Nordson EFD Product Safety Statement (continued)
Halogenated Hydrocarbon Solvent Hazards
Do not use halogenated hydrocarbon solvents in a pressurized system that contains aluminum components.
Under pressure, these solvents can react with aluminum and explode, causing injury, death, or property damage.
Halogenated hydrocarbon solvents contain one or more of the following elements.
Element Symbol Prefix
Fluorine F “Fluoro-”
Chlorine Cl “Chloro-”
Bromine Br “Bromo-”
Iodine I “Iodo-”
Check the Safety Data Sheet (SDS) or contact your material supplier for more information. If you must use
halogenated hydrocarbon solvents, contact your EFD representative for compatible EFD components.
High Pressure Fluids
High pressure uids, unless they are safely contained, are extremely hazardous. Always release uid pressure before
adjusting or servicing high pressure equipment. A jet of high pressure uid can cut like a knife and cause serious
bodily injury, amputation, or death. Fluids penetrating the skin can also cause toxic poisoning.

Important Disposable Component Safety Information
All Nordson EFD disposable components, including syringe barrels, cartridges, pistons, tip caps, end caps,
and dispense tips, are precision engineered for one-time use. Attempting to clean and re-use components will
compromise dispensing accuracy and may increase the risk of personal injury.
Always wear appropriate protective equipment and clothing suitable for your dispensing application and adhere to
the following guidelines:
• Do not heat syringe barrels or cartridges to a temperature greater than 38° C (100° F).
• Dispose of components according to local regulations after one-time use.
• Do not clean components with strong solvents (MEK, acetone, THF, etc.).
• Clean cartridge retainer systems and barrel loaders with mild detergents only.
• To prevent uid waste, use Nordson EFD SmoothFlow™pistons.
Action in the Event of a Malfunction
If a system or any equipment in a system malfunctions, shut off the system immediately and perform the following
steps:
1. Disconnect and lock out system electrical power. If using hydraulic and pneumatic shutoff valves, close and
relieve pressure.
2. For Nordson EFD air-powered dispensers, remove the syringe barrel from the adapter assembly. For Nordson

Equipment-Specific Safety Information
The following safety information is specic 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 uid ows out of a valve that is turned off even when no uid pressure
is being applied. If this occurs, it may be because the uid reservoir is positioned higher than the valve, in which
case hydrostatic pressure causes the uid to ow out of a valve that is not closed. Position the uid reservoir low
enough such that no uid 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 uid release. Nordson EFD recommends continually monitoring the status
signal of the Toµch controller and immediately and automatically bleeding the uid reservoir if these signals
indicate an error.
• Before connecting or disconnecting a valve cable, release uid pressure and disconnect and lock out power to the
Toµch controller.

VALVE Screen
The VALVE screen is used to change the operating mode, enter valve dispensing parameters, and control valve
power.
Button or Icon Description
MODE Sets the system operating mode.
Mode Description
Timed In the Timed mode, the valve cycles according to the settings for PULSE (valve open
time), CYCLE (time between deposits), and COUNT (number of deposits) for each
valve initiate signal.
Continuous In the Continuous mode, the valve cycles according to the settings for PULSE (valve
open time) and CYCLE (time between deposits) for as long as the valve initiate signal
is active, ignoring any setting for COUNT (number of deposits).
NOTE: If the system is latched on to a signal in the Continuous mode, you cannot
change screens.
External In the External mode, the controller operates as a slave to an input signal and thus no
longer generates the timing signals required to drive the valve. This mode is typically
used with a device such as the PICO 2+2-XCH-V3 controller for pattern generation.
NOTE: This selection is available only when SHOW VALVE EXTERNAL is toggled
ON via the SYSTEM screen. Refer to SHOW VALVE EXTERNAL under "SYSTEM
Screens" on page 26.
CAUTION
Because the controller does not generate timing signals in the external mode, take
care to not exceed the maximum operating parameters of the connected valve. In
addition, the time setting of any external signal used to drive the valve must be
greater than the RAMP OPEN prole time setting (refer to "WAVE PROFILE Screen"
on page 22). Exceeding timing and valve operational parameters can result in
overall loss of performance.
PULSE Sets how long the valve opens (in milliseconds).
Default: 10 (ms)
Range: Depends on the open prole time and the type of valve being used; as low as 100µs
possible
CYCLE Sets the amount of time between deposits (in milliseconds).
Default: 30 (ms)
Range: 2 (ms) to 9.9999 (s) typical (minimum setting depends on open and close prole times)

Button or Icon Description
COUNT Sets the number of deposits the valve dispenses per valve initiate cycle.
Default: 1
Range: 00001–65535
FREQ (Hz)
(Non-editable)
Provides a color indication to show how fast the valve is operating (in Hz) at the selected
settings; a lower frequency indicates slower operation; a higher frequency indicates faster
operation.
Color Description
Green Safe operating frequency
Yellow Caution—exceeding maximum frequency limits
Red At the border of maximum operating frequency
POWER Sets whether a valve initiate signal is processed and also closes (applies voltage to) the valve.
Valve initiate signals are processed only when valve POWER is ON. By default, valve POWER is
ON when the controller is switched on.
NOTE: The valve is normally open and power must be applied to close it. Always turn the valve
ON before applying uid and air pressure; otherwise, the valve will leak.
ON Valve closed
OFF Valve open
(PURGE)
Purges the system.
NOTE: The PURGE icon:
• Is present only on the VALVE screen.
• Is visible only when valve POWER is ON.
• Functions only if the valve is not dispensing.
• Is disabled if an alarm condition exists.
(CYCLE)
Initiates a dispense cycle. How the system responds varies depending on the mode. Refer to
"Changing the System (VALVE) Operating Mode" on page 31 for more detailed information.
NOTE: The CYCLE icon:
• Is present only on the VALVE screen.
• Is disabled if an alarm condition exists.
