18 Safety
To lock out/tag out pneumatic pressure:
1. Verify that all dispensing motion has stopped.
2. Lock out and tag out AC power as specified earlier in this section.
 When the power is shut off, the main air solenoid valve shuts off and all air pressure
inside the dispensing system is automatically released.
3. Locate the main air pressure regulator adjustment knob.
4. Unlock the knob by pulling it out and then rotate the main pressure regulator adjustment
knob counterclockwise until the main air pressure gauge registers 0 psi.
5. Disconnect the facility air supply hose from the main air inlet and place a warning tag on the
main air inlet.
2.9 Interlock
When the interlock circuit is open, the Interlock immediately stops all dispensing activity to protect the
operator from injury. The Interlock is an electronic connection to the motor processor and power, as well
as the discreet and general purpose I/O and the solenoid drivers, that immediately cuts the power to any
motion and to any peripheral (I/O or solenoid driver). The intended use of the interlock is to prevent
physical injury (to the operator) from system motion while the operator is in the work area.
The recommended use of the interlock is with the Nordson ASYMTEK optional enclosure
(D-583: P/N 7207733 D-585: P/N 7207735) and Start Button Box (P/N 7207732).
2.9.1 Interlock Recovery
When the interlock has been triggered, FmXP will display an interlock active message (Figure 2-4). To
recover from an interlock shutdown, close the dispensing area front doors. When the FmXP Message
32691 appears (Figure 2-5), click OK to continue dispensing or Cancel to abort.
