Do not exceed the maximum extension cable length of 9 m (30 ft).
Doing so will adversely affect communication between the valve and the
controller.
CAUTION
Do not connect or disconnect a
Pµlse
XP valve cable to a
Toµch
XP
controller when the controller is powered ON. Doing so can cause a b11
error and possibly damage the valve or the controller.
CAUTION
d.
Ensuring that the controller is powered OFF, connect the
valve power and communication cables to the connectors on
the back of the
Toµch
controller. Refer to “Valve Extension
Controller)” on page 47 for available
extension cables.

To divert static charges from the
valve, connect it to the machine
system ground. Vacant fastening
threads may be used for this.

Add the fluid supply, but do not
pressurize the fluid supply at this
point.
NOTE:
For low viscosity
fluids used in a syringe barrel
application, fill the barrel after
installing it on the fluid-inlet
fitting. High viscosity materials
can be loaded into the barrel
before installing it on the inlet
fitting.

Connect inputs / outputs (I/O) to I/O 1 and I/O 2 as needed for your operation. Refer
to “Input / Output Port Pin Descriptions” on page 53 for detailed I/O information. A
15-position D-sub and backshell are provided. A cable for the 25-pin D-sub connection is
customer-supplied.
NOTE:
Nordson EFD recommends using the analog temperature output (I/O 1, pin 11) to
provide operators with appropriate identification and protection against contact when the
valve temperature e45° C (113° F).
