7. Operation for air blowing
This product cannot be operated for air blowing due to the mechanism that switches
the main valve to be fully open after the outlet side’s pressure (P
A
) increase to
approximately 1/2 of the inlet side’s pressure (P
P
).
Caution
1. Leakage voltage
Particularly when using a C-R element (surge voltage suppressor) to protect the
switching element, take note that leakage current will flow through the C-R element,
thus increasing leakage voltage.
AC coil is 8% or less of the rated voltage.
DC coil is 3% or less of the rated voltage.
2. Low temperature operation
Although the valve can be operated at temperature as low as 0
o
C, measure should be
taken 0
o
C to avoid solidifying or freezing drainage and moisture, etc.
Mounting
Warning
1. Opetation manual
Mount and operate the product after reading the manual carefully and understanding
its contents. Also, keep the manual in a place where it can be referred to as necessary.
2. Maintenance space
Allow sufficient space for maintenance and inspection.
3. If air leakage increases or equipment does not operate properly, stop operation.
After mounting or maintenance, etc., connect the compressed air and power supplies,
and perform appropriate function and leakage tests to confirm that the unit is mounted
properly.
4. Painting and coating
Warnings or specifications printed or labeled on a product should not be erased,
removed or covered up.
Furthermore, please contact SMC before painting the resin parts, as this may be cause
adverse effects depending on the solvent.
