8 DESCRIPTION OF COMPONENTS
9 MAINTENANCE
WARNING:
y Do not dis-assemble the product. A product which has been dis-
assembled cannot be guaranteed. Consult with SMC if dis-assembly is
necessary.
y After installation, repair and dis-assembly, connect compressed air and
perform a proper functional test and leak test. If bleed noise is louder
than the initial state or operation is abnormal, stop operation and check
if installation is correct or not.
CAUTION:
y Check if supply air is clean. Inspect compressed air cleaning system
periodically so that dust, oil and humidity, which can cause malfunction
and failure of the unit, do not enter the equipment.
y If handled improperly, compressed air can be dangerous. Maintenance
and replacement of unit parts should only be performed by trained and
experienced personnel for instrumentation equipment, as well as
following the product specifications.

9 MAINTENANCE (CONTINUED)
y Check the positioner once a year. If excessively worn diaphragms,
O-rings or seals are found, or any unit that has been damaged,
replace with new units. Treatment at an early stage is especially
important if the positioner is used in a place of severe environment like
coastal area.
y Before removing the positioner for maintenance or replacing unit parts
after installation, make sure the supply pressure is shut off and all
residual air pressure is released from piping.
y When the fixed orifice is clogged with carbon particles or others,
remove the pilot valve unit Auto/Manual switch screw (built-in fixed
orifice) and clean it by inserting a f0.2 wire into the aperture. If it must
be replaced with a new one, stop the supply pressure and remove the
stopper screw of the pilot valve unit.
y When disassembling the pilot valve, coat grease on the O-ring of the
sliding section. (Use TORAY SILICONE SH45 grease)
y Check for air leaks from the compressed air piping. Air leaks could
lower the performance characteristics of the positioner. Air is normally
discharged from a bleed port, but this is necessary air consumption
based on the construction of the positioner, and is not an abnormality
if the air consumption is within the specified range.
y When replacing piping to change the operating direction, be sure to
perform span adjustment (parameter code: C70).
y When removing the positioner from the actuator and mounting it onto
another actuator, malfunctions may occur due to its retained initial
constant. Therefore, when it is mounted onto other actuators, transmit
the input current while cutting the air supply, and shift to parameter
mode for adjustments.
y The balance current will change depending on the positioner
orientation. Adjust the balance current (parameter code: C60) every
time the orientation changes.
10 LIMITATIONS OF USE
WARNING:
y Do not exceed any of the specifications laid out in section 2 of this
document or the specific product catalogue.
y Read thoroughly and understand the operation manual before
operation of this product.
