Adjust the smoothness of opening and closing

If the door does not open and close smoothly after installation, the locking machine meter screw (1.5mm on the opposite side) can also be removed and used again. Since the door is easy to open in this case, please prepare a door suction product as required

Danger

• To reduce the probability of invalidation, install the TRL1 safety door lock in a location that is not easily accessible (e.g., out of reach, with physical shielding or railings, in a hidden location). Or it can be secured in a non-removable manner to prevent the TRL1 safety lock from being removed or moved.
• For more information on minimizing the probability of invalidation, refer to ISO14119.
• The actuator, inductor and other mounting brackets should be fixed according to the installation size requirements.
• During installation, apply thread glue of medium strength to the screws to prevent the screws of the TRL1 safety door lock sensor and actuator mounting bracket from loosening.
• If the special mounting bracket is not suitable for installation, please consult our product sales personnel.

Attention

• When installing a revolving door, ensure that the revolving radius of the door is greater than 220mm.
• When replacing the actuator or inductor, follow the same procedure.
• Prepare additional screws (M4) for attaching the actuator, inductor, and mounting bracket to the device.

Instructions for unlocking

1. When manual release is required, please use a screwdriver or a manual knob accessory to turn the TRL1 sensor front release knob clockwise from to . At this time, the TRL1 sensor will not be able to lock the TRL1 actuator. To restore the locking function, you need to turn the TRL1 sensor front release knob counterclockwise from to .
2. TRL1 safety lock can work normally only when the front release knob and the back release knob are at position at the same time.
   Cross release knob
   Triangle release knob

Warning

• For the electromagnetic locking model, it is prohibited to turn the manual release knob from to position when the product is locked, otherwise it will cause irreparable damage to TRL products;
• For the electromagnetic locking model, when the door is opened, turn the manual release knob from to , and then give the door locking signal, which will not provide the locking force for the safety door. If the product needs to work normally again, you need to turn the manual release knob to position.

Installation and Use Instructions for Rear Release Fitting TRL1-H03

1. Locate and punch the TRL1 sensor mounting piece (75~45mm thick) with a diameter ≥ 32mm, which is used to install the rear release fitting TRL1-H03, and install and fix the TRL1 sensor with four M4 screws
   • Insert the TRL1-H03 torsion bar of the rear release fitting into the positioning shaft of the rear release fitting as shown in the figure, and align the convex point of the positioning shaft and the screw mounting hole with the positioning hole and screw hole of the TRL1 sensor respectively, so as to ensure that the cross bone position of the back release torsion bar is inserted into the cross slot of the TRL1 sensor, and rotate the back release torsion bar to
     unlock the TRL1 sensor
   • Fix the locating shaft of the back unlocking handle at the installation position of the TRL1 actuator with two M4 screws
   • Fix the mounting plate of the rear release fitting on the TRL1 sensor mounting plate with four M4 screws (note that the marking direction of the mounting plate needs to be consistent with the actual unlocking direction; the screw length needs to be determined according to the thickness of the mounting part, and the TRL1 sensor cannot be contacted)
   • Install the TRL1 back release handle handle into the TRL1 back release handle torsion bar, and fix them with accessory screws as shown in ⑥.

Avoid mutual interference

When multiple TRL1 safety door locks are used, mutual interference may occur, which may lead to incorrect operation of TRL1 safety door locks. To prevent
mutual interference, please install TRL1 safety door lock according to the following regulations.

OSSD output self diagnosis timing

TRL1 safety lock has output self diagnosis function. During the TRL1 safety lock output continuity, the TRL1 safety lock internal control timing control unit periodically and actively turns off the OSSDA and OSSDB outputs in turn. During the brief shutdown of OSSDA or OSSDB, the TRL1 safety lock internal timing control unit detects whether OSSDA or OSSDB is indeed closed. If it is indeed closed, the corresponding OSSD switch is in normal working state. If OSSD is not detected to be closed, the corresponding OSSD fails, and the system will immediately shut down both OSSDs. At this time, the TRL1 safety lock red
indicator flashes to ensure functional safety. Therefore, when the load connected to the safety lock is a PLC or a fast intelligent device with MCU control, it is necessary to filter the self-test pulse in the program. The following figure is the TRL1 safety lock self diagnosis output waveform sequence diagram.

※Devices connected to the OSSD, such as safety relays or contactors, should not react to these temporary, self diagnostic shutdown signals.

Unique encoding actuator uses matching

TRL1 safety locks are classified into generic and unique coding types.※
Unique Code Type The TRL1 safety door lock has no unique code before delivery. You need to match the code
with the TRL1 actuator (door key) only when you use it for the first time.
After the green light flashes three times, the red light flashes for 1s, then flashes twice at 2Hz, and repeat. The other lights are off (unique code).

For sensors that have not completed coding matching, coding matching shall be performed as follows:

1. Use the TRL1 actuator (door key) provided by our company to insert the unmatched TRL1 safety door lock;
2. Power on the TRL1 safety lock. After the TRL1 safety lock that does not match the code is powered on and initialized successfully (the green light blinks three times), it enters the matching mode, and the traffic light blinks alternately and rapidly.
3. TRL1 safety door lock will read the code of TRL1 actuator (door key);
4. After 5 seconds, the TRL1 safety door lock matches the code successfully, and the traffic lights stop flashing alternately;
5. Please power off and restart the TRL1 safety lock.

※Once the unique code type TRL1 safety door lock matches the code of a TRL1 actuator (door key) successfully, this TRL1 safety door lock can only identify the matched TRL1 actuator (door key), but not other TRL1 actuators (door key) during use.

Attention

• The actuator must be matched for the first use.
• In the process of actuator matching, do not power off or move the actuator, otherwise the matching will fail.
• After matching the actuator and inductor, they can only be used in pairs, and the inductor can no longer identify other actuators.
