Pro-face GLC100-LG41-24V User manual

WARNINGS
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 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 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 external to the GLC.
(3) If an 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.
- 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 turning ON, an incorrect output (signal) or malfunction 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 GLC touch panel switches to perform life-related or important accident
prevention operations. These operations should be performed by separate hardware
switches to prevent operator injury and machine damage.
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 terminal block’s protective plas-
tic 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 explosion.
DANGERS

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 un-
plugged 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.
- 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. Therefore, before changing the battery, 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.
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:
- When attaching the I/O unit to the GLC, be sure that all the I/O unit’s attachment
screws are used and the unit is securely attached to the GLC. If the I/O unit is not
attached securely in place, the I/O unit may be damaged if it falls off the back of the
GLC, or a system-related malfunction or accident may occur due to I/O data signal
problems.
- 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
signals can result.
General Wiring Cautions
- To prevent shocks or malfunctions, GLC’s FG (earth) wire should be grounded ac-
cording 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.
- 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 per-
forming program changes, forced output, or utilizing the RUN, STOP or PAUSE
commands while the GLC is in operation. Mistakes concerning the use of these items
can cause a machine accident or damage.
GLC Unit Disposal Cautions
- The GLC unit should be disposed of in a manner appropriate to the user country’s
industrial machinery disposal standards.
