How ORS SITEPRO™ works
The ORS SITEPRO™ 2000 uses highly flexible microprocessor based electronics to provide a wide spectrum of
capabilities that range from basic motor control to complex and sophisticated multi-panel networking. This built in
versatility allow the ORS SITEPRO™ 2000 to be configured on site to match the unique requirements of any remediation
application.
Basic Motor Control
Figure 3, shows a simple water treatment system in which an ORS SITEPRO™ 2000 Blower/Pump panel controls a
LOPRO™ Air Stripper blower and a transfer pump. During normal operation, the blower runs continuously and the pump
cycles on and off in response to input from the sump level probe mounted in the Air Stripper sump.
Motor Control with Interlocks
In most applications, your ORS SITEPRO™ 2000 will be integrated into a remediation system that includes additional
equipment components.
Figure 4
These components (holding tanks, hydrocarbon pumps, oil/water separators, carbon tanks, etc.) often must be interlocked
to the control panel to optimize system performance and to prevent permit excursions in the event of a component failure.
Figure 4, shows another simple water treatment system in which contaminated water first passes through an Air Stripper
and then into a Carbon Tank. Again, the ON/OFF cycling of the transfer pump is controlled by the status of the sump
probe. In this application, however, a high pressure switch is wired to the control panel shuts off the transfer pump if the
carbon tank becomes clogged. Use of such external
interlock devices (high level shut off switches, pressure switches,
etc.) is facilitated by a system of internal circuits built into every ORS SITEPRO™ 2000 panel. These circuits provide four
separate
alarm channels for attachment of interlock devices.
Multi-Panel Networks
When two or more ORS SITEPRO™ 2000 panels are linked together in a network as shown in figure 5. The individual
panel microprocessors are able to communicate and share information through a system of circuits called the Interlock
Communication Bus, or ICB. Each panel in a network can be configured to send and/or receive alarm signals on any or
all of the four alarm channels . In this way, alarms received locally by one panel can be broadcast on the ICB and used to
shut off other panels in the network.
In figure 5, a feed pump and its control panel (Panel #2) have been added to the water treatment system diagrammed in
figure 4. Panel #2 receives input from its own level sensing probe and Panel #1 through the
network cable shown in the
