13.5 Maintenance
Warning
(1) Do not disassemble or repair the product.
Fire or electric shock can result.
(2) Before modifying or checking the wiring, the voltage should be checked with a tester 5 minutes
after the power supply is turned off.
Electrical 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., and then cut the power supply to the system. When
machinery is restarted, check that operation is normal with the electric actuators in the proper
positions.
(3) When moving the
electric actuator slider manually by hand, please disconnect the electric
actuator cable.
The electric actuator cannot be moved smoothly by the induced voltage of the motor goes to the
controller when the electric actuator slider is moved with the electric actuator connected with the
controller. Moreover, the controller might break down by the induced voltage when moving the electric
actuator slider at high frequency.
[Lubrication]
Caution
(1) The product has been lubricated for life at manufacturer, and does not require lubrication in
service.
Contact SMC if lubrication will be applied.
13.6 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 pr
oduct, 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 drops 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.
