If the telecommunication option is installed in one of the panels in a network, that panel must be configured as the
Master. However, if no remote monitoring is required, any panel in the network can be the Master. Panels are
designated Masters or laves by setting dip switches inside each panel.
During network operation, the Master continuously polls the laves in a set sequence determined by the network
addresses the user chooses for the panels. When a lave is polled, it is temporarily given control of the Interlock
Communication Bus. The lave then broadcasts any current interlock alarms that are on alarm channels configured
to send. All other panels in the network ( laves and Master) will then respond to the alarms and shut down if they are
configured to receive on these same alarm channels.
tep by step procedures for configuring your OR ITEPRO™ 2000 Control Panel are provided in Chapter 3 of this
manual.
Additional Applications
The examples in this chapter have shown the OR ITEPRO™ 2000 Blower/Pump Control Panel being used to control
an air stripper blower and a transfer pump. Additional OR ITEPRO™ applications are listed on the following page:
Air Stripper w/Influent Feed Pump
When used to control an air stripper blower and an influent feed pump, the OR ITEPRO™ receives input from the air
stripper controls (sump probe & pressure switches) and a water pump level sensing probe. In this application, the normal
cycling of the feed pump is controlled by the level sensing probe. When the panel is properly configured, the pump can be
shut off by 1) a LOW-OVERRIDE signal from the level sensing probe, 2) a HI or LO PRE URE signal from the blower,
3) a HI UMP signal from the air stripper sump level probe or 4) an alarm generated by an external interlock device.
Air Stripper w/Chemical Feed Pump
When used to control an air stripper blower and a chemical feed pump, the OR ITEPRO™ receives input from the air
stripper controls (sump probe & pressure switches) and a level sensor mounted in the chemical vat. In this application,
operation of the chemical feed pump is controlled by the vat level sensor. The pump can be shut off by 1) a LOW-
OVERRIDE signal from the vat level sensor, 2) a HI or LO PRE URE signal from the blower, a HI UMP signal from the
air stripper sump level probe or 4) an alarm generated by an external interlock device.
SVE Blower w/ Knockout Drum
When used to control a soil vapor extraction ( VE) blower with a knockout drum, the OR ITEPRO™ receives input
from a knockout drum high level switch. In this application, the blower can be shut off by the high level switch or by any
external interlock device wired to one of the panel’s alarm channels.
