(12) Power Supply
1. The G9SX may malfunction due to electromagnetic
disturbances. Be sure to connect terminal A2 to ground.
2. When sharing a power supply with a Safety Light
Curtain, use a power supply that will not fail for a
momentary power interruption of 20 ms or less.
(13) Devices connected to G9SX may operate unexpectedly.
When replacing G9SX, disconnect it from power supply.
(14) Adhesion of solvent such as alcohol, thinner,
trichloroethane or gasoline on the product should be
avoided. Such solvents make the marking on G9SX
illegible and cause deterioration of parts.
<G9SX-NS/-NSA, D40A>
For details, refer to D40A/G9SX-NS catalog (Cat. No. C160).
( 1 ) Connection with Non-contact Door Switch
Wire conductors between the G9SX-NS @ and the D40A
Non-contact Door Switch correctly and verify operation,
before using the system.
( 2 ) The D40A must be used with a designated actuator and
G9SX-NS @ Controller.
( 3 ) Use cables with a length of less than 100 m total to connect
D40A Switches.
( 4 ) Disconnect the G9SX-NS @ from the power supply when
replacing the D40A. Devices connected to the G9SX-NS @
may operate unexpectedly.
( 5 ) Do not use the D40A in a magnetic field of 1.5 mT or
higher. The D40A may not function properly.
( 6 ) Do not use the D40A in the water or in an environment
continuously exposed to water. Water may penetrate into
the D40A. (The IP67 degree of protection for this switch
means that it has been checked for penetration of water
after having been left in water for a fixed period of time.)
( 7 ) Be sure to mount a guard stopper and guide to prevent the
D40A Non-contact Door Switch from being subjected to
impact.
( 8 ) Do not use the switch or actuator as a stopper. Protect the
switch and the actuator by installing a stopper. Separate
the switch and the actuator to a distance of 1 mm or more.
( 9 ) Install the actuator and switch at an appropriate distance
so that they do not create a gap that provides access to the
hazard.
(10) Where two or more Switches are mounted side-by-side,
they must be no closer than 25 mm.
(11) Check that the machine is stopped whenever the
interlocked guard door is open.
(12) Do not mount the switch and actuator on magnetic
materials, otherwise it may affect the operating distance.
Below are reference values of the effect to the operating
distance.
(13) Tighten all screws to the specified torque by using non-
magnetic M4 screws and washer for the installation of the
switch and actuator. After installation and using, the
actuator and switch fixing screws must be coated with
tamper proof varnish or similar compound. Using
anaerobic locking compounds can have a detrimental
effect on the plastic switch case if the compounds come
into contact with the switch case.
(14) Wiring
1. Use the following to wire to the product.
Stranded wire (flexible wire): 0.2 to 2.5 mm 2 (AWG24 to
AWG12)
Solid wire (steel wire): 0.2 to 2.5 mm
2 (AWG24 to
AWG12)
2. When an auxiliary output is not used, cut off the wiring
and cover it with tape so that it does not contact other
terminals.
<G9SX-GS>
( 1 ) Use a mode selector that has an SPST-NO + SPST-NC
contact form (e.g., OMRON's A22K- @ -11).
Total wiring length 100 m max.
