Product-specific cautions
Use/maintenance
■
Output accuracy is affected by temperature
characteristics and heat generated when
energized. Provide sufficient stand-by time (10
minutes or more after energizing) before use.
■
Clear each Process Data OUT to "0" before
powering this product. Gas may flow
unintentionally.
■
The settings of this product can be changed in two
ways: IO-Link communication from the master and
key input on the device (the product itself). There is
no hierarchical relationship or priority given to
either side, instead the most recently applied
setting is reflected as the setting of this product.
When settings are made on the device side, the
master side is also synchronized. However, note
that some masters may not reflect the new settings
in the display unless the display is updated or
settings are uploaded.
■
Process Data OUT values can only be operated by
the master. Even if a setting is changed via key
operation on a device, these changes will not be
reflected on Process Data OUT values. Check the
Process Data IN / Parameter settings to check the
product setting status on the master side.
■
The "start/stop" bit of Process Data OUT has the
same role as "Flow control/Forced OFF" status
switched by key operation, but the "start/stop" bit is
"1 (Start)". Consequently, the "start/stop" bits of
Process Data OUT remain as "1 (Start)" even if the
flow control → forced OFF is switched by key input
on the device side.
When the "start/stop" bit of Process Data IN is "0
(Stop)", the product will be in the forced OFF state.
When switching the "start (flow control)" state from
the master in this state, set it to "0 (stop)" and then
set it to "1 (start)" again.
■
This product uses a micro-sensor chip, and must
be installed where it will not be subject to dropping,
impact or vibration. Treat the product as a precision
component during installation and transportation.
■
If a problem occurs during operation, immediately
turn the power OFF, stop use, and contact your
dealer.
■
Immediately after power is turned ON, the product
does not start flow rate control operation for
approx. 2 seconds to complete self-diagnosis.
Provide a control circuit/program that ignores
signals for at least two seconds after power is
turned ON.
■
Keep this product's flow rate within the rated flow
range.
■
Use this product within the working pressure
differential.
■
When changing the setting value, turn OFF the
equipment first in order to prevent unexpected
operation of the control system.
■
Do not disassemble or modify this product. Doing
so could result in faults.
■
The case is made of resin. Do not use solvent,
alcohol or detergent in cleaning, since the resin
could absorb it. There is a risk of affecting the
resin. Wipe off dirt with a rag soaked in a diluted
neutral detergent solution and wrung out well.
■
Pay attention to surge current flow-around.
■
The accuracy may vary from the initial status
depending on the working environment or working
conditions.
It is recommended to check the operation of the
product periodically.
■
The sensor chip will degrade when used for long
periods and cause the detected flow rate to
fluctuate. Periodically inspect the sensor chip.
