HE SIGNALS INVOLVED
The machine uses the following control signals:
•
Emergency contact
This is the contact provided by the 2 emergency stop microswitches. They provide a NC contact
which opens when the emergency is pressed. This signal enters the display board (pins 3-6 and
2-6 of connector CN6).
•
RS-485 Signal
This is a digital signal exchanged between the inverter and the display board.
•
Emergency signal
This is the signal generated by the display board (pins 4 and 6 of connector CN6), sent to the
ALE/AT UL driver (pins 9 and 12 of connector J3). This signal is 0 Vdc under normal
conditions, and goes to 11.9 Vdc in the emergency condition.
•
Reset signal
This is the signal generated by the display board (pins 5 and 6 of connector CN6), sent to the
ALE/AT UL driver (pins 10 and 12 of connector J3) to signal to the lower assembly the
resumption of normal operation following an emergency condition. This signal is 0 Vdc under
normal conditions and goes to approximately 8 Vdc for few seconds when the user presses a
key.
When this happens, the display board resets the Emergency signal to 0 Vdc, thereby enabling
the ALE/AT UL driver to operate.
