Description
Thank you for purchasing an SMC PFM5 Series Flow Sensor.
Please read this manual carefully before operating the product and make sure you
understand its capabilities and limitations.
Please keep this manual handy for future reference.
To obtain more detailed information about operating this product,
please refer to the SMC website (URL http://www.smcworld.com) or
contact SMC directly.
These safety instructions are intended to prevent hazardous situations and/or
equipment damage.
These instructions indicate the level of potential hazard with the labels of
"Caution", "Warning" or "Danger". They are all important notes for safety and must
be followed in addition to International standards (ISO/IEC) and other safety
regulations.
Operator
This operation manual is intended for those who have knowledge of machinery
using pneumatic equipment, and have sufficient knowledge of assembly,
operation and maintenace of such equipment. Only those persons are allowed
to perform assembly, operation and maintenance.
Read and understand this operation manual carefully before assembling,
operating or providing maintenance to the product.
Do not operate the product outside of the specifications.
Do not use for flammable or harmful fluids.
Fire, malfunction, or damage to the product can result.
Verify the specifications before use.
Do not disassemble, modify (including changing the printed circuit board) or repair.
An injury or failure can result.
If using the product in an interlocking circuit:
•Provide a double interlocking system, for example a mechanical system.
•Check the product regularly for proper operation.
Otherwise malfunction can result, causing an accident.
The following instructions must be followed during maintenance:
•Turn off the power supply
•Stop the air supply, exhaust the residual pressure and verify that the air is released before performing
maintenance work.
Otherwise an injury can result.
After maintenance is complete, perform appropriate functional inspections and leak tests.
Stop operation if the equipment does not function properly or there is a leakage of fluid.
When leakage occurs from parts other than the piping, the product might be faulty.
Disconnect the power supply and stop the fluid supply.
Do not apply fluid under leaking conditions.
Safety cannot be assured in the case of unexpected malfunction.
Do not touch the terminals and connectors while the power is on.
Otherwise electric shock, malfunction or damage to the product can result.
Warning
Caution
NOTE
The direct current power supply used should be UL approved as follows
Circuit (class 2) of maximum 30Vrms (42.4 V peak) or less, with UL 1310
class 2 power supply unit or UL 1585 class 2 transformer.
The product is a
approved product only if it has a
mark on the body.

Wiring
Wiring of connector
•Connections should only be made with the power supply turned off.
•Use separate routes for the product wiring and any power or high voltage wiring.
Otherwise, malfunction may result due to noise.
•Ensure that the FG terminal is connected to ground when using a commercially
available switch-mode power supply. When a switch-mode power supply is connected
to the product, switching noise will be superimposed and the product specification can
no longer be met. This can be prevented by inserting a noise filter, such as a line noise
filter and ferrite core, between the switch-mode power supply and the product, or by
using a series power supply instead of a switch-mode power supply.

Connecting / Disconnecting
•When mounting the connector, insert it straight into the socket, holding the lever and
connector body, and push the connector until the lever hooks into the housing, and
locks.
•When removing the connector, press down the lever to release the hook from the
housing and pull the connector straight out.

Piping
•Ensure that the metal piping attachments are tightened to the required torque.
(refer to the table below)
•If the tightening torque is exceeded, the product can be broken. If the tightening torque
is insufficient, the fittings may become loose.
•When connecting piping to the product, a spanner should be used on the metal piping
attachment only.
Using a spanner on other parts may damage the product.
•Avoid any sealing tape from entering inside the piping.
•Ensure that there is no leakage from loose piping.

Select response time (input)
The response time can be selected to improve the stability of the analogue output, if the
output is unstable due to flow rate pulsation.
How to select the response time
Connect the response time input wire (white) to GND. While connected, the response
time will be 1.0 second, or 50 ms when not connected.
Do not use the product in a place where static electricity is a problem.
Otherwise it can cause failure or malfunction of the system.
Do not use the product for flammable fluid.
