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")
3) Preset off-delay time
4) Accuracy of off-delay time
(11) Start entire system after more than 5s have passed since applying

(12) G9SX 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.
(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.
(15)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.
(16) Operate the reset input more than 0.4 seconds immediately after the
safety outputs are OFF.
G9SX does not accept the reset input from when the outputs are
