G9SX-LM
Precautions for Safe Use
1. Use G9SX-LM@ within an enclosure with IP54 protection or higher
of IEC/EN60529.
2. Incorrect wiring may lead to loss of safety function. Wire
conductors correctly and verify the operation of G9SX-LM@ before
commissioning the system in which G9SX-LM@ is incorporated.
3. Do not apply DC voltages exceeding the rated voltages, or any AC
voltages to the G9SX-LM@ power supply input.
4. Use DC supply satisfying requirements below to prevent electric
shock.
• DC power supply with double or reinforced insulation, for
example, according to IEC/EN60950 or EN50178 or a
transformer according to IEC/EN61558.
• DC supply satisfies the requirement for class 2 circuits or limited
voltage/current circuit stated in UL 508.
5. Apply properly specified voltages to G9SX-LM@ inputs.
Applying inappropriate voltages cause G9SX-LM@ to fail to
perform its specified function, which leads to the loss of safety
functions or damages to G9SX-LM@.
6. Be sure to correctly connect safety input devices to safety input
and enabling input to ensure proper operation of the safety
function.
7. The auxiliary error output, auxiliary monitoring output are NOT
safety outputs.
Do not use auxiliary outputs as any safety output. Such incorrect
use causes loss of safety function of G9SX-LM@ and its relevant
system. Also Logical connection outputs can be used only for
logical connections between G9SXs.
8. After installation of G9SX-LM@, qualified personnel should
confirm the installation, and should conduct test operations and
maintenance. The qualified personnel should be qualified and
authorized to secure the safety on each phases of design,
installation, running, maintenance and disposal of system.
9. A person in charge, who is familiar to the machine in which G9SX-
LM@ is to be installed, should conduct and verify the installation.
10.Mode selector switch should be operated only by qualified
personnel who is familiar to the machine. For example to avoid
unauthorized personnel's unexpected operation of mode selector
switch, use a selector switch with locking-key. The machine should
be stopped before the Mode selector inputs are switched.
11.Perform daily and 6-month inspections for the G9SX-LM@.
Otherwise, the system may fail to work properly, resulting in
serious injury.
12.Do not dismantle, repair, or modify G9SX-LM@. It may lead to loss
of its safety functions.
13.Conformity to IEC/EN 61508 SIL3, IEC/EN62061 SIL3 and
ISO13849-1 PLd was assessed with G9SX-LM@ alone. And
conformity to EN954-1 Safety Category 3 was assessed with
G9SX-LM@ set up with specified proximity sensors. Use only
appropriate components or devices complying with relevant safety
standards corresponding to the required level of safety categories.
Conformity to requirements of safety category is determined as an
entire system. It is recommended to consult a certification body
regarding assessment of conformity to the required safety level.
14.OMRON shall not be responsible for conformity with any safety
standards regarding to customer's entire system.
15.Disconnect G9SX-LM@ from power supply when wiring. Devices
connected to G9SX-LM@ may operate unexpectedly.
16.Be cautious not to have your fingers caught when attaching
terminal sockets to the plugs on G9SX-LM@.
17.Do not use in combustible gases or explosive gases.
18.Proximity sensors to be used should be selected based on the
max. number of revolutions during normal operation and the
number of cogwheel teeth. Please refer to the equation below;
R x 1/60 x N < F
R : Max. number of revolutions during normal operation (rpm)
N : Number of cogwheel teeth
F : Response frequency of Proximity Sensor (Hz)
