Precipitator Control for the Power Industry
Integrated Precipitator Management System (IPMS)
The Forry IPMS ties together voltage controls, rapper controls, a Windows user interface, and additional I/O signals in a complete, integrated package.
A system consists of these major components
Automatic Voltage Controls
Voltage controls such as the AVC XM, AVC9000, AVC6001 and AVC6000 are daisy chained together to a DCU via RS-485 connections.
ERC1001 Rapper Controls
The ERC 1001 rapper control consists of a Eurocard rack with a customizable collection of CPU, communications, display, firing and I/O cards. The ERC1001 rapper controls are linked together using fiber optic cable and then the master ERC control is linked via fiber optics back to the DCU.
Dataserver
Dataserver is a Windows application that runs in the background and automatically logs AVC and ERC values and alarms to an industry standard Microsoft Access database. Dataserver connects to the DCU via an RS-232 link.
AVCWin / ERCWin / DCUWin Workstations
Each of these graphical user interfaces can connect to Dataserver to perform control, configuration, and diagnostics functions as well as viewing log and status data. Any number of clients running any of these programs can connect to Dataserver over your plants network, so you can view your ESP status at an instant from the control room or your office, or even remotely.
Distributed Control Unit (DCS)
The DCU consists of a Eurocard rack with a CPU, communications card and optional I/O. The DCU ties everything together, passing communications between rapper controls and voltages controls for power off rapping, collecting ERC and AVC polling data and providing advanced functions such as opacity, boiler load and time of day control to the ERC and AVCs.
MIU1001 (optional)
The MIU1001 provides MODBUS communications capabilities to the system. It connects via fiber optic cable to a DCU and allows both polling and control of ERCs and AVCs from a plant DCS or via OPC.
