Precaution on Handling
Use UL approved product for direct current power supply.
1.Clamping voltage current circuit complies with UL508
Circuit which power supply if insulation transducer satisfying
following conditions
Max. voltage (No load) : 30Vrms (42.4V peak) or less
Max. current : (1) 8A or less (Including short circuit)
(2) When limited by the circuit
protector (fuse etc.) with the ratings in the table
below.
Voltage without load (V peak)
0 to 20 [V]
Over 20 [V] up to 30 [V]
Max. current rating (A)
5.0
100/peak voltage
2.Circuit (of class 2) which is of 30Vrms (42.4V peak) or less with the
power supply unit of class 2 complying with L1310 or transducer of
class 2 complying with UL1585.
The Flow Sensor have in after referred to as flow sensor and this
manual contain essential information for the protection of users and
others from possible injury and property damage and to ensure
correct handling.
Please check that you fully understand the definition of the following
messages (signs) before going on to read the text, and always follow
the instructions.
Read this manual and follow its instructions. Signal words such
as WARNING, CAUTION and NOTE, will be followed by
important safety information that must be carefully reviewed.
IMPORTANT MESSAGES
Indicates a potentially hazardous situation
which could result in death or serious injury
if you do not follow instructions.
Gives you helpful information.
Indicates a potentially hazardous situation
which if not avoided, may result in minor
injury or moderate injury.
Do not disassemble, modify (including change of printed circuit
board) or repair.
An injury or failure can result.
Do not operate outside of the specification.
Fire, malfunction or flow sensor damage can result.
Please use it after confirming the specification.
NOTE
Follow the instructions given below when handling the flow sensor.
Otherwise, the flow sensor may be damaged or may fail, thereby
resulting in malfunction.
•Make sure to use a sensor by the specified voltage.
•Make sure to use specified measurement flow and operating pressure.
Perform proper functional checks and leak tests after
maintenance.
Stop operation when an abnormality is observed such that the flow sensor
does not work properly or there is a leakage of fluid. Safety is not be assured
due to unexpected malfunction. When leakage occurred from other parts
except piping, the flow sensor might break. Cut off power supply and stop
supplying pressure. Don’t apply pressure at leaking condition.
To avoid fire and explosion, Do not use the product for
flammable fluid.
This flow sensor is designed for air. Only dry air, N
2
are applicable.
Do not operate in an environment of inflammable, explosive or
corrosive gas.
Fire or an explosion can result.
This flow
sensor is not an explosion proof type.
Do not use this product near by a place where static electricity
is a problem.
Otherwise it can cause failure or malfunction of a system.
These instructions must be followed while in maintenance ;
Turn off the power supply, stop the supplied air, exhaust the
residual pressure and verify the release of air before
performing maintenance.
Otherwise it can cause injury.
