KEYENCE has confirmed that the GL-T11R complies with the require-
ments of EC Directives under the conditions that the following require-
ments are satisfied. Note the following requirements when using the
GL-T11R in EU countries.
● EMC Directive (2004/108/EC)

uct Service GmbH.
• Applicable standards
EN61496-1, Type 4 ESPD

■ Other applicable standards
The GL-T11R has been designed in consideration of the following stan-
dards and regulations. For details regarding the following standards, con-
tact the third-party certification organization, such as UL or TÜV.
• EN60204-1
•EN692
•EN693
• OSHA 29 CFR 1910.212
• OSHA 29 CFR 1910.217
• ANSI B11.1 - B.11.19
• ANSI/RIA R15.06 - 1999
• SEMI S2
• "Guidelines for Comprehensive Safety Standards of Machinery", July 31,
2007, number 0731001 issued by Ministry of Health, Labor, and Welfare
in Japan.
DANGER
• The machine on which the GL-T11R is to be installed must be
susceptible to an emergency stop at all operating points dur-
ing its operation cycle. Do not use the GL-T11R for machines
with irregular stop times.
• Do not use the GL-T11R for power presses equipped with full-
revolution clutches.
• The GL-T11R cannot be used as a PSDI because it does not
fulfill the requirements of OSHA 1910.217(h). Refer to OSHA
1910.217 for the PSDI mode.
• Do not use the GL-T11R to control (stop forward motion, etc.)
trains, cars and other transportation vehicles, aircraft, equip-
ment for use in space, medical devices, or nuclear power gen-
eration systems.
DANGER
• Always turn off the power to the GL-T11R when performing
electrical wiring.
• You must fulfill the electrical standards and regulations in the
country or region in which the GL-T11R is being used when
you perform the electrical wiring.
• Wiring shall be in accordance with IEC60204-1/EN60204-1 so
that short-circuit between adjacent terminals is to be pre-
vented.
• To avoid the risk of electric shock, do not connect any of the
GL-T11R inputs/outputs, except for the FSD, to DC power
sources outside of the range of 24 V DC + 10% or to any AC
power source.
• To avoid the risk of electric shock, be sure that the hazardous
voltage is isolated from all wiring of the GL-T11R with rein-
forced insulation or double insulation, except for the FSD.
• In order to fulfill the requirements in IEC61496-1, UL61496-1,
EN61496-1, UL508 and CAN/CSA-C22.2 No. 14, the power sup-
ply for the GL-T11R must fulfill the conditions listed below.
(a)The rated output voltage of 24 V DC (SELV, Overvoltage
Category ) within ± 10%
(b)Double insulation or reinforced insulation between the
primary and secondary circuits.
(c)Output holding time of 20 ms or more.
(d)A power supply must fulfill the requirements of the electrical
safety and electromagnetic compatibility (EMC) regulations
or standards in all countries and/or regions where the
GL-T11R is used.
(e)A secondary circuit of power supply (output) must fulfill the
requirements for Class 2 Circuits or Limited Voltage/Current
Circuits specified in UL508 and CAN/CSA-C22.2 No. 14 if the
GL-T11R is used in the United States or Canada.
• Do not install the electric wiring of the GL-T11R together with
or in parallel with high-voltage electrical or power lines.
• Both of the two FSDs provided on the GL-T11R must be used
to establish a safety related machine control system. Estab-
lishing a safety related machine control system with just one
of the FSDs cannot stop the machine in the event of an FSD
failure and may result in significant harm to the machine oper-
ators including serious injury or death.
• The AUX output, error output, muting state output, alert output,
Clear/Blocked state output and inter-lock-reset-ready output
cannot be used as safety outputs for the safety related control
systems. Usage of these functions as safety outputs may
result in significant harm to the machine operators, including
serious injury or death.
• The wait input is not allowed to be connected to the output
from any components comprising a part of the safety related
machine control system. If the wait input is connected to the
output of a safety component it may result in significant harm
to the machine operators, including serious injury or death.
• Use the GL transmitter cable and receiver cable connected to
the GL-T11R with the length specified in this instruction man-
ual or shorter. Usage of cables longer than the specified length
may cause improper operation of safety functions and may
cause a dangerous situation.
• For connection between GL-T11R and GL, make sure to use
the dedicated cable for GL-T11R for correct connection. If
using a wrong cable or connecting cables for the transmitter
and receiver wrongly, FSD may be always ON. This is danger-
ous.
DANGER
• You must always perform the pre-check test, in accordance
with the pre-check test procedures, after maintenance, adjust-
ment or alignment of the target machine or the GL-T11R and
before the machine startup.
• If the GL-T11R does not operate properly when you perform
the pre-check test according to the pre-check test procedures
specified in this instruction manual, do not operate the
machine.
• You must periodically examine the machine to verify that all
brakes, other stop mechanisms, and control devices operate
reliably and correctly in addition to checking the GL-T11R.
• The responsible personnel must perform maintenance proce-
dures as specified in this instruction manual to avoid any haz-
ardous situation.
• If the GL is in an error condition with the EDM error, the relay
inside the GL-T11R may have a fault. In this case, replace the
relay board according to "Replacing the relay board" of page 6.
