SMC Networks LE2FS Series Operation Manual page 7

④ Securely tighten all stationary parts and connected parts so that they will not
become loose.
When the product operates with high frequency or is installed where there is a lot of vibration,
ensure that all parts remain secure.
⑤ Consider a possible loss of power source.
Take measures to prevent injury and equipment damage even in the case of a power source failure.
⑥ Consider behavior of emergency stop of whole system.
Design the system so that human injury and/or damage to machinery and equipment will not be
caused when it is stopped by a safety device for abnormal conditions such as a power outage or a
manual emergency stop of whole system.
⑦ Consider the action when operation is restarted after an emergency stop or
abnormal stop of whole system.
Design the system so that human injury or equipment damage will not occur upon restart of
operation of whole system.
⑧ Never disassemble or modify (including additional machining) the product.
An injury or failure can result.
It will cause the loss of the product performance.
⑨ Do not use the stop signal as the emergency stop of the system.
Stop by shutdown of M24V is for stopping the electric actuator with deceleration.
For the emergency stop of the equipment, design the system with a separate emergency stop circuit
conforming to relevant safety standards.
⑩ When using the electric actuator for vertical applications, it is necessary to build
in a safety device.
The rod may fall due to the weight of work. The safety device should not interfere with normal
operation of the machine.
⑪ Do not exceed the product specifications even if a work load is supported by
external guides.
Although the Electric actuator moment is reduced by the external guides, the required trans- port
ability (the relationship between the speed and the work load) is not reduced.
⑫ In order to prevent danger and damage due to the breakdown and the malfunction of
this product, which may occur at a certain probability, a backup system should be
established in advance by giving a multiple-layered structure or a fail-safe design to the
equipment, etc.
⑬ Avoid designing a system that allows the driving part of an electric actuator to operate
with a spring or other external force.
Caution
① Operate within the limits of the maximum usable stroke.
The product will be damaged if it is used with a stroke which exceeds the maximum stroke. Refer to
the specifications of the product.
② When the product repeatedly cycles with partial strokes, operate it at a full stroke at
least once every few 10 strokes.
Otherwise, lubrication can be lost.
