Digital Corporation GLC2400 Manuale utente

Thank you for purchasing Digital Corporation's Pro-face Graphic Logic Controller

GLC2400 (referred as “GLC” from here on).

This controller features a number of improvements over the previous GLC series

including enhanced functions and advanced operability. Flex Network communi-

cation, Ethernet, CF Card and Sound output are available for the GLC2400 with-

out having to purchase and mount an extension unit.

Please read this manual carefully as it explains, step by step, how to use the GLC

correctly and safely.

Also, in this manual's examples, the Mitsubishi MELSEC-AnA Series PLC is

used whenever possible, connected in a one-to-one relationship with a GLC.

INDEX

Preface

GLC2000 Series User Manual

This guide contains a variety of safety markings for safe and correct operation of

this Unit. Please read this installation guide and any related manuals carefully to

fully understand how to correctly use this Unit's functions.

!Safety Symbols

Please pay attention to these symbols and follow all instructions given.

The safety symbols and their meanings are as follows:

Indicates situations where severe bodily

injury, death or major machine damage will

definitely occur.

Indicates situations where severe bodily

injury, death or major machine damage can

possibly occur.

Indicates situations where slight bodily

injury or machine damage can occur.

DANGER

WARNING

CAUTION

Essential Safety Precautions

When Designing your GLC System:

- Be sure to design your GLC control system so that in the

event of a main power supply failure or a GLC accident,

the user system’s overall safety integrity will be main-

tained. If this is not done, incorrect output signals or a

GLC malfunction may cause an accident.

(1) Interlock circuits, etc. designed to interrupt or oppose

normal machine movement (i.e. Emergency Stop, General

Protection, forward and reverse rotation, etc.), as well as

those designed to prevent machine damage (i.e. for up-

per, lower and traverse movement limit positioning, etc.)

should all be designed to be located outside of the GLC.

DANGERS

GLC2000 Series User Manual 7

Preface

DANGERS

(2) Whenever the GLC generates a “Watchdog Timer Error”,

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

Output control areas that the GLC cannot detect, it is

possible for unexpected movement to occur in those

areas. As a result, for the purpose of preventing unsafe

machine movement, a “Failsafe Circuit” should be cre-

ated which is completely external to the GLC.

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

sistor, causing 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 monitor vital

output signals.

- Design a circuit that will supply power to the GLC’s I/O

unit before starting up the GLC. If the GLC’s internal pro-

gram enters RUN mode prior to the I/O unit’s load control

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

function could cause an accident to occur.

- Design a user program that will ensure the safety of the

user’s system, in the event of a GLC display or control

error, or in the event of either a data transmission error or

power failure between the GLC and a connected unit.

These types of problems can lead to an incorrect output

(signal) or malfunction, which could thereby cause an

accident to occur.

- Do not use the GLC unit as a warning device for critical

alarms that can cause serious operator injury, machine

damage or production stoppage. Critical alarm indicators

and their control/activator units must be designed using

stand-alone hardware and/or mechanical interlocks.

- Do NOT use GLC touch panel switches to perform life-

related or important accident prevention operations.

These operations should be performed by separate hard-

ware switches to prevent operator injury and machine

damage.

Preface

GLC2000 Series User Manual

- Please design your system so that equipment will not mal-

function due to a communication fault between the GLC

and its host controller. This is to prevent any possibility

of bodily injury or material damage.

- The GLC is not appropriate for use with aircraft control

devices' or medical life support equipment, central trunk

data transmission (communication) devices, nuclear

power control devices, or medical life support equipment,

due to these devices' inherent requirements of extremely

high levels of safety and reliability.

- When using the GLC with transportation vehicles (trains,

cars and ships), disaster and crime prevention devices,

various types of safety equipment, non-life support re-

lated medical devices, etc. redundant and/or failsafe sys-

tem designs should be used to ensure the proper degree

of reliability and safety.

DANGERS

WARNINGS

- After the GLC's backlight burns out, unlike the GLC's

"Standby Mode", the touch panel is still active. If the

operator fails to notice that the backlight is burned out

and touches the panel, a potentially dangerous machine

missoperation can occur.

1) If your GLC is not set to " Standby Mode" and the screen

has gone blank, your backlight is burned out.

2) Or, if your GLC is set to Standby Mode, but touching the

screen does not cause the display to reappear, your back-

light is burned out.

Also, to prevent accidental machine miss-operation, Digital

suggests you use the GLC's built-in "USE TOUCH PANEL

AFTER BACKLIGHT BURNOUT" feature, that will auto-

matically detect a burnout and disable the touch screen.

GLC2000 Series User Manual 9

Preface

WARNINGS

Installation Warnings:

- High voltage runs through the GLC. Except for replacing

the backlight, never disassemble the GLC, otherwise an

electric shock can occur.

- Do not modify the GLC unit. Doing so may cause a fire or

an electric shock.

- Do not use the GLC in an environment where flammable

gasses are present, since operating the GLC may cause

an explosion.

Wiring Warnings:

- To prevent electric shock or equipment damage, prior to

installing or wiring the GLC, confirm that the GLC’s power

cord is unplugged from the power supply.

- After completing any GLC wiring work, be sure the termi-

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

cover is not reattached, an electric shock could easily

occur.

- High voltage runs through the GLC. Except for changing

the backlight, do NOT attempt to open the GLC, since

there is a possibility of an electric shock.

- Do not use power levels with the GLC that are outside of

the GLC’s specified power range. Doing so may cause a

fire, electric shock or damage the GLC.

- Do not operate or store the GLC in areas where flammable

gasses are present, since operating the GLC may cause

an explosin.

Operation and Maintenance Warnings:

- Never touch a live power terminal. This could cause a

shock or machine malfunction.

- Due to the danger of an electric shock, confirm that the

GLC’s power cord is unplugged before either cleaning the

GLC or attaching/detaching the power terminal screws.

- When replacing the GLC’s backlight, be sure to unplug the

unit’s power cord to prevent a shock, and wear gloves to

prevent being burned.

Preface

GLC2000 Series User Manual

CAUTIONS

WARNINGS

- The GLC uses a lithium battery for backing up its internal

clock and control memory data. If the battery is incor-

rectly replaced (i.e. the + and - sides are reversed), the

battery may explode. Therefore, before changing the bat-

tery, Digital recommends that you contact your local GLC

distributor for battery replacement instructions.

- Do not attempt to modify the GLC’s internal parts or wiring

in any way, since this may lead to either a shock or fire.

Wiring Layout Cautions:

- Be sure that all GLC input/output signal lines are isolated

from all power wiring or power cables, via a separate

wiring duct. This is to prevent excessive noise, which can

cause a unit malfunction.

Installation Cautions:

- Be sure any data cable attached to the GLC’s connector is

securely attached. If the cable and connector pins do not

all make complete contact, incorrect input or output sig-

nals can result.

General Wiring Cautions

- To prevent shocks or malfunctions, GLC’s FG (earth) wire

should be grounded according to the following:

1) A maximum grounding resistance of 100 W or less.

2) A grounding wire of 2mm2or larger should be used.

- The GLC’s wiring should be checked to confirm both that

the operating voltage and wiring terminal locations are

correct. If either the voltage or the wiring terminal loca-

tions are incorrect, it can cause a fire or accident.

- Be sure to secure all wiring terminal screws in place with

the designated torque. Screws and terminals that become

loose can cause a short circuit, fire or accident.
