5. Do not apply liquid, oil, or grease to the lock or the area surrounding it.
When liquid, oil, or grease are adhered to the sliding parts of the lock, its holding force will reduce
significantly. Any changes in lock sliding performance and condition may cause a lock release
malfunction.
6. Take measures against drops and check that safety is assured before the mounting,
adjustment, and inspec- tion of the product.
If the lock is released with the product mounted vertically, a work- piece can drop due to its weight.
7. When the actuator is operated manually (when the SVRE output signal is off), supply 24 VDC to
the [BK RLS] terminal of the power supply connector.
If the product is operated without releasing the lock, the wearing of the lock sliding surface will be
accelerated, causing a reduction in the holding force and the life of the locking mechanism.
8.
Do not supply 24 VDC power supply continuously to the [BK RLS (Lock release)] terminal.
Stop supplying 24 VDC power supply to the [BK RLS (Lock release) terminal during normal operation.
If power is supplied to the [BK RLS] terminal continuously, the lock will be released, and workpieces
may be dropped when the stop signal (EMG) is received.
9. The actuator may unable to unlock when the sliding part for locking reaches its life due to the
rotation sliding of the shoe during operation. When the lock mechanism reaches its life, please
contact SMC sales office for the replacement parts.
The sliding part for locking may make noise during operation, but this is normal.
Controller (Including Driver) and Peripheral Devices
2.8 Design/Selection
Warning
1. Be sure to apply the specified voltage.
Otherwise, malfunction or breakage may occur. If the applied volt- age is lower than the specified
voltage, it is possible that the load will not be able to be moved due to an internal voltage drop of the
controller. Please check the operating voltage before use.
2. Do not operate the product beyond the specifications.
Otherwise, a fire, malfunction, or actuator damage may result. Please check the specifications before
use. Install an emergency stop circuit.
3. Please install an emergency stop outside of the enclosure so that the system operation can be
stopped immediately and the power supply can be intercepted.
4. In order to prevent any damage caused by the break- down or malfunction of the controller and
its peripher- al devices, a backup system should be established in advance by giving a
multiple-layered structure or a fail-safe design to the equipment, etc.
5. If a danger of human injury is expected due to abnor- mal heat generation, smoking, ignition,
etc., of the controller and its peripheral devices, cut off the power supply of the product and
the system immediately.
Caution
1. Use an actuator with the lock option if the actuator will not be mounted horizontally for use.
Burnout of the internal parts of the controller may occur. If the actuator is not equipped with a lock, it
will move and drop the workpiece when the power and servo are turned OFF.
2.9 Handling
Warning
1. Do not touch the inside of the controller and its periph- eral devices.
Doing so may cause an electric shock or damage to the controller.
2. Do not perform the operation or setting of the product with wet hands.
Doing so may cause an electric shock.
3. Products with damage or those missing any compo- nents should not be used.
