3.24. EMERGENCY STOP SIGNAL MANAGEMENT
3.24.1. LED – VISIO/VISIOWEB
The device consists of a button fitted below the display of the machine, which is composed by 2 NC
micro switches connected in series. On the same button is connected a rope: if pulled act exactly as
when you press the button.
If a user is in difficulty and press the emergency device from the control panel or pull the emergency
rope, the NC contact is opened then the CPU/ARM board realize about the emergency status.
3.24.1.1. Control logic
The control block diagram is as follows:
Emergency
Scheda CPU
RS-485
CN22
Keyboard
Driver
Restore Emergency
Key
Contact
CN17
J3A
When the user press the emergency stop device, the NC contacts is opened, changing the state of the
two signals output by them to the CPU. Each of the two micro switch outputs a distinct signal,
interpreted as follows: one is an “
SW Emergency ” signal, and one is an “ HW Emergency ” signal.
The two signals are managed as follows:
SW Emergency: The CPU board detects the emergency condition and signals it by
displaying the message “Reposition the emergency stop device and touch the screen” and
sends the information to the drive over the 485 serial link to halt the motors..
HW Emergency: The CPU board sends the emergency signal directly to the drive to halt
the motors.
To reinstate the machine's operation, it is necessary to reposition the emergency stop device on the
control panel and press any key on the display, as prompted.
