4. Instructions for Using JSY-1 Electromagnetic Control Program Lock
Closing position: When the circuit breaker is in the closing position, the electric lock has no operating power supply, the control circuit is closed, and the circuit breaker can perform opening and closing operations.
Opening position: When the circuit breaker is in the opening position, the indicator light of the electric control lock lights up, indicating that there is operating power. Press the electric control lock button and rotate the mechanical program lock key counterclockwise to remove the key and perform the knife switch operation. After removing the key, the control circuit of this electric control lock is disconnected and the circuit breaker closing operation cannot be performed.
Circuit breaker maintenance: Open the circuit breaker, remove the key from the electric control lock, open the isolation switch, press the electric control lock button, insert the mechanical program lock key into the lock hole of the electric control lock, rotate it clockwise by 50 ° to the red line position, release the button, lock the key, and close the control circuit of the electric control lock. At this time, the circuit breaker opening and closing test or maintenance can be carried out.
Special reminder: After the circuit breaker is in the open position and the mechanical program lock key completes all operations, insert the electronic control lock, turn on the power, and lock the key clockwise 50 ° to the red line position. After completing the operation, turn the key to ensure it is locked before closing.
5. Installation and debugging
Before installation, the specifications of the purchased electric control lock should be checked to ensure that the technical parameters are consistent. After confirmation, a power test should be conducted. The program lock key should be inserted, removed, and rotated freely, with reliable locking and no jamming phenomenon.

If the indicator light does not light up when powered on and the iron core in the coil cannot be heard when pressing the electric control lock button, it indicates that the electric control lock coil is not connected. Further inspection, repair or replacement should be carried out. If the lock bolt cannot lock the program lock key after being powered on and engaged, it indicates that the lock bolt is blocked and stuck after being engaged. At this time, the panel needs to be disassembled to adjust the screws that fix the coil bracket appropriately to restore its work.
7. Ordering Notice
When placing an order, it is necessary to specify the closing current and control voltage of the switch closing contactor, and provide the matching scheme and scheme number for the JSN (W) 1 series mechanical program lock.

5. Environmental conditions: Places without fire, explosion hazards, severe dust, chemical corrosion, and severe vibration, with a pollution level of II.

3�� Model and its meaning

4�� Easy operation instructions
1. Control switch lock
Replace the original control switch panel and handle with a control switch lock. Insert the program key into the hole at the bottom of the lock panel, then insert the red card and turn the handle clockwise to close the switch. Replace the green card and turn the handle counterclockwise to open the switch. When in the pre opening position, the program key will not be removed. This lock has an emergency unlocking device (white plate)
Attention: When the control switch is locked without a matching conversion switch, do not turn it 360 degrees to prevent damage. It can only be tested between merging and splitting.
2. Knife Lock
When opening the switch: Insert the key into the slot marked with the "close" character, turn the key clockwise to align the engraved line on the key. Pull out the locking pin and operate the isolation switch handle. After the switch is opened, the lock pin automatically resets, and the key continues to rotate clockwise into place. Remove the key from the slot marked with the "open" character to lock it. Align with the opening.
When closing the lock, insert the key into the slot marked with the word 'separation', and turn the key counterclockwise to align the engraved line on the key with the engraved line on the lock body. Pull out the locking pin and operate the isolation switch handle. After closing, the locking pin will automatically reset, and the key will continue to rotate counterclockwise into place. Pull out the key from the slot marked with the "close" character to lock it. Align with when closing.
Attention: It is not allowed to operate the lock with both hands at the same time during operation (i.e. one hand operates the key and the other hand pulls the locking pin)
3. Cabinet door lock
When opening the door, insert the key into the lock hole of the mesh door lock, turn the key clockwise into place, and remove the key to open the mesh door. When closing the door, insert the key into the lock hole of the mesh door lock, close the door, turn the key counterclockwise into place, and remove the key to lock the mesh door.
Except for the control switch lock, each set of locks on other lock bodies has its own operation sequence number. Simply stamp 1, 2, 3, 4 (opening sequence) with a steel seal, and open the circuit in this order or close it in the order of 4, 3, 2, 1.
