(O - P) IR Furnace Standard Features and Options

IR Furnace Features

Base Equipment and Options (O - P)

KEY	DESCRIPTION
OA	Oxygen Analyzer: Provides an oxygen monitoring system for the process atmosphere in a furnace with a hermetic sealed chamber. A gas sample is withdrawn continuously from a sample port in the furnace chamber through the analyzer. A switched pump and vacuum break are provided to withdraw the sample. The analyzer is provided with an inline 1 μm filter for removal of particulates from the sample flow. On computerized systems ProControl™ OIT displays oxygen concentration in PPM, and alert/alarm conditions. Also offered as stand-alone system and can be integrated with OSS for multiple ports on LA-306 models. Requires OSS-On-line Gas Sampling. System, option available on most furnaces.
OI	Operator Interface. Operator Interface also known as MMI (man machine interface), and HMI (human machine interface). OI refers to the furnace graphical display software that the operator uses to communicate with the furnace PLC and to observe data collected by the Furnace PLC. Furnace graphical interface software that allow the user to view and modify furnace operating parameters and communicate with the PLC. Standard on most furnaces.
OIT	Operator Interface Terminal. OIT refers to the Dell Optiplex RAID1 furnace computer that the operator uses to communicate changes to the furnace PLC and to observe data collected by the Furnace PLC. Furnace computer and monitor are wired to stay “ON”, regardless of control panel ON/OFF pushbuttons, as long as power is supplied to furnace. This arrangement allows reliable startup and shutdown of the furnace computer, allows use of the furnace computer without powering up the furnace, and extends furnace computer life and reliability. Requires OI. Standard on most furnaces.
OS7	Windows7 Operating System. Microsoft Windows7™ operating system on the OIT. Operating system configured for XP ease of use. Standard on most applications.
OSS	On-line Gas Sampling System: The sampling system provides 4 selectable inputs: 3 sample ports in the furnace and 1 port with a 13.7 kPa (2 psi) regulator in-line for source gas monitoring or sensor purging to improve sensor response during startup of sampling. System may be turned on/off and any of the 4 inputs selected via the furnace OI. Required for OA and MA options, option available on most furnaces.
OSXP	XP Operating System. Microsoft WindowsXP™ operating system on the OIT. No longer supported by Microsoft®.
OT	Over-temperature Monitor & Shutdown Alarm. Provides completely independent temperature measurement in each zone with audible alarm and automatic furnace shutdown for temperatures out of range. Includes second thermocouple for each zone directly connected to separate zone scanner and monitor with display. Alarm integrated with the furnace OI. Option available on most furnaces
PC	Computer, Managed Platform. PC configured to act as the interface the operator uses communicate with the furnace PLC, store process recipes, log furnace behavior and reinstall furnace software. Includes dual drives in RAID1 array and dual Ethernet network interface ports. Standard on most furnces.
PCM	Monitor, LCD. Standard 4:3 aspect ratio, 17 inch LCD monitor professional monitor with integral USB ports and swivel stand. Standard on most furnaces.
PCMS	Computer Monitor, Special.Special order monitor to suit custom application. Option available on most furnaces.
PF-SS	Stainless Steel Plumbing and Fittings. Stainless steel gas line components, standard on hydrogen furnaces and high pressure lines supplied before GSM regulators. (Note: Aluminum gas tubing and brass fittings are standard for most applications.) Option available on most furnaces.
PH1	Product Height, 1 inch. Reduces clearance at all baffle and cooling section throats, and zone dividers ) to 25 mm (1 inch) from the standard 51 mm (2 inch). Allows for larger zone-to-zone temperature differences for small parts. Option available on most furnaces.
PH2	Product Height, 2 Inches. Standard furnace clearance allows a maximum of 50 mm (2 inch) high product to pass through all baffle and cooling section throats, and zone dividers. Standard on all furnaces.
PH4	Product Height, 4 inch. Raises clearance at all baffle and cooling section throats, and zone dividers to 102 mm (4 inch) from the standard 51 mm (2 inch). Option available on most furnaces.
PLC	Programmable Logic Controller. The 32-bit industrial computer that controls the actual operation of the furnace. It sends and receives analog and digital signals from the furnace to control the furnace behavior. On OIT equipped furnaces, programming of the PLC is performed from the PC. Standard on most furnaces.
