Before operating your LT unit, be sure to read this manual to familiarize yourself with the LT unit’s operation procedures and features. NOTICE 1. Copying this manual’s contents, either in whole or in part, is prohibited without the express permission of Digital Electronics Corporation, Japan. 2.
Essential Safety Precautions All safety-related procedures stated in this document must be followed to operate the LT correctly and safely. Be sure to read this and any related documents thoroughly to understand the correct operation and functions of the LT unit. Safety Icons Throughout this manual, these icons provide essential safety information for LT operation procedures requiring special attention.
Design a circuit that will supply power to the LT unit’s I/O before starting up the LT. If the LT unit’s internal program enters RUN mode prior to the I/O unit’s load control power turning ON, an incorrect output (signal) or malfunction could cause an accident. Design a user program that ensures the safety of the user’s system, in the event of a LT display or control error, or either a data transmission error or power failure between the LT and a connected unit.
Handling Do not disassemble or modify the LT unit. Doing so may cause a fire or an electric shock. Do not operate the LT in an environment where flammable gases are present, since it may cause an explosion. Wiring To prevent electrical shock or equipment damage, unplug the LT unit’s power cord from the power supply prior to installing or wiring the LT. To prevent an electric shock be sure to disconnect your LT unit’s power cord from the power supply before wiring the LT.
Wiring Be sure to ground the LT unit’s FG wire separately from other equipment FG lines. Also, be sure to use a grounding resistance of 100Ω or less and a 2mm2 [0.0062inch2] or thicker wire, or your country’s applicable standard. Otherwise, electric shock or malfunctions may result. Be sure to use only the designated torque to tighten the LT unit’s terminal block screws. If these screws are not tightened firmly, it may cause a short-circuit, fire or incorrect unit operation.
Do not use paint thinner or organic solvents to remove dirt or oil from the LT unit’s surface. Instead, use a soft cloth moistened with a diluted neutral detergent. Do not use or store the LT in areas with direct sunlight, since the sun’s ultraviolet rays may cause the LCD’s quality to deteriorate. Do not store the LT in an area where the temperature is lower than that recommended in the LT unit’s specifications. Doing so may cause the LCD display’s liquid to congeal, which can damage the LCD.

Chapter 4 Installation and Wiring Connecting the Power Cord • Be sure to remove the connector from the LT unit prior to starting wiring. Failure to do so may cause an electric shock. • The temperature rating of field installed conductors: 75°C only. (1) Confirm that the power cord is unplugged from the power supply. (2) Strip the membrane of the power cord, twist the wire ends, and connect them to the Power Connector (Plug). • Use a flat-blade screwdriver (Size 0.6 X 3.5) to tighten the terminal screws.
LT3000 Series Hardware Manual 4.2.2 Connecting the Power Supply This section describes the precautions for supplying a power voltage. Twisted-pair cord Constant Voltage Transformer • If the supplied voltage exceeds the LT unit’s range, LT FG connect a constant voltage transformer. SEE Chapter 2 Specifications (page 2-1) • For between the line and ground, select a power supply Twisted-pair cord that is low in noise.
Chapter 4 Installation and Wiring 4.2.3 Grounding This section describes the precautions for grounding the LT unit. Do not use common grounding, since it can lead to an accident or machine breakdown. (a) Exclusive Grounding (BEST) LT • When supplying power to the LT unit, be sure to separate the Other Equipment input/output and power lines, as shown. [diagram (a)] • Check that the grounding resistance is 100Ω or less. • FG and SG terminals are internally connected in the LT.
LT3000 Series Hardware Manual 4.2.4 Wiring Precautions To help prevent noise and interference problems, separate all control, communication and power lines by placing them in a separate ducts. Duct for I/O Signal Lines Duct for Control Lines Duct for Power Lines If different wires must be placed in the same duct, separate them with an earthed/grounded divider.
Chapter 4 Installation and Wiring 4.2.5 Installation Precautions External power failure or failure of the LT unit may cause abnormal behavior. To prevent such abnormal behavior from leading to the abnormal operation of the entire system, and to ensure fail-safe operation, configure circuits which may lead to machine damage or accident due to abnormal operation (emergency stop circuit, protection circuit, interlock circuit, etc.) externally to the LT.
LT3000 Series Hardware Manual Emergency Stop Circuit Do not process emergency stop signals with a software program by inputting the signal to the LT. Configure the emergency stop circuit externally to the LT as shown in the figure below: LT 24VDC Output Emergency stop button b (normally closed) contact Input Machine to be controlled Interlock Circuit 1 To use the LT or a PLC to control a motor circuit for forward/reverse rotation, configure the interlock circuit shown below externally to the LT.
Chapter 4 Installation and Wiring • After executing an internal program, the LT outputs ON/OFF information to the output devices at the same time. For example, the electromagnetic switches for forward and reverse rotation of a motor are turned on and off at the same time. Consequently, a situation may arise in which both of the main contacts of the motor circuits for the electromagnetic switches for forward and reverse rotation may turn on, causing a short-circuit of the R and T phases.
LT3000 Series Hardware Manual 4.3 USB Cable Clamp Attachment/Removal This clamp is used to prevent the USB cable connected to the USB Host Interface on the bottom of the LT unit from being unplugged due to vibration or other causes. • When the USB Host Interface is used in the hazardous locations specified in ANSI/ISA-12.12.01, use the USB holder to secure the USB cable.
Chapter 4 Installation and Wiring (3) Insert the USB cable into the USB Host Interface. USB cable (4) Attach the USB cover to the USB host interface.

5 Maintenance 1. Cleaning the Display 2. Periodic Check Points 3. Replacing the Installation Gasket 4. Replacing the Backlight This chapter explains cautions and inspection criteria that will ensure trouble-free use of the LT.
LT3000 Series Hardware Manual 5.1 Cleaning the Display When the surface or frame of the display become dirty, soak a soft cloth in water with a neutral detergent, wring the cloth tightly, and wipe the display. • Do not use paint thinner, organic solvents, or a strong acid compound to clean the unit. • Do not use hard or pointed objects to operate the touch-screen panel, since it can damage the panel surface.
Chapter 5 Maintenance 5.2 Periodic Check Points To keep your LT unit in its best condition, please inspect the following points periodically. LT Operation Environment Is the operating temperature within the allowable range (0ºC to 50ºC)? Is the operating humidity within the specified range (10%RH to 90%RH, dry bulb temperature of 39ºC or less)? Is the operating atmosphere free of corrosive gasses? When using the LT unit inside a panel, the ambient environment refers to the interior of the panel.
LT3000 Series Hardware Manual 5.3 Replacing the Installation Gasket The installation gasket provides protection against dust and moisture. • A gasket which has been used for a long period of time may have scratches or dirt on it, and could have lost much of its water resistance. Be sure to change the gasket at least once a year, or when scratches or dirt become visible. • The LT unit installation gasket’s model number is as follows.
Chapter 5 Maintenance • The gasket must be inserted correctly into the groove for the LT’s moisture resistance to be equivalent to IP65f. • Since the gasket is flexible but not elastic, be careful not to stretch it unnecessarily, as doing so could tear the gasket. • Be sure the gasket’s seam is not inserted into any of the unit’s corners, only in the straight sections of the groove. Inserting it into a corner may lead to its eventually tearing.
LT3000 Series Hardware Manual 5.4 Replacing the Backlight • The LT’s backlight cannot be replaced by the user. When the backlight needs to be replaced, please contact your local LT distributor.
