Product-specic cautions
CAUTION
CAUTION
CAUTION
■
Install a pneumatic lter just before the pneumatic
component in the circuit.
■
When supplying compressed air after connecting
pipes, do not suddenly apply high pressure.
●
The pipe connection could dislocate, causing the pipe
tube to y out, leading to accidents.
■
Air quality
●
Use CKD clean air system components appropriate for
your application.
●
Use compressed air that does not contain oil oxides, tar,
carbon, etc., from the air compressor.
●
Use compressed air that does not contain solid foreign
matter.
●
Install a lter, air dryer, and oil mist lter on the primary
side (upstream side) of the sensor. The sensor's rectier
(mesh) recties the ow in the pipe. It does not lter out
foreign matter, so provide a lter.
Use/maintenance
1. When using the product
2. Maintenance and inspection
■
Do not apply excessive rotational force to the
display.
The display rotates 270 degrees; turn it to your
most convenient position. However, forcing the
display to turn by using excessive force can cause
the stopper to break.
■
Before conducting maintenance, turn the power
OFF, stop the supply of compressed air and make
sure that there is no residual pressure.
●
Observe the conditions to ensure safety.
■
Regularly inspect the product at least once a year
to check that it operates correctly.
■
Do not disassemble or modify, as this may cause
malfunction.
■
When suddenly opening the valve that connects to the sensor, uid
with a ow rate dozens of times greater than the rated ow rate may
ow, and this can cause damage to the platinum thin lm sensor or
rectier and ow out to the secondary side. When opening the valve
that connects to the sensor, open it slowly so that the value in the
monitor display may not exceed the rated ow rate.
■
If a problem occurs during operation, immediately turn
the power OFF, stop use, and contact your dealer.
The display may become warm (approximately
40°C), but this is not an abnormality.
■
After the power supply is turned ON, internal
settings such as hardware check are performed for
10 seconds. During this time, the display/output
cannot operate normally. Particularly, if a switch
output is used in the control of an interlock circuit,
an abnormal stop may occur. Mask the output
during this period.
■
When changing the output set value, turn OFF the
equipment rst in order to prevent unexpected
operation in the control system equipment.
■
If this product is used in an interlock circuit, provide
multiple interlock circuits as a precaution against
failure, and also perform regular inspections to
conrm normal operation.
■
Make sure that no force is applied to the resin parts
when piping.
