after the power supply is turned off.
Electric shock can result.
Caution
1. Maintenance should be performed according to the procedure indicated in the Operating
Manual.
Incorrect handling can cause injury, damage or malfunction of equipment and machinery.
2. Removal of product.
When equipment is serviced, first confirm that measures are in place to prevent dropping of work
pieces and run-away of equipment, etc, then cut the power supply to the system. When machinery is
restarted, check that operation is normal with electric actuators in the proper positions.
3. Remove the actuator cable when manually operating the actuator slider.
If the slider is moved manually while the electric actuator is connected to the driver, a motor-induced
voltage will enter the driver to prevent the slider from moving smoothly. If the slider is frequently moved
manually, the driver may be damaged due to this induced voltage.
[Lubrication]
Caution
1. The product has been lubricated for life at the manufacturer's and does not require lubrication
in service.
Contact SMC if lubrication will be applied.
14.6 Precautions for electric actuator with lock
Warning
1. Do not use the lock as a safety lock or a control that requires a locking force.
The lock used for the product with a lock is designed to prevent dropping of work piece.
2. For vertical mounting, use the product with a lock.
If the product is not equipped with a lock, the product will move and drop the work piece when the
power is removed.
3. "Measures against drops” means preventing a work piece from dropping due to its weight
when the product operation is stopped and the power supply is turned off.
4. Do not apply an impact load or strong vibration while the lock is activated.
If an external impact load or strong vibration is applied to the product, the lock will lose it’s holding
force and damage to the sliding part of the lock or reduced lifetime can result. The same situations
will happen when the lock slips due to a force over the thurst of the product, as this accelerates the
wear to the lock.
5. Do not apply liquid or oil and grease to the lock or its surrounding.
When liquid or oil and grease is applied to the sliding part of the lock, its holding force will reduce
significantly.
6. Take measures against drop and check that safety is assured before mounting, adjustment
and inspection 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 electric actuator is operated manually (when 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, wear 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 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
