INSTRUCTION MANUAL
In order to achieve maximum performance and ensure proper operation of
your new instrument, carefully read all the instructions in this manual.
Please place this manual in a convenient location for easy reference.
x An external protection device must be installed if failure of this
instrument could result in damage to the instrument, equipment or
injury to personnel.
x All wiring must be completed before power is turned on to prevent
electric shock, fire or damage to instrument and equipment.
x This instrument must be used in accordance with the specifications
to prevent fire or damage to instrument and equipment.
x This instrument is not intended for use in locations subject to
flammable or explosive gases.
x Do not touch high-voltage connections such as power supply
terminals, etc. to avoid electric shock.
x We are not responsible if this instrument is repaired, modified or
disassembled by other
Malfunction can occur and warranty is void under these conditions.
CAUTION
x 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 adequate measures.
x 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.
x 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.
x 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.
x All precautions described in this manual should be taken to avoid
damage to the instrument or equipment.
x All wiring must be in accordance with local codes and regulations.
x 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.
x To prevent instrument damage of failure, protect the power line and
the input/output lines from high currents with a protection device
such as fuse, circuit breaker, etc.
x Prevent metal fragments or lead wire scraps from falling inside
instrument case to avoid electric shock, fire or malfunction.
x Tighten each terminal screw to the specified torque found in the
manual to avoid electric shock, fire or malfunction.
x For proper operation of this instrument, provide adequate
ventilation for heat dispensation.
x Do not connect wires to unused terminals as this will interfere with
proper operation of the instrument.
x Turn off the power supply before cleaning the instrument.
x 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.
x To avoid damage to instrument display, do not rub with an abrasive
material or push front panel with a hard object.
x Do not connect modular connectors to telephone line.
x This manual assumes that the reader has a fundamental knowledge
of the principles of electricity, process control, computer technology
and communications.
x The figures, diagrams and numeric values used in this manual are
only for purpose of illustration.
x We are not responsible for any damage or injury that is caused as a
result of using this instrument, instrument failure or indirect damage.
x Periodic maintenance is required for safe and proper operation of
this instrument. Some components have a limited service life, or
characteristics that change over time.
x Every effort has been made to ensure accuracy of all information
contained herein. We makes no warranty expressed or implied,
with respect to the accuracy of the information. The information in
this manual is subject to change without prior notice.
