3.5.3 ELECTRICAL TOUCHSCREEN
CONTROLS
the main control panel for the SHM unit is a touchscreen
interface located integrally on the front of the unit or
remotely in an auxiliary enclosure (refer to section 3.5.4)
that operates the blower.
the touchscreen control panel is powered by 24V dc.
refer to Section 4 of this manual for operation of the
touchscreen. all wiring in the touchscreen controls panel
is pre-wired at the factory and there are no customer
connections at this panel. the panel door should remain
closed and locked during operation.
3.5.4 ELECTRICAL REMOTE PANEL
CONTROLS
Both the Basic and touchscreen controls can be
mounted remotely from the unit. The max distance is
100 ft (30.5 m). the controls are provided in a neMa 4X
enclosure for mounting.
Basic controls – the remote controls panel/enclosure will
contain the blower speed adjusting potentiometer inside
the enclosure, and an on/off switch on the cover. this
enclosure will be attached to the SHM unit at the factory
with 50ft of wire. the cable can be cut down in length at
the time of installation if needed by disconnecting the wire
from the remote panel, cutting to length, and reconnecting.
use the wire diagram on page a2 for reference.
touchscreen controls – the remote touchscreen controls
enclosure will contain the touchscreen and terminal blocks
for the wire connections. there are two cables connected
to the remote enclosure that are 100ft each. one is the
24 Vdc power supply and control cable, and the other
is a communication cable. these wires will need to be
connected to the rear control panel of the SHM unit by the
customer at the time of installation. the first wire is the
low voltage controls wire that will connect to the terminal
blocks in the back of the SHM unit on +24Vdc, -24Vdc,
an2, an3, an4, i0, and o0. use the wire diagram on page
a6 for wire colors and terminal location for landing. the
second wire is a communication wire that needs landed in
the WaGo 222 Lever Wall nuts. Match the colors of the
wires, brown with brown and black with black.
3.5.5 MACHINE INTERLOCK DRY CONTACT
the customer has the option to control the SHM on/
off operation with the oil mist generating equipment or
process. this will allow the operator to control the SHM
with a dry-contact off another piece of equipment. refer
to the wiring diagrams in the appendix for wiring of this
option and to Section 4 for Machine interlock set up on
the touchscreen.
Wiring will be terminated to the terminal blocks located in
the rear electrical panel in figure 1B When the machine
dry contact is closed, the SHM blower will be on and when
the contact is open, the SHM unit blower will shut down.
Note: a relay coil cannot be connected to the SHM and
will not work for this type of electrical circuit.
3.6 FILTER INSTALLATION
the primary filter elements are shipped already installed
in the SHM unit. if an after-filter option is selected by the
customer, those filters will be shipped separate of the unit
to be mounted following unit installation at the customer
facility. filters may removed from the primary filter cabinet
by the customer when delivered to lessen weight, protect
them from damage, and ease unit installation.
Proper removal and installation of each filter type is shown
in figures 5a & 5B.
3.6.1 INSTALLATION PROCEDURE FOR
AFTER-FILTERS
3.6.1.1 HOLD DOWN
center the filter(s) atop the unit when viewed from the
front. if the unit is two filters deep, then the two after-filters
will be butted against each other in the center of the unit
(looking at it from the side) from front to back just as with
the internal filters.
the hold-down brackets are to be placed on top the filters
as shown in figure 5a balloon #7 and secured down with
all-thread rods, washers and nuts. tighten nuts using
hand tools and be sure not to over compress the gasket
on the bottom side of the after-filter. Minimal torque should
be applied; just enough to cinch down each bracket so it
will not slide around on top of the filter(s). on units two
filters deep, a center bracket is also supplied that runs in
the same direction, it is placed immediately over the seam
where the two filters are butted together.
Larger size unit after-filter setups will be installed in an
identical fashion. the filters will always be installed in-line,
directly over the perforated square cutouts on the top
panel.
