-Solid wire: 0.2 to 2.5mm
2
AWG24 to AWG12
-Stranded wire (Flexible wire):0.2 to 2.5mm
2
AWG24 to AWG12
Strip the cover of wire no longer than 7mm.
2) For model G9SX-LM-RT (with screw terminals)
Tighten each screw with a specified torque of 0.5 to 0.6Nm, or the
G9SX-LMmay malfunction or generate heat.
3) For Logical AND Connection
Use VCTF cable or shielded cable for Logical AND connection
between
units.
(6) When connecting Expansion Units (G9SX-EX-) to G9SX-LM:
1) Follow the procedure below:
a) Remove the termination connector from the receptacle on G9SX-LM.
b) Insert the head of the connecting cable of Expansion Unit to the
receptacle on the G9SX-LM.
c) Set the termination connector to the receptacle on the Expansion Unit at
the end position.When G9SX-LMis used without expansion units, leave
the termination connector set on the G9SX-LM.
2) Do not remove the termination connector while the system is operating.
3) Before applying supply voltage, confirm that the connecting sockets and
plugs are locked firmly.
4) All of the Expansion Units should be supplied with its specified voltages
within 10s after the connected G9SX-LMis supplied with voltage.
Otherwise, G9SX-LMdetects the power-supply error for the Expansion Units.
( 7 ) Use 1NO1NC contact switch as a mode selector switch.
(8) Use cables with length less than 100m to connect to Safety Inputs, Mode
selector input,
Feed-back/Reset inputs, or between Logical AND connection
inputs and Logical connection outputs, respectively.
( 9 ) Use cables with length less than 100m to connect to proximity sensor .
(10) Set the time duration of Low speed monitoring frequency preset to an appropriate
value that does not cause the loss of safety function of system.
(11) Use specified cogwheels to firmly fix proximity sensors so as to prevent the
sensors from dropping off.
(Refer to "8.Shape of Cogwheel and Setting for Proximity Sensors".)
(12) Logical connection between Units:
1) When using Logical AND connection inputs, set the Logical connection
preset switch to 'AND' position for the units which the logical connection
signal are input to.
2) Connect Logical connection outputs appropriately to Logical AND
connection inputs of the relevant unit.Verify the operation of G9SX-LM
before commissioning the system.
3)
When configuring the safety related system, be sure to consider that the
delay of response time caused by logical connections do not degrade the
safety function of the system.
(13)
To determine safety distance to hazards, take into account the delay of
Safety outputs caused by the following time:
1) Response time of Safety inputs
2) Response time of Logical AND connection input
(See also "Ratings and specifications, note5")
(14) Start entire system after more than 5s have passed since applying supply
voltage to all G9SXs in the system.
(15) G9SX-LMmay malfunction due to electro-magnetic disturbances.
Be sure to connect the terminal A2 to ground.When using a DC power supply
with light curtains, use DC power supply which has no interruption by a power
failure of 20ms.
Connect surge suppressors to both ends of coils of an inductive load to
suppress noise.
(16)This is a class A product. In residential areas it may cause radio interference,
in which case the user may be required to take adequate measures to reduce
interference.
(17) Devices connected to G9SX-LMmay operate unexpectedly.
When replacing G9SX-LM, disconnect it from power supply.
(18)
Adhesion of solvent such as alcohol, thinner, trichloroethane or gasoline on
the product should be avoided.Such solvents make the marking on G9SX-LM
illegible and cause deterioration of parts.
(19)Do not use a CR type of surge suppressor for the inductive load connected to
an instantaneous safety output.This may cause failure or malfunction. It is
recommended to use a diode+Zener-diode type of surge suppressor for an
application for which a response time needs to be allowed.
(20)When reversing the rotation direction of the hazard source during low-speed
operation, allow the hazard source to stop for 500ms or longer before
changing the rotation direction. Reversing the rotation direction without
providing for stoppage time may result in the safety outputs of G9SX-LM
being turned OFF.
(21)Operate the reset input more than 0.4 seconds immediately after the safety
outputs are OFF.
