Safety Considerations
Read this section carefully before use and be sure to follow the instructions.
Installation, inspection, maintenance, repairs, disassembly, adjustment and valve
opening/closing should be carried out only by trained maintenance personnel.
The precautions listed in this manual are designed to ensure safety and prevent
equipment damage and personal injury. For situations that may occur as a result of
erroneous handling, three different types of cautionary items are used to indicate
the degree of urgency and the scale of potential damage and danger: DANGER,
WARNING and CAUTION.
The three types of cautionary items above are very important for safety: be sure to
observe all of them as they relate to installation, use, maintenance, and repair.
Furthermore, TLV accepts no responsibility for any accidents or damage occurring
as a result of failure to observe these precautions.
Symbols
Indicates a DANGER, WARNING or CAUTION item.
Indicates an urgent situation which poses a threat of death or
serious injury
Indicates that there is a potential threat of death or serious injury
such as electrical shock, fire (burns), etc.
Indicates that there is a possibility of injury or equipment/product
damage
To prevent injury to persons, damage to the instrument and the
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 the instrument and the
equipment.
This instrument must be used in accordance with the
specifications to prevent fire or damage to the instrument and
the 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.
TLV is not responsible if this instrument is repaired, modified or
disassembled by non-factory-approved personnel. Malfunction
may 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 plant.)
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 of 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 to operating personnel.
All precautions described in this manual should be taken to
avoid damage to the instrument or equipment.
If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired.
All wiring must be in accordance with local codes and regulations.
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 a fuse, circuit breaker, etc.
A malfunction in this product may occasionally make control
operations impossible or prevent alarm outputs, resulting in a
possible hazard. Take appropriate measures in the end use to
prevent hazards in the event of malfunction.
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 dissipation.
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 may occur. Use a soft,
dry cloth to remove stains from the instrument.
To avoid damage to the instrument display, do not rub with an
abrasive material or push the front panel with a hard object.

Screens used in this manual
The SC-F71 has two inputs. Following input type is available by setting parameters:
Dual PV (PV + PV) type or PV + Remove setting type. The input type is set to PV +
Remote setting type when shipped from the factory.
For a dual input model, the same parameter may exist in both Input 1 and Input 2.
“1.” or “2.” is added to the top of the parameters for identification. “1.” is not added to
the top of the parameters list for the single input type.
Display example of the dual input type:
Input 1_Set value (SV)
Input 2_Set value (SV)
Display example of a single input type:
Set value (SV)
This manual uses the dual inputs for explanation. For other types such as a single
input type, ignore the first character “1.” at the top of the parameter.
The parameters used only for the dual input type are displayed in the colored
background ( ).
Notation in this manual:
Input 1_Set value (SV)
Input 2_Set value (SV)
In 2. Selecting Parameters, two types of frames are used to distinguish different
parameter conditions as follows.
