.5.1 Open-close linkage mode:
Automatic reset: During normal operation, OSSD will only ON when the key sensing and safety input are valid;
Otherwise, OSSD will turn OFF.
Manual reset: During normal operation, OSSD will only open when a valid reset pulse is inputted under the
conditions of effective key sensing and safety input; Otherwise, OSSD will turn OFF.
7.5.2 Lock linkage mode:
Automatic reset: During normal operation, OSSD will only ON when the key sensing, safety input, and Lock input are
valid; Otherwise, OSSD will turn OFF.
16
Ver. 1.5
Manual reset: During normal operation, the OSSD will only ON when a valid reset pulse is input, provided that the
key sensing is effective, the safety input is effective, and the Lock input is effective; Otherwise, OSSD will turn OFF.
7.5.3 OSSD Self-diagnostic
Self-diagnostic timing diagram when the OSSD output is ON:
The OSDD will turn OFF state immediately when the OSSD output detects a fault.
7.6 AUX output
AUX1 and AUX2 are respectively auxiliary outputs indicating different working states.
The indication states of AUX output are as follows:
Door approaching (positive): when Door is closed (RFID is valid), AUX output ON, otherwise output OFF;
Door approaching (negative): when Door is closed (RFID is valid), AUX output OFF, otherwise output ON;
Door approaching (positive): when Door is closed and locked (RFID is valid), AUX output ON, otherwise
output OFF;
Door approaching (negative): when Door is closed and locked (RFID is valid), AUX output OFF, otherwise
output ON;
Door locking (positive): when Door is closed and locked (RFID is valid), AUX output ON, otherwise output
OFF;
Door locking (negative): when Door is closed and locked (RFID is valid), AUX output OFF, otherwise output
ON;
Safety input state (positive): when safety input is valid, AUX output ON, otherwise output OFF;
Safety input state (negative): when safety input is valid, AUX output OFF, otherwise output ON;
Auxiliary output (positive): when OSSD state is ON, AUX output ON, otherwise output OFF;
Auxiliary output (negative): when OSSD state is ON, AUX output OFF, otherwise output ON;
System fault indicator (positive): when system is in fault state, AUX output ON, otherwise output OFF;
17
Ver. 1.5
System fault indicator (negative): when system is in fault state, AUX output OFF, otherwise output ON;
DANGER!
AUX output cannot be use as safety input for safety-related control system.
7.7 Actuator code
The actuators are divided into universal code types and unique code types.
Universal code: the actuator can be matched with any safety interlock;
Unique code: The actuator can only match one safety interlock and does not allow the actuator to simultaneously
match multiple safety interlocks. Once an actuator is successfully matched, the actuator will have no response to safety
interlocks other than the one that has been matched.
In the unique code mode, the match process of the actuator is:
1. Ensure that the output is in safe sate;
2. After the safety interlock is activated, it enters the waiting state for unique code match, indicting: red, green
light 4Hz flashing alternatively;
3. Insert the to be matched actuator into safety interlock and waiting for it to complete match;
4. The safety interlock will enter normal operate sate after successfully matching.

9 Installation
9.1 Installation dimensions for safety interlock with actuator
WARNING!
Install the safety switch and actuator so that the possibilities of defeat are reduced to a minimum
(see guidelines for reducing the possibilities for defeating interlocking devices in ISO 14119).
Install safety switch and actuator so that it is not possible to reach through with hand or finger.
9.1.1 TBL standard TBL-K3R curvy actuator
WARNING!
• Arrange the safety interlock and actuator so that damage due to unintentional outside
influences is prevented.
• Protect the switch head against damage and ingress of foreign bodies, e.g., chips, sand,
abrasives, etc.
• Check for environmental influences before using the safety locking device, e.g., UV radiation or
corrosion. Mount with protection if necessary.

Ver. 1.5
9.2.3 TBL-H94 Emergency unlock button（Press 88mm, Reset 94mm)
WARNING!
Incorrect installation of the escape release means that the button of the escape release pin can be
accessed from the outside. This may mean that the guard locking is unlocked from the outside and
the safety gate is opened, although the hazardous machine is switched on.
The escape release should be installed so that it is only accessible from inside the danger zone.
The button of the escape release pin must be impossible to reach from a position outside the protected area.
Prevent any unintended operation of the escape release.
Prevent the effect of transverse forces on the escape release.
Secure the screw connections with a medium-strength thread locker.
The button of the escape release pin must be clearly visible and it must not be concealed.

10 Commissioning
DANGER!
Hazard due to unexpected starting of the machine-Death or severe injury
Before the function check-out, make sure there is no danger to people.
Immediately put the machine out of operation if you cannot clearly identify or allocate the error and
if you cannot safely remedy the error.
After installation, after every error and after modifications to the application, check that the device is functioning
correctly. Perform the following checks.
10.1 Mechanical check
Open the movable physical guard and close it again. The components of the safety locking device must not collide
with other parts while doing so.
10.2 Function check
1. Switch on the supply voltage.
2. Close all movable physical guards and activate the locking function. The machine must not start independently.
3. Check the locking device. The movable physical guard must not be able to be opened.
4. Start the machine function.
5. Ensure that the locking function cannot be deactivated as long as the dangerous machine function is active.
6. Stop the machine function and deactivate the locking function.
7. Check whether the movable physical guard remains locked until no risk of injury is present anymore (e.g. due to
overrun movements).
8. It must not be possible to start the machine function as long as the movable physical guard is open and not
locked.
9. For emergency escape release: Check the function of the escape release.
WARNING!
The safety functions should be checked after initial commissioning and each time the plant/machine
is changed. The safety functions may only be checked by qualified personnel
11 Maintenance
It is not necessary to perform maintenance work on the product in normal operation. Please return any faulty
products to SHENZHEN TONGCHUANG.
Regular inspection of the switch function is required to guarantee the trouble-free, long-term function.
29
Ver. 1.5
If the interlock and guard locking system is only used rarely (opening and closing the safety gate and
activating/deactivating the guard locking device), a manual function test is required.
The correct function of the device should be checked at regular intervals and after each error.
11.1 Cleaning
Do not use aggressive cleaning agents (e.g. isopropanol, methylated spirits or peroxides).
Do not use any substances that hinder the wetting properties of lacquers.
We recommend anti-static cleaning agents.
11.2 Regular thorough check
The safety switch must be checked regularly.
The regular thorough checks serve to investigate the effectiveness of the safety switch and detect any
ineffectiveness due to modifications or external influences (e.g., damage or manipulation).
Check the functionality of the equipment at least once every 6 months.
To ensure the continuous normal use of the function, the following items need to be checked:
• Proper switching function
• Safe mounting of all components
• No damage, contamination, deposits or wear
• No loose plug connectors
• No signs of tampering