G9SX-LMdoes not accept the reset input from when the outputs are turned
ON and until 0.4 seconds passes after the outputs are turned OFF.
(1) Handle with care
Do not drop G9SX-LMto the ground or expose to excessive vibration or
mechanical shocks. G9SX-LMmay be damaged and may not function properly.
(2) Conditions of storage and usage
Do not store or use in such conditions stated below.
1) In direct sunlight
2) At ambient temperatures out of the range of -10 to 55 °C
3) At relative humidity out of the range of 25% to 85% or under such
temperature change that causes condensation.
4) In corrosive or combustible gases
5) With vibration or mechanical shocks out of the rated values.
6) Under splashing of water, oil, chemicals
7) In the atmosphere containing dust, saline or metal powder.
G9SX-LMmay be damaged and may not function properly.
(3) Mounting

The G9SX-LMcan be used for PL=d and Category 3 required by EN ISO13849-1 European standard.
Refer to the following link for the Safety-related characteristic data:
http://www.fa.omron.co.jp/safety_6en/
However, please note that this does not mean that G9SX can be always used for this category under all similar conditions or situations.
Be sure to assess the entire system for conformity to a required category before use.
For conformity to Safety Category 3, please check the following points;
1) Use both of the two channels for Enable inputs (T11-T12,T21-22), Safety inputs (T61-62, T71-T72), and Rotation detection inputs (D11-D12, D21-D22).
2) Use direct opening action switches for safety inputs (T61-T62, T71-T72).
When limit switches are used, at least one of them should be a direct opening action limit switch.
When connecting a Safety Sensor to the G9SX-LM, use aTYPE3 or 4 Safety Sensor.
3) Use an enabling device, such as grip-switch, for Enable inputs (T11-T12,T21-T22)
4) Connect specified Proximity sensors to Rotation detection inputs (D11-D12, D21-D22)
5)
Apply input signals to T31-T32 for manual reset, orT31-T33 for auto-reset, through the N.C. contact. (Refer to '5. Application Examples)

Relationship between the cogwheel shape and the setting of proximity sensors
• For safe and stable detection of a rotating cogwheel, design of the cogwheel and setting of the proximity sensors should satisfy the following
requirements.
- Either one proximity sensor is turned ON.
- If neither sensor has detected any movement for more than 1 second, G9SX-LM will detect it as an error.
- All cogwheel tooth should be identically shaped.
-The following tables show data for iron cogwheels.
- For further details of the handling of proximity sensors, refer to the operation manual or related documents attached to the proximity sensors (E2E).
• Please connect two proximity sensors of the same type.
• While operation is stopped, consideration must be given so that the cogwheel and proximity sensor do not vibrate due to vibration of the device.
Otherwise the proximity sensor may detect vibration of the cogwheel, resulting in the safety outputs of G9SX-LM
 being turned OFF.
Take appropriate measures to keep vibration of the cogwheel at 1Hz max.
• At the following, G9SX-LM
 diagnoses the proximity sensors.In that case, it is not abnormal though the operation indicator of the proximity sensor
blinks.
- When the rotation of the cogwheel is stopping, and both proximity sensors are turning on.
Relationship between Revolution (rpm) and Frequency
A frequency can be calculated from rpm, as shown in the equation below;
rpm x 1/60 x the number of cogwheel teeth detected by Proximity sensor = Frequency (Hz)
Ex. Low-speed monitoring frequency
With a Low-speed rpm of 50 and 6 cogwheel teeth detected by Proximity sensor,
Frequency = 50 rpm x 1/60 x 6 = 5Hz
Be sure to set the Low-speed monitoring frequency to 6.0Hz or above, considering the accuracy tolerance of the Low-speed monitoring frequency
(within 0 to -10%).
Relationship between Motor, Cogwheel, and Hazard source.
The cogwheel should be attached to the shaft mechanically linking the motor to the hazard source.
The cogwheel should be placed between the motor and the hazard source.
*1. It is a size when the proximity sensors are arranged in parallel.
