WARNING
l
Power Supply
Ensure that the instrument’s supply voltage matches the voltage
of the power supply before turning ON the power.
lDo Not Use in an Explosive Atmosphere
Do not operate the instrument in locations with combustible
or explosive gases or steam. Operation in such environments
constitutes an extreme safety hazard. Use of the instrument in
environments with high concentrations of corrosive gas (H2S,
SOX, etc.) for extended periods of time may cause a failure.
lDo Not Remove Internal Unit
The internal unit should not be removed by anyone other than
YOKOGAWA's service personnel. There are dangerous high
voltage parts inside. Additionally, do not replace the fuse by
yourself.
lDamage to the Protective Construction
Operation of the instrument in a manner not specified in the
user’s manual may damage its protective construction.
CAUTION
This instrument is an EMC class A product. In a domestic environ-
ment this product may cause radio interference in which case the
user needs to take adequate measures.

Appropriate
tightening torque:
0.25 N•m
Insert the controller
into the opening at
the front of the panel.
CAUTION
• Tighten the screws with appropriate tightening torque within 0.25
N•m. Otherwise it may cause the case deformation or the bracket
damage.
• Make sure that foreign materials do not enter the inside of the
instrument through the case’s slit holes.

5. How to Connect Wires
WARNING
• Wiring work must be carried out by a person with basic electrical
knowledge and practical experience.
• Be sure to turn OFF the power supply to the controller before
wiring to avoid an electric shock. Use a tester or similar device
to ensure that no power is being supplied to a cable to be
connected.
• As a safety measure, always install a circuit breaker (an IEC
60947-compatible product, 5 A, 100 V or 220 V AC) in an easily
accessible location near the instrument. Moreover, provide
indication that the switch is a device for turning off the power to
the instrument.
• Install the power cable keeping a distance of more than 1 cm
from other signal wires.
• The power cable is required to meet the IEC standards concerned
or the requirements of the area in which the instrument is being
installed.
• Wiring should be installed to conform to NEC (National Electrical
Code: ANSI/NFPA-70) or the wiring construction standards in
countries or regions where wiring will be installed.
• For control relay output, alarm relay output, and power terminal
connections, use heat-resistant cables.
CAUTION
• Provide electricity from a single-phase power supply. If the
power is noisy, install an isolation transformer on the primary
side, and use a line filter on the secondary side. When measures
against noise are taken, do not install the primary and secondary
power cables close to each other.
• If there is a risk of external lightning surges, use a lightning
arrester etc.
• For TC input, use shielded compensating lead wires for wiring.
For RTD input, use shielded wires that have low conductor
resistance and cause no significant differences in resistance
between the three wires.
• Since the control output relay has a life span (resistance load of
100,000 times), use the auxiliary relay to perform ON/OFF control.
• The use of inductance (L) loads such as auxiliary relays, motors
and solenoid valves causes malfunction or relay failure; always
insert a CR filter for use with alternating current or a diode for
use with direct current, as a spark-removal surge suppression
circuit, into the line in parallel with the load.
• After completing the wiring, the terminal cover is recommended
to use for the instrument.

CAUTION
Do not perform auto-tuning for the following processes.
Tune PID manually.
• Processes with fast response such as flow rate control and pres-
sure control.
• Processes which do not allow the output to be turned on and off
even temporarily.
• Processes which prohibit severe output changes at control
valves (or other actuators).
• Processes in which product quality can be adversely affected if
PV values fluctuate beyond their allowable ranges.

This operation guide describes the functions of parameters briefly. The parameter
symbols listed are in the order shown on the display in each group of menu symbols.
In addition, each parameter table has a “User Setting” column, where you can record
your setpoints when setting them in the controller. The scrolling guide is displayed on
