Maintenance
Warning
1. Perform the following maintenance periodi-
cally in order to prevent possible danger due
to unexpected auto switch malfunction.
1) Securely tighten switch mounting screws.
If screws become loose or the mounting position is
dislocated, retighten them after re-adjusting the mounting
position.
2) Confirm that there is no damage to the lead wires.
To prevent faulty insulation, replace switches or repair lead
wires, etc., if damage is discovered.
3) Confirm that the green light on the 2-color display type
switch is illuminated.
Confirm that the green LED is turned ON when stopped at
the set position. If the red LED is turned ON, when stopped
at the set position, the mounting position is not appropriate.
Re-adjust the mounting position until the green LED is illu-
minated.
2. Perform maintenance inspection according
to the procedure indicated in the instruction
manual.
Improper handling and maintenance may cause damage to
human beings and malfunctioning and damage of machinery
or equipment to occur.
3.
Removal of components, and supply/ex-
haust of compressed air.
When the equipment is removed, first check measures to pre-
vent dropping of driven objects and run away of the equip-
ment, etc. Then, cut off the supply pressure and electric
power, and exhaust all compressed air from the system.
When the machinery is restarted, proceed with caution after
confirming measures to prevent a cylinder from lurching.
Caution
1. Avoid accumulation of iron debris or close
contact with magnetic substances.
The auto switches in an actuator may malfunction when a
large accumulated amount of machining chips, welding spatter
and or magnetically attracted material is located near the auto
switch. This failure may be the result of loss magnetic force
inside of the actuator.
2. Please consult with SMC concerning water
resistance, elasticity of lead wires, usage at
welding sites, etc.
3. Do not use in direct sunlight.
4. Do not mount the product in locations where
it is exposed to radiant heat.
