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 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 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.
(7) When the electric actuator is operated manually (when SVRE output signal is off), supply 24 VDC
to the [LK RLS] terminal of the power supply connector.
If the product is operated without releasing the lock, wearing of the lock sliding surface will be
accelerated, causing reduction in the holding force and the life of the locking mechanism.
(8) Do not supply 24 VDC power supply constantly to the [LK RLS (Lock release)] terminal.
Stop supplying 24 VDC power supply to the [LK RLS (Lock release)
]
terminal during normal operation. If
power is supplied to the [LK RLS] terminal continuously, the lock will be released, and work pieces may
be dropped at stop (EMG).
/Refer to the operation manual of LEC (controller) for details of wiring.
