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.

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.

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.
