but if the emergency is tripped the contact opens and the inverter, which is no longer supplied, stops
driving both the tread belt and elevation motors.
Once the elevation board has received an alarm signal, even if the emergency reverts to the non-
tripped state, the alarm condition will persist until the digital plan board sends a reset signal
resulting from the “Clear” key being pressed. This reinstates the power supply to the inverter which
can thus resume driving the tread belt and elevation motor, in accordance with the commands
received via the serial RS-485 link from the digital plan board.
3.4.2. THE 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 digital plan board (pins 3-6
and 2-6 of connector CN9). When the digital plan board detects an open emergency contact, it
signals an emergency condition to the display with the “EMERGENCY STOP” message and
sends an emergency signal to the lower machine assembly.
• Emergency signal
This is the signal generated by the digital plan board (pins 4 and 6 of connector CN9), sent to
the download board (pins 9 and 12 of connector X1) and finally sent to the elevation + cut-out
board (pins 2 and 3 of connector X4) to signal an emergency condition to the lower assembly.
This signal is 0 Vdc under normal conditions, and goes to 11.9 Vdc in the emergency condition.
• Enable signal
This is the signal generated by the elevation + cut-out board (pins R
+
and R
-
) and sent to the
relay (pins 0 and 1) to energize the coil. This signal is 11.7 Vdc if the emergency signal is at 0
Vdc (normal conditions), and it goes to 0 Vdc if the emergency signal is 11.9 Vdc (emergency
condition).
When the relay coil is energized its contact is closed and the 220 VAC mains supply on contacts
4-8 is output on contacts 2-6, from which it supplies the inverter on pins L1 and L2.
• Reset signal
This is the signal generated by the digital plan board (pins 5 and 6 of connector CN9), sent to
the download board (pins 10 and 12 of connector X1) and finally sent to the elevation + cut-out
board (pins 4 and 3 of connector X4) 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 when the user presses the “Clear” key.
When this happens, the digital plan board resets the emergency signal to 0 Vdc, thereby
enabling the relay contact to close and hence supplying the inverter.
• RS-485 Signal
This is a digital signal exchanged between the inverter and the digital plan board. There is no
way to monitor its state other than through the LEDs on the Download board. Through this link,
when the emergency is pressed the digital plan board halts the motor movements by means of
the inverter.
