The machine will not accept any commands until the emergency stop device has been
correctly repositioned.
The two sensors connected in parallel provide redundant safety, outputting two distinct and
independent signals to the Display Board, however the malfunction of any one of these two sensors
causes the machine to stop functioning in an emergency condition.
ATTENTION: The message “Reposition the emergency stop device and touch the
screen” appears on the display also if the serial communication between the high and
low kit is interrupted.
Pressing a key initiates the procedure for reinstating operation of the Drive, which receives a reset
signal from the Display Board. After this, the Drive attempts to re-establish serial communications
with the Display, and then repeats the reset procedure again.
If serial communication cannot be established, the machine will make a number of attempts. Each
failed connection attempt is recorded in the COM FAULT parameter, which can be viewed as
described in the relevant paragraph of the Service menu. After approximately 30 seconds, it stops
and displays the error message “MACHINE LOCKOUT (COM)”.
3.16.2. THE SIGNALS INVOLVED
The machine uses the following control signals:
Emergency contact:
This is the NC contact provided by the 2 magnetic sensors actuated when the emergency stop
device is detached. This contact becomes open when the emergency stop device is detached.
The signal enters the Display Board through connector CN22 (pins 1 and 2).
RS-485 Signal:
This is a digital signal exchanged between the Drive and the Display Board.
Emergency signal:
This is the signal generated by the Display Board (pins 1 and 4 of connector CN17) and sent to
the Drive (J3A).
This signal is 0Vdc under normal conditions, and goes to 11.9Vdc in the emergency condition.
Reset signal:
This is the signal generated by the Display Board (pins 1 and 10 of connector CN17) and sent to
the Drive (J3A) to signal to the low kit that normal operation has been reinstated after an
emergency condition. This signal is 0Vdc under normal conditions and goes to approximately
8Vdc for a few seconds when the user presses a key.
When this happens, the Display Board resets the Emergency signal to 0Vdc, thus allowing the Drive
to return to the normal operating condition.
