Gun Solenoid Wiring
(con ti nued)
Installation 3-13
WARNING: Burns. Unexpected gun firing can occur during
! PC40 installation. The firing can be a response to trigger
signals caused by foreign objects blocking the sensors, and
by intentional and unintentional triggering that can occur
during maintenance. Nordson recommends that you
install
quick-disconnect solenoid leads. Disconnect the leads
during installation
to disable the solenoid. Users may want to
provide an additional measure of safety by disabling the
trigger.
4. Use 16-18 gauge
electrical wire (customer supplied) to make the
connections shown in Table 3.4.
See Figure 3.9 for the location of
terminal block
P2.

{I) Some patterns require more than eight transitions. Two channel outputs can be connected in parallel to a
solenoid. Then you can program both channels' transition
va lues in sequence for a total of 16 transitions.

l If all four solenoid grounds are present, they will not all fit onto P2-3. Connect all the grounds together using a
connector, wire nut, etc. before connecting to
P2-3.
