Emergency Stop Circuitry
6.4 Emergency Stop - Reset Circuit
The Emergency Stop Reset circuit uses the Motors
OFF push button. When the Motors OFF push button is
pressed:
- 24 VDC goes from the back plane X34 pin 24.
- To the Control Panel’s Motors OFF push button
terminal 14.
- When the button is pressed, 24 VDC will go through
to terminal 13.
- Back to the back plane X34 pin 9.
This is where the computer picks up the signal as
Emergency Stop Reset and allows K2CR on the System
board to close when attempting to turn the motors ON
after an emergency stop.
