Pro-face GLC2500-TC41-24V User manual

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, in-
correct output signals or a GLC malfunction may cause an acci-
dent.
(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 upper, lower and traverse
movement limit positioning, etc.) should all be designed to be
located outside of the GLC.
(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 created which is completely ex-
ternal to the GLC.
(3) If a problem arises with an external unit’s relay or transistor,
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.
- Be sure to design a circuit that will supply power to the GLC’s I/O
unit before starting up the GLC. If the GLC’s internal program
enters RUN mode prior to the I/O unit’s load control power turn-
ing ON, an incorrect output (signal) or malfunction could cause
an accident to occur.
- Be sure to design a 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 be-
tween 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 create GLC touch panel switches that could possibly en-
danger the safety of equipment and personnel. Damage to the
GLC, its I/O unit(s), cable(s), and other related equipment can
cause an output signal to remain continuously ON or OFF and

-16-
- Do not use the GLC unit as a warning device for critical alarms
that can cause serious operator injury, machine damage or pro-
duction stoppage. Critical alarm indicators and their control/acti-
vator units must be designed using stand-alone hardware and/or
mechanical interlocks.
- Do not use GLC touch panel switches to perform operator safety-
related or important accident prevention operations. These op-
erations should be performed by separate hardware switches to
prevent operator injury and machine damage.
- Be sure to 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 transmis-
sion (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 related medical devices, etc.
redundant and/or failsafe system designs should be used to en-
sure the proper degree of reliability and safety.
WARNINGS
Touch Panel 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 no-
tice that the backlight is burned out and touches the panel, a po-
tentially dangerous machine operation error 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 backlight is burned
out.
Also, to prevent an accidental machine operation error, Pro-face
suggests you use the GLC's built-in "USE TOUCH PANEL AFTER
BACKLIGHT BURNOUT" feature, that will automatically detect a
burnout and disable the touch screen.
Installation Warnings:
- High voltage current runs through the GLC. Except for replacing
the backlight, never disassemble the GLC, otherwise an electric
shock can occur.
DANGERS

-17-
- 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 install-
ing or wiring the GLC, confirm that the GLC’s power cord is un-
plugged from the power supply.
- After completing any GLC wiring work, be sure the terminal block’s
protective plastic cover is reattached. If this cover is not reat-
tached, an electric shock could easily occur.
- 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 gas-
ses are present, since operating the GLC may cause an explo-
sion.
Operation and Maintenance Warnings:
- Do not 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 at-
taching/detaching the power terminal block 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.
- The GLC uses a lithium battery for backing up its internal clock
and control memory data. If the battery is incorrectly replaced
(i.e. the + and - sides are reversed), the battery may explode. There-
fore, before changing the battery, Pro-face recommends that you
contact your local GLC distributor for battery replacement instruc-
tions.
- 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.
CAUTIONS
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 a GLC connector is securely
attached. If the cable and connector pins do not all make com-
plete contact, incorrect input or output signals can result.e noise,
which can cause a unit malfunction.

-18-
- The GLC must be used as a built-in component of an end-use
product.
- The GLC should be installed in the front face of a metal panel.
- If the GLC is installed so as to cool itself naturally, be sure to
install it in a vertical panel.
General Wiring Cautions:
- To prevent shocks or malfunctions, the GLC’s FG (earth) wire
should be grounded according to the following:
1) A maximum grounding resistance of 100ΩΩ
ΩΩ
Ωor 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 ei-
ther the voltage or the wiring terminal locations 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.
- Be sure that metal filings or wiring remnants do not fall inside the
GLC, since they can cause a fire, accident, or malfunction.
GLC Operation and Maintenance Cautions:
- Be sure to read the GLC’s manual and on-line help information
carefully before performing program changes, forced output, or
utilizing the RUN, STOP, PAUSE, Enable I/O and other commands
while the GLC is in operation. Mistakes concerning the use of
these items can cause a machine accident or damage.
- The liquid crystal panel contains a powerful irritant and if for any
reason the panel is damaged and this liquid enters your eye, flush
your eye for 15 minutes with running water and contact a physcian.
- Prior to inserting or removing a CF Card, be sure to turn the GLC's
CF Card ACCESS switch OFF and to confirm that the ACCESS
lamp is not lit. If you do not, CF Card internal data may be dam-
aged or lost.
- Do not turn OFF or reset the GLC while a CF Card is being ac-
cessed or insert or remove the CF Card. Prior to performing these
operations, create and use a special GLC application screen that
will prevent access to the CF Card.
GLC Unit Disposal Cautions:
- Be sure to dispose of the GLC unit in a manner appropriate to
your country’s industrial machinery disposal standards.

• Before installing the GLC into a cabinet or panel, check that
the installation gasket is securely attached to the unit.
• 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
dust and drip resistance. Be sure to change the gasket peri-
odically (or when scratches or dirt become visible).


Confirm the Installation Gasket's Positioning
It is strongly recommended that you use the gasket. It absorbs vibration in
addition to repelling moisture.
Place the GLC on a level surface with the display panel facing downward.
Check that the GLC’s installation gasket is seated securely into the gasket’s
groove, which runs around the perimeter of the panel’s frame.

• To avoid a short caused by loose ring terminals, be sure to use ring termi-
nals with an insulating sleeve. *1
• When the FG terminal is connected, be sure the wire is grounded. Not
grounding the GLC unit will result in excess noise and vibration.
• Wherever possible, use thick wires (max. 2 mm2) for power terminals, and
twist the wire ends before attaching the ring terminals.
• Be sure to use the following size ring terminals.
Connecting the GLC Power Cord
When connecting the power cord, be sure to follow the procedures given
below.
1. Confirm that the GLC's Power Cord is unplugged from the power supply.
2. Use a screwdriver to remove the Power Input Terminal Block's clear plastic

•Between the line and the ground, be sure to use a low noise power supply. If
there is still an excessive amount of noise, connect a noise reducing trans-
former.
•Input and Output signal lines must be separated from the power control cables
for operational circuits.
•To increase the noise resistance, be sure to twist the ends of the power cord
wires before connecting it to the GLC unit.
•The GLC's power supply cord should not be bundled with or kept close to
main circuit lines (high voltage, high current), or input/output signal lines.
•Connect a surge absorber to handle power surges.
•To reduce noise, make the power cord as short as possible.
•All GLC Input and Output signal lines must be separated from all operating
circuit (power) cables.
•If this is not possible, use a shielded cable and ground the shield.
