Safety Instructions
This document describes the safety instructions for the operation of the TD-260T. Before operating the product, read this document
carefully to familiarize yourself with the product.
Warning Follow the instructions below to avoid risk of serious personal injury and death.
Never use beyond the rated specications as there is a danger of property damage, injury, re or electrical shock.
Never use in ammable gaseous environments including the following locations as there is a danger of explosion.
• Locations subject to corrosive or ammable gases
• Locations subject to water, oil or chemical splash
If the product malfunctions (any smoke, odor or noise is present), stop operating the product immediately and unplug the
power cord as there is a danger of re or electrical shock.
Never attempt to disassemble the product.
Carefully check connections and wiring before applying power.
Be sure to ground the product (with ground resistance of 100 Ω or less).
The electric shock protection class of this product is Class I. The product must be grounded to the protective ground terminal for
protection against electric shock.
To allow the operator to immediately shut o the power to the product, install a switch or circuit breaker that complies with both
IEC60947-1 and IEC60947-3 requirements near the product. The switch or breaker installed must also indicate that it functions to
shut o the power to the TD-260T.
Double insulation or reinforced insulation must be provided between the TD-260T and an external device connected to it and
between the external device and its power source.
Caution Follow the instructions below to avoid risk of personal injury or property damage.
Disconnect the power cord when performing the following.
• Attaching or detaching optional connectors
• Wiring or connecting cables to terminal blocks
• Connecting the ground line
Wait for at least ve seconds between turning on and o.
Never touch the rear panel or connectors while the product is turned on.
When connecting to the signal I/O connector, check the signal name and the pin assignment to prevent a false connection. Be
sure to shut o the power to the product as well when making a connection.
Use a shielded cable when connecting to a load-cell, external I/O or option.
Take adequate measures when operating in the following locations.
• Near a power line
• Where a strong electric or magnetic eld is present
• Where static electricity or noise such as from a relay is generated
Do not install under the following environments.
• Locations subject to temperatures exceeding the specied temperature and humidity ranges
• Locations with high salt or iron content
• Locations under direct vibration or shock
• Outdoor, or locations with an altitude of higher than 2,000 m
Do not operate a damaged unit.
The TD-260T is classied as an open-type (built-in) device and must be installed inside a control panel.
If the top cover and the panel are dirty, wipe them with a soft cloth lightly dampened with a solution of a neutral detergent and
water, and then wipe them again with a damp, well wrung-out cloth. DO NOT use a chemically treated dust cloth, paint thinner,
or other ammable solvents. Using any of them could damage the coating of the product.
If the product is used in a manner unintended by the manufacturer, the product safety may be adversely aected.

1Numeric display
The TD-260T shows a continuous reading or a set value on
the display.
If the sensor input is erroneous or a reading cannot be
displayed, the corresponding overow message is displayed
as shown below.
-LOAD: A/D converter overflow in the negative
direction
LOAD: A/D converter overflow in the positive direction
-Full: Display overflow, lower than -19999
Full: Display overflow, higher than 99999
2Decision output LEDs
The following LEDs show statuses of the TD-260T.
HH/HI
The HH/HI LED shows the operation of the decision
output for the High-High limit (“HH”) or High limit (“HI”),
meaning that the LED displays one of the following
solid colors when a displayed reading is higher than the
corresponding set value.
Red: shows that the HH decision output is ON.
HH value < displayed reading
Orange: shows that the Hi decision output is ON.
HI value < displayed reading
Note that the light displays solid red when the
setting for Enable HH and LL (F1-5) is OFF
OK
The OK LED shows the operation of the OK decision
output, meaning that the LED displays solid green when
a displayed reading is both higher than the LO value and
lower than the HI value.
Green: shows that the OK decision output is ON.
LO value displayed reading HI value
LL/LO
The LL/LO LED shows the operation of the decision output
for the Low-Low limit (“LL”) or Low limit (“LO”), meaning
that the LED displays one of the following solid colors
when a displayed reading is lower than the corresponding
set value.
Red: shows that the LL decision output is ON.
Displayed reading < LL value
Orange: shows that the LO decision output is ON.
Displayed reading < LO value
Note that this LED displays solid red when the
setting for Enable HH and LL (F1-5) is OFF.
NOTE
The operations of decision outputs vary depending on
the settings for Comparative Output Pattern (F1-15) and
Hysteresis (F1-6).
In the above examples, “standard” for Comparative Output
Pattern and “0” for Hysteresis are selected.
3Decision LED (JUDGE)
The LED lights when the decision output is enabled.
With Enable JUDGE Signal (F3-8) set to ON;
the LED lights if the JUDGE signal from A6 is ON, or
the LED remains off if the JUDGE signal from A6 is OFF.
With Enable JUDGE Signal (F3-8) set to OFF,
the LED lights and remains on.

Calibration keys
GAIN: To perform a calibration by applying an actual
load, press this key.
TEDS: To perform a calibration when a TEDS sensor is
connected, press this key.
CAL: To perform a calibration by entering the rated
output values, press this key.
5Lock LEDs
CAL: Lights while changing calibration values is not
allowed.
SET: Lights while changing set values is not allowed.
6Hold-mode LEDs
Each LED displays solid green, showing that the
corresponding mode is set, or it displays solid red or orange,
showing that the TD-260T is operating in the corresponding
mode.
PEAK: Lights when the TD-260T is operating in the
Peak-hold mode.
BOTTOM: Lights when the TD-260T is operating in the
Bottom-hold mode.
P-P: Lights when the TD-260T is operating in the
Peak-to-Peak hold mode.
SAMPLE: Lights when the TD-260T is operating in the
Sample hold mode.

HOLD key
Pressing this key starts the hold operation. To stop the hold
operation, press the key again.

8Set keys
FNC: Pressing this key while a reading is displayed
changes the display to the setup screen.
Each time you press the key while the setup
screen is displayed, the display cycles through
the function numbers.
Pressing the key while the setup screen is
displayed with a digit of the set value blinking
changes the sign setting or the decimal point
position.
ESC/CLEAR: Pressing this key while the setup screen is
displayed cancels the setting, and then displays
a reading again.
Pressing the key while the TD-260T is in a hold
mode clears the hold value.
ENTER: Pressing this key saves the item or value you
have set. Pressing and holding the key while
a reading is displayed disables or enables all
the keys on the TD-260T. While all the keys are
disabled, the key input is disabled, except the
ENTER key that can enable all the keys again by
being pressed and held.
5b: Pressing these keys selects an item you want to
set or changes a set value.
gt: Pressing these keys selects a digit you want to
make changes to.
9
ZERO key
The operation of this key varies depending on the setting
for CAL Lock (F3-5).
Pressing this key performs zero-point calibration while the
calibration lock setting is OFF.
Pressing this key while the calibration lock setting is ON
forces a reading on the display to be zero .
