GLC2400/2500/2600 Series User Manual 1
Thank you for purchasing the Pro-face Graphic Logic Controller GLC2400T/
GLC2500T/GLC2600T (hereby referred to as “GLC” or “GLC unit”).
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 GLC2000 Series
without having to purchase and install an optional expansion 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.

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.
This manual includes procedures that must be followed to operate the GLC cor-
rectly and safely. Be sure to read this manual and any related materials thoroughly
to understand the correct operation and functions of the GLC unit.
Safety Symbols
Please pay attention to the following safety symbols and their meanings:
DANGER
WARNING
CAUTION
DANGERS
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 maintained. If
this is not done, incorrect output signals or a GLC mal-
function 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 GLC.
Essential Safety Precautions

GLC2400/2500/2600 Series User Manual 7
Preface
(2) When 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, 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 GLC.
(3) If a 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 moni-
tor vital output signals.
• Design a circuit that will supply power to the GLC unit’s
I/O before starting up the GLC. If the GLC 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 a GLC display or control error, or
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, re-
sulting in an accident.
•Do NOT make switches using the switches on the touch
panels which may cause operator injury and machine dam-
age. An output may remain either ON or OFF and a major
accident can occur. To prevent this, set up circuits such as
limiters that will monitor vital output signals. Design
switches for important operations to be performed by sepa-
rate devices. An incorrect output or malfunction can occur
and thereby cause an accident.
• Do NOT use GLC touch panel switches to perform operator
safety-related or important accident-prevention operations.
These operations should be performed by separate hardware
switches to prevent operator injury and machine damage.
DANGERS

Preface
GLC2400/2500/2600 Series User Manual8
WARNINGS
DANGERS
• Design your system so that equipment will not malfunction
due to a communication fault between the GLC and its host
controller. This is to prevent any possibility of bodily injury
or material damage.
•Do NOT use the GLC as a warning device for critical warn-
ing 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.
• The GLC 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 GLC 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
system designs to ensure proper reliability and safety.
• Unlike the GLC unit’s “Standby Mode,” after the GLC unit’s
backlight burns out, 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
misoperation can occur. Your backlight is burned out if:
• your GLC is not set to “Standby Mode” and the screen
has gone blank
• your GLC is set to “Standby Mode,” but touching the
screen does not cause the display to reappear
To prevent accidental machine misoperation, Pro-face rec-
ommends that you use the GLC unit’s “USE TOUCH PANEL
AFTER BACKLIGHT BURNOUT” feature, to automatically
detect a burnout and disable the touch screen.

Preface
Installation Warnings:
• High voltage runs through the GLC. To prevent an electrical
shock, do NOT disassemble the GLC for any reason other
than to replace the backlight.
• Do NOT modify the GLC unit. Doing so may cause a fire or
an electrical shock.
• Do NOT use the GLC in an environment where flammable
gases are present. Operating the GLC under these condi-
tions may cause an explosion.
Wiring Warnings:
• To prevent electrical shock or equipment damage, unplug
the GLC unit’s power cord from the power supply prior to
installing or wiring the GLC.
• 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 electrical shock could easily
occur.
• Do NOT use power levels with the GLC that are higher or
lower than the GLC unit’s specified power range. Doing so
may cause a fire, electrical shock, or GLC damage.
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 GLC unit’s power
cord before either cleaning the GLC or attaching/detach-
ing the power terminal attachment screws.
• When replacing the GLC unit’s backlight, be sure to un-
plug the unit’s power cord to prevent an electrical shock,
and wear safety gloves to prevent burns.
