AVAILABLE OPTIONS & ACCESSORIES
Pressure Gauge Kit: PN 101175
An optional analog pressure gauge can be mounted on the outlet filter manifold. Reading the adhe-
sive pressure at the manifold, rather than in-line on a hose, allows for more precise monitoring of
system pressure. It is also useful for troubleshooting and maintenance.
The gauge is installed at one of the adhesive ports on the manifold (see illustration on page 3-7).
Though there is no “dedicated” port for the gauge, ports #2 or #4 are preferred. Fittings are included
in the kit.
Drop-in Grids: PN 680089
The drop-in grid is an extra heated grid which is installed near the bottom of the ASU’s hopper. The
additional grid allows faster melting of adhesive for applications requiring higher melt rates and
higher volumes of adhesive.
Filter Options
150 Mesh Outlet Filter: PN 106273
Some situations call for a finer mesh outlet filter. A “dirty” adhesive or one with a short pot life are
examples. Systems utilizing very high temperatures or systems running in a dusty environment also
benefit from a 150 mesh filter. Standard equipment is a 100 mesh filter (PN 101247).
Pressure Transducer Assembly: PN 680545
A pressure transducer is an electronic probe that allows the melted adhesive’s pressure to be pro-
cessed by the ASU’s control system and displayed on the HMI. They are used to monitor system op-
erating pressures and their limits. They troubleshoot clogged nozzles and filters.
Level Control Assembly : PN 680614
This device informs the operator, via a message on the DynaControl’s readout and an audible signal,
that the hopper’s adhesive level is low. It may also be wired to stop production, turn on an alarm
light or signal a PLC at a low adhesive level.
Pneumatic Pressure Relief Valve (PPRV): PN 680424
The pneumatic PRV provides gear pump units with a method to automatically relieve adhesive pres-
sure (to zero) by turning off air supply to the ASU.
