2. From the execution of the dedicated instruction: CLOSE to the next execution of dedicated instruction:
OPEN.
(1) Conditions for starting workpiece drop detection
-1. Basic setting- "Status signal output to digital output port" of SMC Air Gripper Unit Configuration Screen is
valid.
-
2.“CLOSE AND CHECK SIGNAL” is selected for the operation of the dedicated instruction: CLOSE.
-
3. Dedicated instruction: CLOSE, “Close position switch” is on.
(2) Conditions for workpiece drop detection
1. After starting the workpiece drop detection, constantly monitor the Close position switch signal.
2. When the monitored Close switch signal is turned off, it is judged as "workpiece drop is detected".
5-4. Air supply
!
Warning
1. Please contact SMC when using the product in applications other than with compressed air.
2. Compressed air containing a large amount of drainage can cause the malfunction of pneumatic
equipment. An air dryer or water separator should be installed upstream from filters.
3. If condensation in the drain bowl is not emptied on a regular basis, the bowl will overflow and allow
the condensation to enter the compressed air lines. This causes the malfunction of pneumatic
equipment. If the drain bowl is difficult to check and remove, the installation of a drain bowl with an
auto drain option is recommended.
4 Use clean air.
Do not use compressed air that contains chemicals, synthetic oils including organic solvents, salt or
corrosive gases, etc., as it can cause damage or malfunction of equipment.
For detailed information regarding the quality of the compressed air described above, refer to
SMC's "Air Cleaning Systems".
!
Caution
1. When dry air is used as the fluid, degradation of the lubrication properties inside the equipment
may occur, resulting in reduced reliability (or reduced service life) of the equipment. Please
consult with SMC.
2. Install air filters.
Install
an air filter at the upstream side of valve. Select an air filter with a filtration degree of 5μm
or finer.
3. Install an aftercooler, air dryer or drain catch before the filter and take appropriate measures.
Compressed air that contains excessive foreign material may cause malfunction of valves and
other pneumatic equipment.
Therefore, take appropriate measures to ensure air quality, such as by providing an aftercooler, air
dryer or water separator.
4. Use the product within the specified fluid and ambient temperature range.
If the fluid temperature is 5
o
C or Cable at the bottom, the moisture in the circuit could freeze,
causing damage to the seals and leading to equipment malfunction. Therefore, take appropriate
measures to prevent freezing.
For detailed information regarding the quality of the compressed air described above, refer to SMC's
"Air Cleaning Systems".
5-5. Piping
!
Caution
1. Refer to the Fittings and Tubing Precautions (Best Pneumatics) for handling one touch fittings.
2. Before piping
Before piping, blow air (flush) or clean the piping to remove any cutting chips, cutting oil, dust, etc.
