Maintenance And Check - SMC Networks PB1313A Operation Manual

3. Maintenance and check

Warning
(1)The following points must be carefully considered for maintenance
Maintenance shall be performed after obtaining adequate knowledge about the product by
reading this operation manual carefully. Improper handling can cause damage and malfunction
of equipment and machinery.
●When touching the pump for maintenance, wear protective gear such as gloves
which are compatible with the fluid used. There is a risk of chemical burns.
●If the pump is stopped for a few hours, exhaust the air from the AIR SUP port.
●During operation of the pump, it is necessary to check air leakage and operating
conditions regularly. If any abnormality is seen, stop operating the product and
contact your local supplier or SMC sales representative.
(2)Confirm safety before operation
When the product or the supply/exhaust equipment of the pilot air is removed, cut the supply of
compressed air and power, then exhaust compressed air from the system. Discharge or substitute
the residual fluid if necessary. When the equipment is to be started again after remounting or
replacement, first confirm safety, and then confirm that the equipment can operate normally.
(3)Do not disassemble the product. Disassembled product is not guaranteed.
If overhaul is required, contact SMC or the distributor.
(4)Discharging condensate
Operation with condensate caught in the equipment or the piping may lead to operation failure of
the equipment, splashing from the outlet, and unexpected accidents. Remove condensate from
air filters regularly.
Caution
(1)Life of the diaphragm
●When the operation time of the diaphragm exceeds its life, the process pump may be damaged
because the diaphragm is deformed. If the process pump is damaged, the operating fluid will
leak from the pilot air exhaust port and air will get into the fluid circuit. Replace the pump
considering the operating condition of the pump (irregular intake of air, reduction of discharge
pressure) and the reference life of the diaphragm.
[Calculation method of the diaphragm life for reference]
Calculate the life based on the operation frequency of the solenoid valve.
