SYMBOLS
: This mark indicates precautions that must be taken if
there is danger of electric shock, fire, etc., which could
result in loss of life or injury.
: This mark indicates that if these precautions and
operating procedures are not taken, damage to the
instrument may result.
: This mark indicates that all precautions should be taken
for safe usage.
: This mark indicates important information on
installation, handling and operating procedures.
: This mark indicates supplemental information on
installation, handling and operating procedures.
: This mark indicates where additional information may
be located.
To prevent injury to persons, damage to instrument and
equipment, a suitable external protection device shall
be required.
All wiring must be completed before power is turned on
to prevent electric shock, fire or damage to instrument
and equipment.
This instrument must be used in accordance with the
specifications to prevent fire or damage to instrument
and equipment.
This instrument is not intended for use in locations
subject to flammable or explosive gases.
Do not touch high-voltage connections such as power
supply terminals, etc. to avoid electric shock.
RKC is not responsible if this instrument is repaired,
modified or disassembled by other than
factory-approved personnel. Malfunction can occur and
warranty is void under these conditions.
This product is intended for use with industrial machines, test and
measuring equipment. (It is not designed for use with medical
equipment and nuclear energy.)
This is a Class A instrument. In a domestic environment, this
instrument may cause radio interference, in which case the user may
be required to take additional measures.
This instrument is protected from electric shock by reinforced
insulation. Provide reinforced insulation between the wire for the
input signal and the wires for instrument power supply, source of
power and loads.
Be sure to provide an appropriate surge control circuit respectively
for the following:
- If input/output or signal lines within the building are longer than 30
meters.
- If input/output or signal lines leave the building, regardless the
length.
This instrument is designed for installation in an enclosed
instrumentation panel. All high-voltage connections such as power
supply terminals must be enclosed in the instrumentation panel to
avoid electric shock by operating personnel.
All precautions described in this manual should be taken to avoid
damage to the instrument or equipment.
All wiring must be in accordance with local codes and regulations.
All wiring must be completed before power is turned on to prevent
electric shock, instrument failure, or incorrect action. The power must be
turned off before repairing work for input break and output failure
including replacement of sensor, contactor or SSR, and all wiring must
be completed before power is turned on again.
To prevent instrument damage as a result of failure, protect the power
line and the input/output lines from high currents with a suitable
overcurrent protection device with adequate breaking capacity such as
fuse, circuit breaker, etc.
Prevent metal fragments or lead wire scraps from falling inside
instrument case to avoid electric shock, fire or malfunction.
Tighten each terminal screw to the specified torque found in the
manual to avoid electric shock, fire or malfunction.
For proper operation of this instrument, provide adequate ventilation for
heat dispensation.
Do not connect wires to unused terminals as this will interfere with
proper operation of the instrument.
Turn off the power supply before cleaning the instrument.
Do not use a volatile solvent such as paint thinner to clean the instrument.
Deformation or discoloration will occur. Use a soft, dry cloth to remove
stains from the instrument.
To avoid damage to instrument display, do not rub with an abrasive
material or push front panel with a hard object.
The resin adhered to this instrument should be cleaned to dry cloth
with a clean while the resin is still hardened, be careful of burns.
Tools such as wire wheels or abrasive cloths should never be used to
clean the process diaphragm.
Do not apply impact to nor drop this product. If so, its damage or fault
may result.
As precise parts are incorporated, do not give any shock and handle
carefully during transportation and installation. Take great care not to
scratch the diaphragm.
Do not wipe or rub the nameplate on the outer case of the resin
pressure sensor with a cloth moistened with an organic solvent, or a
glove. If so, the printed section may be erased.
This product uses stainless steel, aluminum, and fluororesin (O-rings
and leadwire covering materials). When disposing of each part used
for this product, always follows the procedure for disposing of industrial
wastes stipulated by the respective local community.
If the output from the resin pressure sensor is found to be abnormal
during the operation, immediately stop the operation and inspect for
any distortion or damage of the diaphragm. If the diaphragm is
damaged, the pressure of the measured media (e.g.resin) is applied to
the inside of the resin pressure sensor.
Continued use under such conditions may result in the damage of the
screw which fixes the folder in the housing, and the folder in the
housing may come off in the worst case.
Do not use the pressure sensor in stead of a blind bolt.
