SMC Networks PF3A701H Operation Manual page 73

1: The air quality class is according to JIS B 8392-1:2012 [6:6:4] and ISO8573-1:2010 [6:6:4].
Use an air filter with 5 μm or less filtration rating on the inlet side.
2: When using the accumulated value hold function, calculate the product life from the operating conditions, and use the product within
its life. Maximum updating time of accumulated value is 1.5 million times.
If the product is energized for 24 hours per day, the product life will be as follows:
•Data memorized every 5 minutes --- 5 minutes x 1.5 million times = 7.5 million minutes = 14.3 years
•Data memorized every 2 minutes --- 2 minutes x 1.5 million times = 3 million minutes = 5.7 years
If the Accumulated Flow External Reset is repeatedly used, the product life will be shorter than calculated life.
3: Do not release the OUT side piping port of the product directly to the atmosphere without connecting piping. If the product is used
with the piping port released to atmosphere, accuracy may vary.
4: When pipe bore sizes 3/8 (PF3A701H) and 1/2 (PF3A702H) are connected.
5: These values are for modular products with a pipe bore size of 3/8 (PF3A701H), 1/2 (PF3A702H), and supply pressure of 0. 5 MPa.
6: The time from when the flow is changed by a step input (when the flow rate changes from 0 to the maximum flow instantaneously)
until the switch output, turns ON (or OFF) when set at 90% of the rated flow rate.
7: If the applied voltage fluctuates around the set value, the width for setting more than the fluctuating width needs to be set. Otherwise,
chattering will occur.
8: Analogue output or external input can be selected by pressing the buttons. Refer to the graph for analogue output.
9: When selecting 0 to 10V, refer to the analogue output graph for the allowable load current.
10: The time from when the flow is changed as a step input (when the flow rate changes from 0 to the maximum flow instantaneously)
until the analogue output reaches 90% of the rated flow rate.
11: Analogue output or external input can be selected by pressing the buttons.
12: The flow rate given in the specification is the value at standard condition (STD).
13: Setting is only possible for models with the unit selection function.
14: Displayable range change based on the setting of zero cut-off function.
15: The first and next 6 digits (12 digits in total) for accumulated flow rate are displayed. When upper digits are displayed, "x10
up in other window.
16: Anyｓ products with tiny scratches, smears, or display colour variation or brightness which does not affect the performance are
verified as conforming products.
