Operation
Follow these recommended procedures for daily / routine startup and
shutdown to obtain the best performance from your system.
CAUTION
The Pµlse valve is normally open and power must be applied to
close it. 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 de-pressurizing the system if the
signal indicates an error.
Routine Startup
1. If the process requires a heated valve, press the HEATERS icon
and then press ON to switch the HEATERS mode to On.
NOTE: Upon reboot, the controller remembers the last selected
HEATERS mode.
2. Press the VALVE icon and then MODE until the touchscreen
shows the desired operating mode.
3. Start your process.
Purging the System
Press the VALVE > PURGE icons as needed to clear debris or after
changing the uid body assembly. Refer to the valve operating
manual for more detailed information on purging and system
cleaning.
