SMC Networks EQFS Series Operation Manual page 8

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 it for vertical application, 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 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 stoke.
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 a day or every 1000 strokes.
Otherwise, lubrication can be lost.
③ Do not use the product in applications where exces- sive external force or impact
force is applied to it.
The product can be damaged. The components, including the motor, are manufactured to
precise tolerances. Even a slight deformation may cause a malfunction or seizure.
④ Refer to the Auto Switches Precautions (Best Pneumatics No②) if an auto switch is to be
built in and used.
⑤ When UL Standards compliance is required, the electric actuator and controller/driver
should be used with a UL1310 class 2 power supply.
⑥ Do not exceed the product specifications even if a work load is supported by
external guides.
Although the actuator moment is reduced by external guides, the required trans- port ability
(the relationship between the speed and the work load) is not reduced.

Mounting
Warning
① nstall and operate the product only after reading the Operation Manual carefully
and understanding its contents. Keep the manual in a safe place future reference.
② Observe the tightening torque for screws.
Tighten the screws to the recommended torque for mounting the product.
③ D o
n o t m a k e a n y a l t e r a t i o n s t o t h i s p r o d u c t .
Alterations made to this product may lead to a loss of durability and damage to the
product, which can lead to human injury and damage to other equipment and machinery.
④ When an external guide is used, connect the moving parts of the product and the
load in such a way that there is no interference at any point within the stroke.
Do not scratch or damage the sliding part by hitting it with an object. Components are
manufactured to precise tolerances, so the slightest deformation may cause faulty operation.
