Equipment-Specific Safety Information
The following safety information is specific to the Nordson EFD Toµch controller.
Intended Use
• This equipment is for indoor use only.
• Use the Toµch controller only in conjunction with its associated power cable and, if needed, its associated
extension cable.
• Do not open the Toµch controller.
Unintended Fluid Release
• Prior to initial operation, check to see if fluid flows out of a valve that is turned off even when no fluid pressure
is being applied. If this occurs, it may be because the fluid reservoir is positioned higher than the valve, in which
case hydrostatic pressure causes the fluid to flow out of a valve that is not closed. Position the fluid reservoir low
enough such that no fluid leaks from the valve when the valve is shut off.
• In the case of damage to the piezo actuator or the Toµch controller, the valve may transition from a CLOSED to
an OPEN condition, which can cause fluid release. Nordson EFD recommends continually monitoring the status
signal of the Toµch controller and immediately and automatically bleeding the fluid reservoir if these signals
indicate an error.
• Before connecting or disconnecting a valve cable, release fluid pressure and disconnect and lock out power to
the Toµch controller.

Install the Valve and Controller
The callouts in the system installation images correspond to the steps in
this procedure.
1. Install any components other than the Pµlse valve and controller
that will comprise the complete dispensing system. For example,
if you are using a fluid reservoir, position and install all the fluid
reservoir components. For all ancillary components, refer to the
quick start guide and / or operating manual provided with those
components for installation, setup, and operating instructions.
CAUTION
Ensure that air can flow around the controller. Blocked air flow can
cause overheating.
2. Install or position the Toµch controller. The
controller can be integrated into existing
machinery or used as a tabletop device:
• To integrate the controller into existing
machinery, remove the feet (if needed) and
use the following specifications to install it as a
standard rack mount:
- Height: 3U
- Width: 28 Hp
- Depth: for 160 mm (6.3")
• To use the controller as a tabletop device, lower
the hinged legs.
• Ensure there is adequate air flow around the
controller.
3. Connect power to the controller as follows:
a. Connect power to the back of the controller
and to your local power source observing the
following guidelines:
• Use only the supplied power supply and
power cord.
• Ensure that the power source is located
near the equipment and is easily
accessible.
• Use only on a circuit with a fuse or circuit
breaker that is 20 A or less.
b. Connect a 16 AWG (1.3 mm) ground wire to
the chassis grounding screw on the rear of the
chassis using a toothed grounding lug. The
wire must have green insulation with a yellow
stripe or must be non-insulated (bare).
c. Attach the opposite end of the ground wire
to a permanent earth ground using toothed
washers or a toothed lug.
3b
3a
CAUTION: Nordson EFD requires that
the provided power cord be used with the

Install the Valve and the Controller (continued)
CAUTION
Always switch OFF the Toµch controller before connecting or
disconnecting the valve. Failure to do so can damage the controller and
the valve.
4. Assemble and mount the Pµlse valve as follows:
a. Open the hinged seat of the piezo actuator by pushing the latch
pin back towards the valve.
b. Insert the fluid body assembly and close the hinged seat,
ensuring it is fully engaged.
4b4a
c. Referring to the guidelines below, install the Pµlse valve on the dispensing equipment:
• Nordson EFD strongly recommends using a valve mounting bracket. There are multiple mounting holes
to allow for adjustment. Some valve mounting examples are shown below.
• For repeatable mounting-location precision, use alignment dowels to mount the valve by the frame side.
• When mounting the valve, do not install bracketing that could apply pressure to either side panel. Doing
so can damage the piezoactuator, compromising valve performance.
• When mounting a Pµlse XP valve, ensure that the fluid supply feed loads are properly supported to
prevent movement of the fluid body assembly. For Pµlse XP valves, proper mounting is critical to
ensure correct operation. Forces applied to the valve where the fluid supply attaches can cause strain
movements of the fluid body assembly, which can result in calibration errors if the strain movements are
too large (alarm code b17 020 on the Toµch controller).
NOTE: Valve mounting kits are available. Refer to the valve operating manual.

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
Cables (Standard Toµch Controller)” on page47 for available
extension cables.
NOTE: The VALVE power and communication ports differ on
the ToµchXP controller, so different valve extension cables
are required. For ToµchXP controller extension cables, refer
to “ToµchXP Valve Extension
Cables” on page75.
e. To divert static charges from the
valve, connect it to the machine
system ground. Vacant fastening
threads may be used for this.
f. 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.
5. 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 exceeds +45° C (113°F).

CAUTION
Do not dry cycle the Pµlse valve! The ceramic nozzle seat and ball can
be damaged if the valve is operated without fluid, causing leakage and a
poor seal. Precise dispensing can no longer be guaranteed if this occurs.
6. Start up and test the system as follows:
a. Switch the Toµch controller power ON and complete the
touchscreen calibration as prompted (required only at
initial startup).
b. (Heated systems only):
• Press the HEATERS icon ( ) and then enter a
temperature SETTING that is just above the ambient
temperature (or as appropriate for the fluid).
• Press ON to switch the HEATERS mode to On.
• Wait for the system to reach temperature setpoint.
NOTE: The HEATERS screen shows the actual
temperature of the valve.
c. IMPORTANT: Press the VALVE icon ( ) and then press
POWER to switch the valve ON.
d. Introduce fluid to the system.
e. Set the reservoir pressure lower for thin fluids and higher
for thick fluids [approximately 0.4–1.0 bar (5–15psi),
depending on the fluid]. For tanks, use the in-line air
shut-off valve to pressurize or de-pressurize the fluid
supply. For syringe barrels, connect or disconnect the
adapter assembly from the reservoir pressure regulator
and gauge.
f. Press the PURGE icon ( ) and allow fluid to purge from
the system until the fluid flow is steady.
g. Press MODE and enter the following recommended
settings to test an actual deposit:
• MODE = Timed
• PULSE = 0.5 (ms)
• CYCLE = 5 (ms)
• COUNT = 10
h. Press the CYCLE icon ( ).
The system dispenses 10 deposits and displays the
frequency (FREQ) indication on the VALVE screen.
i. Make parameter adjustments until the desired deposit
result is achieved. Use caution not to exceed maximum
frequency ranges.

User Interface
The controller is operated through an easy-to-use touchscreen interface. This section provides an overview of the
user interface and all the controller’s screens and menus.
Navigation and Screen Structure
All system controls are accessed through the icons and buttons on the touchscreen. Each screen includes icons
that allow you to jump quickly to other main screens. Each screen also shows the current LCD display version and
the system UpTime, which is an indicator of how long the controller has been active or operational. The UpTime is
specifically used to track when alarm conditions occur in the controller.

• Module / screen name
• Up Time: How long the controller has
been ON.
Alarm Indication
The title bar blinks red anytime an alarm condition is detected, regardless of the type of alarm. For example, if a
POWER alarm occurs when the VALVE screen is open, the title bar blinks red even though the alarm is not a valve-
related alarm. To view the alarm type, touch the title bar.
