RF Detector
See Figure 3-2.
S One RF detector is normally required for every
16 networked units within one curing enclosure.
However, some applications and systems may
require an RF detector on each unit. Contact
your Nordson representative for more
information.
S Mount the RF detector so that the antenna
faces the lamphead screen and is between the
operator and the lampheads or the lampheads
and any opening (the major source for RF
leakage).
S The minimum distance should be eight inches
to prevent excessive heat on the detector
surface.
S Do not mount the RF detector directly below the
lamphead.
S For RF detector connections, refer to RF
Detector on page 3-9.

Lamphead Cooling
Lamphead cooling is critical to the operation of the
lamphead. There are two types of lampheads
available:
Internal Blower: requires no external cooling
air.
Remote Blower: requires an external source
of cooling air ducted to each lamphead.
The following specifications must be maintained for
all applications at all times regardless of which type
of lamphead is used:
S unimpeded and unrestricted flow of cooling air
through the lamphead
S constant static pressure of 7-in. water column
from the inside of the lamphead to ambient or
the lamp face
S 350 CFM of airflow through the lamphead
If you are using an exhaust box or any other type of
lamp face attachment that can impede the airflow
through the lamphead, you must monitor the
pressure and CFM on the lamp face.
The cooling air flow, static pressure, and CFM
requirements must be maintained. If not, the life
lamphead will be greatly reduced with the
possibility of failure.
For more information on lamphead cooling, contact
your Nordson UV representative.
