LT Series User Manual 5

Preface

This user manual contains a variety of safety markings for safe and correct opera-

tion of the LT unit. Please read this and any related manuals carefully to fully

understand the correct and safe usage of the LT and its features.

Safety Symbols

Please pay attention to the following safety symbols and their meanings:

Indicates situations that will definitely

result in severe bodily injury, death, or

major machine damage if the instructions

are not followed.

Indicates situations that may result in severe

bodily injury, death, or major machine

damage if the instructions are not followed.

Indicates situations that may result in minor

bodily injury or damage to the machinery if

the instructions are not followed.

DANGER

WARNING

CAUTION

Essential Safety Precautions

When Designing your LT System:

• Be sure to design your LT control system so that, in the

event of a main power supply failure or an LT accident, the

user system’s overall safety integrity will be maintained. If

this is not done, incorrect output signals or an LT malfunc-

tion may cause an accident.

(1) Interlock and other circuits designed to interrupt or op-

pose normal machine movement (such as Emergency

Stop, General Protection, and forward and reverse rota-

tion), as well as those designed to prevent machine dam-

age (such as upper, lower, and traverse movement limit

positioning) should all be designed to be located out-

side of the LT.

DANGERS

Preface

LT Series User Manual

(2) When the LT generates a “Watchdog Timer Error,” LT

operation will halt. Also, when Errors occur in Input/

Output control areas that the LT cannot detect, unex-

pected movement may occur in those areas. Therefore,

and to prevent unsafe machine movement, a “Failsafe

Circuit” should be created which is completely external

to the LT. Section 3.2.5 – “Installation Cautions”

(3) If a problem arises with an external unit’s relay or tran-

sistor that causes an output (coil) to remain either ON

or OFF, a major accident can occur. To prevent this, be

sure to set up external watchdog circuits that will moni-

tor vital output signals.

• Design a circuit that will supply power to the LT unit’s

I/O unit before starting up the LT. If the LT unit’s internal

program enters RUN mode prior to the I/O unit’s load con-

trol power turning ON, an incorrect output (signal) or mal-

function could cause an accident.

• Design a user program that ensures the safety of the user’s

system, in the event of an LT display or control error, or

either a data transmission error or power failure between

the LT and a connected unit. These types of problems can

lead to an incorrect output (signal) or malfunction, result-

ing in an accident.

• Do NOT use the LT as a warning device for critical alarms

that can cause serious operator injury, machine damage,

or production stoppage. Use stand-alone hardware and/or

mechanical interlocks to design alarm indicators and their

control/activator units.

• Do NOT use LT touch panel switches to perform operator

safety-related or important accident-prevention operations.

These operations should be performed by separate hard-

ware switches to prevent operator injury and machine dam-

age.

DANGERS

LT Series User Manual 7

Preface

• Design your system so that equipment will not malfunction

due to a communication fault between the LT and its host

controller. This is to prevent any possibility of bodily injury

or material damage.

• The LT is not appropriate for use with aircraft control de-

vices, medical life-support equipment, central trunk data

transmission (communication) devices, or nuclear power

control devices, due to their inherent requirements of ex-

tremely high levels of safety and reliability.

• When using the LT with transportation vehicles (trains, cars,

and ships), disaster and crime prevention devices, various

types of safety equipment, and medical devices that are

not life-support related, use redundant and/or failsafe sys-

tem designs to ensure the proper degree of reliability and

safety.

• Unlike the LT unit’s “Standby Mode,” after the LT unit’s back-

light burns out, the touch panel is still active. If the opera-

tor fails to notice that the backlight is burned out and

touches the panel, a potentially dangerous machine opera-

tion error can occur. Your backlight is burned out if:

• your LT is not set to “Standby Mode” and the screen has

gone blank

• your LT is set to “Standby Mode,” but touching the screen

does not cause the display to reappear

To prevent an accidental machine operation error, Pro-face

recommends that you use the LT unit’s “USE TOUCH PANEL

AFTER BACKLIGHT BURNOUT” feature, to automatically

detect a burnout and disable the touch screen.

Section 6.4.3 – “Set Up Touch Panel”

DANGERS

WARNINGS

Preface

LT Series User Manual

Installation Warnings:

• High voltage runs through the LT. To prevent an electrical

shock, do NOT disassemble the LT for any reason other

than to replace the backlight.

• Do NOT modify the LT unit. Doing so may cause a fire or an

electrical shock.

• Do NOT use the LT in an environment where flammable

gases are present. Doing so may cause an explosion.

Wiring Warnings:

• 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.

• After completing any LT wiring work, be sure the terminal

block’s protective plastic cover is reattached. If this cover

is not reattached, an electrical shock could easily occur.

• High voltage runs through the LT. Except for changing the

backlight, do NOT attempt to open the LT, since there is a

possibility of an electrical shock.

• Do NOT use power levels with the LT that are higher or

lower than the LT unit’s specified power range. Doing so

may cause a fire, electrical shock, or LT damage.

• Do NOT operate or store the LT in areas where flammable

gases are present and may cause an explosion.

Operation and Maintenance Warnings:

• NEVER touch a live power terminal. Doing so could cause

an electrical shock or a machine malfunction.

• To prevent an electrical shock, unplug the LT unit’s power

cord before either cleaning the LT or attaching/detaching

the power terminal attachment screws.

• When replacing the LT unit’s backlight, be sure to unplug

the unit’s power cord to prevent an electrical shock, and

wear safety gloves to prevent burns.

WARNINGS

LT Series User Manual 9

Preface

• The LT uses a lithium battery to back up its internal clock

and to control memory data. If the battery is incorrectly re-

placed (reversed positive [+] and negative [-] ends), the bat-

tery may explode. Therefore, Pro-face recommends that you

contact your local LT distributor for instructions before re-

placing or changing the battery.

• Do not attempt to modify the LT unit’s internal parts or wir-

ing in any way, since this may lead to either electrical shock

or fire.

Wiring Layout Cautions:

• To prevent an LT unit malfunction due to excessive noise,

isolate all LT input/output signal lines from all power wir-

ing or power cables via a separate wiring duct.

Installation Cautions:

• To reduce the risk of incorrect input or output signals, be

sure that any data cables attached to the LT unit’s connec-

tor make full contact with the connector pins.

General Wiring Cautions

• To prevent electrical shocks or malfunctions, be sure the

LT unit’s FG (earth) wire is grounded as follows:

(1) maximum grounding resistance: 100 ΩΩ

ΩΩ

Ω

(2) minimum grounding wire diameter: 2mm2

• The LT unit’s wiring should be checked to confirm that both

the operating voltage and wiring terminal locations are cor-

rect. If either the voltage or the wiring terminal location is

incorrect, it can cause a fire or accident.

• Be sure to secure all wiring terminal screws with the des-

ignated torque. Screws and terminals that become loose

can cause a short circuit, fire, or accident.
