*1 Air quality grade is JIS B 8392-1:2012 [4:6:-] and
ISO 8573-1:2010 [4:6:-].
*2 Set point range will change according to the
setting of the zero cut-off function.
*3 When using the accumulated value hold function,
use the operating conditions to calculate the
product life, and do not exceed it. The maximum
update limit of the memory device is 1.5 million
times. If the product is operated 24 hours per day,
the product life will be as follows:
· 5 min interval: life is calculated as 5 min x 1.5
million = 7.5 million min = 14.3 years
· 2 min interval: life is calculated as 2 min x 1.5
million = 3 million min = 5.7 years
If the accumulated value external reset is
repeatedly used, the product life will be shorter
than the calculated life.
*4 The value when connecting a product with a port
size of 3/8 (PF3A801H) or 1/2 (PF3A802H)
*5 In the low flow rate range, the temperature value
fluctuates (rises). Refer to the "Temperature
Accuracy" graph on page 25.
*6 Do not release the OUT side piping port of the
product to the atmosphere without connecting
piping. If the product is used with the piping port
released to atmosphere, accuracy may vary.
*7 The value when the port size of the modular
product is 3/8 (PF3A801H) or 1/2 (PF3A802H) and
the product is operated at a supply pressure of 0.5
MPa
*8 The time from when the measured value reaches
the set value to when the switch output operates
can be set.
*9 If the measured value fluctuates around the set
value, the width for setting more than the
fluctuating width needs to be set. Otherwise,
chattering will occur.
*10 The flow rate given in the specifications is the
value under standard conditions.
*11 Setting is only possible for models with the units
selection function.
*12 Display range will change according to the setting
of the zero cut-off function.
*13 The time for the digital filter can be set to the
sensor input. The response time indicates when
the set value is 90% in relation to the step input.
*14 The configuration file can be downloaded from
the SMC website, https://www.smcworld.com
*15 The device ID differs according to each product
type (output specification).
* Products with tiny scratches, marks, or display color
or brightness variations which do not affect the
performance of the product are verified as
conforming products.
