Standard System Components
Standard primary components of the NJEX-7300G
include the following:
• System Enclosure, figure 1. Houses the Model
7000F pump, the Model VM-1100 Verometer, the
odorant fill valve, the solenoid valve/pneumatic
relay manifold, the odorant discharge manifold, the
system control enclosure, *power supply enclosure,
and bulk odorant filter.
• *SPS12 Solar Panel Assembly, figure 1. The stan-
dard solar panel for the 7300G is equipped with a
mounting bracket and a connection cable.Optional
LPS-120/240 may be used in lieu of the solar panel.
• System Control Enclosure. Houses the N-300G
controller. (Not illustrated)
• *Power Supply Enclosure. Houses the battery, char-
ger supply, and I.S. Barrier. (Not illustrated)
• Bulk Odorant Filter, figure 3. Provides primary
odorant filtration between the storage tank and
the NJEX-7300G. The Bulk Odorant Filter is pre-
installed inside the System Enclosure attachment to
the odorant source is via an odorant inlet manifold
equipped with 1/4" FNPT connection located on the
back of the System Enclosure.
• Service Tray, (Not Illustrated), should be installed in
the bottom of the system enclosure, to capture any
drops that may occur during servicing of the odor-
izer.
• Mechanical Cabinet Cable, figure 3. Provides the
connection between the system control enclosure
and the electrical components in the mechanical
section.
• Expansion Tank, figure 2. Provides a closed loop
system for pressure fluctuations within the Verom-
eter during the odorant fill/injection cycle.
• NJEX Gas Filter, figure 2. Installed between the
actuation gas regulator and the actuation gas mani-
folds, this filter provides a 25 micron coalescent
filtration to insure a clean pneumatic supply.
• Actuation Gas Regulator, figure 3. Provides addi-
tional regulation of supply gas to actuate the pump.
