Logic 8: Partial stop 2 logic for various machinery
Overview (Logic 8)
The logic described is for safety protective measures of equipment which has 2 separate
devices that are stopped by safety outputs independently, such as semiconductor
manufacturing machines, and food packaging machinery. When 2 devices can not be stopped
at the same time or it is not necessary, that 2 safety outputs can be controlled separately. This
logic enables the connection 5 dual channel direct opening inputs.
When in the state in which safety inputs 1, 2, and 3 correspond to safety outputs 1 and 2 can
receive the safety input signals (the contacts of the connected safety devices are ON), the
safety output 1 is turned ON upon input of the start input. When in the state in which the all of
the safety inputs 1 to 5 can receive safety input signals, safety outputs 1 and 2 are turned ON
upon input of the start input.
The safety outputs 1 and 2 are ON, if the input signal to safety inputs 1, 2, or 3 is turned OFF
(the contact of the safety device is OFF), safety outputs 1 and 2 are turned OFF after the preset
OFF-delay time.
If the safety input signal to safety inputs 4 or 5 corresponding to safety output 2 is turned OFF,
safety output 2 is turned OFF.
Note: Refer to "Logic circuit" for the details of safety inputs 1, 2, 3, 4, 5 and safety outputs 1, 2.
